In Vitro Evaluation of Apoptotic Induction of Butyric Acid Derivatives in Colorectal Carcinoma Cells

Background/Aim: Butyric acid, a short chain fatty acid, plays an important role in the prevention of colon cancer. The aim of this study was to analyze the growth inhibitory and apoptotic effect of butyric acid derivatives in colorectal cancer cells. Materials and Methods: Human colorectal carcinoma HCT116 cells, were treated with the IC50 concentration of sodium butyrate, indole-3-butyric acid, tributyrin and 2-aminon-butyric acid. Comet assay, caspase-3 assay and cell-cycle analysis were used to analyze apoptosis. Results: Tributyrin and indole-3-butyric acid showed the least IC50 values at 24 h incubation. Butyric acid derivatives significantly activated caspase-3 activity compared with the control. Additionally, indole-3-butyric acid and tributyrin caused G(0)/G(1) and G(2)/M phase arrest. Conclusion: Butyric acid derivatives effectively induced apoptosis in HCT116 cells.
