The gap junction protein connexin-43 is normally located at the intercalated discs of cardiac myocytes, and it plays a critical role in the synchronization of their contraction. The mechanism by which connexin-43 is localized within cardiac myocytes is unknown. However, localization of connexin-43 likely involves an interaction with the cytoskeleton; immunofluorescence microscopy showed that in...
OBJECTIVE To test the hypothesis that atrial fibrillation (AF) is associated with changes in the expression of connexins 40 and 43 in the left atrium with more pronounced changes in mitral valve disease than in lone AF. METHODS Protein concentrations of connexin 40 and connexin 43 were analysed in left atrial tissue of patients undergoing cardiac surgery. One group of patients had lone AF (n ...

M utations in connexin 26 (GJB2, Cx26) cause autosomal recessive and occasionally dominant non-syndromic sensorineural hearing loss (SNHL). Cx26 mutations have also been identified in SNHL with dermatological features of autosomal dominant diffuse palmoplantar hyperkeratosis (DPPK). We describe a girl with bilateral sloping sensorineural hearing loss, striate palmoplantar hyperkeratosis (SPPK),...
Ca2+ signaling has been implicated in the initial pathophysiologic mechanisms underlying the cochlea's response to acoustic overstimulation. Intracellular Ca2+ signaling (ICS) waves, which occur in glia and retinal cells in response to injury to activate cell regulatory pathways, have been proposed as an early event in cochlear injury. Disruption of ICS activity is thought to underlie Connexin ...
