In order to assess the adrenergic contribution to hypoglycemic glucose counterregulation in type I diabetes mellitus and to determine whether the adrenergic contribution is mediated through beta 1- or beta 2-adrenergic receptors, hypoglycemia was induced by an i.v. insulin infusion (30 mU/m2 x min) for 60 min in 11 insulin-dependent diabetic patients (IDDM), 5 with normal plasma glucagon responses and 6 with blunted responses, and also in 7 age-weight-matched nondiabetic subjects.

|
Rates of plasma glucose decrease and postnadir increase, as well as plasma concentrations of free insulin and of counterregulatory hormones, were measured when insulin was infused alone, and when insulin was infused along with propranolol (a beta 1- and beta 2-adrenergic receptor antagonist) or metoprolol (a selective beta 1-antagonist).

|
Patients with insulin-dependent diabetes mellitus (IDDM) have been found to have a heightened hyperglycemic response to epinephrine.
|
25 |
6313456
|
To determine if patients with IDDM have increased sensitivity of cellular beta 2-adrenergic receptor-effector systems, we assessed beta 2-adrenergic receptors and adenylate cyclase sensitivities to isoproterenol in partially purified mononuclear leukocyte (MNL) plasma membranes from 10 patients with IDDM (without adrenergic neuropathy) and 10 matched nondiabetic controls.
|
26 |
6313456
|
MNL beta 2-adrenergic receptor densities (Bmax = 48 +/- 8 fmol [3H] DHA/mg protein in IDDM, 44 +/- 3 fmol [3H] DHA/mg protein in controls) and binding affinities (apparent KD = 0.3 +/- 0.07 nM in IDDM, 0.3 +/- 0.04 nM in controls) did not differ.
|
27 |
6313456
|
Further, MNL adenylate cyclase activities were not significantly different either at baseline (325 +/- 86 pmol/mg protein/15 min in IDDM, 275 +/- 49 pmol/mg protein/15 min in controls) or in response to isoproterenol (842 +/- 229 pmol/mg protein/15 min in IDDM, 608 +/- 86 pmol/mg protein/15 min in controls).
|
28 |
6313456
|
Thus, the data do not support the presence of a generalized alteration of beta-adrenergic receptors or adenylate cyclase sensitivity in IDDM.
|
29 |
6313456
|
To the extent that MNL beta 2-adrenergic receptors and adenylate cyclase activities reflect those of extravascular catecholamine target cells, these findings suggest that the heightened hyperglycemic response to epinephrine exhibited by patients with IDDM is not due to increased sensitivity of cellular beta 2-adrenergic receptor-effector systems and is best attributed to the altered hormonal milieu of the insulin-deficient state.

Internalization of the gastrin-releasing peptide receptor is mediated by both phospholipase C-dependent and -independent processes.
|
54 |
7935330
|
Results with receptors linked to adenylate cyclase, such as the beta 2-adrenergic receptor, or receptors linked to phospholipase C (PLC) have provided conflicting results regarding the role of second messenger-dependent (i.e., protein kinase A or C) and -independent (i.e., beta-adrenergic receptor kinase) kinases in mediating this process.
|
55 |
7935330
|
Recent results for truncated and mutated gastrin-releasing peptide (GRP) receptors (GRP-R), as well as muscarinic cholinergic receptors, suggest that activation of protein kinase C may be needed for full receptor internalization.
|
56 |
7935330
|
We selectively mutated each of these residues in the GRP-R to determine their importance for activation of PLC.
|
57 |
7935330
|
Both R139G (Kd = 12.0 +/- 1.6 nM) and A263E (Kd = 12.2 +/- 1.7 nM) had a lower affinity for bombesin than did wild-type GRP-R (Kd = 1.4 +/- 0.4 nM); however, characteristic stoichiometries for the binding of agonists to this receptor were maintained equally in all three cell lines (bombesin > GRP >> neuromedin B).
|
58 |
7935330
|
The wild-type GRP-R exposed to bombesin increased [3H]inositol phosphates (a measure of PLC activation) approximately 4-fold, with an EC50 of 5.1 +/- 2.2 nM.
|
59 |
7935330
|
In contrast, [3H]inositol phosphates were not significantly increased in cells expressing R139G or A263E receptors, demonstrating that Arg139 and Ala263 are required for GRP-R activation of PLC.

Loss of adrenergic hypoglycaemic symptoms is the most distinctive feature in insulin-dependent diabetes mellitus (IDDM) patients with hypoglycaemia unawareness.
|
62 |
8577639
|
This study was carried out to investigate whether the reduced adrenergic sensitivity in IDDM patients with hypoglycaemia unawareness (IDDM-unaware) also could be demonstrated as reduced increase in cAMP production in mononuclear leucocytes induced by isoprenaline stimulation, or reduced inhibition by ICI-118551 (a selective beta 2-adrenergic receptor blocker) of isoprenaline induced cAMP production.

The counterregulatory actions of insulin on catecholamine action are well known and include phosphorylation of the beta(2)-adrenergic receptor on Tyr(350), Tyr(354), and Tyr(364) in the C-terminal cytoplasmic domain, as well as enhanced sequestration of the beta(2)-adrenergic receptor.

10999801
|
This study examined whether the simultaneous presence of the previously identified Trp/Arg64 polymorphism of the beta3-adrenergic receptor (BAR) gene and the -3826 A-->G nucleotide variant of the uncoupling protein-1 (UCP1) gene are associated with obesity, insulin resistance, or alterations in size at birth in a Danish study population comprising 379 unrelated young Caucasian subjects.
|
110 |
10999801
|
The subjects were divided into 4 groups according to their BAR and UCP1 genotype: wild-type carriers (n = 184), only Trp/Arg64 carriers (n = 29), only A-->G UCP1 carriers (n = 146), and carriers of both genetic variants (n = 20).
|
111 |
10999801

c-Src tyrosine kinase binds the beta 2-adrenergic receptor via phospho-Tyr-350, phosphorylates G-protein-linked receptor kinase 2, and mediates agonist-induced receptor desensitization.
|
121 |

We constructed a chimeric receptor with the ligand-binding and transmembrane segments from the beta2-adrenergic receptor (beta2AR) and the cytoplasmic domains from rat Frizzled-1 (Rfz1).
|
125 |

|
Stimulation of mouse F9 clones expressing the chimera (beta2AR-Rfz1) with the beta-adrenergic agonist isoproterenol stimulated stabilization of beta-catenin, activation of a beta-catenin-sensitive promoter, and formation of primitive endoderm.
|
126 |

|
Thus, G proteins are elements of Wnt/Frizzled-1 signaling to the beta-catenin-lymphoid-enhancer factor (LEF)-T cell factor (Tcf) pathway.

Increments in insulin sensitivity during intensive treatment are closely correlated with decrements in glucocorticoid receptor mRNA in skeletal muscle from patients with Type II diabetes.
|
128 |
11672459
|
To test the hypothesis that changes in the expression of the glucocorticoid receptor (GCR) and the beta(2)-adrenoceptor (beta(2)-AR) contribute significantly to the abnormal glucose metabolism in skeletal muscle from patients with Type II diabetes, we have examined (1) the levels of total GCR (alpha+beta isoforms), the alpha/alpha 2 isoform of GCR and beta(2)-AR mRNAs in skeletal muscle from insulin-resistant patients with Type II diabetes (n=10) and healthy controls (n=15), and (2) the effects of 8 weeks of intensive treatment on the whole-body glucose disposal rate and on total GCR, alpha/alpha 2 GCR and beta(2)-AR mRNA levels in diabetic patients.
|
129 |
11672459
|
Total GCR (P=0.005), alpha/alpha 2 GCR (P=0.005) and beta(2)-AR (P=0.03) mRNA levels all decreased significantly after intensive insulin treatment.
|
130 |
11672459
|
In conclusion, the abnormal regulation of GCR mRNA is likely to play a significant role in the insulin resistance observed in obese patients with Type II diabetes.

12012019
|
Using a chimeric receptor composed of the exofacial and the transmembrane, ligand-binding domain of the beta(2)-adrenergic receptor (beta2AR) fused with the corresponding cytoplasmic domains of the rat Frizzled-1 receptor (Rfz1), we created a unique chimera between distant members of the superfamily of G protein-coupled receptors.

|
201 |
14693408
|
The Gly/Gly group had significantly higher levels of fasting insulin (38.2+/-4.7 pmol/l versus 23.6+/-3.5 pmol/l) and homeostasis model assessment of insulin resistance (HOMA-R) (1.90+/-0.19 versus 1.32+/-0.24), compared with the Arg/Arg group, but there were no significant differences in acute insulin response to glucose (AIRg) bolus, insulin sensitivity (Si), or glucose effectiveness (Sg) among the three genotypes.

The beta(2)-adrenergic receptor (B2AR) is expressed in pancreatic beta-cells and modulates insulin secretion.
|
224 |
14693408
|
The purpose of the present study was to evaluate the influence of the Arg16Gly variant allele of B2AR on insulin secretion in patients with type 2 diabetes.
|
225 |
14693408
|
The Gly/Gly group had significantly higher levels of fasting insulin (38.2+/-4.7 pmol/l versus 23.6+/-3.5 pmol/l) and homeostasis model assessment of insulin resistance (HOMA-R) (1.90+/-0.19 versus 1.32+/-0.24), compared with the Arg/Arg group, but there were no significant differences in acute insulin response to glucose (AIRg) bolus, insulin sensitivity (Si), or glucose effectiveness (Sg) among the three genotypes.
|
226 |
14693408
|
Several reports have speculated that the Gly16 allele of B2AR exhibits agonist-promoted downregulation, but our findings, elevated fasting insulin concentrations, and previous clinical studies of blood pressure and lypolysis are controversial.
|
227 |
14693408
|
The direct mechanism by which the Gly16 allele of B2AR may influence insulin secretion of pancreatic beta-cells is unknown.
|
228 |
14693408
|
Further studies of the expression of the allelic receptor in islet cells may help to resolve the role of B2AR in insulin secretion.

C3 exotoxin, expression of dominant negative RhoA, and inhibition of c-Jun N-terminal kinase blocked the ability of lysophosphatidic acid to sequester the beta(2)-adrenergic receptor, whereas expression of constitutively active Galpha(13), p115RhoGEF, or RhoA mimicked lysophosphatidic acid (LPA) action, stimulating the internalization of the Galpha(s)-coupled beta(2)-adrenergic receptor.

|
This study revealed a novel cross-talk exerted from the LPA/Galpha(13)/p115RhoGEF/RhoA pathway to the beta(2)-adrenergic receptor/Galpha(s)/adenylyl cyclase pathway, attenuating the ability of beta-adrenergic agonists to act following stimulation of cells by LPA as may occur during beta-adrenergic therapy of an inflammatory response.

We genotyped 11 single nucleotide polymorphisms for 10 obesity candidate genes including adrenergic beta-2-receptor surface, adrenergic beta-3-receptor surface, angiotensinogen, fat mass and obesity associated gene, guanine nucleotide binding protein beta polypeptide 3 (GNB3), interleukin 6 receptor, proprotein convertase subtilisin/kexin type 1 (PCSK1), uncoupling protein 1, uncoupling protein 2, and uncoupling protein 3.
|
245 |
19594364
|
Single-locus analyses showed significant main effects of the GNB3 and PCSK1 genes on the risk of T2D among the nonobese group (p = 0.002 and 0.047, respectively).
|
246 |
19594364
|
Further, interactions involving GNB3 and PCSK1 were suggested among the nonobese population using the generalized multifactor dimensionality reduction method (p = 0.001).
|
247 |
19594364
|
In addition, interactions among angiotensinogen, fat mass and obesity associated gene, GNB3, and uncoupling protein 3 genes were found in a significant four-locus generalized multifactor dimensionality reduction model among the obese population (p = 0.001).

Cell-to-cell interaction through binding of intercellular adhesion molecule-1 (ICAM-1) and CD40 on monocytes to their ligands on T-cells plays crucial roles in cytokine production.
|
250 |
19857486
|
In a previous study, we found that glyceraldehyde-derived AGE (AGE-2) and glycolaldehyde-derived AGE (AGE-3) at 100 microg/ml induced the expressions of ICAM-1 and CD40 on monocytes and the production of interferon (IFN)-gamma and tumor necrosis factor (TNF)-alpha in human peripheral blood mononuclear cells. beta(2)-adrenoceptor stimulation has been demonstrated to modulate the production of inflammatory mediators.

Additionally, they are ligands for a G-protein-coupled BA receptor (TGR5/Gpbar-1) and activate nuclear receptors such as farnesoid X receptor (FXR; NR1H4).
|
252 |
20460915
|
BA-activated FXR and signal transduction pathways are also involved in the regulation of hepatic gluconeogenesis, glycogen synthesis and insulin sensitivity.
|
253 |
20460915
|
Via TGR5, BA are able to stimulate glucagon-like peptide-1 secretion in the small intestine and energy expenditure in brown adipose tissue and skeletal muscle.
|
254 |

|
As such, FXR and/or TGR5 ligands have shown promising results in animal models of NAFLD and clinical pilot studies.

Here, we identify the lipid binding BAR (Bin/amphiphysin/Rvs) domain protein PICK1 (protein interacting with C kinase 1) as a key component early in the biogenesis of secretory vesicles in GH-producing cells.
|
288 |
23630454
|
PICK1 localized in cells to immature secretory vesicles, and the PICK1 BAR domain was shown by live imaging to associate with vesicles budding from the TGN and to possess membrane-sculpting properties in vitro.
|
289 |
23630454
|
In mouse pituitary, PICK1 co-localized with the BAR domain protein ICA69, and PICK1 deficiency abolished ICA69 protein expression.

|
In the Drosophila brain, PICK1 and ICA69 co-immunoprecipitated and showed mutually dependent expression.
|
