Protein Uses Multiple Means To Help Cells Cope When Oxygen Runs Low

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery has wide-ranging implications, they say, given the importance of this copying - known as DNA replication - and new cell growth to many of the body's functions and in such diseases as cancer. "We've long known that this protein, HIF-1α, can switch hundreds of genes on or off in response to low oxygen conditions," says Gregg Semenza, M.D., Ph.D... via Health News from Medical News Today Read More Here..
