[HTML][HTML] Pannexin 1 facilitates arterial relaxation via an endothelium-derived hyperpolarization mechanism

D Gaynullina, VI Shestopalov, Y Panchin, OS Tarasova - FEBS letters, 2015 - Elsevier
Abstract Pannexin 1 (Panx1) is involved in endothelium-dependent vasodilation in large
arteries, but the exact mechanistic role remains poorly understood. We hypothesized that …

Pannexin 1 in the regulation of vascular tone

M Billaud, JK Sandilos, BE Isakson - Trends in cardiovascular medicine, 2012 - Elsevier
Pannexins are a recently discovered protein family with the isoform Panx1 ubiquitously
expressed and therefore extensively studied. Panx1 proteins form membrane channels …

[HTML][HTML] Endothelial function is impaired in conduit arteries of pannexin1 knockout mice

D Gaynullina, OS Tarasova, OO Kiryukhina… - Biology direct, 2014 - Springer
Pannexin1 is ubiquitously expressed in vertebrate tissues, but the role it plays in vascular
tone regulation remains unclear. We found that Pannexin1 expression level is much higher …

Novel pannexin‐1‐coupled signaling cascade involved in the control of endothelial cell function and NO‐dependent relaxation

MA Lillo, PS Gaete, M Puebla… - Oxidative Medicine …, 2021 - Wiley Online Library
Deletion of pannexin‐1 (Panx‐1) leads not only to a reduction in endothelium‐derived
hyperpolarization but also to an increase in NO‐mediated vasodilation. Therefore, we …

Pannexin1 regulates α1-adrenergic receptor–mediated vasoconstriction
