Gamisoamsan is a prescription originated in Soamsan which is known as an anti-cancer remedy in the traditional Korean Medicine. To enhance the synergic effects of anti-cancer activity of Soamsan, this study reconstituted the original components of Soamsan with a slight modification and produced a novel herbal remedy, namely Gamisoamsan. To investigate the effects of Gamisoamsan on anti-cancer reaction, I studied the effects of Gamisoamsan on angiogenesis via chorioallantoic membrane (CAM) assay, corneal neovascularization assay and the effects on expression of growth factor which are VEGF, TGF-β, bFGF and IMUP-1. Anti-cancer effects of Garnisoamsan was also abserved through hematological parameters, tumor volume and survival rate in mice. Gamisoamsan inhibited embryonic angiogenesis of blood vessels in CAM assay and inhibited neovascularization of rat cornea. Gamisoamsan reduced cell proliferation in HT1080 cells and IC50 was 2.18 mg/ml. Gamisoamsan reduced the expression of VEGF, TGF-β, bFGF and IMUP-1 which was known as vascular growth factor and this effects of Gamisoamsan was predominant than VP-16. The treatment of Gamisoamsan decreased the CT-26 cell inoculated-tumor volume in mice colon adenocarcinoma and increased mice survival which was inoculated CT-26 cells. The results of the present study suggest that Gamisoamsan extracts has a potential anti-tumor activity and may be an useful remedy to prevent and/or treat cancer.

In our previous studies, we reported that Selaginella Tamariscina(ST) induced apoptotic cell death in HL-60 cells selectively. The cell viability after treatment with extract of ST was quantified by MTT assay and trypan bleu exclusion method. The results showed that application with ST in HL-60 induced 40% cell death at the concentration of 400 ㎍/ml. The cancericidic effect of Selaginella Tamariscina was mediated by apoptosis. Thus, HL-60 cells exposed to Selaginella Tamariscina displayed the DNA fragmentation ladder and nucleus chromatin condensation characteristic for apoptosis. The enzyme activity of caspase-3 and actived caspase-3 protein were markedly increased HL-60 cells treated with the extract of Selaginella Tamariscina. In addition, the extract of Selaginella Tamariscina induced cleavage of PARP, a known substrate for caspase-3. The expression of BcI-2, anti-apoptotic protein, was decreased by treatment of the aqueous extract of Selaginella Tamariscina in a dose-dependent manner. And the expression of pro-apoptotic Bax protein was increased. In conclusion, our results suggest that the extract of Selaginella Tamariscina may induce the apoptotic death of HL-60 cells via caspase-3, cleavage of PARP protein, depletion of cellular ATP levels and BcI-2 degradation.
