MAPK7 and uterine corpus endometrial carcinoma: Gene expression data mining from the cBioPortal for Cancer Genomics (Uterine corpus endometrial carcinoma TCGA, PanCancer Atlas), using the database GEPIA2 (http://gepia2.cancer-pku.cn/#index), showed a strong positive correlation between MAPK7 and RELA mRNA expression levels (R, 0.47; Spearman, 8.2e−11: Fig. 4A).
