摘要

Endogenous hydrogen sulfide (H2S) regulates multiple physiological and pathological processes in colon epithelial tissues. The current study investigated the role of cystathionine β-synthase (CBS), a major producer of H2S in colon epithelial cells, in the pathogenesis of UC-related intestinal barrier injury. The expression and DNA methylation level of CBS were investigated in inflamed and non-inflamed colon tissues collected from UC patients, and the effect of decreased CBS levels on Caco-2 monolayer barrier injury and altered status of tight junctions elicited by TNF/IFN was determined.
