Cellular Senescence Pathway

Molecular classification
Signaling Pathway, Cell Cycle Regulation, Tumor Suppressor Pathway
01

Overview

The cellular senescence pathway is a biological process leading to a stable cell cycle arrest, triggered by various stressors. It involves the p53/p21 and p16/Rb pathways, resulting in characteristic phenotypic changes and the secretion of the Senescence-Associated Secretory Phenotype (SASP). While initially beneficial for tumor suppression and tissue repair, chronic activation contributes to aging-related pathologies.
