<unk>  hormones increase (or, in case of inhibitory factors, decrease) the intracellular concentration of calcium (Ca2+), resulting in vesicle fusion of the respective primary hormone. For GnRH, TRH and GHRH the increase in Ca2+ is achieved by the<unk>  hormone coupling and activating G protein coupled receptors coupled to the Gq alpha subunit, activating the IP3/DAG pathway to increase Ca2+. For GHRH, however, this is a minor pathway, the main one being the cAMP dependent pathway.
