Abstract

BACKGROUND: Zingiber officinale Rosc. is estrogenic and thus can be developed as an anti-osteoporosis. Difructose anhydride III (DFA III), possesses anti-osteoporosis potencies. This study aimed to investigate the anti-osteoporosis activity of ginger rhizome water extract (GE) and DFA III from dahlia tubers in ovariectomized (OVX) rat models and to determine their anti-osteoclastogenic effect in vitro.METHODS: This study was conducted using 25 female rats. Blood sampling was carried out at the beginning and end of treatments. Femur bones were isolated after daily 14-day treatments, measured for density, and processed for histological staining. RAW 264.7 cells were induced by osteoclast differentiation factor. A cell viability assay was employed to determine the cytotoxicity of DFA III and GE. The inhibition of osteoclastogenesis was investigated by tartrate-resistant acid phosphatase staining.RESULTS: All groups showed no difference in body weight elevation and serum lipid profiles. The GE and DFA III caused no effect on bone density. However, the GE or DFA III groups showed higher osteoblast numbers compared with the control groups. A significantly less osteoclast was found in the GE+DFA III group. The GE and DFA III showed no toxicity on RAW 264.7 cells. GE showed strong inhibitory effects on the post stimulation osteoclastogenesis model. The combination of GE and DFA III was synergistic in reducing the osteoclastogenesis confluency in RAW 264.7 cells.CONCLUSION: The data support our hypothesis that GE and DFA III can decrease the risk of osteoporosis by osteoclastogenesis inhibition.KEYWORDS: Dahlia spp., estrogenic, ginger, osteoclast, osteoporosis, ovariectomy, RAW 264.7 cell

Abstract

BACKGROUND: The presence of adverse side effects limits the use of doxorubicin (Dox) despite its cost-effectiveness compared to other chemotherapeutic agents. Brazilein (Be), the major compound of Caesalpinia sappan, performs co-chemotherapeutic potency in several cancer cell lines. This study evaluates the chemosensitizing effects of Be to Dox on colon cancer cell line, WiDr.METHODS: The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was conducted to evaluate the cytotoxic effect of Be and its combination with Dox. The synergistic effect of Be and Dox was examined by using the Combination index (CI) parameter. Cell cycle and apoptosis profiles were done using flow cytometry with propidium iodide (PI)/RNase and Annexin V staining, respectively.RESULTS: The combination of Dox and Be at half of IC50 on WiDr cells showed a synergistic effect with a combination index of 0.4. Analysis of the cell cycle revealed that the combination caused cell cycle termination at the S and G2/M phase. This finding corresponded with the data that single treatment of Dox and Be induced cell cycle arrest at the different phases, namely S and G2/M phase, respectively. However, the combination treatment for 24 hours did not induce apoptosis. This combination should be further clarified as there was a possibility that many cells may underwent permanently arrest that halts to proceed apoptosis.CONCLUSION: Our findings suggested that Be synergizes with Dox to suppress the growth of WiDr cells via cell cycle arrest, hence, Be is potential to be developed as a co-chemotherapeutic agent.
