Sufentanil Inhibits Proliferation, Migration, and Invasion of Hepatocellular Carcinoma Cells by Upregulating miRNA-204

Abstract

Sufentanil is a powerful analgesic that acts on μ-receptors, but there are few studies on sufentanil in cancer. The biological function and underlying mechanisms of sufentanil on the hepatocellular carcinoma (HCC) cells were explored in the present study. HCC cells were first treated with different concentrations of sufentanil and the most optimum concentration of sufentanil was determined. The expression of miR-204 in HCC cells was changed by transfected with miR-204 inhibitor and the transfection efficiency was assessed by qRT-PCR. CCK-8, wound-healing and Transwell assays were performed to evaluate the proliferation, migration and invasion of HCC cells, respectively. The level of AKT and PI3K phosphorylation (p-AKT and p-PI3K) were assessed by western blot analysis. Our results demonstrated that sufentanil effectively inhibited cell proliferation,migration and invasion in both Huh7 and Hep3B cells, and significantly decreased the expression of p-AKT and p-PI3K. In addition, miR-204 was upregulated in Huh7 and Hep3B cells treated with sufentanil, and low expression of miR-204 attenuated the damage of sufentanil on the viability of Huh7 and Hep3B cells. Taken together, sufentanil suppressed the proliferation, migration and invasion of HCC cells via inhibiting AKT/PI3K signaling pathway by targeting miR-204.
