Calcium (Ca2+) signaling is vital for heart function. This review explores how calcium-related microRNAs (miRNAs) impact heart diseases like hypertrophy and heart failure, offering potential therapeutic targets.

Area of Science:

  • Cardiovascular Biology
  • Molecular Cardiology
  • Gene Regulation

Background:

  • Calcium (Ca2+) signaling is essential for cardiac muscle contraction, electrical activity, and cell growth.
  • Dysregulation of Ca2+ handling proteins is a hallmark of heart disease.
  • MicroRNAs (miRNAs) are key regulators of gene expression, influencing cardiac Ca2+ cycling.

Purpose of the Study:

  • To review the role of cardiac Ca2+ signaling in pathological conditions.
  • To summarize the involvement of Ca2+-related miRNAs in heart diseases.
  • To discuss the therapeutic potential of miRNAs targeting Ca2+ handling.

Main Methods:

  • Literature review of studies on cardiac Ca2+ signaling.
  • Analysis of research on miRNAs in cardiac hypertrophy, heart failure, myocardial infarction, and atrial fibrillation.
  • Synthesis of findings on miRNA-mediated regulation of Ca2+ handling.

Main Results:

  • Impaired Ca2+ handling is central to various heart diseases.
  • Specific miRNAs are implicated in the pathophysiology of cardiac hypertrophy, heart failure, myocardial infarction, and atrial fibrillation.
  • Ca2+-related miRNAs represent promising biomarkers and therapeutic targets.

Conclusions:

  • Cardiac Ca2+ signaling is critically regulated by miRNAs.

Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Antihypertensive Drugs: Action of Calcium Channel Blockers

Calcium ions are essential to contract smooth muscle cells in blood vessels. They enter these cells through voltage-dependent calcium channels, specifically L-type calcium channels in the cell membrane. These L-type calcium channels are integral to the excitation-contraction coupling process in smooth muscle. When a stimulus is received by smooth muscle cells, their membrane depolarizes. This alteration in membrane potential instigates the opening of L-type calcium channels. As a result,...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
