Abstract

|
Although the Herba Cirsii is known to posses beneficial health effects, the anti-diabetic effects and the mechanism of action have not been elucidated. In the present study we have shown that Herba Cirsii Extract (HCE) can stimulate glucose uptake in OP9 adipocytes. Unlike insulin, HCE did not stimulate the Ser473 phosphorylation and activation of Akt. The increasing effects of HCE on glucose uptake were inhibited by PD680509 and compound C pretreatment, which means that the glucose uptake effects by HCE were carried out by extracelluar signal-regulated kinase1/2(ERK1/2) and AMP-activated protein kinase (AMPK) activation. Further studies revealed that HCE stimulated glucose transport occurs through a mechanism involving ERK1/2 activation and AMPK activation.
