Intrinsic properties and regulation of Pannexin 1 channel [PDF]

open access: yesChannels, 2014
Pannexin 1 (Panx1) channels are generally represented as non-selective, large-pore channels that release ATP. Emerging roles have been described for Panx1 in mediating purinergic signaling in the normal nervous, cardiovascular, and immune systems, where they may be activated by mechanical stress, ionotropic and metabotropic receptor signaling, and via ...

Distinct Molecular Mechanisms Underlying Potassium Efflux for NLRP3 Inflammasome Activation

open access: yesFrontiers in Immunology, 2020
The NLRP3 inflammasome is a core component of innate immunity, and dysregulation of NLRP3 inflammasome involves developing autoimmune, metabolic, and neurodegenerative diseases.

Small Cell Lung Cancer Establishes a Metabolic Autocrine Mechanism Through Active Extracellular ATP Transport

open access: yesCancer Science, EarlyView.
Small cell lung cancer (SCLC) actively exports ATP through PANX1 channels, triggering P2RX7‐mediated autocrine signaling and promoting tumor proliferation. Inhibition of PANX1 or P2RX7 disrupts this loop and suppresses tumor growth. ABSTRACT Small cell lung cancer (SCLC) is an aggressive malignancy with a 5‐year survival rate of less than 7%.

Regulation of pannexin channels by post‐translational modifications

open access: yesFEBS Letters, 2014
The large‐pore channels formed by the pannexin family of proteins have been implicated in many physiological and pathophysiological functions, mainly through their ATP release function. However, a tight regulation of channel opening is necessary to modulate their function in vivo.

A review of the current state of pannexin channels as they relate to the blood vessel wall

open access: yesJournal of Medical Sciences, 2017
Pannexin proteins comprise a family of channels whose sole function, to date, is the release of nucleotides (e.g., adenosine 5'-triphosphate [ATP] and uridine 5′-triphosphate [UTP]).

Cryo-EM structures of an LRRC8 chimera with native functional properties reveal heptameric assembly

open access: yeseLife, 2023
Volume-regulated anion channels (VRACs) mediate volume regulatory Cl- and organic solute efflux from vertebrate cells. VRACs are heteromeric assemblies of LRRC8A-E proteins with unknown stoichiometries.

Mechanical motion promotes expression of Prg4 in articular cartilage via multiple CREB-dependent, fluid flow shear stress-induced signaling pathways [PDF]

open access: yes, 2013
Lubricin is a secreted proteoglycan encoded by the Prg4 locus that is abundantly expressed by superficial zone articular chondrocytes and has been noted to both be sensitive to mechanical loading and protect against the development of osteoarthritis.

Cells and ionic conductances contributing to spontaneous activity in bladder and urethral smooth muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cells and conductances contributing to spontaneous activity in the lower urinary tract. Bladder and urethra exhibit spontaneous contractions at both cellular and tissue levels. Both detrusor and urethral smooth muscle cells display activity that is regular and rhythmic.

Endothelial pannexin 1–TRPV4 channel signaling lowers pulmonary arterial pressure in mice

open access: yeseLife, 2021
Pannexin 1 (Panx1), an ATP-efflux pathway, has been linked with inflammation in pulmonary capillaries. However, the physiological roles of endothelial Panx1 in the pulmonary vasculature are unknown.

6‐Methylsulfinylhexyl isothiocyanate activates carbonic anhydrase‐dependent HCO3−/H+/Na+/Ca2+ transport via SLC4As–NHE–NCX–PMCA axis in odontoblasts

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend 6‐Methylsulfinylhexyl isothiocyanate (6‐MSITC, hexaraphane), a wasabi sulfinyl compound, activates intracellular carbonic anhydrase (CA)‐mediated sequential HCO3−, Na+, H+ and Ca2+ transport through an activation axis involving HCO3−‐transporting solute carrier family 4 (SLC4As), the Na+–H+ exchanger (NHE), the Na+–Ca2+ exchanger
