Abstract

H(2)S has been proposed as physiological important molecule. It is considered as first endogenous gaseous K(+) channel opener. K(+) ATP channel activity is mainly responsible for insulin secretion. K(+)ATP channel opening of β cells leads to inhibition of insulin secretion and channels closing leads to secretion. H2S is the gaseous K(+) ATP channel opener but it does not have channel specificity. So, H(2)S may have some effect on insulin secretion. H(2)S is high in Zuker diabetic fatty rats. That means H(2)S is high in insulin resistance condition. We tried to find out the role of H(2)S in insulin secretion and in development of insulin resistance. From the result of our study, H(2)S have K(+) ATP channel opening activity on β cells. H(2)S does not have any role in the development of insulin resistance. Decrease in insulin level in Zuker diabetic rat and streptozotocin-induced diabetic rat is due to high H(2)S level.

Keywords: Glucose; K+ ATP channel; hydrogen sulfide; insulin.
