Abstract excerpt
Cyclic nucleotide phosphodiesterases (PDEs) were investigated in cultured bovine aortic endothelial cells having two phenotypes, cobblestone and spindle, representing, respectively, the resting and angiogenic phenotypes in vivo. Spindle cell homogenates displayed higher hydrolytic activities towards cAMP (52%) and cGMP (10-fold). These increases were due to: (1) increased number of spindle PDE isozymes in the...
