The results of CCK8 and cell account displayed that the OD value of miR‐NC+pcDNA3.1/c‐met group was obviously higher than that of miR‐NC group (P < 0.05) (Figure 7B‐C), suggesting that the weakened effects induced by miR‐613 on retinoblastoma cells’ proliferation were inhibited by c‐met. This evidence concerns the gene MET and retinoblastoma.
