Dysrhythmia due to Verapamil Overdose in a Young Woman [PDF]

Case Reports in Cardiology
Verapamil (VER) is characterized as a calcium channel blocker (CCB) that can be intentionally or unintentionally overdosed. This drug, like other CCBs, inhibits the entry of calcium into vascular and myocardial tissues through L-type channels. VER exerts

Emerging roles of L-type voltage gated and other calcium channels in T lymphocytes.

Frontiers in Immunology, 2013
In T lymphocytes, calcium ion controls a variety of biological processes including development, survival, proliferation, and effector functions. These distinct and specific roles are regulated by different calcium signals, which are generated by various ...

Aging Alters the Formation and Functionality of Signaling Microdomains Between L-type Calcium Channels and β2-Adrenergic Receptors in Cardiac Pacemaker Cells

Frontiers in Physiology, 2022
Heart rate is accelerated to match physiological demands through the action of noradrenaline on the cardiac pacemaker. Noradrenaline is released from sympathetic terminals and activates β1-and β2-adrenergic receptors (ΑRs) located at the plasma membrane ...

The calmodulin-binding, short linear motif, NSCaTE is conserved in L-type channel ancestors of vertebrate Cav1.2 and Cav1.3 channels. [PDF]

PLoS ONE, 2013
NSCaTE is a short linear motif of (xWxxx(I or L)xxxx), composed of residues with a high helix-forming propensity within a mostly disordered N-terminus that is conserved in L-type calcium channels from protostome invertebrates to humans.

Calcium Channels in the Heart: Disease States and Drugs

Cells, 2022
Calcium ions are the major signaling ions in the cells. They regulate muscle contraction, neurotransmitter secretion, cell growth and migration, and the activity of several proteins including enzymes and ion channels and transporters. They participate in

Denitration of L‐type calcium channel [PDF]

FEBS Letters, 2008
Tyrosine nitration results in altered function of selective proteins, including human smooth muscle L‐type calcium channel, hCav1.2b. We report here that Cav1.2 is also subject to “denitration”. Cell lysates from activated macrophage‐like cell line, RAW264.7 cells, reversed peroxynitrite‐induced nitration of the carboxy terminus of Cav1.2 in a 1D gel ...

Intercommunication between Voltage-Gated Calcium Channels and Estrogen Receptor/Estrogen Signaling: Insights into Physiological and Pathological Conditions

Cells, 2022
Voltage-gated calcium channels (VGCCs) and estrogen receptors are important cellular proteins that have been shown to interact with each other across varied cells and tissues.

Forskolin Regulates L-Type Calcium Channel through Interaction between Actinin 4 and β3 Subunit in Osteoblasts. [PDF]

PLoS ONE, 2015
Voltage-dependent L-type calcium channels that permit cellular calcium influx are essential in calcium-mediated modulation of cellular signaling. Although the regulation of voltage-dependent L-type calcium channels is linked to many factors including ...

Potential binding modes of the gut bacterial metabolite, 5-hydroxyindole, to the intestinal L-type calcium channels and its impact on the microbiota in rats

Gut Microbes, 2023
Intestinal microbiota and microbiota-derived metabolites play a key role in regulating the host physiology. Recently, we have identified a gut-bacterial metabolite, namely 5-hydroxyindole, as a potent stimulant of intestinal motility via its modulation ...

Antihypertensive Effect of a Novel Angiotensin II Receptor Blocker Fluorophenyl Benzimidazole: Contribution of cGMP, Voltage-dependent Calcium Channels, and BKCa Channels to Vasorelaxant Mechanisms

Frontiers in Pharmacology, 2021
Background: The current study presents the novel angiotensin II receptor blocker fluorophenyl benzimidazole (FPD) as an antihypertensive agent in the SHR model of hypertension.
