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 on April 7, 2021. "Decoding this major step in the way cells dispose of defective mitochondria has implications for a number of diseases."
