In contrast, negative correlation with TP53 expression was discovered in four cancers, including COAD (MLH1 correlation coefficient/P-value = −0.42/0.0009), UCEC (MLH1 correlation coefficient/P-value = −0.47/0.0005), SKCM (PMS2 correlation coefficient/P-value = −0.5/0.0097), and STAD (PMS2 correlation coefficient/P-value = −0.25/0.04). This evidence concerns the gene PMS2 and cancer.
