Bradykinin (BK) at 100 nM increased ADP-ribosyl cyclase activity by about 2.5-fold. Application of 300 nM BK to living NGPM1-27 cells decreased NAD+ to 78% of the prestimulation level at 30 s. In contrast, intracellular cADPR concentrations were increased by 2-3-fold during the period from 30 to 120 s after the same treatment. Our results suggest that cADPR is one of the second messengers downstream of B2 BK receptors. © 2006 Federation of European Biochemical Societies., 金沢大学大学院医学系研究科脳細胞分子学}, pages = {4857--4860}, title = {Bradykinin activates ADP-ribosyl cyclase in neuroblastoma cells: Intracellular concentration decrease in NAD and increase in cyclic ADP-ribose}, volume = {580}, year = {2006} }
