Research Abstract

The aim of this study is to characterize the cytoprotective effects of a gasotransmitter hydrogen sulfide(H_2S) and to elucidate its molecular mechanism on insulin-secreting cells. H_2S, which is endogenously produced in an inducible manner by H_2S-producing enzyme CSE, protects insulin-secreting cells against oxidative stress(occur under diabetic condition) via an anti-oxidative mechanism.
