Abstract:
Since the discovery of the participation of various ion channels in the regulation of cell proliferation and programmed cell death two decades ago, the field exploring ion channel function in relation to cancer has undergone rapid development. Although the mechanisms accounting for the impact of ion channel modulators on cancer growth have not been fully clarified in all cases, numerous in vivo experiments targeting diverse ion channels in various cancer models illustrate the great potentiality of this approach and promote ion channels to the class of oncological targets. In the present review we give an updated overview of the field and critically discuss the promising results obtained in pre-clinical models using specific pharmacological modulators of calcium, sodium, potassium and anion-permeable ion channels, whose expression is often altered in tumor cells and tissues. The most, especially critical issues are specificity of action and side-effects. Interestingly, some of the most potent drugs are natural products, and several of the active compounds are already used in the clinic for other purposes. In these latter cases involving drug repositioning we may expect a faster progression from preclinical to clinical studies. This article is part of a Special Issue entitled: Calcium and Cell Fate. Guest Editors: Jacques Haiech, Claus Heizmann, Joachim Krebs, Thierry Capiod and Olivier Mignen.

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...

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
