OM contributions shared by NOCs - but..

gene doping research $3m

gene doping panel in WADA, help with detection

new results - WADC, mar 2003 -

ME: who are stakeholders of gene doping?

Olympic charter amended stating that only countries signed to  WADC can participate in Olympics

UNESCO convention Oct 19 2005 120 supporting states, observed by all 191 states

gov actions - now wider gov support

gov can do sth sports cannot sports cannot address trafficking, seizing, regulation of med professionals

trying to widen network of stakeholders recently, an athlete committee athlete outreach committee

gene doping inevitable

athletes believe they are immune to risk and their entourage seem not to care

New Trends in Anti-Doping Arne Ljungqvist

need to be ahead of the game first time in history

purpose - describe recent developments

some key years 1960 olympic games in rome - danish cyclist died in 100km road race. ioc took action, as first televised Olympics. athlete dying in front of ioc 1961 ioc mc 1964-72 testing for stimulants 1972 munich first serious case, us athlete ephedrine, controversial, still claims medal 1974 testing for AAS - tentative for 76 games in montreal 1983 IOC labs 1988 seoul -arne gave press  conference in rel to  johnson's positive. huge press. death of sport question. response was that this should be stopped. led to unified global effort. iron curtain drop changed this. 1999 ioc code, wada - changed med code into antidoping code 2004 wada code 2005 unesco convention

arne was olympian in1952 and nothing then,

doping code explanation

doping is definedas...

violation new 4. inadequate whereabouts information 8. administration, assisting, encouraging

prohibited list - wada publish each year

criteria - enhance, health risk, spirit of sport

(two of three)

doping need not be cheating to be banned

could say that any substance could be on list, and this is a legal prob

need common sense

substances w similar structures likewise banned, but legal difficulty to try

prohib method enhancement of oxygene trtansfer

distrib of substances 2004 - 36% anabolic 0.1% oxygen transfer enhancement

TUE

anti-doping strategy - info, educatioo, doping control,research

wada allocates 25-30% of budget to research vasst improvement since 2000

ioc never took this responsibility

strategy of doping controls - in comp - unanncounced out of comp - random - targeting (intelligence)

ME: what is current status of intelligence on gene doping?

need to improve intell

ME: how?

recent negative envts

- salt lake city experience, tendency  to make use of most recent advancements. 3 cross country skiers on aranesp - The Sweeney Experience' 2002: first reported that athletes had been contacting him to see how they could benefit; - The BALCO affair 2003; shows illegal production jsut for doping - The Athens experience 2004; first olympics at whch people banned for non-analytic positive; greek athletes; were using artif device for urine - Further designer drugs 2005; don catlin found further egs

The maked Machine false urine

REcent positive evens

SLC2002 -showed that we are close to athletes; these were subsrtances that had been on market for some months - Athens - pursued cheats successfully - WADA Code - UNESCO convention - Research fund - Proactive initiatives

whycontinue fight? - in ethics session. must be unbiased ME: this is too far. to pose all or nth is mistaken.

funl facts must be mentioned 1. no support for such an idea in t sports communioty - there was a debate. but it no longer exists. everyone agrees 2. wada andunesco convention, political estab has reinforced support 3. athletes themselves dont want it. athletes commisions are strongest

ME: when asking athletes about their feelings, hat do you think they are rejecting?

President of K: what are legal conseqs for med professionals?

AL: any person assisting may be banned. will not receive accreditation to be Olympic doctors. but we have limited legal action in civ law. at World Championships some years ago, some finnish professionals weree encouraging, investigation into law. found that action could not be taken. no legal ground .this changed the law.

The Irrefutable Success of Gene Transfer for Therapy of Human Disease) Concepts and techniques of gene therapy - applicationsv to doping in spoprt Ted Friedmann

give overview of underlying baasis of justif for potential of gene doping

rationale is direct outgrowth of gene therapy itself a controversial and difficult field

now a real area of cliincal research basis to think that direct attack can be and has been therapeutic

gene based doping - realstic poss imminent threat to sport - same pressure  that sustain drug doping  will lead to gene doping - based on advances in gene therapy

Evol and current state of gene therapy -controversial history - tools and concepts still immature - clinical reality, effective treatment, poss  cure -- serious risks, tolerable in context of therapy -- still subject to oversight and regulation

gene therapy for human genetic disease science, 1972, mar 3, 172, n 4205 friedman and robin

Proposal for human gene theerapy - needed - technically diffi -use disabled viruses as gene transfer vectors - many ethical and policy problems - reqs local and nationaal oversight - likely to be used for non-therapeuticapplics (enhnacmenet)

dark side broader than gene doping - enhancement of human traits in a eugenic sense.

LeRoy Walters, Kennedy Institute, Georgetown - somatic cell - germ cell

two major technical advances

recombinant DNA -cohen and boyer, 1973 - first efficient transfer tools (engineered viruses), 1981-1982; retrovirus vectors - Temin, Weinberg, Scolnick

retrovirus 1981-2 random integratioon, insertional mutagenesis adenovirus adeno-associate virus liposomes naked dna

ref: j biological chemistry; 1984, 25 12, 7842-9 - restored gene function and reversed phenotype

optimisms - beginnings of human clinical studies - 1989-90 - high expectations - exaggerated promises

gene transfer trials by year crash in 2000

ME: why? at the time of HGP completion

photo of jesse gellsinger

gene directly injected into liver

3 or 4 days later after injection, died react to vector not gene

Uni of Pennsylvania OTC study - a patient death -1999 - adenovirus vector to transfer ornithine transcarbamylase gene (OTTC) directly to liver - patient (JG) developed explosive

visible depression in Society of Gene Therapy

yet, heard of a diff technique

Paris study, Fischer, Great Ormond St LondonX- SCID

photo of Bubble Boy syndrome child - protect from inections

X-linked SCID,sevcombined immunodef dise - mutations in..

ex vivo study

introduiced to bone marrow cells

REF: NEJM article ,Fischer, Alain, lead Hacein-Bey-Abina, S -sustained correction of X-linked severe combined immuno

complete recovery - complete immunecorection 14 patients - some >6 yrs

but at high cost - 3 cases of T-cell leukemia -direct result of treatment - responsive to chemotherapy but reqd eventual one marrow transplantation - one death 2004

other two aree still alive and no evidence of residual disease. but diff to ustd

three cases of leukemia during effective treatment of x-scid deficiency

LMO2 oncogene has been disrupted - this is why we have leukemia

Why is this result imp? - proof - can be therapeutic - all previous studies ,potential or marginal benefits ,theoretical risks - no risk/benefit -X-SCID -quantifiable beenfits - gene transferrresearch becomes gene therapy - opens new era for med

legitmately therapy not just gene transfer

current successful therapies - X-SCID - q14 patients ,3 leuk, 1 death - ADA-SCID - 4 patients - prolonged - chronic grnaulomatous disease -2 patients

addl imminent and probable successes - cancer vaccines - introdcue genes (GM-CSF, CD40) to cancer cells to enhnace immune response (melanoma, CML, others) - restore tumour suppressor fn (p.53) - some photoreceptor degeneration andblindness -restored sight in blind dogs by gene transfer into retina - coronary artery disease

intra-tumoral...

CNS prophylaxis, new chemo agents

additional info into genome, which maintains mutant gene

now, te to fix defect - to change to wildtype gene from mutant

emerging tes - siRNA for gene modulation -especially for dominant diseasee - vector targeting -gene deliv - targetd gene modifi -zinc finger delivery of transcription factors ,transgenes

so, darker side -therapy is poss, what about enhnacement?

socially and ethically 'acceptable' enhnacement -we already do pharma, so why not gene - reelvant genes are becoming identified - tf, applic of gene tools to non-disease traits seem inevitable -

extension to sport - one of most imminent - unlikely to conform to standards of human clinical research -safety, informed voluntary consent

ME: why is informed vol consent unlikely?

sport or bioengineering? is it still sport?

ME: yes ,good photo, the q might be whether he would have been ahigh jumper if he had info about his genes

germ cell -therapy or enhance?

eugenics - old eugenics of late19th and early  20th C - new eugenics based on genetics - new potential for restrictive ,discrimintory

conclusions - all human gene transfer  -immature ,exptl clinical research, not standard of care -but if i had a child with X-SCID, i would opt for genetic approach - proven concept ,truly therapeutic - many dangers, known and unknown,reqs oversight

risks tolerable in light of disease ,but for healthypeople?

conclusion -sport may lead the way - opp to define social atts and responses

in US, not entertaining proposals for enhancement

discussion

how is read out monitored ?/ dosage? how follow efficacy of therapy? if so, might be poss to detect.

ME: what lev of cooperation is expected from biotech industry?

change position but

Goldspink Kathy Howe, killing off cells. factor 9 expt study shelved becuse of immune response to vector

holy grail is sequence correction

goldspink:

tom: surprised by one thing, which  was your optimism. I sat on FDA committe which looked at gene transfer when French study began.  what is your assessment of the science. is it  likely that LMO2 will not be repeated.

Ted: it hasnt in

Olivier: you refereed to over 700 studies, by RAC. do we have idea of success rate? are we aware of  some genes, neverr been poss to transfer. some genes more capable of expression than others. how long to go from animal model to human.

Ted: not all of 700 studies led to clinical. need to learn much more about how to turn genes on and off.

Olivier: side effects?

Ted: dont see them until you see effect.

Olivier: procedure itself not harmful?

Ted: in Gelsinger it did. will not see ath going wrong until see sth happening

Q: state for muscular.

Q: leukemia. single gene as key factor .also v shiort period - 3-4 years. usually cancer 10yrs. sth peculiar of case , it is activation of agene. are ways to avoid activation.

Ted: but not activitation, but disruption

Q: 3rd case special since dif

Odile: transgene role is enormous. cannot claim thatt there are no te that could counteract potential activations.

Chair: what is view on detection of gene transfer? willl this stop? or need legislation on other level?

Ted: no, wont be enough ,but will be strong deterrent.

Effects on organ systems/tissues

Heart -    bigger, greater stroke vol -    inc maximal cardiac output

Blood vessel (heart and trained skel musc) -    more capillaries -    improved dilatory capacity

Blood -    ic total amount of red blood cells -    evevn larger expansion of plsma vol, reduced blood count in a blood sample

Adipose tissue -    reduced amount

Connective tissue/bone cartilage -    inc amount/strengthened

efects on organs systs

endocrine system -    insulin sensitivity -    catecholamine and gH response to ex

skin

imune systt

lungs

nervous system/brain -    inc capillaries more utilised

what factors influe performance

bouchard, C. et al 2005 -    gene map -    summarise what has happened in last year -    prediction of health or fitness -    no agreement yet on ‘key genes’ using popn genetics -    difficult to validate – separate population studies reqd

how study human muscle ‘phenotype’? -    skeletal muscle. -    How dna, to mRNA to protein -    Strength and endurance mapped to samples

Considerations -    species -    type/duration/intensity of intervention o    aerobic, resistance, inactivityy -    acute or repeated -    sampling site and time(s) -    amount needed -    mRNA and/or protein -    localisation -    housekeeping genes/normalization procedures o    complicates, regulation -    method – broad or narrow?

ReF: fluck et al 2005,

REF: Mahoney FASEBJ 2005 -    after acute ex, more genes activated in sets -    limited by number of biopsies you can take. Scientists would ilke one every hour -    but used 3h and 48hr

Generating a human endurance ‘transcriptome’ -    24 sedentar subjects -    240 musc biopsies -    24hr post ex -    measured phenotypic by important

500 genes ‘activated’ by ex in humans - COL3A1, FABP4, IGF-1, TGFBR2

what prdicts for improved cycle performance following 6 weeks training?

What genes regulate -    better oxy deliv

Timmons et al FASEB K, 2005

Gene ontology analysis

PGC-1 inc by training in following hours

Ameln et al FASEBJ 2005 -    HIF-1 drives expresion of epo. -    And VEGF -    At protein levvel, was regulated by acute ex, bound more to Dna, drives target genes,

Does epo play role in muscle? -    perhaps, protective or androgenic -    thus, epo might have systemic and local eeffects beneficial for performance

receptors of VEGF go up – inc to manipulate receptor side

5wks of training, VEGF goes up

to develop gene therapy fully, must understand cocktail of things that are going on

in gene therapy, CV side things are going on, but must know more to grow complex structues such as vessels

Targets of interest at geen level -    transcription factors, angiogenic, mit biogenesis, hypertrophyt

cell doping -    naked cells -    encapsulated – put into tissue, then remove. – safe for cheater, since no trace. Can be done with epo and inserted anywhere. -    sooner than one might expect. As many cell trials. And move towards gene modified cells. -    Yesterday, venture capitalist in san diego, using fibroblaysts, for parkinsons

Questions and Answers

Question: focused on up regulation, but what was freq v down reg

A: usually more up regulated, but perhaps a quarter, 3-4times more up than down

Question: how do trained, elite athletes differ?

A: some surprising, some expected. Not easy to predict.

Question: can distinguish

A: no of subjects needed to study polymorphisms v high, often differe considerably. W n24, impossible

Question: important?

A: extremely. But every thousand base is … bypassed polymorphy by looking at integrated response

Question: study in male, not female? Same for female? Each react differently to training

A: what would you expect?

REsponse:

Response: total of 16mins, can dramatically inc endurance performance, no gender related differences. Might depend on ex mode.

Olivier: concern of cell therpay, problem earlier than gene doping. Today, company proposing use of tendon cells to strengthen repair of horses. So is coming at commercial level soon. One key element in detection is time window we have. You have observed some transformation at mRNA level. What is order of magnitude of change?  Concern that signature will be lost.

A: presume that gene copying intensively is more stable and chronic than when you train. I would guess there is an elevation of gene doping product.

Olivier: what level should we detect?

A: problem is legal. Ban people that have strange pattern? Cell therapy been around for long while. Blood transfusion for over 100yrs. Bone marrow transplant since 70s, skin transplant, etc. cell therpay not new, but gene modified cells is novel and cells that are hidden.

Olivier: cells that grown and reinjected

A: yes, like cell

Chair: Odile Cohen-Hagenauer

Vectors and Delivery Methods C. I Edvard Smith, Karolinska

Gene therapy -    gene could be 10,000 base pairs -    virus contains maybe 3,000 base pairs -    human genome, thousand books with thousand pages

today, cannot fix gene, but put in an extra one

concept oif a gene

if cell goes through many divisions and gene is in episome, will be lost. So if need to put in cells that divide many times must go for integration. Only way to ascertaint hat will be in cell.

Problem with going from outside of cell to nucleus

Local and systemic gene therapy

Gene transfer techniques -    non-biol methods (plamids, oligonueclotides) o    liposomes and polycations (lipofections) o    electroporation o    in situ naked dna injection o    gene gun (biolistics) -    biol methods o    transduction (virus-mediated transfer, most efficient)

drawbacks to viruses

DNA complexes – plasmids or oligonucleotides -    insert size no limit (can use long stretch of DNA, makes possible sequences, marker of normal) -    episomal – normally this; outside chromosome -    short-term expression -    broad host range -    unstable in vivo

is possible to remove all foreign elements. Ie design genes that do not carry any foreign elements, so  harder to trace

Virus as a vector for therapeutic genes, eg hiv

How use a virus?

Concept: the packaging cell line

IMAGE

Empty particles – allow introduction

Packing cell line 2nd generation

There are a number of viruses that can be used -    ecah has benefits and drawbacks

Concept: RNAi – how does it work?

IMAGE

Recent phenomenon, a decade, first observed in plants. If introduce double stranded rna has different features

In mammalian cells, if, instead of long dsRNA sequence, use short siRNA molecule, can have same effect. Si = short interferring

Regulates gene expression

Can achieve stable expression – deliver shRNA

Vectors contain unique sequences that can be trace Provided you know where and how to look Apart from t vectors there are their products

Questions and Answers

A: when expresss siRNA, is v short.

Question: if do cell culture, get up to 10,000 fold interference.

Question: will day come when can do entirely in vitro?

A: yes, should be. But viruses also have problems. They rely on cellular machinary, so good but also limitations – must use normal process of making proteins. If do invitro can avoid regulatory problems.

Vectors and delivery methods – vector and transgene vector detection H. Haisma

www.rug.nl/farmacie/tgm

in non-viral vectors, mostly have much chemical stuff added to them to allow entry to cell

adenovirus

shedding data, gene therapy stdies

shedding

excreta – semen, stool, saliva, urine, blood germ line – sperm, ovum

environmnent – next of kin

if people treated with gene therapy, can find vectors in almost any of tissues

do not find anything in germ line - ie no transfer to next generation

Gene doping detection

IMAGE OF TABLE

Dna – muscle – no shedding - months For adenovirus, shed in serum, saliva and urine, but only last days AAV – muscle – serum saliva urine – weeks Retrovirus – iv blood – semen (probably through prostate) – weeks

Vector: -    protein – no, requires biopsy -    dna, rna – yes, blood, urine -    chemicals – no, requires biopsy -    antibody response – yes, blood

clearance of free dna IMAGE OF GRAPHS

Even if inject into muscle and leaks into circulation, no way of finding. -    goes to liver and is broken down – perhaps find 10% of it in blood, after 30mins

dna detection?

Baterial is immunogenic

CpG dna: -    unmethylated CpG motifs are abundant in bacterial DNA -    the frequency of t CpG motif is supporess and highly methylated in mammalian DNA

detection?

Transgene -    protein o    human original, yes, elevated blood, urine o    new modified, yes if in blood, urine o    human modified, yes if in blood urine -    effect – yes, if in blood, urine

use effect as most promising

specific detection?

IMAGE

Isoelectric patterns of epo

REF: Lasne F et al Mol Ther 2004, 10:409-10 -    can see difference in number of glucose; same gene, same protein looks different from muscle or kidney -    possible fror detection

detection?

Specific – every potential drug needsa  specific sampling and analysis method – also detect other doping General – profiling allows t determination of (major) changes in gene expresion pattens by: gene array or proteomics

Genetic interventions IMAGE

Serum Protein Pattern diagnostics IMAGE

DETECT MAJOR CHANGE

Proteomics IMAGE

Gene expression profiles

IMAGE

Alreay used for cancer patients -    sample from tumour, isolate its rna, then matched on a chip, comparative analysis from arrays -    in sport, chip would convey change, 25,000 patterns on chip

Gene Array

IMAGE OF CHIP

Discussion -    gene doping vectors will be undetectable -    proteomics and gene expression profiling are powerful generally applicable methods and will be part of diagnosis and therapy in t future -    requires fresh tissue, urine or blood sample of good (RNA or protein) quality -    logistic (handlig, storage) -    global change in sampling handling is needed

Questions and Answers

A: once gene is active, no way of shutting it down.

Chair: Problem, because need 100% proof to commit someone

Mainly deal with EPO

What matters, detection of EPO or that carry more level of EPO than rules permit? -    v costful

do you want to detect exogenous and transgeneand rEPO, or have world athlete not go beyond a certain threshold

Epo gene transfer -    can easily be monitored in vivo (hematocrit) – as hematocrit will just increase -    not supposed to induce an immune reaction -    therapeutic indications: epo sensitive anemias, eg chronic renal failure

epo gene transfer 1.    state of t art of vector systems 2.    regulatable expression – pharmacological control 3.    adverse effects – alluded to by haisma 4.    detection of abuse and gene doping

state of art of vector stys

state of art of vector systs 1.    dna electroctransfer of plasmid dna in rate muscle- just need needle, introduce gene in muscle, then electric field and dna will stay in. 2.    polymer encapsulation of xenogrenic or allogenicc fibroblasts or myoblsasts engineered to secrete epo 3.    sub-cutaneous implantation of microdermis biopump 4.    IM injection of epo-recombinnt AAV

Gene doping and the regulation of skeletal muscle hypertrophy Lee Sweeney

Skeletal muscle

Gene delivery into muscle -    primary targets are post-mitotic (non-dividing) nuclei of mature muscle fibers -    gene delivery vectors o    naked (plasmid) o    virus •    aav serotypes 6 and 8 are most efficient •    capsule modified lentiviruses o    non-viral dna conjugates o    adult stem cells •    muscle and bone marrow derived

adeno-assoviated virus mediateed gene transfer -    readily infects skel musc -    accommodates <4.7kb synthetic gene -    delayed onset of expression (Biut self compleent and high titrs decreates) -    no viral gene expressio -    no immune response in mice /capsid immune response in larger animals -    no integration (?) into post-mitotic nuclei – better for FDA safety -    long duration of xpression (likel years to decades) – but depends on usage, since only hitting postmitotic. Eg. Normal sedentary mouse loses no expression, but if hypertrophy, then lose in matter of months o    in monkeys that are not exercising, expression remains

efficiency of aav gene transfer -    50-95% of fibers show expression of reporter gene (LacZ) delivered by AAV1 -    transduction of -200% of all muscle in mouse possible w high levels -    looks possible for dogs now.

So, enhancement?....

potential appliocs for sskel musc -    primary musc diseases, duchenne beckeer, muscl dyst -    loss of muscle function during aging -    secration of therpaeutic proteins into t blood (factor 9 for haemophilia)

loss of muscle function during aging (sarcopenia) -    progressive loss of muscle mass and force beginning in fourth decade of life -    slowed, but not prevented by exerccise -    negatively impats health and quality of life -    occurs in all mammals -    may be due to progressive failure of skel musc to repair damage (decline in regenerative capacity) o    prob with ageing when satellite cell fusion doesn’t occur as well

Muscle Growth and regeneration. -    Various growth factors, HGF (hamatocrit) -    IGF-1 one of key factors – imp property (most inhibit maturation of muscle cells, so if over express, would inhibit muscile) but igf-1 drives proliferation, then XXXX

IGF-1 -    drieves protein synth -    reduces protein degred -    stimulates sat cell different

GH-IGF-1 axis - local synthesis decreases with ageing

Will inc IGFF-1 expression im muscl promote growth and refgernation pathways?

IGF-1 expression targetd to muscle -    utilize aav to achieve efficient skel musc delivery -    utilize musc specific promoter (MLC1/3) to limit expression to skel -    igf-1 over exzpresiosn should promote growh -    injected legs did not have age related loss -    also stopped loss of power

hyp -    igf1 overexpres should promote musc growth ad repair leading to t following outcomes

IGF-1

Conclusions – -    igf1 ocer express prevents age-relationship atrophy and loss of skel musc function -    skel musc regen i\

20% or more depending

prevented fibrosis due to severe injury

would it lead to enhanceemnt for athletes? If combined w trainig?

IMAGES

Igf-1 effect local- -    avoids harmful side effects, since blood levels of igf-1 not eleveanted -    decteion difi or impossible without biopsy, unless surrogate markers. -    But difficult to seee surrogate

Could systematic delivery of any ageny provide a similar effect to that achieved w local prodn of igf-1?

-    a TF-beta family membner, myostain antagonise igf-1 action, limiting skeltal musc growht. With igf-1 trying to create a balance. So knock down myostat to create effect on igf-1 -    possible cardiac toxicity -    relatively speciic to skeletal musc -    decreases fat -    loss or inhjib or myostat inc musc mass -    wyeth is in phase 2 clin trials w anti-myosttin antibodies for multiple types of muscle dystrophy – scarey note: all have dlated cardiomyopathy – could exacerbate cardiac condition, but speculative at this stage. Beginning to see effects. In obse patient, marked decrease in fat

Muscle growth and regen -    would inhibit prolif of sat cells, igf inrceases

myostatin inhib could allow systemic delivery -    antimyostat antibody injections into t blood of mice result in muscle hypertrophy -    viral delivery to liver or peripheral skel musc could generate screaion of anti-myostatin inhib in blood o    could look in blood for trace -    should result in inc growth and repair -    not clear if harmful side effects. Not clear would prov all benefits of igf-1 especially during senesence

gene doping could be detected by screening

myostatin KO Mouse -    wild type v myostatin null -    in any athlete, would not want total knock out

belgian bull

young child -    parents, mother is competitive athlete

conclusion -    gene transfer could be used for skel musc

nuber of properties could be changed -    strength, but repair, better muscle mass, strength and speed, maintainence of mass and strangth during disue, inc endurance

is genetic enhancement going to be a reality? -    inevitable -    banned on safety and fairness o    but safety sufficient -    if used in widespread for preventing aging, then harder to ban in athletic population. Especially when earlier better for intervention. -    Genetic profiling of athletes ‘ raise issues of genetic ‘fairness’ -  If someone has genetically decreawed myostatin, then is also unfair

Where are we now? -    can do this today o    naked dna o    direct injection o    vasula injection o    regulated gene expression

acknowledgement -    elizaeth barton, linda morris, rosenthal, farrar

Questions and Answers

Question: these are small animals. But how many injections for thigh muscle of human?

A: we are moving away from injection, rather vascular delivery. But problem is immune response in vector

Questions and Answers

Tom: difference of view about what happens to myostatin knockout. Does it give strenght or not?

A: JHU argue that 17% increase in Arnold Schwarzenegger mice. Not a good balance in extra weight.

Lee: agree, if knockout altogether then not much strength .

Odile: but mujst increase other body parts

Lee: bones do compensate, do get larger. But not looked at tendons. But would assume they would hypertrophy as well

Geoff: myostatin KO; if keep putting into req state, can activtate w mgf, but if keep knocking out myostatin, energy pool diminishes over time. Athletes might use on short term, .

Lee: child born with KO liely to have problems, but mother doesn’t.

Question: shown that athletes using steroids get inc in sat cells, so can detect by muscle biopsy.

Geoff: butler brown in paris when taking biopsy from steroid using athletes, telelle length – life of sat cells – diminished – whereaas we might live to 180 efore run out of sat cells, athletes and exessive exercise might run out

PPAR and the creation of the Marathon Mouse Ronald M. Evans, Salk Institute

What are they? -    peroxisome proliferator-activator receptors, comprise set of three related nuclear hormone receptors, that control broad aspects of lipid metabolism -    expresed in different tissues and are naturally activated

Fat storage and burning -    determined by relative levels of ppars,

revving up metabolism -    synthetic ligand GW1516

created marathon mouse (ppar)

transgenic mouse -    now expresses ppar-delta

muscling in on endurance -    will also treat wildtype (ie. Normal) littermates w orally active PPARd specific rdug

red muscle increased transgenic mice -    pink – glycolytpic fast twitch type ii -    - suggest switch to type 1 myosin rich fibres (slow twitch) -    from carbo burning to fat burning

A – better B – worse C – same

?

treadmill challenge

improved exercise performance in transgenic mice -    80% more time and distance capacity what about ppard null mice? -    Total running time only 20min, compared to wildtype of over 1hr and transgenic of more than 2hrs

Under study – does GW1516 enhance performance in mice?

Future – magic pill?

Clinical -    muscle wasting -    weight loss mec related to inc oxidative meabolism

opp for abuse -    inquiries from athletes, coaches, a horse trainer

conclusions -    ppar-delta directed metabolic changes produces a mouse w a long distance running phenotype -    possible to alter single component of compplex system –ie muscle fiber en burning ) to enttrain t rest of physiologic network -    genetically produced ‘delta’ muscle fibers confer high performance even in absence of exercise (training) -    exercise physiology can be predictively manipulated -    ppar-delter receptor

Inflammation/arthiritis – phase I

And repair of: Bone Cartilage Ligament and tendon

Arthiritis is chronic, requiring long term gene expression, the other 3 are not – repair, then stop

Gene tansfer to the synovial fluid of joint

ex vivo and in vivo

Some success with ex-vivo

ex-vivo preclinical -    safe feasible in rabbits, rats, dogs, mice horses -    levels of expresion sufficient to inhiit animal models of RA

use retrovirus

phase 1 study in knuckle joint w rhumatoid arthiritis

put into joints that were due for removal

PAHSE I RA STUDY conclusion  (N=2) -    gene transfer to human joints is safe and feaible -    intra-articular gene expresion occurs -    patients accept procedure well -    reported relief, but not fully documented -    phase II studies merited    , BUT which vector

not progressed due to lack of funding. Big pharma wont touch it, small biotech don’t have enough money, millions just to treat small number f patients, but made progress by going around with it.

Absent from horse who recent therapy

Now bone

Direct injection of adenovirus – BMP-2

V responsive to gene transfer

Do this by making hole in animal’s bone and intro virus (BMP-2)

Rate undergo surgery, where femur exposed and external XX attached 5mm defect in femur would not heal if now use adenovirus and inject 40micro ltirs

after 8 weeks,good healing

Wolf’s law – how bone responds to load

After pins removed normal mineral content returns

Effectively repairing bone that would otherwise not occur

Concluding that we can do this

Cartilage

No intrinsic ability to heal

If partial injury to articular cartilage will not repair

If goes through to bone bone marrow defect

Trying to take adv of fact

Use with rabbit

ligament and tendon -    healing initiated by forming of blood clot -    gene transfer to healing ligament

Indication – status – relevance to doping Inflam/arthiritus – phase1 clinical – high Bone – advanced preclin - ? Cartilage – preclin - ? Tendon/ligament – experimental – high tendon-muscle

If uses it when injured, then goes back to track, is horse doping?

Overlap between legit medical use – do have arthiritis – but overlaps with doping, since reason for arthiritis is due to over-traiing, so we increae their ability to train

Questions and Answers

Arne: Different between doping and treatment is already in use as TUE. Sports peple should be able to benefit. Problem is when it may go beyond.

Chair: Friedmann Standard in medical doping involves looking for assays

Don’t worry about looking for epo if you are interested in finding it

Look for local effects Systemic Homeostatic

Need un-biased global assays Changes in gene expression patterns in distal non-target tissues

WADA Perspectives on Gene Doping in Sport Olivier Rabin

Anti-doping analyses started in 60s based on detection of drugs in urine (stimulants and anabolic steroids) Progressive incorporation of -    immunassays: hcG (1987); LH (1997); hGh (2004) -    electrophoresis/focusing: EPO (2000); HBOCs (2004) – human blood oxygen carriers -    flow cytometry: blood transfusions in 2004 trend evolving from pure chemical analysis to incorporate more biochemistry and biology

evolution of rules -    from imperative need to detect and characterize t doping substance(s) in athlete’s biol specimen -    to -    possibiilty to use markers of abuse of substances to report doping -    as long as scientifically validated (concept and method)

markers approach already in final development phase for hGh detection: -    IGF-1 (liver) -    P-III-P (bone) Abnormal markers variation are used to qualify doping Hwr, almost 10 yrs of research and more than $4m

Fundamental concept

Abuse: substance – extra gene -    non physiological modification (imbalance) – change in homeostasis -    detection: where to look? o    Genomic o    Transcriptomic o    Proteomic o    Meabonomic

What to look for? -    signatures of changes unique to doping classes of substances

cannot say one substance equals one specific signature, but can make claims about relationships

limits in -    interpretation of gene modifications -    protein and peptide knowledge -    interpretation of metabolic changes

some gene regulations not fully understood

where to look? -    accessible cells or biol fluids w minimal invasiveness (urine? Blood cell lines, buccal cells; ) -    imaging (changes, markers, radiolabeled tracers)

challenges faced -    identification of right target: where, what how, interpret? -    Accessibility to measurable modifications (invasiveness, time window, ethical methods) -    Eliminate other explanations than doping (gender, age, diseases, enviro, ethnicity) -    Development of specific tools for anti-doping -    Extremely sophisticated constructs w fine modulation already in animal models -    Approaches may well work for gene doping or some substances, but what about cell therapy, in partic autoloous cell transplants – eg. Tendon strengthening in horses – extremely difficult to monitor. Looking for same cells in same organ. Already in application -    Costs. o    Money we can invest has limits. o    Also limit of cost we can ask for analysis. -    Layman accessible! – particularly lawyers.

Hope -    epo study in monkey showed genetically transferred epo still detectable o    not endog -    microarrays and SAGE appear to reveal target genes or mRNA. Proteins are promising. Metabonomics will grow. -    Combination of discriminant factors o    Projects ongoing on physiological markers that can be followed by biochem o    Have longitudinal XXX of athletes and detect unusual variations o    Doubt in future that can test every athlete for gene doping. Must start

Pragmatism -    science is likely to deeliver the antidote. When and how? -    Resources can be v demanding on anti-doping and beyond capability. Need to partner. -    Anti-doping market is limited. -    Partner with academic or private org -    Hope for some large scope methods, not too narrow in application -    Even if gene doping applied, limited chance of success, delay in significance impact in sport, though success will come…

Difficulties, always new pharma drugs

Current methods cannot detect gene therapy

But if devevlop, perhaps could apply to other things, proteins/peptides, etc

Gene therapy to gene doping -    non-therapeutic use of genes, genet elements, and/or cells that have capacity to enhance -    muscular, anaemia, pain relief

Screening a worry

Matt

T culture of sport Natural talent and effort Natural variation of talent is intrinsic to sport – if your body doesn’t fit, then do something else

New types of sport have developed that appreciate natural talents – where certain body types suit

Equal opportunities -    not part of culture of sport

cannot complain that

does not imply that sport activity is result of genetic lottery -    there is no genetic lottery, but evolution of natural talent combined with effort

fair chance – if different heights where height is relevant, then is unfair – so we divide in groups -    age differences, sex

limits of accessibility on fair innings argument

need sufficient number of competitors to make it worthwhile

natural variation –s mostly self-regulation

people w extreme gene mutations not become elite athletes

limits of genetic screening

gene doping for improvement talent and level of effort -    opening for fair innings – set up games where GM athletes complete, but should we?

The phenotype routlette -    natural phenotype is t result of a delicate balance in order to master o    genetic program o    epigenetic instabilities o    biological chance o    environmental challenges

for safety reasons -    major reason against -    keepin athletes healthy is difficult enough at such extremes of performance. With gene doping more complicated -    delivery, expression and safety -    protect athletes from their own winner instincts -    protect next generation from manipulating their health -    health expenss for sports moveement will likely sky rocket

if we assume safety? -    natural mutations have many advantages appreciated and accepted -    some can be screened for -    hwe, where draw line, w gene doping, one has to screeen for many genetic variants in order to meet t same requirement

snowballing inflation -

rules of fair play -    sport activities presume a pre-competition agreement about rules -    winning is essnetial but so is also fair play

fairness as equal opp not part of sport

as fair share of innings – part of sport with rough measures

as fair play – intrinsic

protecting privacy -    can we protect, with testing -    it can, if understand what privacy is all about -    often willing to give up privacy in certain conditions o    enjoying sport activities is one of those conditions

gene testing – includeed in rules of fair play -    accepted part of different practices -    research, medical treatment, sport activities -    need to regulate. How reliable? Who has access? How handle safely

yes to gene technology -    no to gene doping is consistent w a yes to medical treamtnet

aging of muscles problem – fear that cannot set limits -    distinc between gene transfer in care of patient, always balancing – benefits v risk -    patients are closely mointored to correct for unforeseen -    v different thing to do this on healthy people, where not monitoring closely

these questions not new, many drugs that used on old people that we would not use on younger

eg. Morphine good for people at end state, does not mean that give to anyone in pain

ethics and t challenge of t potential use of genetic technology in sport. Angela Schneider

Summary of effort, talent and fair play -    sport is rule governed -    action against rule is cheating -    should thre be a rule against – yes -    hwr, important practical and ethical problems

Winning the genetic lottery -    is it fair to compensate for those who have lost t genetic lottery from a sport perspective but still wish to compete in elite sport by enhazncing -    Hannson ‘why not allow gene doping’

Need to answer some important concepts

Contested distinctions -    natural and unnatural (artif) -    point of sport is to measure difference o    we have allow naturally differences to affect outcomes o    hwe, we wil not allow t potentially fairere gnetic equalization that would occur through enhancement. Do we have good grounds?

Ethical foundation -    preventing avoidable harm -    paternalism -    performance enhancement -    vision of sport and how gene doping fits within this context -    sport for humans not humans fro sport -    contested

do not design humans for sport

ME: but we do

Sport exhibits values -    leadership must choose which values -    eg. Equity of access; implications of genet therapy for those who currently live with disease or disability; specific sport oriented issues

Laser eye surgery -    language is intructive – if describe as removing normal variation, status as enhancement clear. But if removing abnormalities, more like correction

LASIK -    used in some sports. Should it be? -    Enhances

Comparison w rules against doping -    one point of rules is to limit risk -    risk of laser eye, 5-10%, possible risk -    how much risk is too much? -    Not clear why sport should accept any degre of risk for beyond performance – ie enhancement -    Most relevant value is definition of health

Consistency and credibility of rules In anti-doping have analogous substances

Principle at stake

Distinction between enhancement and repair -    restorative and addtive distinction (fost)

repair is unprobc

incidental improvement -    Tommy John elbow injjury – generalyl accepted

Surgery in absense of defect is enhancement

But Tiger Woods – laser eye

Laser correction public use now

Not like cheating in way that steroid use is

Practice doesn’t cause sufficient harm But this sets bar high

Things that are acceptable elsewhere, not aceptable elsewhere

What do with grey zones? -    arbitrary, but

with strict liability

privacy issues and access to genetic information -    genetic information especially private -    indicative of identities in special way -    puzzle – genetic make up not indicative

social question -    maintaining privacy of personal genetic information  vs potential role of sport community becoming wedge used to derive greater geneal

wituhout moral support, sport will not be able to preserve humanizing influecnce s if sport recognises and re

genetic modification and improving humans -    enhancement

Sport is leading by saying we will regulate

Ethics, enhancement and sport Tom Murray

Meaning of soprt as a human activity: why the world loves the olympic games

Excellence in sport as expression of -    natural talents -    virtuous perfection of those talents

Aristotle – eudamonia -    full good natual ilfe

there are unvirtuous ways of getting these

objections to doping control in sport -    claim of incoherency -    line drawing problem -    resistance Is futile -    appeal to individual liberty -    romantic/promethean view

ME: but this ignores game theory. It’s not about the rules. It’s about the intended test.

incoherency claim -    no cnpcetual ethical or practical distinction among different means of enhancement sport performance o    the marathoner’s shoes

response -    hypothetical

Line Drawing problem -    all possible lines are arbitary -    aribtrariness is fatal flaw

conflates two meaning of arbitrary -    as unprincipled, indefensible -    as reasonable response when o    drawing SOME line is defensible o    placing line IN THIS PLACE likewise

athletic virtues – fast.

Why 5 players Why not 50 players, look like rugby -    ME: not really. Dimensions of playing field,

But this would not have any of the characteristics of bball

Why draw in this place? -    why not 6 in team? Or 4? No 1 on 1

would not have a game of bball

ME: tom is not distinguishing different kinds of rules – he is talking about constitute rules, not regulative rules

Resistance is Futile -    not a first-order ethical claim -    primarily two empirical predictions o    control will be impossible o    bad conseques ensue -    control is never perfect -    depends upon o    public consensus o    effetive enforcement

ME: he is now switching to regulative rules

ME: breaking some rules is not bad in intelf

there are silly rules – prohibition in us

So must have a public consensus in support of rules

In sport, if ban certain things but do not enfocre

Argument from Individual Liberty

Presumption in favour of liberty Paternalism difficult to defend w adult athletes Hasting Center project -    coercive impact of drugs in sport: the unlevel field

doping control done well provides level playing field

argument from liberty fails to

romantic/promethean view -    humans as self-creators -    understand cultural and philosophical context and implications -    valorizes unfettered will and self-manipulation -    relation to human flourishing? -    Case of anorexia o    ‘anorexia is t cultivation of a specific image as an image – it is purely artficial rceation and that is why it is so admired. Will alone produces it and maintains against considerable odds’ noelle casky, 2003, 129

Triump of Performance Principle -    max performance by any means at any cost -    power lifting: drug free and? -    Unavoidable conseq of refusing to set limits o    Greatly increased risk    rules governing a practice not equal indefensible parternalism -    Threat to spirit of sport

No longer throw people to lions

ME: so the level of risk in sports is just right?

Ethics of enhancement in context -    non-trembling neurosurgeon -    point of practice: spirit of sport -    not t means per se, rather their relationship to t goals of t practice, values and human flourishing

imagine drug with no side effect

imagine drug diminishes hand tremour and neurosurgeons see benefit

let’s also assume that mperson you love most in world needs operation

2 surgeons, one says biomedical enhancement always ethically wrong, never use tremour reducing, and second says, I use it all the time

you would choose one w best results

first surgeon missed practice of surgery

point of sport is natural excellence

point of surgery is to make well

different kinds of human activity calls for different kinds of rules -    partic to circum of relevance

not bad to prevent muscle wasting , but still suspect as use in sport

because of goals and values of practice

challenge of genetic enhancement in sport

what do we value in sport? -    natural talents -    virtuous perfection of talents

what do we disvlaue -    distortion of relationship between natural talent, virtue

what makes a talent natural?

Complex phenotypes -    genome as ecosyst o    genes interact complexly w each other genes, w external environment -    genetic difference in general not rigidly determinative for human behaviour o    see behavioural genetics report at hastings center website

child who has been engineered prenatally, natural?

ME: ecosyst argument – just a complexity argument?

Differences in natural talents? -    as vicious inequalities to be redressed? 1.    Vonnegut’s ‘handicapper general’ •    Disable smart -    As expression of human of human variaton to be celebrated? -    Olympic movement opts for t latter? 1.    Alternative romantic/promtehan, triumph of performance principle

Fairness – but is life fair?

Sport is arbitrary in some ways

Can this be accepted?

Look at high-jumpers

Achilles tendon most fragile for fosbury

If in 10-15yrs, cell therapy to heal tendon and grow by 10% more and allow better training, forbid? – yes it should, but I need advice.

Paternalism -    we cannot have been told to decide for -    gov put strong warnings on sale of tobacco. But athletes do not know what is dangerous for their health.

Basis of beliefs

850million people practcising sport, 750million recreational

every recreational is competing with self

only 150million in sports contest

we believe that this pyramid provides great educational tool, for body and mind

sport taches social sskills- achieve more in a team, than alone

respct sport, respect society

sport integrates

sport brings health

sport shapes identity

we know life and soc is unfair, but social value of hierarchy – doping destroys ranking system

we believe that protect health, even if paternalism

believe in one example – that fight against doping is important for keeping explemar of sport

different between nature and nurture -    virtuous perfection is essence of sport -    everyone wants to reach limits – leaves sense of accomplishment -    important anser against existential fear that everyone has – who am i?

recruitment -    social aspect -    champion is admired -    not everyone born with talents, but way athlete behaves and lead life is important to protect. Genetic doping would destroy

doping rules are imperect

compensation theory -    compensate up to normal level, but then are cheating, but allowing less effort athlete to be compensated, then penalising the champion

my plea is please give us clear rules – must be crystal clear

enhancement not be allowed

where draw line must be done with ethicists and scientists

Stockholm Declaration Arne Ljungqvist

Composed of olivier, ted, and arne

Today, several human genetic diseaes can be succesffuly reated by gene transfer Gene transfer is still a very immature and it is still an exptl field of human medicine

Challenge?

Change serveal to  ‘a few’

Extensive and rigorous regulatory mechanisms need to ensure safety of research subjects and patients

Gene transfer procedures must -    follow code and principles of human exptn and clinical research -    be performed strictly in accord w local and national rules and regulations for gene transfer in clinical research

Comment: these are more general reseacrh

Tom: human beings?

Lee: clinical trials

Tom: clinical research aimed at dealing with human disease, but some of this will not be about disease. ‘Follow codes and principals governing research to human subjects’

Matt: follows nuremberg, etc

Tom: these are minimal conditions, we can elaborate

Lack of compliane w standards an rules of gene trasnfer procedures must be considered as medical malpractice and/or professional mis-conduct

Development appropriate sanction mechanism for illegal application of gene transfer in sport

Gary: who will develop?

Comment: since no legal, ma

Maybe unethical or illicit

Illegal implies court of law

Unethical and/or illegal

Promote public discussion issues on THE PROSPECT OF gene based enhancement and develop education progrms

Be developed

Comment: this implies it exists

Olivier: can argue this in animal models

Odiele: reservations, since education can be spreading

scientficic progress made through resarch projects supported by WADA and others suggest that new detecion and screening methods are likely to emerge in t near future, which will help to keep sport untainted by gene based doping methods

Cell doping? It is covered if we move entirely towards gene.

Delete ‘near’?

Lee: must emphasise need for research

Support research programs instituted by WADA and other anti-doping organizations

Comment: ‘should be supported’ at end remove support

academic and private research organizations to dedicate resources to further progress in gene doping research should be encouraged

Larry: deter, not just detect – progress to ‘deter’ gene doping

Academic, government and private research

Genetic and denomic charcaterisation of athletes to determine genetic traits is contrary to the principles of sport

Rogge: contradiction with screening

Odiele: when speak of genetic trait, must speak of interited trait

Dave: might be reasons to screen for genetic traits in medicine

Tom: say something about unwise nature, but not sure contrary to principles of sport. Not because against principle of sport, but because of potential harm

Lee: must specify athletic traits, not genetic

Ted: not determination of trait, but use of it to exclude. Ie. To determine eligibility

Peter Fricker: this research has been done. Issue here is about discrimination. Need to look at genes and risk of illness.

Tom: use of genetic information about putative athletic ability to discriminate against athlete, should be strongly discouraged.

Add to ‘select’ or discriminate

Peter: must allow ethical reseearch must proceed to validate role of genetic information

Enhance awareness of potentiall illicit use of gene transfer techniques in sport

Promote knowledge on medical and physical dangers associated with gene doping

Odiele: woiuld we like to put forward idea that there are dangers?

Olivier: dangers alone?

Odiele: why not ‘misuse of gene transfer’

Olivier: risks or dangers?

How about potential risks?

ME: why not inter-governmental rules and regulations? As well as local and national
