Oxidative Stress and MicroRNAs in Endothelial Cells under Metabolic Disorders

Area of Science:

• Biochemistry
• Molecular Biology
• Cardiovascular Science

Background:

• Reactive oxygen species (ROS) act as signaling molecules but excessive accumulation leads to oxidative stress and endothelial cell (EC) dysfunction.
• EC dysfunction promotes a pro-coagulative and proinflammatory state, elevating risks for cardiovascular (CV) and metabolic disorders.
• MicroRNAs are investigated for their role in co-regulating ROS and potentially treating CV risk factors.

Purpose of the Study:

• To review ROS generation and pathways.
• To discuss EC physiology and ROS-induced dysfunction.
• To explore the link between metabolic disorders and oxidative stress.
• To examine microRNA-based therapeutic strategies for oxidative stress and ROS control in vascular health.

Main Methods:

• Literature review of ROS pathways and generation.
• Analysis of endothelial cell physiology and dysfunction mechanisms.
• Examination of current research on metabolic disorders and oxidative stress.
• Review of microRNA functions in ROS regulation and therapeutic potential.

Main Results:

• ROS accumulation beyond antioxidant capacity causes oxidative stress and EC dysfunction.
• Dysfunctional ECs contribute to a pro-thrombotic and inflammatory vascular environment.
• Oxidative stress is implicated in common metabolic disorders.
• MicroRNAs play a crucial role in co-regulating ROS levels.

Conclusions:

• Understanding ROS generation mechanisms is key to protecting EC function.
• Targeting ROS through microRNA manipulation offers a potential therapeutic strategy for vascular disorders.
• Comprehensive knowledge of ROS pathways and microRNA regulation can prevent cardiovascular and metabolic diseases.
