To verify whether the screened drugs have inhibitory effects on the expression of SRSF9, the hepatoblastoma cell line HepG2 and hepatocellular carcinoma cell lines Huh-7 and Hep3B were treated with camptothecin (10 μM) and apigenin (40 μM) for analyses of SRSF9 expression by RT-PCR. Here, SRSF9 is linked to hepatocellular carcinoma.
