Fig. 6From: Functional role of miR-10b in tamoxifen resistance of ER-positive breast cancer cells through down-regulation of HDAC4miR-10b and its target HDAC4 influence tamoxifen-induced apoptosis and cell viability. Effect of ectopic expression of miR-10b and HDAC4 on (a) apoptosis-induction and (b) viability of MCF-7 cells, and the effect of silencing of miR-10b and HDAC4 on (c) apoptosis-induction and (d) viability of MCF7TR cells. Tamoxifen treatment was for 48Â h. PM, pre-miR-10b; AM, anti-miR-10b; HDAC4, HDAC cDNA; siHDAC4, siRNA against HDAC4Back to article page
