The GM process produces a NEW organism with different, potentially unknown properties. The GM process produces a NEW organism with different, potentially unknown properties. Thus the route of exposure and virulence may have changed requiring altered containment. Thus the route of exposure and virulence may have changed requiring altered containment. Therefore it is a legal requirement for all GM work to be i) notified to HSE and ii) can only be carried out in registered GM centres Therefore it is a legal requirement for all GM work to be i) notified to HSE and ii) can only be carried out in registered GM centres Newcastle University's GM Centre Reference number is GM540 Newcastle University's GM Centre Reference number is GM540 Note: HSE tend not to accept that the new (GM) organism may be less viable or less infective even if it is a deletion transgenic organism.

Smallpox was responsible for 3-500 million deaths in the 20 th Century alone! Smallpox was responsible for 3-500 million deaths in the 20 th Century alone! 13 Slide 14 Occupational Health & Safety Service 14 1) One of the most cited examples of dual-use research is that of Australian researchers who inadvertently developed a lethal mouse virus. In this now-famous study, the researchers used standard genetic engineering techniques to insert the gene for interleukin-4 (IL-4) into the mousepox virus. They hoped that the altered virus would induce infertility in micewhich are a major pest in Australiaand would thus serve as an infectious contraceptive for pest control. To their surprise, they discovered that the altered virus could kill both mice that were naturally resistant to, and mice that had been vaccinated against ordinary mousepox. When they published their findings, along with a description of the materials and methods, in the Journal of Virology in 2001 ( Jackson et al, 2001), critics complained that they had thereby alerted would-be terrorists to new ways of making biological weapons and had provided them with explicit instructions.Jackson et al, 2001 vaccine-resistant strain of smallpox Of particular concern was the possibility that the same techniques used to engineer the mousepox virus could be applied to create more virulent forms of poxviruses that afflict humans, including a vaccine-resistant strain of smallpox; one of the most devastating diseases in human history. Although it was eradicated in the 1980s, fears remain that former Soviet stockpilesor genetically reconstituted forms of the viruscould be put to use by nefarious agents. Boy this is scarythis is the kind of thing that science fiction is made of. This research was the first example of a virus overcoming vaccination, and this was very worrying. And I suppose there was a little bit of excitement about it as wellit wasn't all doom and gloom. This is exciting stuff, no matter how evil or bad it may turn out to be. We went away wondering what to do about it. In those times there was no pathway in the structure of scientific institutions for resolving a case like this. EMBO reports (2010) 11, 18 - 24 Published online: 11 December (2009) An interview with Ronald Jackson and Ian Ramshaw This was the first example of a virus overcoming vaccination, and this was very worrying http://www.nature.com/embor/journal/v11/n1/full/embor2009270.html http://www.nature.com/embor/journal/v11/n1/full/embor2009270.html Severe Unknown Risks Interleukin-4 (IL-4) mousepox virus Slide 15 Occupational Health & Safety Service 15 2) Catastrophic failure of recombinant antibody In its first human clinical trials, recombinant CD28- SuperMAB an immunomodulatory drug being developed for treatment of leukemia and rheumatoid arthritis, caused catastrophic systemic organ failure in the subjects, despite being administered at a sub-clinical dose 500 times lower than the dose found safe in animals. Six volunteers were hospitalized, at least four of these suffering from multiple organ dysfunction. trial subjects was an unpredicted biological action of the drug in humans The molecule was genetically engineered by transfer of the complementarity determining regions (CDRs) from heavy and light chain variable region sequences of a monoclonal mouse anti-human C28 antibody into human heavy and light chain variable frameworks. Humanised variable regions were subsequently recombined with a human gene coding for the IgG4 gamma chain and with a human gene coding for a human kappa chain, respectively. The recombinant genes were transfected into Chinese hamster ovary cells and the recombinant antibody harvested from culture supernatant.

Science 2005; 310: 77-80 4) Spanish Flu Virus: A more recent study, published in Science in 2005, employed techniques of synthetic genomics (similar to those used in the polio study) to reconstruct the Spanish Flu virus, which killed between 20 and 100 million people in 1918-19.

Proc Natl Acad Sci USA 2002; 99: 8808-13 3) Smallpox Immune Evasion: In a third study, published in the Proceedings of the National Academy of Sciences in 2002, researchers used published DNA sequences to engineer a protein known as SPICE produced by the smallpox virus. 8 The study revealed the ways in which, and the extent to which, this protein defeats the human immune system. Though the findings may facilitate development of protective medicines, they may also reveal ways to increase the virulence of the closely-related vaccinia virus (which is used in the smallpox vaccine).

Science 2002; 297: 1016-8 2) Synthetic Virulent Polio Virus: In a second study, researchers at the State University of New York at Stony Brook artificially synthesized a live polio virus from scratch. 6 Following the map of the polio virus RNA genome, which is published on the Internet, they stitched together corresponding strands of DNA, which they purchased via mail-order. The addition of protein resulted in the creation of a virus that paralysed and killed mice. Upon publication of results in Science in 2002, the researchers said they made the virus to send a warning that terrorists might be able to make biological weapons without obtaining a natural virus. 7 Similar techniques might enable production of smallpox or Ebola.
