SOX9 and endometrial cancer: The completed molecular analysis indicated that mRNA TGFβ1, TGFβ2, WNT5A, TGFB2, NOTCH1, BCL2L, SOX9, BAMBI, SMAD4, and STAT1 as well as miR-30d, miR-144, and miR-106a are connected with the epithelial–mesenchymal transition in endometrial cancer and can be considered as supplementary, diagnostic molecular markers.
