SFN and hepatocellular carcinoma: To explore the function of SFN expression in HCC, we first compared the expression level of SFN in 7 HCC cell lines and the results showed that SFN mRNA (Fig. 9F) and protein level (Fig. 9G) in Huh7, Sk-Hep-1, and Hep3B cell lines were the highest compared with the L02 cells.
