Gladstone scientists identify gene critical for cell responses to oxygen deprivation
Date:11/3/2011

rst activated the p75NTR protein, which then activated HIF1-alpha and set everything in motion.

"What was most striking to us was what happened when we removed the gene that makes p75NTR," said Natacha Le Moan, PhD, a Gladstone postdoctoral fellow and the first author of the paper. "By effectively silencing p75NTR, the mice's response to hypoxia was impaired and blood-vessel production decreased."

"Now that we've shown that p75NTR spurs the activation of HIF1-alpha and the production of blood vessels during hypoxia, we can move forward with exploring potential therapies," said Dr. Akassoglou, who is also an associate professor of neurology at the University of California, San Francisco, with which Gladstone is affiliated. In addition, Dr. Akassoglou is also an associate adjunct professor of pharmacology at the University of California, San Diego.

"Dr. Akassoglou's trailblazing discovery could enable the development of pharmaceutical therapies for conditions that are caused or exacerbated by reduced oxygen levels," added Lennart Mucke, MD, who directs neurological research at Gladstone. "This is important news for those who suffer from hypoxia-related illnesses such as heart disease, stroke and certain types of cancer."
