Mechanism of sufentanil inhibiting proliferation, invasion and migration of hepatocellular carcinoma cell line MHCC97-H by regulating miR-1

Objective To explore the effect and mechanism of sufentanil on the proliferation, invasion and migration of human hepatocellular carcinoma cell line MHCC97-H by regulating microRNA-1 (miR-1) expression.Methods The start and end time of this research was from March 2018 to September 2019.The effects of different concentrations of sufentanil on the viability of human hepatocellular carcinoma cell line MHCC97-H were determined using the cell counting kit-8 (CCK-8) assay. The effect of sufentanil on the expression of miR-1 in MHCC97-H cells was detected by qRT-PCR. The miR-1 inhibitor and negative control were transfected into MHCC97-H cells using liposome-mediated transfection. There were control group, sufentanil group, sufentanil+NC group and sufentanil+miR-1 group in this study. The proliferation, invasion and migration ability of MHCC97-H cells in each group was detected by CCK-8 assay, Transwell assay, and scratch test, respectively. Western blotting was used to detect the expressions of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in MHCC97-H cells.Results Different concentrations of sufentanil had different inhibitory effects on the viability of MHCC97-H cells in vitro. Compared with the control group, the expression of miR-1 in MHCC97-H cells in the sufentanil group [(1.00±0.09) vs. (2.25±0.24)] was significantly higher (P<0.05), the cell proliferation [(0.54± 0.05) vs. (0.34±0.03)], invasion [(106.24±8.25) vs. (51.34±5.02)] and migration ability [(37.36±4.01)% vs. (16.34±1.72)%] decreased (P <0.05), and MMP-2 [(0.33±0.04) vs. (0.15±0.02)] and MMP-9 [(0.24±0.02) vs. (0.11±0.01)] expressions were down-regulated (P<0.05). Compared with sufentanil+NC group, the expression of miR-1 in MHCC97-H cells in the sufentanil+miR-1 group [(2.20±0.21) vs. (1.42±0.15)] was significantly reduced (P<0.05), cell proliferation [(0.32±0.03) vs. (0.46±0.04)], invasion [ (52.36±5.14) vs. (91.16± 6.06)] and migration ability [(17.11±1.71)% vs. (29.85±3.10)%] increased (P<0.05), and MMP-2 [(0.15±0.02) vs. (0.27±0.02)] and MMP-9 [(0.13±0.01) vs. (0.19±0.02)] expressions were up-regulated (P<0.05).Conclusion Sufentanil can inhibit the proliferation, invasion and migration of human hepatocellular carcinoma cell line MHCC97-H by regulating the expression of miR-1, whose mechanism may be related to the regulation of MMP-2 and MMP-9 expressions.
