Adipose Tissue Dysfunction in Obesity: Role of Mineralocorticoid Receptor

Area of Science:

• Endocrinology
• Metabolic Syndrome
• Cardiovascular Disease

Background:

• The mineralocorticoid receptor (MR) is crucial for blood pressure and electrolyte balance.
• Emerging evidence links MR to inflammation, oxidative stress, and fibrosis in organs like adipose tissue.
• Overexpressed MR in obesity suggests a role in adipokine dysregulation and chronic inflammation.

Purpose of the Study:

• To review mechanisms of MR activation in adipose tissue dysfunction in obesity.
• To explore the potential benefits of MR antagonists (MRAs) in this context.

Main Methods:

• Literature review of studies on MR, obesity, and adipose tissue.
• Analysis of animal models investigating MRAs for metabolic alterations.
• Focus on mechanistic insights into MR's role in obesity-related adipose tissue changes.

Main Results:

• MR activation in adipose tissue is implicated in pro-inflammatory, pro-oxidative, and pro-fibrotic changes.
• Obesity is associated with MR overexpression in adipose tissue, contributing to metabolic dysfunction.
• MRAs have shown promise in animal models for preventing obesity-related metabolic disturbances.

Conclusions:

• MR plays a significant role in adipose tissue dysfunction and associated complications in obesity.
• MR antagonists represent a potential therapeutic strategy for managing obesity-related metabolic and cardiovascular issues.
