Biopharming and Beyond

GMOs on Steroids

Martin Donohoe

Biopharming

The engineering of plants to produce pharmaceuticals such as enzymes, antibiotics, contraceptives, abortifacients, antibodies, chemotherapeutic agents, other medications, vaccines, and industrial and research chemicals

Biopharming

Rationale:

Farmers/farms cheaper than technicians/manufacturing plants

Seeds/silos may be cheap storage system

?Cheaper drugs? – doubtful given history of pharmaceutical industry pricing patterns; also, multiple externalized costs

Approximately 400 field tests worldwide since 1991 (over 100 in

U.S.)

Top 12 Biopharm States

1 – Nebraska

2 – Hawaii

3 - Puerto Rico

4 – Wisconsin

5 – Iowa

6 – Kentucky

7 – California

8 – Texas

9 – Florida

10 – Washington

11 – North Carolina

12 - Maryland

Biopharming

More than 15 companies involved in US (75 companies worldwide)

USDA conceals crop locations from public and neighboring farmers, in most cases hides identity of drug or chemical being tested, citing trade secrets

Even state agriculture regulators often unaware of info re drug or chemical involved

Grocery Manufacturers of America

National Food Processors Association

Organic Consumers Association

Friends of the Earth

Others

Biopharm Proponents Claims

Inflated/Unrealistic

Farmers are unlikely to be major beneficiaries:

Market forces, including foreign competition, will drive down farmer compensation

Acreage required very small compared with commodity crop acreage, such that only a small number of growers will be needed

Genetic Modification of Algae and Trees

GE algae (for use as fuel): dangers include worldwide spread and possible weaponization to destroy fish stocks

Mercury-splicing bacteria for soil cleanup

Removes Hg 2+ ions from contaminated soil and converts it into volatile elemental mercury, which is released into the atmosphere

Problem - converted by phytoplankton to organic mercury, dispersed widely, and then works its way up the food chain

Genetic Modification of Vertebrates

Aquabounty Technology’s GE salmon (contains growth hormone gene from chinook salmon and genetic onswitch from the ocean pout)

Designed for more rapid growth

Aquabounty states it will only produce sterile females

Up to 15% may escape pens and interbreed with wild stocks, decreasing the species’ reproductive fitness

GE salmon have higher levels of IGF-1 (carcinogen)

WA, OR and MD have banned

Genetic Modification of Vertebrates

Tilapia/clotting factor VII

“Ruppy” (Ruby Puppy)

Glows red under UV light

Developed using red fluorescent gene from sea anemones

Artist Eduard Kac:

Glow-in-the-dark rabbit

“Plantimal” (petunia-human hybrid)

Genetic Modification of Vertebrates

“Popeye Pig” – Pig GM with spinach gene, designed to have less saturated fat

Pigs modified with roundworm gene to make their own

(heart healthy) omega-3 fatty acids

Accidentally turned up in poutry feed sold throughout

Ontario(2004)

Goats GM to make anti-nerve gas agent

Biopharming of Vertebrates

“Enviropig” – GM modified with E. coli and mouse DNA to digest phytates, decrease phosphate in excrement

Phytase (pig feed supplement) does same thing

Pig feed can already be supplemented with phytase

Idea shelved

Genetic Modification of Vertebrates

Cows modified to produce “human” milk

Proposal to genetically modify human embryos to make all humans intolerant to red meat (to combat global warming and overuse of water)

Genetic Modification of Vertebrates

USDA Office of the Inspector General has criticized

USDA for lacking coordinated oversight of regulations behind R and D of GE animals and insects

Human-Animal Hybrids

Inter-species breeding

Ape-man, Ilya Ivanovich Ivanov, Guinea, 1927

Stalin attempted to create interspecies (half-men/halfapes) “super-warriors”

2011: Chimeric monkey created from 6 different parents

Human-Animal Hybrids and More

UK scientists have created over 150 human-animal hybrid embryos to develop embyronic stem cells

De-extincting Neanderthal using human womb

Cloning of extinct species, “Pleistocene rewilding”

Synthetic Biology (Synbio)

Creation of DNA and organisms from scratch

Applications:

Biofuels

Industrial chemicals

Natural product substitutes - Rubber, vanilla, palm oil

Biomedical applications - Vaccine production

Synthetic Biology (Synbio)

2002: Polio virus created at SUNY Stony Brook over two years

2005: Mt Sinai, CDC researchers resurrect lethal 1918 flu virus and publish details of complete genome sequence

2012: Nature published instructions on how to create plague virus

Risks of Synbio

Accidental release into wild

Displacement of wild populations

Ecosystem disruption

Extinction

Synbio and Beyond

DARPA Project to create living, breathing creatures with possible military applications

Bio hackers (home and community laboratory creation of

GM organisms)
