Ca2+ influx through voltage-gated Ca2+ channels (VGCCs) plays a key role in GH secretion. In this review, we summarize the current state of knowledge regarding the physiology and molecular machinery of VGCCs in pituitary somatotrophs. We next discuss

Voltage-gated calcium channels (VGCCs) are osmosensitive. The hypothesis that this property of VGCCs stems from their susceptibility to alterations in the mechanical properties of the bilayer was tested on VGCCs in pituitary cells using cone-shaped l

The coupling of voltage-gated Ca2+ channel (VGCC) to exocytotic proteins suggests a regulatory function for the channel in depolarization-evoked exocytosis. To explore this possibility we have examined catecholamine secretion in PC12 and chromaffin c

Using FM1-43 fluorescence, we have optically detected single exocytic and endocytic events in rat pituitary lactotrophs. About fifty discrete fluorescent spots abruptly appear around the entire surface of a cell bathed in FM1-43 and high-potassium sa

1. The sensitivity of voltage-gated calcium currents to hyperosmotic media containing mannitol or sucrose (373-723 mOsm) and to the dihydropyridine (DHP) calcium channel agonist Bay K 8644 was examined in enriched populations of rat anterior pituitar

Increased extracellular osmolarity ([Os]e) suppresses stimulated hormone secretion from anterior pituitary cells. Ca2+ influx may mediate this effect. We show that increase in [Os]e (by 18–125%) differentially suppresses L-type and T-type Ca2+ chan

Several lines of evidence suggest that dopamine acts as a neurotransmitter that inhibits both hormone secretion and electrical activity in pituitary intermediate cells (melanotrophs). In this study we examined the effects of exogenously applied dopam
