The subcellular localization of the heterotrimeric G-proteins in hepatocytes in situ was compared to that in hepatocytes in primary culture. The ability of various ligands to activate adenylyl cyclase (AC) in membrane preparations was also investigat

Stromal vascular cells from epididymal fat pads of lean and obese mice were cultured in a medium (alpha-MEM) containing fetal bovine serum (FBS) and cell replication followed for 11 days. In both types of cells, confluence occurred at 4-5 days, after

Lipolysis and adenylyl cyclase (AC) activation in response to beta-adrenergic agents are abnormally low in white epididymal adipose tissue (WAT) of the ob/ob mouse. The abundance of G-proteins (Gs alpha and Gi alpha) linked to AC is also abnormally l

The HGFu and Ob17 cell lines, derived from adipose tissue of lean (+/?) and ob/ob mice, respectively, express several G-protein peptides. Investigation of the expression and subcellular localization of the Giα3 subunit showed that this peptide is as

G-protein levels were assessed in liver and brain membranes of lean and obese mice. ADP-ribosylation and immunodetection studies revealed a decrease in the abundance of Gs and Gi alpha-subunits in the liver membranes of obese mice compared with lean

The abundance of the alpha and beta subunits of the GTP-binding proteins (G-proteins) that transduce hormonal messages to adenylate cyclase was assessed in adipocyte membranes from lean (+/+) and obese (ob/ob) mice, using ADP-ribosylation with bacter

The present study was undertaken to determine whether factors that affect K+ permeability produce differences in insulin secretion in the islets of obese versus lean mice. At basal glucose (3 mM), the obese islets secreted more insulin for a given in

The subcellular localization of G5 alpha, Gi alpha 1&2, Gi alpha 3, and G beta was studied in primary-cultured undifferentiated and differentiated, lipid replete, adipose cells. The results show a distinct distribution for each of these G-proteins an

The metabolic response of adipose tissue to stimuli leading to lipid mobilization is important in determining the direction of metabolism and the degree to which adipose tissue can store lipids and release fatty acids in times of need. The lipolytic

Glucose-induced insuline release, glucose-induced rises in intracellular free Ca 2+ concentration ([Ca 2+ ] i ), and voltage-dependent Ca 2+ channel activity were assessed in monolayer cultures of β-vells 3–5 day-old rats. The glucose-stimulated i
