Pituitary adenylate cyclase-activating polypeptide (PACAP) stimulates adenylate cyclase and promotes proliferation of mouse primordial germ cells.
During migration and for about 2 days after their arrival in the gonadal ridges, primordial germ cells (the embryonic precursors of gametes of the adult animal) proliferate actively. Certain growth factors, such as stem cell factor and leukemia inhibitory factor, seem to be essential for survival, proliferation and possibly differentiation of mouse primordial germ cell in vivo and/or in vitro. ...
متن کاملE VALUATION OF ADENYLATE CYCLASE ACTIVITY IN MITRAL VALVE PROLAPSE
The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...
متن کاملadenylate cyclase activity
Adipocyte membranes from control rats exhibited a functional Gi (inhibitory guanine-nucleotide-binding protein) activity which could be assessed either by the inhibitory action of low concentrations of guanosine 5-[/Jy-imido]triphosphate (p[NH]ppG) upon forskolin-stimulated adenylate cyclase activity or by the inhibitory action of high concentrations of GTP upon isoprenaline-stimulated adenylat...
متن کاملForskolin-activated Adenylate Cyclase
Forskolin activated adenylate cyclase of purified rat adipocyte membranes in the absence of exogenous guanine nucleotides. Guanyl-5”yl imidodiphosphate (Gpp(NH)p) inhibited the forskolin-activated cyclase immediately upon addition of the nucleotide at concentrations too low to activate adenylate cyclase (lo-’ to M). Inhibition seen with a very high concentration of Gpp(NH)p M) lasted for 3-4 m...
متن کاملAdenylate Cyclase Responsiveness to Hormones
AVP (1 ,tM) stimulated adenylate cyclase activity in the terminal nephron segments only, i.e., the late portion of the distal convoluted tubule, the cortical and medullary portions ofthe collecting tubule (activity ratios 81, 51, and 97, respectively). As measured in one experiment, nearly one-halfmaximal responses were obtained with 0.1 IU/ml PTH or 0.3 ng/ml SCT in thick ascending limbs and w...
