  • Progress in regulation of centromere protein family on malignant biological behavior of hepatocellular carcinoma

    ObjectiveTo understand the clinical value of centromere proteins (CENPs) in hepatocellular carcinoma and their influence on the malignant biological behavior of hepatocellular carcinoma, and to provide theoretical references for related research in this field. MethodDomestic and international databases were searched for relevant literatures on the study of CENPs in hepatocellular carcinoma in recent years to be analyzed and reviewed. ResultsA total of 11 CENPs closely related to hepatocellular carcinoma had been summarized, which were differentially expressed in hepatocellular carcinoma and correlated with prognosis. CENPs might regulate various malignant biological behaviors such as hepatocellular carcinoma proliferation, metastasis, apoptosis, and resistance to radiotherapy and thus participate in the development of hepatocellular carcinoma via multiple mechanisms. The roles and mechanisms of some CENPs in hepatocellular carcinoma remained unclear. ConclusionsCENPs play an essential role in the diagnosis, treatment, and prognosis of hepatocellular carcinoma. They are involved in multiple malignant biological behaviors of hepatocellular carcinoma and are expected to be potential therapeutic targets for hepatocellular carcinoma. However, their roles and mechanisms in hepatocellular carcinoma remain to be investigated.

  • Resveratrol inhibits proliferation of hepatoma cells via PI3K p85/Akt signaling axis

    ObjectiveThis study aims to study the effects and mechanism of resveratrol on hepatocellular carcinoma (HCC) cells through phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) axis.MethodsHepG2 cells at logarithmic growth stage were treated with different concentrations (0, 12.5, 25.0, and 50.0 μmol/L) of resveratrol, respectively. Then the proliferation of HepG2 cells was detected by the CCK8 method and real time cell anaIysis (RTCA) system, the expressions of signal molecules associated with PI3K/Akt axis was detected by the Western blot method, including PI3K p58, phosphorylation protein kinase B (p-Akt), total protein kinase B (t-Akt), and CyclinA2 protein.ResultsResveratrol had a significant inhibitory effect on the growth of HepG2 cells in a time and dosage dependent manner. After 48 h treatment of resveratrol to HepG2 cells, 50.0 μmol/L resveratrol inhibited the growth of HepG2 cells most significantly. Further, the RTCA system studies also found that resveratrol had a time and concentration dependent effect on the reduction of normalized cell index (NCI) in HepG2 cells. Flow cytometry results showed that, apoptosis rates of 12.5, 25.0, and 50.0 μmol/L group were higher than that of 0 μmol/L group. Compard with 0 μmol/L group, the expressions of PI3K p85, p-Akt, and CyclinA2 protein in HepG2 cells of 12.5, 25.0, and 50.0 μmol/L resveratrol group was significantly higher (P<0.05), although there was no significant effect of resveratrol on the expression of t-Akt in HepG2 cells (P>0.05).ConclusionsResveratrol might have anti-proliferation effects on HepG2 cells through PI3K p85/Akt signaling axis. This study could provide a novel idea for the treatment to HCC.
