Study implicates protein as a trigger of advanced prostate cancer recurrence Scientists with the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill have for the first time implicated a growth-promoting cellular protein as one trigger of the inevitable recurrence of advanced prostate cancer in men who are undergoing drug treatment to shut down their sex hormones, or androgens. view more (2007-05-09)
Computational model simulates AZT metabolism in mitochondria Researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed a computational model that allows scientists to better understand the metabolism and toxicity of the HIV/AIDS drug zidovudine (azidothymidine, AZT). view more (2006-07-25)
How Rett Syndrome mutation targets the brain Researchers have pinpointed why mutations that cause Rett Syndrome (RTT)-among the leading causes of mental retardation in females-specifically target the brain rather than other body tissues. view more (2006-10-19)
Funnel in the eye: Signal focusing increases photosensitivity In poor light the eyes of mice react like some digital cameras: they reduce their resolution while at the same time increasing their sensitivity. Specialists in the retina focus the information of several light sensor cells for this purpose. view more (2006-11-03)
Researchers identify new, cancer-causing role for protein The mainstay immune system protein TRAF6 plays an unexpected, key role activating a cell signaling molecule that in mutant form is associated with cancer growth, researchers at The University of Texas M. D. Anderson Cancer Center report in the Aug. 28 edition of Science. view more (2009-08-28)
