Effect of siRNA silencing MUC16 on the proliferation and migration of gallbladder carcinoma cells

ObjectiveTo explore the effects of siRNA silencing mucin 16(MUC16) on the proliferation and migration of gallbladder carcinoma GBC-SD cells, and its molecular mechanisms.

MethodsThe GBC-SD+MUC16-siRNA group was constructed using the lentivirus infection and siRNA interference technique to silence MUC16 gene in GBC-SD cells, and the negative control group(GBC-SD+NC group) and blank control group(GBC-SD group) were set up simultaneously.The RT-PCR was used to detect the expression of MUC16 in GBC-SD cells, the MTT and scratch assays were used to detect the proliferation and migration ability of GBC-SD cells, and the Western blotting was used to detect the protein expressions of CD44 and PCNA in GBC-SD cells.

ResultsThe cell proliferation rate and cell migration number in GBC-SD+MUC16-SiRNA group were lower than those in GBC-SD group(P < 0.05).The expression levels of MUC16 and CD44 protein in GBC-SD+MUC16-SIRNA group were lower than those in GBC-SD group and GBC-SD+NC group(P < 0.05 to P < 0.01), and the expression level of PCNA protein in GBC-SD+MUC16-SIRNA group was also lower than that in GBC-SD+NC group(P < 0.05).

ConclusionsSiRNA silencing MUC16 can inhibit the proliferation and migration of gallbladder cancer cells, which may provide the new experimental evidence for the treatment of gallbladder cancer.
