A Schematic illustrating the putative E2F1-binding sites in miR-532 promoter. B, C qRT-PCR analysis of miR-532 or pre-miR-532 levels in MKN-45 cells after changing E2F1 expression. D qRT-PCR analysis of CLCN5 mRNA levels in MKN-45 cells after changing E2F1 expression.(E, F Direct binding of E2F1 to miR-532 promoter as indicated by ChIP assays. Binding was confirmed by semi-quantitative PCR, followed by gel electrophoresis. G Luciferase reporter assay confirmed the suppression of miR-532 promoter by E2F1. *P < 0.05; **P < 0.01; ***P < 0.001.
