Calcium cycling figures prominently in excitation-contraction coupling and in various signaling cascades involved in the development of left ventricular hypertrophy. We hypothesized that genetic suppression of the L-type calcium channel accessory beta-subunit would modulate calcium current and suppress cardiac hypertrophy. A short hairpin RNA template sequence capable of mediating the knockdown...
We previously reported the small organic N-type calcium channel blocker NP078585 that while efficacious in animal models for pain, exhibited modest L-type calcium channel selectivity and substantial off-target inhibition against the hERG potassium channel. Structure-activity studies to optimize NP078585 preclinical properties resulted in compound 16, which maintained high potency for N-type cal...
Calcium channel blockers are widely used in the treatment of cardiovascular disorders for their actions on the voltage sensitive calcium channels in cardiac and smooth muscles. The reorganization on calcium channel antagonist binding sites in the limbic regions of the brain, raises the hope that these might also be helpful in some behavioural disorders. Calcium channel blockers act by blocking ...
The dihydropyridine-sensitive calcium channel of the rabbit skeletal muscle is the first voltage-gated calcium channel which has been purified and biochemically characterized. The alpha 1-subunit, a 165 kDa protein, of the purified dihydropyridine receptor contains all regulatory sites of a L-type calcium channel and the calcium conducting unit. The purpose of this review is to summarize and di...
Rad, Gem/Kir, Rem, and Rem2 are members of the Ras-related RGK (Rad, Gem, and Kir) family of small GTP-binding proteins. Heterologous expression of RGK proteins interferes with de novo calcium channel assembly/trafficking and dramatically decreases the amplitude of currents arising from preexisting high-voltage-activated calcium channels. These effects probably result from the direct interactio...
Atrial fibrillation (AF) is the most common sustained arrhythmia causing high morbidity and mortality. While changing of the cellular calcium homeostasis plays a critical role in AF, the L-type calcium channel α1c protein has suggested as an important regulator of reentrant spiral dynamics and is a major component of AF-related electrical remodeling. Our computational modeling predicted that mi...
