Effects of miR-142-3p on SIRT1 expression. (A) RT-qPCR and (B) western blotting were used to detect the mRNA and protein expression levels of SIRT1 in SKOV3 and SKOV3/DDP cells transfected with miR-142-3p mimic or miR-NC, respectively. **P<0.01 vs. miR-NC. Subsequently, SKOV3 and SKOV3/DDP cells were transfected with anti-miR-142-3p or anti-NC, respectively. Non-transfected cells were used as the control group. (C) Post-transfection, RT-qPCR was used to examine the miR-142-3p expression. **P<0.01 vs. Control. (D) RT-qPCR and (E) western blotting were used to detect the mRNA and protein expression levels of SIRT1. **P<0.01 vs. anti-NC. miR, microRNA; miR-NC, negative control (scramble) miR; anti-miR-142-3p, miR-142-3p inhibitor; anti-NC, negative control inhibitor; RT-qPCR, reverse transcription-quantitative polymerase chain reaction; SIRT1, sirtuin 1.
