Human Genetic Variation Alters Anthrax Toxin Sensitivity
Martchenko, Candille et al., PNAS
Researchers at Stanford University School of Medicine show that genetic variation affecting capillary morphogenesis gene 2, or CMG2, dramatically alters toxin sensitivity in humans. In its analysis, the team reports on "a CMG2 single-nucleotide polymorphism occurring frequently in African and European populations [that they found] independently altered toxin uptake." The group goes on to suggest "testing of genomically characterized human cell populations may offer a broadly useful strategy for elucidating effects of genetic variation on infectious disease susceptibility."
NIH Invests $161M in 14 New Pharmacogenomics Research Network Projects
With this new funding, the NIH hopes to continue PGx research in existing focus areas of cancer, heart disease, asthma, and nicotine addiction, and also to expand into new areas, including rheumatoid arthritis and bipolar disorder.
