1 Previous studies determined that direct activation of protein kinase C (PKC) with phorbol esters increases the number of angiotensin II (ANG II)-specific binding sites in neuronal cultures prepared from the hypothalamus and brain stem of 1-day-old rats. Phorbol Esters angiotensinogen Rattus norvegicus
2 Previous studies determined that direct activation of protein kinase C (PKC) with phorbol esters increases the number of angiotensin II (ANG II)-specific binding sites in neuronal cultures prepared from the hypothalamus and brain stem of 1-day-old rats. Phorbol Esters angiotensinogen Rattus norvegicus
3 In the present study we have examined whether stimulation of IP hydrolysis, and presumably activation of PKC, can mimic the actions of phorbol esters on ANG II-specific binding. Phorbol Esters angiotensinogen Rattus norvegicus
4 Incubation of neuronal cultures with norepinephrine (NE) at concentrations (greater than 5 microM) and for times (15-60 min) that cause large increases in IP hydrolysis caused increases in the number of ANG II-specific binding sites, mimicking the actions of phorbol esters. Phorbol Esters angiotensinogen Rattus norvegicus
