Pinelliae Rhizoma herbal-acupuncture solution induced apoptosis in human cervical cancer cells, SNU-17.

Pinelliae Rhizoma has been used traditionally in Korea to promote the liver Qi activity and the function of the digestive system. We investigated whether the Pinelliae Rhizoma herbal-acupuncture solution (PRHS) would induce cell-death on SNU-17, human cervical cancer cells. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to investigate the cytotoxicity of PRHS. The cell death was identified as apoptosis with 4, 6-diamidineo-2-phenylindole (DAPI) staining, and terminal deoxy-nucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) assay. PRHS could induce apoptosis of SNU-17 via Bax-related caspase-3 activation. The expressions of both Bax, a pro-apoptotic gene, and caspase-3, an apoptotic gene, were increased. The results might provide the experimental data for the clinical use of Pinelliae Rhizoma on cervical cancer.
