Background Information
p16INK4a is a pivotal protein encoded by the CDKN2A gene on human chromosome 9p21. It functions as a tumor suppressor and is one of the most important regulators of the cell cycle. It acts as a cyclin-dependent kinase (CDK) inhibitor, specifically binding to CDK4 and CDK6 and blocking their association with cyclin D. Beyond cell-cycle control, p16INK4a is a key mediator of cellular senescence-an irreversible growth-arrest state that limits the expansion of damaged or oncogene-expressing cells. Its expression rises with age and in response to stresses such as DNA damage or oncogenic signaling, making it a biomarker of both biological aging and tumorigenic stress. In human cancers, the p16INK4a-RB pathway is frequently disabled through CDKN2A deletion, mutation, or promoter hyper-methylation, underscoring its importance in tumor suppression.
