Crosstalk Between Antioxidants and Adipogenesis: Mechanistic Pathways and Their Roles in Metabolic Health

Area of Science:

• Biochemistry
• Metabolic Health
• Cell Biology

Background:

• Oxidative stress and adipogenesis are linked to obesity and metabolic disorders.
• Reactive oxygen species (ROS) disrupt adipogenesis, leading to dysfunction, inflammation, and insulin resistance.

Purpose of the Study:

• To review the mechanistic pathways of antioxidant action in regulating oxidative stress and adipogenesis.
• To highlight the role of antioxidants in metabolic health and obesity prevention.

Main Methods:

• Literature review focusing on the interplay between oxidative stress, adipogenesis, and antioxidants.
• Analysis of endogenous and exogenous antioxidant mechanisms.
• Examination of signaling pathways and epigenetic regulation.

Main Results:

• Excessive ROS impairs adipogenesis by affecting key transcription factors (PPARγ, C/EBPα).
• Endogenous and exogenous antioxidants restore redox balance and adipocyte function.
• Exogenous antioxidants scavenge ROS, upregulate endogenous defenses, and modulate signaling pathways (NF-κB, PPARγ).
• Antioxidant-rich diets are associated with improved metabolic health and insulin sensitivity.

Conclusions:

• Antioxidants are vital in mitigating oxidative stress-induced adipocyte dysfunction and metabolic disorders.
• Dietary antioxidants and targeted therapies hold promise for enhancing metabolic health and managing obesity.
