Cytotoxic and apoptotic effects of Ferula gummosa Boiss: extract on human breast adenocarcinoma cell line.

Abstract

Ferula gummosa Boiss. is a well-known and valuable medicinal plant in Iran. Research has shown that this plant has several pharmacological properties, including anti-bacterial, anti-cancer and etc. In the present study, we investigated the cytotoxic properties of F. gummosa Boiss. extract in MCF-7 breast adenocarcinoma cells. The cytotoxicity and pro-apoptotic properties of the extract were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) test and propidium iodide (PI) stained cells, respectively. Apoptosis and necrosis were evaluated by annexin V-PI staining. The levels of reactive oxygen species (ROS),malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) was determined to evaluate oxidative stress. The cell migration and the gene expression were assessed by scratch assay and quantitative real-time polymerase chain reaction (q-RT-PCR), respectively. The extract of F. gummosa decreased the viability and cell cycle progression of MCF-7 cells by inducing apoptosis and necrosis, increasing ROS and MDA levels, and decreasing GSH levels and SOD activity. It also lowered the cells' migration capability by enhancing p53 mRNA levels and reducing MMP-9 mRNA expression. F. gummosa exhibited pro-apoptotic, anti-proliferative, and anti-metastatic effects on MCF-7 cells. It is therefore recommended that detailed future research be done on different parts of the plant or its secondary metabolites to find anti-cancer lead compounds.
