T-type calcium channel: a privileged gate for calcium entry and control of adrenal steroidogenesis
Intracellular calcium plays a crucial role in modulating a variety of functions such as muscle contraction, hormone secretion, gene expression or cell growth. Calcium signaling has been however shown to be more complex than initially thought.

Low voltage activation of KCa1.1 current by Cav3-KCa1.1 complexes. [PDF]
Calcium-activated potassium channels of the KCa1.1 class are known to regulate repolarization of action potential discharge through a molecular association with high voltage-activated calcium channels.

Store-operated calcium channels in skin
The skin is a complex organ that acts as a protective layer against the external environment. It protects the internal tissues from harmful agents, dehydration, ultraviolet radiation and physical injury as well as conferring thermoregulatory control ...

Mounting in vitro, in vivo and clinical evidence suggest an important role for filopodia in driving cancer cell invasion. Using a high-throughput microscopic-based drug screen, we identify FDA-approved calcium channel blockers (CCBs) as potent inhibitors

Tuned calcium entry through voltage-gated calcium channels is a key requirement for many cellular functions. This is ensured by channel gates which open during membrane depolarizations and seal the pore at rest. The gating process is determined by distinct sub-processes: movement of voltage-sensing domains (charged S4 segments) as well as opening and ...

Suramin-Induced Neurotoxicity: Preclinical Models and Neuroprotective Strategies
Suramin is a trypan blue analogon originally developed to treat protozoan infections, which was found to have diverse antitumor effects. One of the most severe side effects in clinical trials was the development of a peripheral sensory-motor ...

The regulation role of calcium channels in mammalian sperm function: a narrative review with a focus on humans and mice [PDF]
Mammalian sperm are characterized as specialized cells, as their transcriptional and translational processes are largely inactive. Emerging researches indicate that Ca2+ serves as a crucial second messenger in the modulation of various sperm ...

Overdose of calcium channel blockers is potentially lethal. Verapamil and diltiazem are much more dangerous than dihydropyridines. Hypotension with (verapamil and diltiazem) or without (dihydropyridines) heart block and bradycardia are the most important features.

The involvement of actin, calcium channels and exocytosis proteins in somato-dendritic oxytocin and vasopressin release [PDF]
Hypothalamic magnocellular neurons release vasopressin and oxytocin not only from their axon terminals into the blood, but also from their somata and dendrites into the extracellular space of the brain, and this can be regulated independently ...

This chapter focuses on calcium movements and their impact on exocytosis in adrenal medullary chromaffin cells (CCs). Upon depolarization, Ca2+ enters the cell through open plasmalemmal voltage-dependent calcium channels (Cav channels) driven by a large ...
