Wine polyphenol resveratrol inhibits contractions of isolated rat uterus by activation of smooth muscle inwardly rectifying potassium channels [PDF]

open access: yesVeterinarski Glasnik, 2016
Resveratrol is a phytoalexin produced in a number of plant species including grapes. The benefit of resveratrol to health is widely reported. Resveratrol has been found to promote relaxation of non-pregnant and pregnant uterus, but its mechanism

The Relevance of GIRK Channels in Heart Function

open access: yesMembranes, 2022
Among the large number of potassium-channel families implicated in the control of neuronal excitability, G-protein-gated inwardly rectifying potassium channels (GIRK/Kir3) have been found to be a main factor in heart control. These channels are activated

Computational Insights Into Voltage Dependence of Polyamine Block in a Strong Inwardly Rectifying K+ Channel

open access: yesFrontiers in Pharmacology, 2020
Inwardly rectifying potassium (KIR) channels play important roles in controlling cellular excitability and K+ ion homeostasis. Under physiological conditions, KIR channels allow large K+ influx at potentials negative to the equilibrium potential of K ...

Ras-association domain of sorting Nexin 27 is critical for regulating expression of GIRK potassium channels. [PDF]

open access: yesPLoS ONE, 2013
G protein-gated inwardly rectifying potassium (GIRK) channels play an important role in regulating neuronal excitability. Sorting nexin 27b (SNX27b), which reduces surface expression of GIRK channels through a PDZ domain interaction, contains a putative ...

Perisynaptic astrocytes as a potential target for novel antidepressant drugs

open access: yesJournal of Pharmacological Sciences, 2021
Emerging evidence suggests that dysfunctions in glutamatergic signaling are associated with the pathophysiology of depression. Several molecules that act on glutamate binding sites, so-called glutamatergic modulators, are rapid-acting antidepressants ...

Pharmacological Characterization of 5-HT1A Autoreceptor-Coupled GIRK Channels in Rat Dorsal Raphe 5-HT Neurons.

open access: yesPLoS ONE, 2015
G protein-activated inwardly rectifying potassium (GIRK) channels in 5-HT neurons are assumed to be principal effectors of 5-hydroxytryptamine 1A (5-HT1A) autoreceptors, but their pharmacology, subunit composition and the role in regulation of 5-HT ...
