Inhibitory Effect of Chondroitin Sulfate from Sturgeon Bone on Colorectal Cancer Cells
摘要
Abstract
Objective:This study is aimed to investigate the inhibitory effect of chondroitin sulfate from sturgeon bone on the proliferation of colorectal cancer cells and to elucidate the underlying mechanism.Methods:Three representative colorectal cancer cells (Caco-2,HCT-116,and SW480) were used in this study.Cell growth and proliferation was tested by cell counting kit-8 (CCK-8) method.Colorectal cancer cell line HCT-116 was used to further investigate the pro-apoptotic ability of sturgeon chondroitin sulfate.Cell cycle and apoptosis were determined by flow cytometry.Cell morphology was observed after cell staining.Apoptosis was evaluated by caspase-3 activity.Our study indicated that sturgeon chondroitin sulfate significantly inhibit the cell proliferation of Caco-2,HCT-116 and SW480 cells with a percentage suppression of 70.94%,90.00% and 75.00%,respectively.After sturgeon chondroitin sulfate treatment,the G1/G0 phase increased to 88.56% and the S phase declined to 4.47%.Meanwhile,sturgeon chondroitin sulfate-treated cells exhibited morphological changes,nuclear pyknosis and cell fragmentation,and significantly increased apoptotic enzyme activity (1 645 IU/μg) with an apoptosis rate of 63.73%.Sturgeon chondroitin sulfate showed potential anticancer activity,which will make it a new functional food ingredient.关键词
