In this study, AR42J pancreatic acinar cells were used to investigate if glucagon-like peptide-1 (GLP-1) or glucagon might influence amylase release and acinar cell function. We first confirmed the presence of GLP-1 receptors on AR42J cells by revers

Glucagon-like peptide-1 (GLP-1) enhances insulin biosynthesis and secretion as well as transcription of the insulin, GLUT2 and glucokinase genes. The latter are also regulated by the PDX-1 homeoprotein. We investigated the possibility that GLP-1 may

Glucagon-stimulated adenylyl cyclase activity has been shown to change in liver membranes manipulated to alter either their fatty acid composition or fluidity. We examined whether membrane alterations induced by dietary manipulation affected receptor
Exendin-4 (EX-4), a long acting agonist of GLP-1, induces an endocrine phenotype in Capan-1 cells. Under culture conditions which include serum, approximately 10% of the cells contain insulin and glucagon. When exposed to EX-4 (0.1 nM, up to 5 days),

In this article, we show that glucagon-like peptide 1 (GLP-1) can induce AR42J cells to differentiate into insulin, pancreatic polypeptide, and glucagon-positive cells. In their natural state, these cells, which are derived from a chemically induced

Stimulation of adenylate cyclase by high concentrations of Mg 2+ has been attributed to either occupation of a divalent cation site on the enzyme or Mg 2+ binding of inhibitory species of uncomplexed ATP. However, the stimulation of adenylate cyclase

The effects of inorganic salts on adenylate cyclase activities were studied in rat liver homogenates, particulates, and purified membranes. Na+ salts of N-3, NO-2, S2O32-, SO42-, and non-F- halides stimulated homogenates by a maximum of 2---5-fold; h

Adenylyl cyclase of rat liver and fat cells is activated by chloride, bromide, and iodide in addition to fluoride, previously believed to be uniquely effective among the halide anions. Liver homogenates are activated approximately 6 fold by fluoride

GDP regulation of basal and receptor-mediated catecholamine-sensitive human fat cell adenylate cyclase was studied using purified plasma membrane preparations and assay conditions selected to minimize conversion of GDP to GTP. Under ordinary assay co

The adenylate cyclase of an adrenocortical carcinoma of the rat is activated not only by ACTH but also by beta-adrenergic agonists, which bind to ectopic beta-adrenergic receptors not present in normal rat adrenal cortex. Previous reports examining p
