miR-140 targets and represses OGT expression. (A, B) Overexpression of miR-140 represses the OGT mRNA levels in PC3 and DU145 cells. NC: Negative control. (C, D) Overexpression of miR-140 represses the OGT protein expression and O-GlcNAC levels in PC3 and DU145 cells. (E) The putative miR-140 binding sequence in the 3′UTR of OGT. Red, mutations of the miR-140 binding site in the OGT 3′UTR. (F) Analyses of the luciferase activity of the luciferase reporter plasmids containing either wild-type (WT) or mutant-type (MT) OGT 3′UTRs in HEK-293 cells. *p < 0.05; **p < 0.01; ***p < 0.001 (Student’s t-test).
