Stimulation of adenylate cyclase by Ca2+ and calmodulin in rat islets of langerhans: explanation for the glucose-induced increase in cyclic AMP levels.

abstract：:The vascular endothelial growth factor (VEGF) family of cytokines are important regulators of angiogenesis that have emerged as important targets for the treatment of obesity. While serum VEGF levels rise during obesity, recent studies using genetic models provide conflicting evidence as to whether VEGF prevents or ac...
