Abstract
Berberine (BBR) has been reported in several studies in cell and animal models. However, the mechanism of actions is not fully understood. The present study was therefore aimed to explore the effects of berberine on insulin sensitivity and kidney damage in a high fat diet rat model. Impaired glucose tolerance rats induced by injection of berberine while fed with high fat laboratory chow. After rats were treated for 4 weeks, OGTT and IPITT were determined. Mass and PAS were used to study the kidney tissue. ELISA was used to detect the protein concentration of CRP and TNF-α. Western blot was used to detect the proteins adiponectin, adipoR1, adipoR2 and p-AMPK expression level. These encouraging findings suggest that berberine has excellent pharmacological potential to prevent kidney damage.
