Some pharmacological properties of the cremaster muscle of the guinea-pig.

abstract：BACKGROUND AND PURPOSE:Quercetin lowers plasma glucose, normalizes glucose tolerance tests and preserves pancreatic β-cell integrity in diabetic rats. However, its mechanism of action has never been explored in insulin-secreting β-cells. Using the INS-1 β-cell line, the effects of quercetin were determined on glucose- ...
