Objective: This study was to further investigate the effect of CDC25A gene on proliferation, invasion and metastasis of hepatocellular carcinoma HepG2 cells, and to explore whether CDC25A and IL6 interact in liver cancer. Methods: HepG2 cells were transfected with lentiviral CDC25A-shRNA to specifically block the expression of CDC25A in the experimental group (KD group), transfected with lentiviral-negative shRNA as a negative control group (NC group), and the conventionally cultured HepG2 cells were blank control group (Control group). Real-time quantitative PCR and Western blot were used to detect the mRNA and protein expression levels of CDC25A and IL6. Results: The expression level of IL6 mRNA in the experimental group was 0.4650.026, which was significantly lower than that of the negative control group of 1.0940.179 and the blank control group of 1.0020.311. The difference was statistically significant(P<0.05). The protein expression level of IL6 was 0.4990.061, which was significantly lower than the negative control group of 1.3110.034 and the blank control group of 1.2530.035. The difference was statistically significant (P<0.05). Conclusions: The CDC25A gene in hepatoma HepG2 cells was silenced, while the expression of IL6 was down-regulated. CDC25A may play a role in the development and invasion of liver cancer by regulating the expression of IL6.
