摘要
Many polysaccharides have biological activities and have been investigated for their antitumor effects. In this study, we investigated the anti-tumor activity and anti-virus activity of SNP the water-soluble polysaccharides extracted from Sipunculus nudus on Hepg2.2.15. Flow cytometry analysis demonstrated that SNP induced dose-dependent cell apoptosis on Hepg2.2.15. Real-time PCR and Western Blot analysis showed that SNP down-regulated the synthesis of HBsAg, HBV-DNA and enhanced the expression of pro-apoptosis proteins TNF-alpha, caspase-3, and Bax, while decreasing the expression of the antiapoptosis proteins survivin, Bcl-2, and VEGF. These results suggested that SNP suppressed cell viability of Hepg2.2.15 and that could be a novel anti-tumor and anti-HBV agent.
