Mind the gap: connexins and cell–cell communication in the diabetic kidney [PDF]
Connexins, assembled as a hexameric connexon, form a transmembrane hemichannel that provides a conduit for paracrine signalling of small molecules and ions to regulate the activity and function of adjacent cells.

We have recently reported an important role of Connexin 43 (Cx43) hemichannels in the pathogenesis of lethal sepsis through facilitating ATP efflux to potentiate the double-stranded RNA-activated protein kinase R (PKR)-dependent macrophage activation ...

A Cationic Block Co‐Polymer for Gene Delivery in the Posterior Segment of the Eye
ABSTRACT Diseases of the back of the eye such as neovascular age‐related macular degeneration (nAMD) are vision threatening and treatment is burdensome for patients, often requiring ocular injections every other month. Injection risks and logistics lower patient compliance; however, even patients receiving optimal treatment can deteriorate.

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%.

A rare missense mutation in GJB3 (Cx31G45E) is associated with a unique cellular phenotype resulting in necrotic cell death [PDF]
Erythrokeratodermia variabilis et progressiva (EKV-P) is caused by mutations in either the GJB3 (Cx31) or GJB4 genes (Cx30.3). We identified a rare GJB3 missense mutation, c.134G>A (p.G45E), in two unrelated patients and investigated its cellular ...

Calcium Regulation of Connexin Hemichannels
Connexin hemichannels (HCs) expressed at the plasma membrane of mammalian cells are of paramount importance for intercellular communication. In physiological conditions, HCs can form gap junction (GJ) channels, providing a direct diffusive path between neighbouring cells.

Connexin43 Hemichannel-Mediated Regulation of Connexin43
Many signaling molecules and pathways that regulate gap junctions (GJs) protein expression and function are, in fact, also controlled by GJs. We, therefore, speculated an existence of the GJ channel-mediated self-regulation of GJs. Using a cell culture model in which nonjunctional connexin43 (Cx43) hemichannels were activated by cadmium (Cd(2+)), we ...

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Pharmacological Separation of Mechanosensory Mechanisms in Rat Urinary Bladder Ex Vivo
ABSTRACT The local response of the bladder wall to stretch is believed to result from the coordinated activation of mechanosensitive ion channels located in the plasma membrane of the cells that form the wall's urothelial and detrusor smooth muscle (DSM) layers.

The Role of Connexin and Pannexin Channels in Perinatal Brain Injury and Inflammation
Perinatal brain injury remains a major cause of death and life-long disability. Perinatal brain injury is typically associated with hypoxia-ischemia and/or infection/inflammation.
