Cancer-causing fusion protein works by silencing tumor suppressor gene IL-2Rγ

Mariusz A. Wasik, MD, professor of Pathology and Laboratory Medicine, and Qian Zhang, MD, PhD, research assistant professor, both from the Perelman School of Medicine at the University of Pennsylvania, and their colleagues, found that a cancer-causing fusion protein works by silencing the tumor suppressor gene IL-2R common gamma-chain.

Scientist determines how nyctalopin gene makes night vision possible

A scientist from the Florida campus of The Scripps Research Institute has determined how a particular gene makes night vision possible. The study, which was published in the August 10, 2011 edition of The Journal of Neuroscience, focuses on a gene called nyctalopin. Mutations in the gene result in inherited "night blindness," a loss of vision in low-light environments.
