Downregulation of miR-501-3p increases cyclinD1 and c-Myc expression via targeting APC in colorectal cancer cells. (A) Downregulation of miR-501-3p decreased cyclinD1 and c-Myc mRNA expression levels, while APC silencing reversed the downregulation of cyclinD1 and c-Myc in HCT116 cells and in (B) Caco2 cells. (C) Downregulation of miR-501-3p decreased cyclinD1 and c-Myc protein expression levels, while APC silencing reversed the downregulation of cyclinD1 and c-Myc in HCT116 cells. (D) Quantitative analysis of cyclinD1 and c-Myc protein expression levels in C. (E) Downregulation of miR-501-3p decreased cyclinD1 and c-Myc protein expression levels, while APC silencing reversed downregulation of cyclinD1 and c-Myc in Caco2 cells. (F) Quantitative analysis of cyclinD1 and c-Myc protein expression levels in E. **P<0.01 and ***P<0.001, with comparisons indicated by lines. miR, microRNA; APC, adenomatous polyposis coli; NC, negative control; si, small interfering.
