Insights

Circular RNAs (circRNAs) regulate programmed cell death (PCD) in cardiovascular diseases (CVDs). This review highlights circRNAs as potential diagnostic and therapeutic targets for heart conditions.

Area of Science:

  • Cardiovascular Research
  • Molecular Biology
  • Genetics

Background:

  • Cardiovascular diseases (CVDs) are a leading global health issue.
  • Programmed cell death (PCD) pathways are critical in myocardial injury.
  • Circular RNAs (circRNAs) are emerging regulators of cardiomyocyte fate.

Purpose of the Study:

  • To review the role of circRNAs in modulating PCD in CVDs.
  • To explore circRNA-based diagnostics and therapeutics for CVDs.
  • To discuss future clinical translation strategies for circRNA research.

Main Methods:

  • Literature review synthesizing current research on circRNAs and PCD in CVDs.
  • Analysis of circRNA mechanisms including molecular sponging, protein interactions, and epigenetic regulation.
  • Evaluation of diagnostic and therapeutic applications of circRNAs.

Main Results:

  • CircRNAs act as key regulators of multiple PCD pathways (ferroptosis, apoptosis, pyroptosis, autophagy, necroptosis) in the heart.
  • CircRNA expression patterns can be used for CVD stratification with high accuracy.
  • Protective circRNAs delivered via viral vectors show efficacy in preclinical models of myocardial infarction.
  • CRISPR-based editing and nanoplatforms show promise for circRNA-based therapies.

Conclusions:

  • CircRNA networks represent promising theranostic targets for CVDs.
  • Context-dependent circRNA functions and pathway crosstalk require further investigation.
  • Tissue-specific delivery remains a challenge for clinical translation of circRNA therapies.

Translational Regulation

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

Negative Regulator Molecules01:23

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

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...

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...

Improving Translational Accuracy02:07

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...
