  • Description: <jats:p><jats:bold>Abstract: </jats:bold> Rat PC‐12 pheochromocytoma cells respond to stimulation with bradykinin, angiotensin II, and carbachol with an increased formation of labeled inositol phosphates after preincubation of the cells with [<jats:sup>3</jats:sup>H]inositol. Li<jats:sup>+</jats:sup> potentiates greatly the agonist‐induced increase in amount of nositol mono‐, bis‐, and trisphosphate but not the increase in amount of inositol tetrakisphosphate. Separation of the isomers of inositol trisphosphate shows that the lithium‐induced increase in amount of inositol trisphosphate is due to potentiation evoked by lithium of the accumulation of inositol‐1,3,4‐trisphosphate.</jats:p>
