Insights
Oxidative stress from reactive oxygen species (ROS) damages cells and impairs protein synthesis, contributing to cardiovascular diseases (CVDs). This review explores the link between protein translation, ROS, and heart and blood vessel disorders.
Area of Science:
- Cardiovascular Science
- Molecular Biology
- Oxidative Stress Research
Background:
- Cardiovascular diseases (CVDs) are the leading global cause of mortality, driven by complex multifactorial origins.
- Acute oxidative stress, marked by elevated reactive oxygen species (ROS), is a key factor in CVD development and progression.
- ROS can inflict cellular damage and disrupt essential processes like protein synthesis, leading to faulty proteins and disturbed protein homeostasis.
Purpose of the Study:
- To examine the intricate relationships between translational dysregulation, oxidative stress (ROS), and the pathogenesis of cardiovascular disorders.
- To elucidate the molecular mechanisms linking protein synthesis defects to heart and blood vessel pathologies.
Main Methods:
- This review synthesizes existing literature on oxidative stress, protein translation, and cardiovascular disease.
- Analysis of molecular pathways connecting ROS-induced cellular damage to protein synthesis dysfunction.
- Examination of studies investigating translational control in the context of cardiovascular pathologies.
Main Results:
- Elevated ROS levels directly impair protein synthesis machinery and lead to the production of aberrant proteins.
- Disruptions in protein homeostasis due to translational dysregulation are implicated in the progression of CVDs.
- Specific molecular alterations in protein translation are identified as contributors to heart and blood vessel diseases.
Conclusions:
- Understanding the interplay between ROS and protein translation is critical for developing novel therapeutic strategies for CVDs.
- Targeting translational dysregulation offers a promising avenue for mitigating oxidative stress-induced cardiovascular damage.
- Further research into these molecular links can pave the way for effective prevention and treatment of cardiovascular diseases.
Abstract:
Cardiovascular diseases (CVDs) are a group of disorders that affect the heart and blood vessels. Due to their multifactorial nature and wide variation, CVDs are the leading cause of death worldwide. Understanding the molecular alterations leading to the development of heart and vessel pathologies is crucial for successfully treating and preventing CVDs. One of the causative factors of CVD etiology and progression is acute oxidative stress, a toxic condition characterized by elevated intracellular levels of reactive oxygen species (ROS). Left unabated, ROS can damage virtually any cellular component and affect essential biological processes, including protein synthesis. Defective or insufficient protein translation results in production of faulty protein products and disturbances of protein homeostasis, thus promoting pathologies. The relationships between translational dysregulation, ROS, and cardiovascular disorders will be examined in this review.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
