    Abnormal transduction of dopamine signal in human nonfunctioning pituitary adenomas

    It is well established that dopamine (DA) plays an important role in inhibiting anterior pituitary function. DA receptors present in the pituitary show the pharmacological and biochemical characteristics of th...

    In vitro detection of glycoprotein production and secretion by human nonfunctioning pituitary adenomas

    This study, carried out on 9 nonfunctioning pituitary adenomas, was undertaken in order to evaluate the ability of these tumors to synthesize and release gonadotropins and/or free a-subunit (a-SU) of glycoprot...

    TRH raises cytosolic Ca2+ in human adenomatous lactotrophs

    The effect of TRH on cytosolic free calcium concentrations, [Ca2+]i, was evaluated on cell suspensions obtained from 6 human PRL secreting pituitary adenomas. In these cells resting [Ca2+]i levels were variable (...

    Alpha-1-Adrenergic Stimulation of Cytosolic Ca2+ Concentration and Growth Hormone (GH) in Rat Somatotrophs

    It is well established that the α-adrenergic system plays a primary role in the regulation of growth hormone (GH) release in humans and animals (1–3). As far as the site of action of α-adrenergic agents is con...
