USP7 regulates growth and maintains the stemness of p53-mutant colorectal cancer cells via stabilizing of mutant p53

TP53 is one of the most frequently mutated genes among all cancers, and TP53 mutants occur more than 40% in colorectal cancers (CRCs). Accumulation of mutant p53 may augment colorectal cancer stem cells (CCSCs) phenotype and enhance colorectal tumorigenesis. Thus, reducing the level of mutant p53 protein is an attractive anticancer strategy.
