Identification of a novel class of mammalian phosphoinositol-specific phospholipase C enzymes. [PDF]

, 2010
Phosphoinositol (PhoIns)-specific phospholipase C enzymes (PLCs) are central to the inositol lipid signaling pathways and contribute to intracellular Ca2+ release and protein kinase C activation. Five distinct classes of PhoIns-specific PLCs are known to

Presynaptic enhancement of excitatory synaptic transmission by beta-adrenergic receptor activation [PDF]

, 1994
1. Previous studies have shown that beta-adrenergic receptor activation has many effects on neuronal function in hippocampal area CA1. However, all of the physiological effects of beta-adrenergic receptor activation in this region reported to date have ...

Overexpression of a Neuronal Type Adenylyl Cyclase (Type 8) in Sinoatrial Node Markedly Impacts Heart Rate and Rhythm

Frontiers in Neuroscience, 2019
Heart rate (HR) and HR variability (HRV), predictors of over-all organism health, are widely believed to be driven by autonomic input to the sinoatrial node (SAN), with sympathetic input increasing HR and reducing HRV. However, variability in spontaneous

Activation by G protein beta gamma subunits of beta-adrenergic and muscarinic receptor kinase.

Journal of Biological Chemistry, 1993
We have shown previously that GTP-binding regulatory protein (G protein) beta gamma subunits stimulate the agonist- or light-dependent phosphorylation of muscarinic acetylcholine receptors (mAChRs) and rhodopsin by a protein kinase partially purified from porcine brain (mAChR kinase) but not the phosphorylation of rhodopsin by rhodopsin kinase (Haga, K.

Aniridia‐associated keratopathy: Clinical and molecular mechanisms of disease progression and emerging therapeutic targets

Acta Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare genetic disorder primarily caused by pathogenic variants of the PAX6 gene. It leads to various panocular anomalies, including aniridia‐associated keratopathy (AAK). This review highlights recent insights into its pathogenesis, focusing on clinical staging, microstructural changes in the cornea and molecular ...

MicroRNA interactome analysis predicts post-transcriptional regulation of ADRB2 and PPP3R1 in the hypercholesterolemic myocardium

Scientific Reports, 2018
Little is known about the molecular mechanism including microRNAs (miRNA) in hypercholesterolemia-induced cardiac dysfunction. We aimed to explore novel hypercholesterolemia-induced pathway alterations in the heart by an unbiased approach based on miRNA ...

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes

British Journal of Pharmacology, EarlyView.
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

Novel approaches for drug development against chronic primary pain: A systematic review

British Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Negative antagonists promote an inactive conformation of the beta 2-adrenergic receptor. [PDF]

, 1994
The beta 2-adrenergic receptor undergoes isomerization between an inactive conformation (R) and an active conformation (R*). The formation of the active conformation of the receptor molecule can be promoted by adrenergic agonists or by mutations in the ...

Substitution of an extracellular cysteine in the beta 2-adrenergic receptor enhances agonist-promoted phosphorylation and receptor desensitization. [PDF]

, 1989
We constructed and expressed in a permanent cell line a beta 2-adrenergic receptor with a valine substitution for cysteine 184 of the second putative extracellular loop.
