When a RAS gene operates normally, it acts as an on/off switch for cell signaling to control cell proliferation. But when the gene mutates, the switch jams into the “on” position, allowing cells to proliferate uncontrollably. This unstoppable cascade inevitably leads to cancer. “The mutation in the gene is very common in pancreatic and colon cancer,” said Neil Kelleher, the […]
