Cytotoxic and Apoptotic Effects of Ferulic Acid on Renal Carcinoma Cell Line (ACHN)

Background: Polyphenolic compounds have anti-proliferative effects and can trigger apoptosis in cancer cells. Ferulic acid is excessively found in various herbal products and fruits. Ferulic acid plays a role in the treatment of neurodegenerative diseases, cancer, diabetes, cardiovascular disease, inflammation, and bacterial and viral infections. Objectives: The purpose of this study was to evaluate the anticancer effect of ferulic acid on renal carcinoma cells (ACHN). Methods: To assess the anti-proliferative effect of ferulic acid, the renal carcinoma cell line (ACHN) was treated with different ferulic acid concentrations (10, 20, 40, 80, and 160 M) for 24, 48, and 72 hours. Cell viability was measured using the MTT assay. The apoptosis of cancer cells was evaluated by flow cytometry and real-time PCR. Results: The IC50 of ferulic acid againstACHNcells was determined to be 30Mat 72 hours with theMTT assay. The treatment of cells with ferulic acid concentrations of 30 and 60Mcaused a significant increase in the apoptosis index. The Bcl-2 gene expression level was significantly lower in the treated group than in the control group, and the Bax gene expression level was significantly higher in the treated group than in the control group (P < 0.001). Conclusions: The results of this study showed the apoptotic activity of ferulic acid against ACHN cells. These results can be helpful in the better understanding of the anticancer mechanism of ferulic acid, suggesting this substance as an alternative drug or in combination with conventional chemical treatments for cancer treatment.
