Effect of Hydralcoholic Extract of Dafneh on Expressin Level of MAPK8 and PTK2 Genes and Cell Viability of Ovarian Cancercell Lines (A2870S)

Abstract

Introduction: Ovarian cancer, as an aggressive epithelial tumor, remains one of the leading causes of cancer-related mortality in women. Regarding to the side effects of chemical drugs, medicinal plants, according to their unique properties such as cheapness, naturalness and availability, and without any significant side effects, medicinal plants have recently been considered in the prevention of diseases. In this laboratory research, the cytotoxic effect of hydroalkolic extract of Daphne mucronata Royle on cell viability of A2780 cancer cell and the expression of MAPK8 and PTK2 genes in the cells treated with the Ephedra plant extract during three-time interval 24,48 and 72 hours after treatment were investigated. Methods: The inhibitory effect of hydroalcholic extact of D. mucronato on targeted cells was done using MTTassay then, expression level of MAPK8 and PTK2 genes in cells treated with plant extract were investigated using qRT-PCR method. Data analyses were done using GraphPad prism software. Results: Regarding to the results of cell viability, IC50 rate for 24, 48 and 72h after treatment were determined as 105.40, 85.98 and 81.38µg/mL, respectively. Expression analysis of tested genes showed that hydroalcoholic plant extract of D. mucronato had not significant effect on expression of targeted genes (Pvalue≤0.05) so that there was no significant difference on their expression level compared to the control. Conclusion: According to the results, it can be concluded that D. mucronato extract had a significant inhibitory effect on treated A2870s cancer cells, but it was not able to change the expression level of genes involved in anticancer activities and its molecular pathways. The use of bio-markers and other gene pathways is suggested for additional studies.
