MicroRNA Modulation by Dietary Supplements in Obesity

Area of Science:

• Metabolic disease research
• Nutritional science
• Molecular biology

Background:

• Obesity prevalence has surged globally, increasing morbidity and mortality.
• Diet and exercise are primary weight loss strategies, but adjuncts are sought.
• Dietary supplements (DSs), including plant compounds, are gaining interest for obesity management.

Purpose of the Study:

• To review the impact of plant-derived dietary supplements on microRNA expression in obesity.
• To explore how these supplements influence metabolic processes and weight management.

Main Methods:

• Review of preclinical and clinical studies on plant-derived DSs and obesity.
• Analysis of studies investigating microRNA expression changes.
• Focus on polyphenols, fatty acids, and other plant substances.

Main Results:

• Polyphenols modulate adipose tissue, reducing inflammation and improving insulin sensitivity.
• Plant-derived compounds alter microRNA profiles, reverting obesity-induced dysregulation.
• These alterations inhibit adipogenesis, promote weight loss, and ameliorate metabolic issues like insulin resistance and lipid anomalies.

Conclusions:

• Plant-derived DSs, via microRNA modulation, offer a promising strategy for obesity management.
• Targeting microRNA networks with these supplements may reverse key obesity-related metabolic dysfunctions.
• Further research supports their role in combating obesity and associated metabolic diseases.
