Restoring ability to halt cell division may protect lung cells from cancer

A novel role for a signaling mechanism in lung cells that permanently places them into a state of suspended animation called senescence has been identified by a team of researchers. Alive but unable to do much of anything, including divide, senescent cells cannot become cancerous. Drugs that can induce senescence through this signaling pathway would represent a new class of chemotherapy. (Mehr in: Cancer News — ScienceDaily)
