Ginsenoside Rb1 (GRb1) is a major component of ginseng, which has been shown to
ameliorate hyperglycemia in rodents and in humans with undetermined mechanisms.
Here, we analyzed the molecular mechanisms by which GRb1 reduces the insulin
resistance in high-fat diet (HFD)-induced mouse model for type 2 diabetes (T2D).
HFD was applied for 4 weeks to induce T2D in mice, after which GRb1 was
administrated and the effects on the fasting blood glucose, glucose tolerance and
insulin sensitivity were analyzed. We found that HFD increased fasting blood
glucose, glucose tolerance and reduced insulin sensitivity, which were all
ameliorated by GRb1. GRb1 seemed to reduce the levels of 11?-Hydroxysteroid
dehydrogenase type I (11?-HSD1) in liver and adipose tissue, to exert its
anti-diabetes effects. Overexpression of 11?-HSD1 completely abolished the
effects of GRb1 on HFD-induced increases in fasting blood glucose and glucose
tolerance, and decreases in insulin sensitivity. Together, our data suggest that
GRb1 may increase insulin sensitivity through suppressing 11?-HSD1 in treatment
of T2D.
