Expression of ETV4 in HCC cell lines SMMC-7721 and HCC-LM3 treated with sorafenib or cisplatin and gene set enrichment analysis (GSEA). A: Western blotting of ETV4 expression in SMMC-7721 and HCC-LM3 cells treated with DMSO, sorafenib (5μmol/L) or cisplatin (5 μmol/L) for 48 h (error bars indicate SD; **P < 0.01 by One-way ANOVA); B: GSEA for analysis of gene enrichment in high and low ETV4 expression groups showing an enrichment score (ES) of 0.7768348 and a normalized enrichment score (NES) of 2.9248652
