Figure 3 Hepatocellular carcinoma cell line screening. Hepatocellular carcinoma cell lines HepG2, SMMC-7721, and Huh-7 were screened for HHLA2 expression. HL-7702 cells were used as normal liver cells. (A) Relative HHLA2 mRNA levels based on qRT-PCR assay. * P<0.05. (B) Western blot analysis of HHLA2 protein. β-tubulin was used as an endogenous control. (C) HepG2 cells were transfected with lentivirus expressing 1 of 3 shRNAs targeting HHLA2 or a control shRNA, and HLLA2 knockdown efficiency was measured after 48 h by western blotting. HepG2+shRNA 1 caused the strongest knockdown (*** P<0.001). Actin was used as an endogenous control.
