The anti-inflammatory, anti-diabetes, anti-metabolic syndrome, anti-tumor, and anti-endotoxin effects of emodin are explored. Emodin enhances antitumor effect of gemcitabine in model of SW1990 cell xenograft on athymic mouse. Emodin can significantly improve the antitumor effect of gemcitabine on transplanted tumor of SW1990 cell line through apparently enhancing the tumor cell apoptosis by gemcitabine. Downregulation of [...]
