Regulation of -Cell Mass by Hormones and Growth Factors
Substantial new information has accumulated on molecular mechanisms of pancreas development, regulation of -cell gene expression, and the role of growth factors in the differentiation, growth, and regeneration of -cells. The present review focuses on some recent studies on the mechanism of action of cytokines such as growth hormone (GH) and prolactin (PRL) in -cell proliferation and gene expres...
متن کاملGastrointestinal hormones and the regulation of β-cell mass.
Type 2 diabetes occurs due to a relative deficit in β-cell mass or function. Glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), cholecystokinin (CCK), and gastrin are gastrointestinal hormones that are secreted in response to nutrient intake, regulating digestion, insulin secretion, satiety, and β-cell mass. In this review, we focus upon β-cell mass regulation....
متن کاملPhotoperiodic regulation of insect and molluscan hormones.
The universal occurrence of photoperiodism in insects is due to convergentevolution. The neuroendocrine system, playing the central role in the photoperiodicresponse, gives diversified terminal expressions of adaptive significance. The responsecurve reflects the distributions of individual threshold photoperiods in three differentranges corresponding to the minimum number of dar...
متن کامل//steroid Hormones and Regulation of Ovarian Function
A family of C29 4,4-dimethylsterol intermediates in the cholesterol biosynthetic pathway from lanosterol has been found to induce oocytes to resume meiosis.[248] One of these sterols, 4,4-dimethyl-5α-cholest-8,14,24-triene-3β-ol, was extracted from human follicular fluid and named follicular fluid meiosis–activating substance (FF-MAS). A related compound, 4,4-dimethyl-5α-cholest-8,24-diene-3β-o...
متن کاملStress hormones: their interaction and regulation.
Stress stimulates several adaptive hormonal responses. Prominent among these responses are the secretion of catecholamines from the adrenal medulla, corticosteroids from the adrenal cortex, and adrenocorticotropin from the anterior pituitary. A number of complex interactions are involved in the regulation of these hormones. Glucocorticoids regulate catecholamine biosynthesis in the adrenal medu...
