Bioinformatics sheds light on evolutionary origin of Rickettsia virulence genes

Scientists from the Virginia Bioinformatics Institute (VBI) at Virginia Tech, the University of Maryland School of Medicine, and the University of Louisville have revealed that genes for a specific type of molecular secretion system in Rickettsia, a structure that is linked in many cases to virulence, have been conserved over many years of evolution.

Small molecules block cancer gene

Finding molecules that block the activity of the oncogene Stat 3 (signal transducer and activator of transcription) required screening literally millions of compounds, using computers that compared the structure of the cancer-causing gene to those of the small molecules, said a Baylor College of Medicine researcher in a report that appears in the current online issue of the journal PLoS One (Public Library of Science ONE).
