Title

The p53 Modulated Cytotoxicity of Ophiocoma scolopendrina Polysaccharide Against Resistance Ovarian Cancer Cells

Pages

  208-214

Abstract

 Background: Marine environment is a valuable source of bioactive compounds with variable medicinal properties. Previously, it was shown that Ophiocoma erinaceus ex-tracted polysaccharide has prominent cytotoxic effect on HeLa human cervical cancer cells. In the present study, the anti-cancer properties of polysaccharide extracted from Ophiocoma scolopendrina (O. scolopendrina) were examined in comparison with Paclitaxel as a conventional drug against resistant ovarian cancer; also, its related mechanism against A2780cp ovarian cancer cells was investigated. Methods: The A2780cp cancer cells and NIH3T3 normal cells were cultured and treat-ed with different concentrations of polysaccharide extracted from O. scolopendrina for 24 hr and 48 hr. Then, cell toxicity was studied by MTT assay, morphology of cells was observed under inverted microscopy and the type of induced cancer cell death was assessed by annexin V-FITC, propodium iodide and acridine orange staining. Finally, the Apoptosis pathway was determined by measurement of caspase-3 and caspase-9 activity and assessment of p53 and Bcl-2. The statistical analysis was performed by SPSS software, one way ANOVA and p<0. 05 was considered significant. Results: Our observations from MTT assay and morphological assessment exhibited that O. scolopendrina isolated polysaccharide inhibited proliferation of ovarian cancer cells with IC50 of 35 μ g/ml, while Paclitaxel suppressed tumor cell growth with IC50=10 μ g/ml. In contrast, MTT observations revealed low cytotoxicity of these chemothera-peutic agents against NIH3T3 normal cells. Also, the analysis correlated with induced cell death elucidated that concurrent treatment of polysaccharide plus Paclitaxel had a further anti-cancer effect against A2780cp cells mainly through restoration of p53 and mitochondrial Apoptosis cell death induction. Conclusion: Taken together, our research supports the finding that application of pol-ysaccharide extracted from O. scolopendrina can be considered a promising marine chemotherapeutic approach for advancing efficacy of Paclitaxel in treatment of re-sistant ovarian cancer. Additional in vivo experiments are required to elucidate the role of brittle star polysaccharides in animal and clinical trials.
