    An ethanolic extracts of Scutellaria Baicalensis GEORGI are used to treat cancer, infectious diseases, and inflammation. In the present study, we investigated the effects of an ESBG on the growth and survival of 5637 cells, a human bladder carcinoma cell line. Cells were treated with different concentrations of an ethanolic extract of Scutellaria Baicalensis GEORGI (ESBG), and cell death was assessed using a MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay. Analyses of the sub G1 peak, caspase-3 and -9 activities, and mitochondrial membrane depolarizations were conducted to confirm cell death by apoptosis. ESBG had a cytotoxic effect on 5637 cells, and increased the sub G1 peak, caspase-3 and -9 activities, and mitochondrial depolarization, indicating ESBG induced apoptosis. Furthermore, MAPK (mitogen-activated protein kinases) inhibitors suppressed this apoptosis. In an in vitro study, a combination of sub-optimal doses of ESBG and paclitaxel, 5-fluorouracil, or docetaxel noticeably suppressed tumor growth by 5637 cells. Our findings provide insight of the mechanisms underlying cellular apoptosis induced by ESBG, and suggest new therapeutic strategies for bladder cancer.
