Abstract:
It has been shown that a lot of diseases were related with the change or loss of Cl- channel functions. Among the Cl- channels, volume-regulated anion channel (VRAC) plays important roles in myocardial ischemia/reperfusion injury, cardiac arrhythmia and apoptosis; it may become a new target in the clinical treatment of heart diseases. This paper presents an overview of the physiological characteristics of VRAC and its relations with myocardial ischemia/reperfusion injury.
Insights

Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...
