LA JOLLA–(April 7, 2021) When cells are stressed, chemical alarms go off, setting in motion a flurry of activity that protects the cell’s most important players. During the rush, a protein called Parkin hurries to protect the mitochondria, the power stations that generate energy for the cell. Now Salk researchers have discovered a direct link between a master sensor of cell stress and Parkin itself. The same pathway is also tied to type 2 diabetes and cancer, which could open a new avenue for treating all three diseases.

“Our findings represent the earliest step in Parkin’s alarm response that anyone’s ever found by a long shot. All the other known biochemical events happen at one hour; we’ve now found something that happens within five minutes,” says Professor Reuben Shaw, director of the NCI-designated Salk Cancer Center and senior author of the new work, detailed in Science Advances
