New insights into the role of mitochondrial dynamics in oxidative stress-induced diseases

Area of Science:

• Biochemistry
• Cell Biology
• Pathology

Background:

• Reactive oxygen species (ROS) accumulation causes oxidative stress (OS), leading to cellular damage like DNA mutations and lipid peroxidation.
• OS is linked to aging and diseases such as diabetes, cardiovascular, and neurodegenerative disorders.
• Mitochondria are key ROS producers and their dysfunction (e.g., altered dynamics, OS) is implicated in various pathologies.

Purpose of the Study:

• To review recent advances in oxidative stress-induced mitochondrial dynamics.
• To discuss diseases associated with OS-induced mitochondrial damage.
• To summarize signaling pathways regulating OS and mitochondrial dynamics and explore therapeutic interventions.

Main Methods:

• Literature review focusing on recent research.
• Synthesis of information on oxidative stress, mitochondrial dynamics, and disease.
• Analysis of signaling pathways and therapeutic approaches.

Main Results:

• Oxidative stress significantly impacts mitochondrial dynamics, including fission, fusion, and mitophagy.
• Mitochondrial dysfunction driven by OS contributes to the pathogenesis of aging and various chronic diseases.
• Specific signaling pathways mediate the interplay between OS and mitochondrial health.

Conclusions:

• Understanding OS-induced mitochondrial dynamics is crucial for comprehending disease mechanisms.
• Targeting mitochondrial dynamics offers potential therapeutic avenues for oxidative stress-related disorders.
• Further research into therapeutic strategies is warranted to mitigate mitochondrial damage from OS.
