AbstractStudies on aging have centered on two molecular pathways: CDK4/6 and insulin/mTORC1. These pathways are thought to influence aging through distinct mechanisms: mTORC1 by reprogramming systemic metabolism, and CDK4 through p16-mediated senescence and inflammatory signaling (SASP). Here, we investigate the connection between aging and CDK4 in Caenorhabditis elegans, an organism lacking both p16 and SASP. Using a conditional degradation system, we demonstrate that CDK-4 inhibition in C.

AbstractIn response to stress, cells activate signaling pathways that coordinate broad changes in gene expression to enhance cell survival. Remarkably, complex variations in gene expression occur even in isogenic populations and in response to similar signaling inputs. However, the molecular mechanisms underlying this variability and their influence on adaptive cell fate decisions are not fully understood.
