Insights

MicroRNAs (miRNAs) are key regulators of cardiovascular disease. This review details how miRNAs control cardiomyocyte death, including apoptosis, necrosis, and autophagy, in conditions like heart failure and myocardial infarction.

Area of Science:

  • Cardiovascular Biology
  • Molecular Biology
  • Cell Death Mechanisms

Background:

  • MicroRNAs (miRNAs) are critical regulators in cardiovascular pathophysiology.
  • Cardiomyocyte death is a central mechanism in various heart diseases, including myocardial infarction and heart failure.
  • Understanding miRNA-mediated regulation of cell death pathways is vital for therapeutic development.

Purpose of the Study:

  • To provide a comprehensive overview of the functional roles of miRNAs in regulating cardiomyocyte death.
  • To systematically review the involvement of miRNAs in apoptosis, necrosis, and autophagy in the context of cardiovascular disease.
  • To highlight the significance of miRNA-mediated cardiomyocyte death in acute myocardial infarction, ischemia/reperfusion injury, and heart failure.

Main Methods:

  • Systematic literature review.
  • Analysis of existing research on miRNA function in cardiomyocyte death.
  • Focus on apoptosis, necrosis, and autophagy pathways.

Main Results:

  • miRNAs extensively regulate multiple cardiomyocyte death pathways.
  • Specific miRNAs have been identified as key players in apoptosis, necrosis, and autophagy.
  • Dysregulation of these miRNAs contributes to the progression of cardiovascular diseases.

Conclusions:

  • miRNAs are pivotal in controlling cardiomyocyte fate during cardiovascular insults.
  • Targeting specific miRNAs offers potential therapeutic strategies for managing heart failure and myocardial infarction.
  • Further research into miRNA-mediated cell death mechanisms is warranted for novel treatment development.

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...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Caspases01:24

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...
