DNMT1 and non-small cell lung carcinoma: These data suggest that 1) increased DNMT1 may not alter miR- 542-3p expression in NSCLC; 2) although miR-542-3p contributes to entinostat-induced growth inhibition and apoptosis in vitro, it has little effect on entinostat potentiation of paclitaxel efficacy in vivo.
