A polysaccharide with a triple helix structure from Agaricus bisporus: Characterization and anti-colon cancer activity.
AI Summary
Key Findings
Abstract
In this study, A polysaccharide WAAP-2 (121 kDa) with a triple-helical structure was isolated and purified from Agaricus bisporus for the first time. The physicochemical properties, structural characteristics and anti-colon cancer activity were preliminarily investigated. The primary structure indicated that WAAP-2 was composed of mannose, glucose and galactose and determined the position of the linkage between monosaccharide residues. The advanced structure revealed that WAAP-2 has a triple helix and tangled chain conformation. In the anti-colon cancer activity investigation, WAAP-2 exerted an apoptosis-inducing effect by causing HT-29 cell cycle arrest in S phase. WAAP-2 promoted HT-29 cell apoptosis by up-regulating the expression of Caspase-3 and Bax proteins while down-regulating the expression of Bcl-2 protein. Besides, WAAP-2 could inhibit the migration and invasion of colorectal cancer cells by inducing E-cadherin expression and inhibiting Vimentin expression to affect epithelial mesenchymal transition. This paper is of importance for the application of WAAP-2, a triple-helical structural polysaccharide from Agaricus bisporus, to low-toxicity anti-colon cancer drugs.
