Connexin 43 hemichannels and related diseases. [PDF]
Antib TherAbstract Connexin 43 (Cx43) protein forms hemichannels (connexons) and gap junctions, with hemichannels consisting of six Cx43 molecules and gap junctions formed by two hemichannels. While gap junctions are prevalent in organs like the heart and liver, hemichannels are found in specific cell types, such as astrocytes and osteocytes ...

Connexin 43 Hemichannels Are Permeable to ATP [PDF]
The Journal of Neuroscience, 2008 Astrocytes are electrically nonexcitable cells that communicate by means of Ca2+signaling. Long-distance intercellular Ca2+waves are initiated by release of ATP and activation of purinergic receptors on nearby cells. Previous studies have implicated connexin 43 (Cx43) in ATP release, but definitive proof that ATP exits through Cx43 hemichannels does ...

Connexin 43 confers chemoresistance through activating PI3K
Oncogenesis, 2022 Circumventing chemoresistance is crucial for effectively treating cancer including glioblastoma, a lethal brain cancer. The gap junction protein connexin 43 (Cx43) renders glioblastoma resistant to chemotherapy; however, targeting Cx43 is difficult ...

Connexin-43-dependent ATP release mediates macrophage activation during sepsis
eLife, 2019 Bacterial spillage into a sterile environment following intestinal hollow-organ perforation leads to peritonitis and fulminant sepsis. Outcome of sepsis critically depends on macrophage activation by extracellular ATP-release and associated autocrine ...

Connexin 43 Hemichannels Regulate Osteoblast to Osteocyte Differentiation
Frontiers in Cell and Developmental Biology, 2022 Connexin 43 (Cx43) is the predominant connexin subtype expressed in osteocytes. Osteocytes, accounting for 90%–95% of total bone cells, function as orchestrators coordinating balanced activity between bone-resorbing osteoclasts and bone-forming ...

Internal translation of the connexin 43 transcript [PDF]
Cell Communication and Signaling, 2014 Connexin 43 (Cx43), the most widely expressed gap junction protein, is associated with a number of physiological and pathological conditions. Many functions of Cx43 have been shown to be independent of gap junction formation and only require the expression of Cx43 C-terminal fragments.

Connexin 43: An Interface Connecting Neuroinflammation to Depression
Molecules, 2023 Major depressive disorder (MDD) is a leading chronic mental illness worldwide, characterized by anhedonia, pessimism and even suicidal thoughts. Connexin 43 (Cx43), mainly distributed in astrocytes of the brain, is by far the most widely and ubiquitously
