Connexin Genes in the Mouse and Human Genome
Cell Communication and Adhesion, 2001 Gap junctions serve for direct intercellular communication by docking of two hemichannels in adjacent cells thereby forming conduits between the cytoplasmic compartments of adjacent cells. Connexin genes code for subunit proteins of gap junction channels

Connexins are essential in the propagation of electrical activity throughout the heart and are an important determinant of conduction velocity. Their dysfunction is an important factor in the genesis of abnormal cardiac rhythm and is relevant to the pathogenesis of a wide variety of cardiac pathologies. Here, we review the basic biology of connexins in

Connexins are mechanosensitive
American Journal of Physiology-Cell Physiology, 2004Connexins form gap junction channels that provide a hydrophilic path between cell interiors. Some connexins, particularly the lens connexins, Cx46 and Cx50 and their orthologs, can form functional hemichannels in nonjunctional membranes. These hemichannels are a nonselective conduit to the extracellular medium and may jeopardize cell survival.

Summry— Connexin channels clustered at gap junctions are obligatory attributes of all macroscopic endocrine and exocrine glands investigated so far and also connect most types of cells which produce secretory products in other tissues. Increasing evidence indicates that connexins, and the cell‐to‐cell communications that these proteins permit ...

Summry— The hypothesis, that gap junctional intercellular communication plays a key role in carcinogenesis and more generally in growth control was formulated nearly 40 years ago. From this time, data accumulated, showing that this type of communication is frequently decreased or absent in cells treated with tumor promoting agents, among transformed ...

Trends in Cardiovascular Medicine, 1992
Gap junctions are specialized regions of adjoining cell membranes composed of numerous intercellular low-resistance channels. In the heart, these channels electrotonically couple adjacent myocytes and synchronize the cardiac action potential. Signaling through gap junction channels may also influence embryogenesis and development.

Remodeling of the vascular wall plays a central role in many physiological processes, but also in the pathogenesis of cardiovascular diseases such as atherosclerosis and restenosis. Atherosclerosis represents the major cause of death and disability in adult populations of Western societies.

Connexins and Cardiac Arrhythmias
2006During cardiac remodeling, impulse conduction in the heart is altered by changes in excitability, electrical coupling, and tissue architecture. The impairment of normal impulse conduction is one of the factors that increases the propensity for arrhythmias. This chapter focuses on the relationship between electrical coupling between ventricular myocytes

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 ...

Connexin-30 Deletion Analysis in Connexin-26 Heterozygotes
Genetic Testing, 2003Mutations in the Connexin-26 gene (Cx 26, GJB2) are the most common cause of hereditary nonsyndromic sensorineural hearing loss (SNHL). DNA analysis of the Cx 26 gene in deaf or hard-of-hearing individuals frequently demonstrates heterozygosity despite the fact that most mutations are known to be recessive. A 342-kb deletion in a gene adjacent to Cx 26,
