WebSuch activation was enhanced if cAMP levels were elevated in these cells by treatment with either the adenylate cyclase activator forskolin or cell-permeant cAMP analogues. However, treatment of cells with glucagon, despite this hormone-activating adenylate cyclase, led to a blockade in the ability of insulin to activate the PPM-PDE ( Heyworth et … WebForskolin would appear to activate adenylate cyclase through a unique mechanism involving both direct activation of the enzyme and facilitation or potentiation of the modulation of enzyme activity by receptors or the guanyl nucleotide-binding subunit, or both.
