Pattern of [³H]-ATP catabolism in the medium of endothelial cell cultures after 45 min stimulation by shear stress. The bathing medium was incubated with 100 nM [³H]-ATP with subsequent TLC analysis of both [³H]-ATP decrease and formation of its ³H-labeled derivatives (ADP, AMP and adenosine). The relative amounts of nucleotides and adenosine are expressed on the ordinate axis as percentage of the initial concentration of [³H]-ATP. (n=2).
