Abstract

Objective: The aim of this study was to analyze the effect of avidin treatment on cell viability, proliferation and cyclin D1 expression in colorectal cancer cells HT-29. Methods: Colorectal cancer cell line HT-29 incubated with 50, 100, 150, and 200 μg/mL of avidin concentration during 24, 48, and 72 hours, then the cell viability and proliferation were analyzed. Each avidin concentration was conducted together with HT-29 cell line without avidin treatment as a control group. The cell viability was measured by MTS assay and the proliferation was measured by BrdU (5-bromo-2′-deoxyuridine) cell proliferation assay. According to cell viability and proliferation result, we determined the 100 μg/mL avidin concentration for analyzing mRNA and protein of cyclin D1. Results: We demonstrated that the viability and proliferation of HT-29 cells were significantly decreased in all concentration of avidin treatment compared to control. The cell proliferation showed larger reduction in avidin treatment rather than cell viability. This proves avidin could inhibit proliferation of colorectal cancer cell HT-29 quite well. The expression of cyclin D1, both mRNA and protein, was also significantly decreased after the avidin treatment group compared to control group, it supports the suppression of proliferation result. Conclusion: We concluded that avidin treatment could decrease cell viability and proliferation, accompanied by suppression of cyclin D1 expression in colorectal cells HT-29.
