Serum, bradykinin and vasopressin stimulate release of inositol phosphates from human fibroblasts / L. M. Vicentini, M. L. Villereal. - In: BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS. - ISSN 0006-291X. - 123:2(1984 Sep 17), pp. 663-670.
Abstract:
The mitogens serum, vasopressin and bradykinin stimulate a significant rise in the inositol phosphate content of cultured human fibroblasts within 10 seconds, while serum- and bradykinin-stimulated arachidonic acid release does not occur until after 30 seconds. The release of inositol phosphates is not secondary to a rise in Ca activity since the Ca ionophore ionomycin does not stimulate release of inositol phosphates. Moreover, we show that phospholipase C in human fibroblasts is activated by these mitogens at resting Ca levels since TMB-8, which blocks the mitogen-induced rise in Ca activity, does not affect the serum-stimulated accumulation of inositol phosphates.
