Knockdown of HDAC11 suppressed sorafenib resistance of HCC in vitro. (A) High expression of HDAC11 indicated poor prognosis in sorafenib-treated HCC from TCGA database. (B,C) HDAC11 mRNA and protein were significantly upregulated in SMMC7721/SR compared with SMMC7721. (D,E) HDAC11 expression was markedly decreased after treatment of siRNAs targeting HDAC11. (F,G) Inhibition of HDAC11 suppressed sorafenib resistance of SMMC7721. (H,I) Inhibition of HDAC11 suppressed sorafenib resistance of SMMC7721/SR. (J,K) Inhibition of HDAC11 attenuated colony formation of HCC cells. (L) GSEA suggested that drug metabolism cytochrome P450 pathway was significantly enriched in HDAC11-low expression group. *P < 0.05, **P < 0.01, ***P < 0.001.
