Flipping the ‘off’ switch on cell growth

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.
