Fig. 6From: Butyrate inhibits pro-proliferative miR-92a by diminishing c-Myc-induced miR-17-92a cluster transcription in human colon cancer cellsHDAC inhibitors, SAHA and valproic acid, suppressed expression of pri-miR-17-92a, miR-92a and c-Myc in colon cancer cells. HCT116 human colon cancer cells were treated with 0.5 uM SAHA or 1 mM valproic acid for 24 h before harvesting. The abundance of a) pri-miR-17-92a and b) miR-92a was measured using qPCR. Bars represent means ± SEM. n = 4. c Protein levels of c-Myc and β-actin were analyzed by immunoblotting. The image shown is representative of three individual experiments. d Relative c-Myc protein levels were measured by densitometry. Bars represent means ± SEM. n = 3Back to article page
