The only approved firstline systematic therapy agent for HCC, sorafenib, is capable to properly boost advanced HCC patients’ survival. Having said that, it is actually progressively recognized that the therapeutic response to sorafenib could be drastically diminished immediately after brief term remedy, defined as main resistance. The present study is aimed to discover the function of stressinducible protein Sestrin2 (SESN2), among by far the most important sestrins members of the family, in sorafenib main resistance. Herein, we initially located that SESN2 expression was considerably upregulated in both HCC cell lines and tissues compared to standard human hepatocytes and corresponding adjacent liver tissues, respectively. Additionally, SESN2 expression was highly correlated with sorafenib IC50 of HCC cell lines. Thereafter, we showed that sorafenib remedy resulted in an increase of SESN2 expression and also the knockdown of SESN2 exacerbated sorafenibinduced proliferation inhibition and cell apoptosis. Further mechanistic study uncovered that SESN2 deficiency impaired both AKT and AMPK phosphorylation and activation immediately after sorafenib therapy. Moreover, the correlations among SESN2 expression and each phosphorAKT and phosphorAMPK expression have been illustrated in HCC tissues. Taken with each other, our study demonstrates that SESN2 activates AKT and AMPK signaling as a novel mechanism to induce sorafenib.
