Abstract:
:We have used human neuroblastoma NB-OK1 cells to investigate the regulation of neurite outgrowth. Carbachol suppressed forskolin-stimulated neurite outgrowth in NB-OK1 cells although forskolin-stimulated cAMP levels were enhanced. The dose-response curve for this suppression was very similar to that for stimulation of inositol monophosphate (IP1) formation and for stimulation of the initial rise of [Ca2+]i elicited by carbachol. Carbachol-mediated changes in neurite outgrowth, IP1 formation and [Ca2+]i displayed high sensitivity for pirenzepine but low sensitivity for AF-DX116. Inhibition of intracellular calcium release with TMB-8 prevented the suppressive effect of carbachol on forskolin-stimulated neurite outgrowth. Hence we describe for the first time a relationship between neurite outgrowth and inositol triphosphate-triggered calcium release mediated by carbachol in the human neuron-derived cell line.
