The co-transfection experiments of miR-200b, miR-200c, and miR-429 mimics or miR-NC with pLightSwitch_3′UTR reporter vectors containing the 3′UTR sequence of SESN1 revealed no significant change in luciferase activity in any of the analyzed endometrial cancer cell lines (Fig. 2a1–4). This evidence concerns the gene SESN1 and endometrial cancer.
