Chaperone biomarkers of lifespan and penetrance track the dosages of many other proteins
Abstract
In C. elegans the chaperone hsp-16.2 predicts the penetrance of mutations and lifespan after heat shock, but it is not known why cells express different amounts of hsp-16.2. Here the authors show hsp-16.2 tracks differences in global gene expression capacity, rather than differences in signaling or intrinsic noise in adult intestine cells.
