Expression of connexin 26 and connexin 43 is reduced in Hirschsprung's disease
Journal of Surgical Research, 2016Despite having an optimal pull-through operation, some children with Hirschsprung's disease (HSCR) continue to experience persistent bowel symptoms. Coordinated colonic electrical activity depends on intercellular communication between the enteric nerves, interstitial cells of Cajal (ICCs), smooth muscle cells, and fibroblast-like (platelet-derived ...

Connexin 43 is localized with actin in tenocytes
Cell Motility, 2006AbstractVarieties of cell–matrix or cell–cell adhesions are associated with the actin cytoskeleton. However, for gap junctions, which are both channels and adhesions, there has been little evidence for such an association. The purpose of this study was to determine if connexin 43 (Cx43) associates with actin and to determine if this association is ...

Characterization of connexin 30.3 and 43 in thymocytes
Immunology Letters, 2004During maturation, thymocytes interact directly and indirectly with different cell types of the thymic microenvironment. Such a cellular communication has been basically ascribed to soluble factors and surface receptors. However, little attention has been given to cellular communication mediated by gap junctions.

Connexin 43 in ischemic pre- and postconditioning
Heart Failure Reviews, 2007Connexin 43 (Cx43) is the predominant protein forming gap junctions and non-junctional hemichannels in ventricular myocardium, but Cx43 is also localized at the inner membrane of cardiomyocyte mitochondria. In cardiomyocytes, Cx43 is involved in the formation of reactive oxygen species, which are central to the signal transduction cascade of ischemic ...

Role of connexin 43 in cardiovascular diseases
European Journal of Pharmacology, 2015Gap junctions (GJs) channels provide the basis for intercellular communication in the cardiovascular system for maintenance of the normal cardiac rhythm, regulation of vascular tone and endothelial function as well as metabolic interchange between the cells. They allow the transfer of small molecules and may enable slow calcium wave spreading, transfer

Biochimie, 2010
The role of gap junctions in proliferation, differentiation and apoptosis has been recently highlighted. Nevertheless, the molecular mechanisms that control these physiological events by acting on gap junction channels are still unknown. We have recently demonstrated that heteromeric gap junction plaques composed by Cx43 and Cx33 are unstable at the ...

Glomerular expression of connexin 40 and connexin 43 in rat experimental glomerulonephritis
Clinical and Experimental Nephrology, 2012Gap junctional intercellular communication is thought to play an important role in the maintenance of cell differentiation and homeostasis. Gap junctions connect glomerular mesangial cells to each other. In this study, we examined the glomerular expression of connexins (Cxs) 40 and 43 at both the protein and transcript levels in anti-Thy1.1 ...

Posttranscriptional regulation of connexin-43 expression
Archives of Biochemistry and Biophysics, 2012Posttranscriptional regulation of the biosynthesis of connexins, the building blocks of gap junctional channels, may occur by modulation of connexin mRNA stability and translation. To date, few RNA binding proteins and micro-RNAs (miRNAs) affecting connexin expression are known.

To determine the distribution of gap junction protein connexin 43 (Cx43) and the expression of Cx43 mRNA in different regions of canine small intestine and colon, modified Western blot and Northern blot techniques were used with a site-directed antibody raised against a synthetic peptide of Cx43 Anti-Cx43 (252-271) and a probe of 1.3-kb Cx43 cDNA ...

Endothelial Connexin 37, Connexin 40, and Connexin 43 Respond Uniquely to Substrate and Shear Stress
Endothelium, 2007Endothelial connexins have been linked to atherosclerosis and hypertension; however, little is know about their sensitivity to stimuli and individual functions. This study investigates the responses of endothelial connexin 37, connexin 40, and connexin 43 (Cx37, Cx40, and Cx43) to shear stress and substrate.
