Molecular mechanisms of the anticancer action of fustin isolated from Scop. in MDA-MB-231 triple-negative breast cancer cell line.

The aim of the present work was to investigate some of the molecular mechanisms and targets of the anticancer action of the bioflavonoid fustin isolated from the heartwood of Scop. in the triple-negative breast cancer cell line MDA-MB-231. For this purpose, we applied fluorescence microscopy analysis to evaluate apoptosis, necrosis, and mitochondrial integrity, wound healing assay to study fustin antimigratory potential and quantitative reverse transcription-polymerase chain reaction to analyze the expression of genes associated with cell cycle control, programmed cell death, metastasis, and epigenetic alterations.

Scop. induces cell cycle arrest, apoptosis, genotoxic effects, thermodynamic and epigenetic events in MCF7 breast cancer cells.

Current plant-derived anticancer therapeutics aim to reach higher effectiveness, to potentiate chemosensitivity and minimize the toxic side effects compared to conventional chemotherapy. Scop. is a herb with high pharmacological potential, widely applied in traditional phytotherapy.
