Core Tip
Core tip: Dysregulation of p53 tumor suppressor gene is one of the most frequent events contributing to the transformation of colorectal cancer (CRC), as well as the aggressive and metastatic features of CRC. Mutant p53 reactivator, PRIMA-1MET has been tested in Phase I/II clinical trials and shows encouraging benefits. In this review, we systemically and comprehensively summarize the current understanding of p53 mutations in the pathogenesis of CRC and current progress in reactivation of p53 as a novel therapeutic strategy. We hope this review will promote more investigations of reactivation of p53 as a viable treatment option of patients with CRC.
