The effect of nitrogen pressure on the grain boundary chemistry of GPS silicon nitride has been investigated. Different pressure values in the Y–Al–Si–Al–O–N system produced silicon nitride specimens with similar microstructures but differe

In order to gain a better understanding on the possible role of retinoic acid (RA) on human GH secretion, we have characterized the expression of its nuclear receptors in somatotropic adenoma cell extracts. By immunoblotting with rabbit polyclonal an

In order to gain a better understanding on the possible role of vitamin A (VA) and retinoic acid (RA) on human growth hormone (GH) secretion, we used the physiological model of pituitary cells perifusion. In perifused cells from pituitary somatotropi

Integrins are heterodimeric transmembrane molecules that mediate cell-cell and cell-substratum adhesion. Because alterations in the adhesive properties of tumor cells influence tumor growth and progression, the distribution of different alpha and bet

Several regulatory neurotactors, classically associated with the hypothalamus, may be synthesized in the anterior pituitary (AP). Dopamine (DA) is the main prolactin-inhibiting factor. Its de novo synthesis in the normal AP has not been proved, altho

Arguments favor an in situ synthesis of GH-releasing hormone (GHRH) in the normal and tumoral human anterior pituitary. These tissues may express human (h) GHRH messenger RNA, contain hGHRH-(1-44)-NH2, and secrete in vitro an immunoreactive form (ir-

We have previously shown that the somatostatin (SRIH) precursor (pro-SRIH) and SRIH are present in the normal human pituitary, whereas mature SRIH is never detected in GH-secreting adenomas associated with high plasma GH levels, and pro-SRIH is absen

Protein kinase-C (PKC) is a ubiquitous eukaryotic kinase that plays a key role in transmembrane signaling and influences important cellular processes, such as proliferation. Increases in its activity and expression have been demonstrated in adenomato

Normal and tumoral human pituitaries release in vitro SRIH and contain messenger RNAs encoding preproSRIH. In the present study, we document the presence and characterization of the SRIH precursor in both human normal pituitaries and in GH-secreting
