Ras is a family of genes encoding small GTPases involved in cellular signal transduction. If their signals are dysregulated, Ras proteins can cause cancer. Dr. Sharon Campbell explains her lab’s research into a novel mechanism for regulation of Ras proteins by reactive free radical species.
Thursday, October 15, 2009 — Dr. Xian Chen, Associate Professor of Biochemistry and Biophysics, who along with Dr. Morgan Giddings, Associate Professor of Microbiology and Immunology have been awarded a $1.6 million 2-year “Grand Opportunities” (GO) grant from the National Human Genome Research Institute.
Dr. Arrel Toews, Professor of Biochemistry & Biophysics receives the honor of giving this year's Richard H. Whitehead Lecture.
Congratulations to Dr. Aziz Sancar, Distinguished Professor of Biochemistry & Biophysics, receives the highest honor bestowed upon alumni of the University of Texas, Dallas.
Congratulations to Dr. Yi Zhang who has been named a Kenan Distinguished Professor effective July 1, 2009
Congratulations to Dr. Brian Strahl, Associate Professor of Biochemistry & Biophysics, for receiving the 2009 Phillip and Ruth Hettleman Award for Outstanding Artistic and Scholarly Achievement.
Monday, May 11, 2009 — Researchers at the University of North Carolina at Chapel Hill School of Medicine and UNC Lineberger Comprehensive Cancer Center have found that defects in one tumor-suppressor gene, called p18, may override the rest, eventually leading to cancer.
Congratulations to Arrel Toews, Research Professor of Biochemistry and Biophysics for winning the Tanner Award for Excellence in Undergraduate Teaching, the highest campus-based recognition for teaching undergraduates.
Researchers in Yi Zhang's group in the Dept. of Biochemistry & Biophysics at UNC-Chapel Hill have discovered a gene that when mutated causes obesity by dampening the body’s ability to burn energy while leaving appetite unaffected.
Researchers in Aziz Sancar's group in the Department of Biochemistry & Biophysics at UNC-Chapel Hill have shown that disruption of the circadian clock – the internal time-keeping mechanism that keeps the body running on a 24-hour cycle – can slow the progression of cancer.
A new study from Aziz Sancar's group in the Dept. of Biochemistry & Biophysics at UNC-Chapel Hill suggests that chemotherapy is most effective at certain times of day because that is when a particular enzyme system – one that can reverse the actions of chemotherapeutic drugs – is at its lowest levels in the body.
Dr. Richard Wolfenden, Alumni Distinguished Professor of Biochemistry & Biophysics, and member of the National Academy of Sciences, and co-author Charles Lewis, PhD publish a report in the November issue of the Proceedings of the National Academy of Sciences showing that without enzymes speeding the process, it would take 2.3 bilion years to complete vital biological transformation.
