Abstract

Inulin, a naturally occurring, functional food ingredient found in various edible plants, has been reported to exert potential health benefits, including decreased risk of colonic diseases, non-insulin-dependent diabetes, obesity, osteoporosis, and cancer. However, the mechanism of the antidiabetic activity of inulin has not yet been elucidated. In this study, we showed that inulin increased the uptake of glucose in C2C12 myotubes, which was associated with both AMP-activated protein kinase (AMPK) and phosphatidylinositol 3-kinase (PI3-K) signaling pathways, but both of these pathways appeared to transmit their signals in an independent manner. Moreover, we found that inulin was able to increase the uptake of glucose in C2C12 myotubes in which insulin resistance was induced by exposing cells to high glucose concentrations. The identical effects of inulin were also observed in HepG2 hepatoma cells. Collectively, we report the antidiabetic activity of inulin and further demonstrate for the first time that such activity is associated with AMPK and PI3-K activation. © Mary Ann Liebert, Inc.
