摘要: Isatis indigotica is a biennial herbaceous cruciferous medical herb with antipyretic, antiviral, anti-inflammatory, and anti-endotoxin activity. This study explored the chemotherapeutic potential of I indigotica on human hepatoma cells and investigated the mechanism by which metabolites from I indigotica inhibit hepatoma cell growth. Antitumor activity was discovered in dried I indigotica leaf chloroform extracts (CEDLI). In nude mice xenotransplanted with human hepatoma cells, CEDLI supplementation inhibited tumor growth by similar to 40% compared with nonsupplemented animals without affecting body weight/food intake. CEDLI induced sub-G1 cell cycle arrest and apoptosis in hepatoma cells. Furthermore, CEDLI activates p53 and Bax, reduces Bcl-2 expression, and causes mitochondrial stress and the release of apoptosis-inducing factor into the cytosol followed by its translocation into the nucleus, resulting in hepatoma cell apoptosis. This study provides novel in vivo evidence of I indigotica's antitumor activity. The chemotherapeutic activity against human hepatoma tumorigenesis was because of a distinguished caspase-independent apoptotic pathway.
