Dopamine (DA) is known to inhibit basal and hormone TRH- or angiotensin II (AngII)-stimulated PRL secretion and inositol phosphate accumulation in rat pituitary cells in primary culture. This inhibition persists when cells are incubated in a calcium-

The in vivo and in vitro inhibitory effects of a somatostatin (SRIH) analog, octreotide, upon TSH, alpha-subunit, GH, and PRL have been studied, as well as SRIH receptors and their coupling to adenylate cyclase, in nine TSH-secreting pituitary adenom

Bioactivity-guided purification of a crude alkaloid extract of Psychotria oleoides has afforded a new alkaloid, psycholeine [1], together with quadrigemine C [2], a tetrameric pyrrolidinoindoline compound of unknown stereochemistry. A comparison stud

Angiotensin II (AII) and thyreoliberin (TRH) have recently been shown to stimulate intracellular cAMP formation in rat lactotroph cells, in addition to their already documented coupling to phospholipase C. The effect on intracellular cAMP is unaffect

In the accompanying study, we reported the effects of inhibitors of arachidonic acid metabolism on the regulation of prolactin, growth hormone (GH) and luteinizing hormone secretion by male hemipituitaries. The present work extends these investigatio

When applied to rat anterior pituitary cells, angiotensin-II (AII) exerted two opposite effects on adenylate cyclase (AC) activity: a pertussis toxin (PTX)-sensitive inhibition of the enzyme with a maximal effect of -42 +/- 2% in crude cell membrane

The effects of psycholeine, a plant alkaloid, were investigated on binding of radiolabelled somatostatin ([125I]N-Tyr-SRIF) and on somatostatin (SRIF)-induced inhibition of adenylate cyclase activity and growth hormone (GH) secretion by rat anterior

Incubation of dispersed adenohypophyseal cells from intact male rats with Neuropeptide Y (NPY) or Peptide YY (YY) at 21 degrees C increased maximal 125I LHRHa binding (Bmax) by about 50%. In presence of 10(-7) M NPY, Bmax calculated from saturation i

GH4C1 cells, a clonal cell line from a rat pituitary tumor, have been widely used as a model to study the regulation of prolactin secretion. These cells, however, do not express dopamine D2 receptors and are therefore not suitable for exploring mecha
