The Effects of Orcinol on Proliferation and Apoptosis of SW480 Human Colorectal Cancer Cells

Abstract

Objective: Colorectal cancer is a rapidly increasing disease worldwide, and almost half of the diagnosed patients die from this disease each year. The methods used in the treatment of colorectal cancer, including traditional treatment methods such as surgery, radiotherapy and current chemotherapy options, have low effectiveness and have many side effects. Because of all these problems, the importance of developing new agents for the treatment of colorectal cancer is increasing. Orsinol is a secondary metabolite isolated from lichens, and there are findings regarding the antioxidant, antimicrobial and antidepressant activity of the compound. In recent years, research on the anticancer activity of the compound has also started to take place in the literature. In this study, it was aimed to investigate the efficacy of orcinol on cell proliferation and apoptosis in human SW480 colorectal cancer cells.
 Material and Method: Within the scope of the study, SW480 human colorectal cancer cells were used and cultured in DMEM medium. Orcinol was dissolved with dimethylsulfoxide to prepare a stock solution and applied to the cells in a concentration range of 1-25 mM. The effect of orcinol on cell viability was determined by MTT test. The apoptotic activity of the compound was evaluated with Annexin V binding assay using the Muse Cell Analyzer.
 Result and Discussion: The results of MTT analysis showed that orcinol significantly decreased cell viability at 5 mM and above (p
