Specifically, pancreatic adenocarcinoma (PAAD) (p-value = 0.0428) and uterine corpus endometrial carcinoma (UCEC) (p-value = 0.00268) presented negative correlations; hence, lower ESR2 expression correlated with tumor grade, as shown in Figure 2b. This evidence concerns the gene ESR2 and uterine corpus endometrial carcinoma.
