Wild-type p53 negatively regulates hMSH2 expression by repressing promoter activity in normal human oral keratinocytes.
Both p53 and hMSH2 are essential for maintaining genomic integrity, yet the regulatory link between them remains poorly understood. This study investigates the transcriptional repression of the DNA mismatch repair gene hMSH2 by wild-type p53 in normal human oral keratinocytes (NHOKs). We observed that inducing p53 with...
