Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and poses a severe threat to human health. Ginkgo biloba leaf polysaccharide (GBLP) is a bioactive component, and its sulphated derivative (sulfated GBLP, SGBLP) may exhibit high antitumor activity in certain types of cancers. However, the precise mechanisms of the SGBLP antitumor activity, particularly in HCC, remain unclear. Here, we assessed the effect of SGBLP on HepG2 hepatocellular carcinoma cells. SGBLP was shown to inhibit cellular proliferation and promote apoptosis through the regulation of pro- as well as anti-apoptosis markers, and to induce autophagy by supressing the PI3K/AKT/mTOR pathway. In addition, the autophagy inhibitor 3-melyladenine (3-MA) enhanced the antiproliferative and proapoptotic effects of SGBLP in HepG2 cells. Thus, SGBLP exhibits antitumor activity, and its combination with an autophagy inhibitor may represent a promising anticancer strategy in the treatment of HCC.
期刊介绍：
Molecular Biology is an international peer reviewed journal that covers a wide scope of problems in molecular, cell and computational biology including genomics, proteomics, bioinformatics, molecular virology and immunology, molecular development biology, molecular evolution and related areals. Molecular Biology publishes reviews, experimental and theoretical works. Every year, the journal publishes special issues devoted to most rapidly developing branches of physical-chemical biology and to the most outstanding scientists.
