Insights
Stress granules (SG) play a key role in atherosclerosis, a cardiovascular disease. Understanding SG formation and dynamics offers new therapeutic targets for preventing and treating atherosclerosis.
Area of Science:
- Cellular biology
- Molecular medicine
- Cardiovascular research
Background:
- Atherosclerosis is a major cause of cardiovascular disease, driven by inflammation and metabolic dysfunction.
- Stress granules (SG) are cellular aggregates forming under stress, with emerging links to disease.
- The precise role of SG in atherosclerosis pathogenesis remains incompletely understood.
Purpose of the Study:
- To comprehensively analyze the role of stress granules in atherosclerosis development.
- To investigate how cellular stresses and atherosclerosis-associated factors influence SG formation.
- To explore the impact of SG dynamics on pro-atherogenic processes.
Main Methods:
- Review and analysis of existing literature on stress granules and atherosclerosis.
- Examination of cellular stress responses and their components in SG formation.
- Assessment of how factors like inflammation, shear stress, and oxidative stress affect SG.
- Evaluation of SG dynamics' influence on endothelial dysfunction, lipid metabolism, and immune cell recruitment.
Main Results:
- Cellular stresses stimulate SG formation, involving specific components and regulatory genes.
- Atherosclerosis-related factors (inflammation, OSS, OS) modulate SG formation.
- Altered SG dynamics impact key pro-atherogenic processes, including endothelial dysfunction and immune responses.
- SG are implicated in lipid metabolism alterations within the context of atherosclerosis.
Conclusions:
- There is a complex interplay between stress granules and atherosclerosis.
- Understanding this relationship may reveal novel therapeutic strategies for cardiovascular diseases.
- Targeting SG dynamics presents a promising avenue for future atherosclerosis treatments.
Abstract:
Atherosclerosis, a complex inflammatory and metabolic disorder, is the underlying cause of several life-threatening cardiovascular diseases. Stress granules (SG) are biomolecular condensates composed of proteins and mRNA that form in response to stress. Recent studies suggest a potential link between SG and atherosclerosis development. However, there remain gaps in understanding SG role in atherosclerosis development. Here we provide a thorough analysis of the role of SG in atherosclerosis, covering cellular stresses stimulation, core components, and regulatory genes in SG formation. Furthermore, we explore atherosclerosis induced factors such as inflammation, low or oscillatory shear stress (OSS), and oxidative stress (OS) may impact SG formation and then the development of atherosclerotic lesions. We have assessed how changes in SG dynamics impact pro-atherogenic processes like endothelial dysfunction, lipid metabolism, and immune cell recruitment in atherosclerosis. In summary, this review emphasizes the complex interplay between SG and atherosclerosis that could open innovative directions for targeted therapeutic strategies in preventing or treating atherosclerotic cardiovascular diseases.
