Abstract/OtherAbstract:
BACKGROUND: Few researches on increase of chemotherapy sensitivity by microRNA (miRNA) werereported. We aim to investigate exact role of miR-381 in chemotherapy sensitivity of 5-fluorouracil (5-FU) inrenal cancer cells.METHODS: We investigated the cell survival, cell-cycle and apoptosis of 786-O and HK-2 cells treated withmiR-381 and 5-FU. IC50 of 5-FU was calculated. To study apoptosis and G2/M arrest, we determined pHH3, mitotic index and caspase-3/7 activity.
RESULTS: We showed that miR-381 combined with 5-FU inhibited proliferation and potentiated the antitumourefficacies of 5-FU at tolerated concentration in vitro. miR-381 combined with 5-FU led to Cd c2activation, mitotic catastrophe, and cell apoptosis through inhibitory WEE1. WEE1 was also validated as the direct target of miR-381. IC50 of 5-FU decreased significantly in the presence of miR-381.CONCLUSION: miR-381 increases sensitivity of 786-O cells to 5-FU by inhibitory WEE1 and increase of Cd c2activity.
