The purpose of this study was to investigate the anti-cancer effects of Sophorae Radix (SR) and doxorubicin (DOX) in human gastric and colorectal adenocarcinoma cells. We used the human gastric and colorectal adenocarcinoma cell lines (MKN-45 and WIDR cells, respectively). We examined cell death by using the MTT(3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay and the caspase 3 assay with SR. To examine the inhibitory effects of SR, we performed a cell cycle (sub G1) analysis for the MKN-45 and WIDR cells after three days with SR. The reversibility of SR was examined for one-day to five-day treatments with SR. SR inhibited the growth of MKN-45 and WIDR cells in a dosedependent manner. Also, we showed that SR induced apoptosis in MKN-45 and WIDR cells by using the MTT assay, the caspase 3 assay and the sub-G1 analysis. SR combined with DOX markedly inhibited the growth of MKN-45 and WIDR cells compared to SR or DOX alone. After 3 days of treating MKN-45 and WIDR cells with SR, the fraction of cells in the sub-G1 phase was much higher than that of the control group. Our findings provide insights into unraveling the effects of SR on human gastric and colorectal adenocarcinoma cells and into developing therapeutic agents for use against gastric and colorectal adenocarcinomas.

To investigate the protective effect of Sophorae Radix (SR) on the damage by pulmonary vascular endothelial cells by xanthine oxidase (XO)/hypoxanthine (HX)-induced oxygen tree radical, Neutral Red (NR) and c-fos immunopositive cell assay were used. The results were obtained as follows ; The viability of vascular endothelial cells treated with XO/HX was decreased. And c-fos immunopositive cells represented a maximal increase in group treated with XO/HX for 2 hour in pulmonary vasvular endothelial cells. But pretreated groups with SR extracts were not inhibited the increase of c-fos immunopositive cells by XO/HX in a dose-dependent manner. These results show that XO/HX elicits toxic effects in cultured pulmonary vascular endothelial cells, and suggest that SR extract is very effective in the prevention of XO/HX-induced increase of c-fos immunopositive cells.

Traditional herbal medicines are being increasingly used worldwide to treat cancer. Radix Sophorae Flavescentis (RSF) is a Chinese herb, which has numerous pharmacological properties, including anti-tumour effects. In this study, we investigated the mechanisms underlying RSF-induced apoptosis in human gastric cancer cells (AGS cells). We found that RSF treatment (20-200 ㎍/ml) inhibited the proliferation of AGS cells and increased the sub-G1 phase ratio. RSF-induced cell death was associated with the downregulation of BCl-2 and upregulation of Bax. In addition to increasing the expression levels of apoptosis-mediating surface antigen FAS and Fas ligand, RSF also activated caspase-3; however, mitogen-activated protein kinase appeared to inhibit RSF-induced cell death. RSF also led to an increased production of reactive oxygen species. Based on these results, we propose that RSF could be a potential therapeutic agent for gastric cancer.

To test the cytoprotective effect of sophorae radix (SR) against hydrogen peroxide (H₂O₂)-induced cytotoxicity, we investigated the cell viability using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay in the presence of methylene chloride, n-butanol, ethyl acetate and water soluble fraction of SR water extracts in H9c2 cells. These results were obtained as followed; H₂O₂ decreased the cell viability of H9c2 cells in a dose dependent manner. Cells pretreated with SR water extracts were protected the H₂O₂-induced decrease of viability in H9c2 cells. Among organic solvents fractions of SR water extracts, ethyl acetate soluble fractions of SR protected the decrease of viability induced by H₂O₂ in H9c2 cells. These results suggest that ethyl acetate soluble fractions of SR water extracts is effective in the prevention of H₂O₂-induced cytotoxicity.

To test the cytoprotective effect of sophorae radix (SR) against hydrogen peroxide (H₂O₂)-induced cytotoxicity, we investigated the cell viability using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay in the presence of ethyl acetate subfractions of SR water extracts In H9c2 cells. And to clarify the cytoprotective mechanism of SR extracts, we evaluated the cellular glutathione (GSH) contents in the presence of subfraction 1, 2, 3, and 4 of SR ethyl acetate soluble fractions. Among 1 -12 subfractions of SR ethyl acetate soluble fractions, 1, 2, 3 and 4 subfractions have an efficacy inhibiting the cytotoxicity induced by H₂O₂ in H9c2 cells. Also, the protective effects of 1, 2, 3 and 4 subfractions of SR ethyl acetate soluble fractions resulted from the anti-oxidant effects. These results suggest that ethyl acetate soluble fractions of SR water extracts is effective in the prevention of H₂O₂-induced cytotoxicity and 1, 2, 3 and 4 subfraction of ethyl acetate soluble fractions possess the anti-oxidant component.

Sophorae Radix (SFR) is known as a therapeutic drug that has been used in Oriental traditional medicine for the treatment of skin and mucosal ulcers, gastrointestinal hemorrhage, diarrhea, inflammation and arrhythmia. In the present study, we examined the effects of the aqueous extract of SFR on anti-inflammation, anti-allergic and anti-oxidant effect in various cell lines; they include mouse lung fibroblast cells (hFCs), human mast cells (HMC-1), human monocytic cells (THP-1), and RAW 264.7 cells. Treatment with SFR extract at a concentration of 250 ${\mu}g$/ml for 24h showed no significant decrease in the survival rate of the hFCs. SFR decreased the mRNA expression of IL-8, TNF-$\alpha$, and IL-6 in HMC-1 cells. SFR extract treatment significantly inhi-bited the protein expression of IL-6 and, IL-8 induced by mite in THP-1 cells and it also did MCP-1 expression. We examined the alternation of histamine release in HMC-1 cells for investigating anti-allergic effect of SFR. Histamine secretion decreased after the treatment with SFR. In addition, SFR extract treatment at a concentration of 10 ${\mu}g$/ml, 100 ${\mu}g$ /ml, and 200 ${\mu}g$/ml lowered the $\beta$-hexosaminidase to 10.3%, 21.7%, and 50.8%, respectively. IC50 of SFR extract in RBL-2H3 cells was 196.85 ${\mu}g$/ml. Both activity of NF-$\kappa$B promoter in RBL-2H3 cells significantly diminished after the dose-dependent treatment of SFR. Therefore, our results indicate that SFR has anti-inflammatory and it may be useful for treating allergic diseases such as atopic dermatitis.
