General description
The tumor suppressor p53 transcriptionally activates a number of genes including the WAF1/CIP1 gene in response to DNA damage. The ~21 kDa product of the WAF1 gene is found in a complex involving cyclins, CDKs, and PCNA in normal cells but not transformed cells and appears to be a universal inhibitor of CDK activity. One consequence of p21WAF1 binding to and inhibiting CDKs is the prevention of CDK-dependent phosphorylation and subsequent inactivation of the Rb protein which is essential for cell cycle progression. p21WAF1 is, therefore, a potent and reversible inhibitor of cell cycle progression at both the G1 and G2 checkpoints, presumably to allow sufficient time for DNA repair to be completed. Irreversible G1 or G2 arrest leads to apoptosis. While the role of p21WAF1 in apoptosis is less clear, it is known that p53-mediated apoptosis leads to increased WAF1 expression. Induction of p21WAF1 can occur by both p53-dependent and p53-independent mechanisms, in response to certain observed conditions. p21WAF1 has also been identified as a gene involved in cellular senescence, termed sdi1. Its overexpression was observed to inhibit cellular growth.

Securin overexpression correlates with poor prognosis in various tumours. We have previously shown that securin depletion promotes radiation-induced senescence and enhances radiosensitivity in human cancer cells. However, the underlying molecular mechanisms and the paracrine effects remain unknown. In this study
