KCNJ8-S422L as pathogenic for J-wave syndromes failed to appropriately account for European population structure and the variant is likely benign, or (b) Ashkenazi Jews may be at significantly increased risk of J-wave syndromes
We identified a de novo missense mutation encoding Kir6.1[p.Cys176Ser] in the patient. Kir6.1[p.Cys176Ser] channels exhibited markedly higher activity than wild-type channels, as a result of reduced ATP sensitivity.
Data indicate that pharmacological KvLQT1 (zeige KCNQ1 Antikörper) and KATP (Kir6.1) inhibition or silencing with siRNAs down-regulated alpha-ENaC (zeige SCNN1A Antikörper) expression.
The KCNJ8-S422L variant was shown to be associated with both increased susceptibility to atrial fibrillation and early repolarization.
results suggest that acting on the 3'-UTR (zeige UTS2R Antikörper) of Kir6.1 and the coding region of SUR2B (zeige ABCC9 Antikörper), methylglyoxal causes instability of Kir6.1 and SUR2B (zeige ABCC9 Antikörper) mRNAs, disruption of vascular K(ATP) channels, and impairment of arterial function
Data suggest that Kir6.1 and M3 muscarinic receptor (zeige CHRM3 Antikörper) colocalize to detrusor caveolae; studies include tissue from both male and female subjects.
The researchers report evidence that the KCNJ8 gene increases susceptiblity to the brugada syndrome and early repolarization syndrome.
The mutations localized to Kir6.1's C-terminus, involved conserved residues and the pinacidil-activated K(ATP) current was decreased 45% to 68% for Kir6.1-E332del and 40% to 57% for V346I between -20 mV and 40 mV.
Down-regulation of Kir6.1 and Kir6.2 (zeige KCNJ11 Antikörper) expression in myometrium may contribute to the enhanced uterine contractility associated with the onset of labour.
Interaction with caveolin-1 causes a shift the channel's sensitivity to its physiological regulator magnesium ADP (MgADP).
Together, these results implicate the incorporation of native Kir6.1 subunits into pancreatic KATP channels and a contributory role for these subunits in the control of insulin (zeige INS Antikörper) secretion.
data support the existence of an endothelial KATP channel that contains Kir6.1, is involved in vascular reactivity in the coronary circulation, and has a protective role in ischemia reperfusion.
both Kir6.1(V65M) and Kir6.2 (zeige KCNJ11 Antikörper)(V64M) mutations essentially abolish high-affinity sensitivity to the KATP blocker glibenclamide in both intact cells and excised patches. This raises the possibility that, at least for some CS mutations, sulfonylurea therapy may not prove to be successful and highlights the need for detailed pharmacogenomic analyses of CS mutations.
Similar to previous results in Kir6.1(-/-) myocytes, Kir6.1 gain of function myocytes demonstrate resistance (less volume derangement) to stress of cardioplegia.
K(ATP) channel gain-of-function leads to increased myocardial L-type Ca(2 (zeige CA2 Antikörper)+) current and contractility in Cantu (zeige ABCC9 Antikörper) syndrome.
Kcnj8 mutation is responsible of heart conduction abnormalities in Cantu (zeige ABCC9 Antikörper) syndrome.
our study demonstrated that exercise training up-regulated Kir6.1, improved tissue oxygenation recovery, and protected the heart against I/R injury
Results suggest that the vascular KATP channel Kcnj8 is organ protective in diabetic conditions.
The absence of Kir6.1 does not affect the contractile properties of myocytes during stress, suggesting the absence of Kir6.1 improves myocyte tolerance to stress via an unknown mechanism.
Sulfhydration of SUR2B (zeige ABCC9 Antikörper) subunit modifies tyrosine nitration of Kir6.1 subunit within the KATP channel complex.
Results describe a new function of the Kir6.1-SUR2A (zeige ABCC9 Antikörper) complex, namely the regulation of paracellular permeability through tight junctions.
The predominant K(ATP) channel expressed in pig urethral smooth muscle possesses a unique, heteromeric pore structure with a pore-forming subunit composition of (Kir6.1)(3)-(Kir6.2 (zeige KCNJ11 Antikörper)).
Kir6.1/SUR2B is the major functional K(ATP) channel complex in the pig MMA and MCA, and mRNA expression studies suggest that the human MMA shares this K(ATP) channel subunit profile
Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. The encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. Defects in this gene may be a cause of J-wave syndromes and sudden infant death syndrome (SIDS).
