Targeting cardiac beta-adrenergic signaling via GRK2 inhibition for heart failure therapy

Frontiers in Physiology, 2013
Cardiac cells, like those of the other tissues, undergo regulation through membrane-bound proteins known as G protein-coupled receptors (GPCRs). β-adrenergic receptors (βARs) are key GPCRs expressed on cardiomyocytes and their role is crucial in cardiac

α1A Adrenoreceptor blockade attenuates myocardial infarction by modulating the integrin-linked kinase/TGF-β/Smad signaling pathways

BMC Cardiovascular Disorders, 2023
Background Myocardial infarction (MI) is considered a public health problem. According to the World Health Organization, MI is a leading cause of death and comorbidities worldwide. Activation of the α1A adrenergic receptor is a contributing factor to the

The Long Noncoding RNA ΒFaar Promotes White Adipose Tissue Browning and Prevents Diet‐Induced Obesity

Advanced Science, EarlyView.
βFaar selectively targets and inhibits the GTPase activity of the RAB18 protein, thereby reducing LD volume. Conversely, βFaar promotes nuclear translocation of the transcription factor IRF4 in inguinal white adipose tissue (iWAT), facilitating the browning of white adipose tissue and attenuating body fat accumulation.

Stimulation of β-adrenergic receptors plays a protective role via increased expression of RAF-1 and PDX-1 in hyperglycemic rat pancreatic islet (RIN-m5F) cells

Archives of Medical Science, 2016
Introduction : It is a widely held view that a progressive reduction of beta-cell mass occurs in the progression of diabetes. RAF-1 kinase and pancreas duodenal homeobox 1 (PDX-1) are major factors that promote survival of cells and maintain normal ...

Higenamine Attenuates Doxorubicin-Induced Cardiac Remodeling and Myocyte Apoptosis by Suppressing AMPK Activation

Frontiers in Cell and Developmental Biology, 2022
Background: As an effective antitumor drug, doxorubicin (DOX) is primarily used to treat solid tumors and hematologic malignancies. However, increasing evidence has emerged indicating its cardiotoxicity, and few solutions have been proposed to counter ...

Beta-agonist stimulation ameliorates the phenotype of spinal and bulbar muscular atrophy mice and patient-derived myotubes [PDF]

, 2017
Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disease characterized by the loss of lower motor neurons. SBMA is caused by expansions of a polyglutamine tract in the gene coding for androgen receptor (AR).

LncRNA Foxo6os as a Novel “ Scaffold” Mediates MYBPC3 in Combating Pathological Cardiac Hypertrophy and Heart Failure

Advanced Science, EarlyView.
Schematic overview showing that forkhead box O6, opposite strand (Foxo6os) acts as a “scaffold”, directly binding myosin‐binding protein‐C (MYBPC3) and recruiting protein kinase C (PKC‐α) to mediate site‐specific phosphorylation of MYBPC3. This post‐translational modification supports cardiac contraction by regulating L‐type Ca2+ channels, especially ...
