Core Tip

Core Tip: Y-box binding protein 1 (YB-1) was significantly increased in hepatocellular carcinoma (HCC), and it could increase the IC50 values of sorafenib in HCC cell lines. Meanwhile, YB-1 suppressed apoptosis and cell proliferation inhibition induced by sorafenib. Furthermore, we screened the phosphoinositide-3-kinase (PI3K)/protein kinase B (Akt) signaling pathway to explore the molecular mechanism of sorafenib resistance by the KEGG pathway enrichment analysis of the digital gene expression profiling-seq. And the blockade of PI3K/Akt signaling pathway by LY294002 mitigated YB-1-induced sorafenib resistance. Given that sorafenib is the first-line treatment for patients with advanced HCC, we proposed that the down-regulation of YB-1 is of great significance for the application of sorafenib in advanced HCC.
