Construction of HCC cell lines with overexpression or downregulation of PCSK9. a Relative mRNA expression level of PCSK9 in HCC cell lines and a normal hepatocyte cell line (L02). b Transfection efficiency of PCSK9-overexpressing virus in the HCCLM3 cell line. c Transfection efficiency of PCSK9-knockdown virus in the HepG2 cell line. d Relative mRNA expression level of PCSK9 in the HCCLM3 cell line (p < 0.001). e Western blot images and summarized data showing that PCSK9 was successfully overexpressed in the HCCLM3 cell line (p = 0.014). f Relative mRNA expression level of PCSK9 in the HepG2 cell line (p = 0.004). g Western blot images and summarized data showing that PCSK9 was successfully downregulated in the HepG2 cell line (p = 0.001). *p < 0.05, **p < 0.01, ***p < 0.001
