Outline of Final Research Achievements |
The KATP channel plays an essential role in glucose-induced insulin secretion from pancreatic beta-cells. KATP channels are also found in GIP-secreting K-cells, but, the physiological role of the KATP channels in K-cells is not known. We have clarified that (1)these KATP channels do not participate in GIP secretion under normoglycemic condition, (2)but contribute to glucose-induced GIP secretion under the streptozotocin-induced diabetic state, (3)fructose does not significantly stimulate GIP secretion in the normal state, but significantly enhances the GIP secretion in the streptozotocin-induced diabetic state, However, these KATP channels do not contribute to fructose-induced GIP secretion under hyperglycemic condition, and (4)while the expression levels of sodium-glucose co-transporter 1(SGLT1) mRNA in duodenum are increased by chronic loading of high-carbohydrate diet in mice, the KATP channels do not participate in this.
