Mechanism of the defect in gap-junctional communication by expression of a connexin 26 mutant associated with dominant deafness.
Gap-junctional channels (connexin oligomers) are large-diameter aqueous pores formed by head-to-head association of two gap-junctional hemichannels, one from each of the adjacent cells. Profound hearing loss of genetic origin is common, and mutations of connexin 26 (Cx26) are the most frequent cause of this disorder. The Cx26 R75W mutant has been associated with disruption of cell-to-cell commu...
متن کامل"deafness –associated connexin 26 gene (gjb2) mutations in iranian population"
mutations in the gjb2 gene at the dfnb1 locus on chromosome 13q12 are associated with autosomal recessive non syndromic hearing loss (arnshl) in many populations. a single mutation, at position 35 (35delg) accounts for approximately 30-63% of mutations in white populations with a carrier frequency of 1.5-2.5% in most european, north american and mediterranean populations. in this study we have ...
متن کاملAberrant expression of connexin 26 is associated with lung metastasis of colorectal cancer.
PURPOSE Connexin 26 (Cx26) is one of the gap junction-forming family members classically considered to be tumor suppressors. However, recent studies show association of elevated expression of Cx26 with poor prognosis in several human malignancies. Furthermore, Cx26 has been observed to be indispensable to spontaneous metastasis of melanoma cells. Here, we assessed Cx26 expression in primary col...
متن کاملExpression of a connexin 43/beta-galactosidase fusion protein inhibits gap junctional communication in NIH3T3 cells
Gap junctions contain membrane channels that mediate the cell-to-cell movement of ions, metabolites and cell signaling molecules. As gap junctions are comprised of a hexameric array of connexin polypeptides, the expression of a mutant connexin polypeptide may exert a dominant negative effect on gap junctional communication. To examine this possibility, we constructed a connexin 43 (Cx43)/beta-g...
متن کاملInhibition of Connexin 26/43 and Extracellular-Regulated Kinase Protein Plays a Critical Role in Melatonin Facilitated Gap Junctional Intercellular Communication in Hydrogen Peroxide-Treated HaCaT Keratinocyte Cells
Though melatonin was known to regulate gap junctional intercellular communication (GJIC) in chick astrocytes and mouse hepatocytes, the underlying mechanism by melatonin was not elucidated in hydrogen peroxide- (H(2)O(2)-) treated HaCaT keratinocyte cells until now. In the current study, though melatonin at 2 mM and hydrogen peroxide (H(2)O(2)) at 300 μM showed weak cytotoxicity in HaCaT kerati...
