Rapid desensitization of neonatal rat liver beta-adrenergic receptors. A role for beta-adrenergic receptor kinase. [PDF]

open access: bronzeJournal of Clinical Investigation, 1994
Exposure of beta-adrenergic receptors (BAR) to agonists often leads to a rapid loss of receptor responsiveness. The proposed mechanisms of such rapid receptor desensitization include receptor phosphorylation by either cAMP-dependent protein kinase or the specific beta-adrenergic receptor kinase (BARK), leading to functional uncoupling from adenylyl ...

β-Adrenergic Receptor Kinase (GRK2) Colocalizes with β-Adrenergic Receptors during Agonist-induced Receptor Internalization [PDF]

open access: yesJournal of Biological Chemistry, 1997
Rapid regulation of G protein-coupled receptors appears to involve agonist-promoted receptor phosphorylation by G protein-coupled receptor kinases (GRKs). This is followed by binding of uncoupling proteins termed arrestins and transient receptor internalization. In this report we show that the beta-adrenergic receptor kinase (betaARK-1 or GRK2) follows

Rapid agonist‐induced beta‐adrenergic receptor kinase translocation in C6 glioma cells [PDF]

open access: bronzeFEBS Letters, 1992
Exposure of C6 glioma cells to 1 μM isoproterenol leads to fast desensitization of the β‐adrenergic receptor/adenylyl cyclase system and transient receptor sequestration. It also triggers a very rapid and transient translocation to the plasma membrane or β‐adrenergic receptor kinase (βARK), a specific cytoplasmic kinase that phosphorylates only the ...

Inhibition of beta-adrenergic receptor kinase prevents rapid homologous desensitization of beta 2-adrenergic receptors. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1989
Homologous (agonist-specific) desensitization of beta-adrenergic receptors (beta ARs) is accompanied by and appears to require phosphorylation of the receptors. We have recently described a novel protein kinase, beta AR kinase, which phosphorylates beta ARs in vitro in an agonist-dependent manner.

G-Protein Inwardly Rectifying Potassium Channel 1 (GIRK1) Knockdown Decreases Beta-Adrenergic, MAP Kinase and Akt Signaling in the MDA-MB-453 Breast Cancer Cell Line

open access: yesBreast Cancer: Basic and Clinical Research, 2008
Previous data from our laboratory have indicated that there is a functional link between the beta-adrenergic receptor signaling pathway and the G-protein inwardly rectifying potassium channel (GIRK1) in breast cancer cell lines and that these pathways ...

Paroxetine Attenuates Cardiac Hypertrophy Via Blocking GRK2 and ADRB1 Interaction in Hypertension

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background ADRB1 (adrenergic receptor beta 1) responds to neuroendocrine stimulations, which have great implications in hypertension. GRK2 (G protein‐coupled receptor kinase 2) is an essential regulator for many G protein‐coupled receptors and subsequent

Mechanism of β-Adrenergic Receptor Desensitization in Cardiac Hypertrophy Is Increased β-Adrenergic Receptor Kinase [PDF]

open access: yesJournal of Biological Chemistry, 1997
Pressure overload cardiac hypertrophy in the mouse was achieved following 7 days of transverse aortic constriction. This was associated with marked beta-adrenergic receptor (beta-AR) desensitization in vivo, as determined by a blunted inotropic response to dobutamine. Extracts from hypertrophied hearts had approximately 3-fold increase in cytosolic and

Activation of the Thiazide-Sensitive Sodium-Chloride Cotransporter by Beta3-Adrenoreceptor in the Distal Convoluted Tubule

open access: yesFrontiers in Physiology, 2021
We previously showed that the beta-3 adrenergic receptor (BAR3) is expressed in most segments of the nephron where its agonism promotes a potent antidiuretic effect.

Altered expression of beta-adrenergic receptor kinase and beta 1-adrenergic receptors in the failing human heart. [PDF]

open access: yesCirculation, 1993
BACKGROUND In chronic heart failure, the positive inotropic effects of beta-adrenergic receptor agonists are greatly reduced, in part as a result of two alterations of the cardiac beta-adrenergic receptors: loss of their function (receptor uncoupling) and reduction of their number (downregulation).

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...
