NetWalker Finds Protein Damage Clues

Friday, July 8th, 2011

Reactive molecules generated in the body – by toxic drugs, environmental chemicals and even the body’s own natural processes – can attack and chemically modify proteins to produce protein “adducts” which may play a role in human diseases. But just how these adducts are involved in toxicity and cellular responses to oxidant damage is unclear. […]

Study Details ‘On/Off’ Switch for Genes

Friday, August 27th, 2010

Turning the right genes “on” and “off” at the right times is critical for proper cell function. Faulty regulation of gene expression can contribute to cancer development. “If we can understand how genes are tightly regulated, then we might be able to target irregular gene expression for cancer treatment,” said Zu-Wen Sun, Ph.D., assistant professor […]
