Effect of polybrominated biphenyls on adenylate cyclase activity in rat lung alveoli.
The in vitro effect of polybrominated biphenyls (FireMaster BP-6) on adenylate cyclase [ATP pyrophosphate lyase (cyclizing), EC 4.6.1.1] activity in plasma membranes of rat lung alveoli was determined. Two fractions of plasma membranes, PM-I (approximate d = 1.13 g/cm3) and PM-II (approximate d = 1.16 g/cm3) were isolated under hypotonic homogenization and fractionation conditions (1mM NaHCO3, ...
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 کاملEffect of thuringiensin on adenylate cyclase in rat cerebral cortex.
The purpose of this work is to evaluate the effect of thuringiensin on the adenylate cyclase activity in rat cerebral cortex. The cyclic adenosine 3'5'-monophosphate (cAMP) levels were shown to be dose-dependently elevated 17-450% or 54-377% by thuringiensin at concentrations of 10 microM-100 mM or 0.5-4 mM, due to the activation of basal adenylate cyclase activity of rat cerebral cortical memb...

متن کاملAdenylate cyclase activity during exocrine pancreatic proliferation in the rat.
Adenylate cyclase activity in pancreatic acinar cell membranes was determined in rats that had undergone a treatment with pentagastrin (250 micrograms/kg, intraperitoneal three times daily) for 1 week or that had undergone small bowel resection (90%) and were sacrified at 2 weeks, 1 month and 6 months after intervention. Both treatments are potent stimulators of pancreatic acinar cell prolifera...
