F ERβ Formulation sorafenib contained aberrant activation of PI3K/Akt pathway, stemness
F sorafenib contained aberrant activation of PI3K/Akt pathway, stemness along with the epithelialmesenchymal transition.16,50 It is actually sensible for clinical therapy to understand the essence of sorafenib resistance and develop potential technique to get rid of it. In this investigation, we observed that CYP2C8 might be a possible biomarker to relieve sorafenib resistance. In theory, CYP2C8-mediated PI3K/Akt pathway inhibition can effectively boost the anticancer effect of sorafenib. Actually, both in vivo and in vitro assays confirmed that CYP2C8 over-expression significantly enhanced sorafenib-induced cell death, accompanied by a reduce in Ki-67 and inhibition of PI3K/AKT/P27 axis. There were no research suggesting that CYP450 induce resistance by accelerating metabolism of sorafenib so far. As a result, the development of CYP2C8 activating agents is expected to improve the anticancer effect of sorafenib. Moreover, activation of CYP2C8 may well be beneficial to improve the metabolism of sorafenib and alleviate the toxic and unwanted side effects induced by sorafenib. In conclusion, CYP2C8 is an antioncogene influencing HCC cells’ proliferation, clonality, migration and invasion by means of PI3K/Akt/p27kip1 axis, and CYP2C8 may also serve as a diagnostic and prognostic marker for HCC. Moreover, the up-regulated expression of CYP2C8 drastically enhances the therapeutic effect of sorafenib. Our study suggests that the regulation of CYP2C8 may perhaps contribute to the improvement of prognosis in sufferers with HCC.Council for Science (ICLAS) and NC3Rs ARRIVE Guideline, and this study had acquired the approval of the Ethics Committee on the initial affiliated hospital of Guangxi Medical University before specimen collection and animal tests.
