HHMI professor, 138 undergraduates identify essential genes in eye formation
...ee and his students identified 501 essential genes responsible
for processes such as repair, cell death, and cell replication in the fruit fly's developing eye. They report the results of their research and the impact of their research-based learning project in the February 2005 issue of PLoS (Public Library of...

Studies reveal methods viruses use to sidestep immune system
... factor 3 (IRF-3). This protein turns on the genes responsible
for producing interferon, which neutralizes viruses by suppressing their replication. The researchers also investigated why cells with functioning RIG-I protein still had persistent HCV infection. In a study to appear in PNAS, Dr. Gale and his group...

Inherited gene may increase risk for prostate cancer by 50%
...ancers. This was the first single gene shown to be responsible
for the majority of cases of this disease, which affects approximately 200,000 men each year. This finding led to the question as to whether or not mutations in this gene that are present from birth might increase an individuals susceptibility to pro...
