Evaluation of cytotoxic, anti-oxidant, and apoptotic effects of Dysphania botrys extract on B16F10 and MCF-7 cell lines.

Objectives: against B16F10 and MCF-7 cell lines. Materials and Methods: The anti-oxidant activities of fractions were measured using FRAP, DPPH, and β-carotene assays. The cytotoxicity of extracts and the intracellular ROS content were assessed using resazurin and DCFH-DA assays, respectively. A flow cytometry assay using PI staining was performed to measure the apoptotic activity of the fractions. Total phenolic and flavonoid content was determined using spectrophotometric methods. Results: exhibited the highest anti-oxidant activity in FRAP, DPPH, and β-carotene assays, which also showed the highest amount of phenolic and flavonoid content compared to the MeOH extract and PE fraction. Cell viability and intracellular ROS content were significantly decreased following the treatment of B16F10 and MCF-7 cells with 100 and 200 µg/ml DCM and PE fractions. Treatment with 200 µg/ml DCM and PE fractions increased apoptosis in B16F10 cells. Conclusion: and their protective mechanisms.
