Researchers discover how tumor suppressor gene works

... Normally, p16 keeps cells from growing rapidly, a condition that sometimes leads to tumor formation. Working with mouse epidermis and cultured human melanoma and nonmelanoma cancer cells, the team found that p16 inactivates key enzymes -- called JNK 1 and JNK 2 -- in the process. The enzymes are normally acti...
