The role of micro-ribonucleic acid and small interfering-ribonucleic acid in precision nutrition for obesity management

Abstract

Background & aims: Precision nutrition aims to tailor dietary interventions based on genetic and molecular profiles. MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are emerging as critical tools in precision obesity management. miRNAs serve as biomarkers for predicting dietary response and obesity risk, while siRNAs provide a targeted approach to silencing obesity-related genes. This review explores the mechanisms, applications, and potential of integrating miRNA and siRNA in personalized dietary strategies to combat obesity.

Methods: A comprehensive literature review was conducted using Boolean operations to identify studies on miRNAs, siRNAs, and their roles in precision nutrition. The review focused on molecular mechanisms, clinical applications, challenges, and future directions in integrating miRNA detection and siRNA therapy for obesity management.

Results: miRNAs regulate gene expression related to lipid metabolism, adipogenesis, and insulin sensitivity, with miRNA-33 and miRNA-103/107 being notable examples. siRNAs offer precise gene silencing for targets like SREBP-1c and PPARγ, addressing metabolic pathways resistant to dietary interventions. The synergistic integration of miRNAs as biomarkers and siRNAs as therapeutic tools enhances the personalization and efficacy of obesity management.

Conclusions: The dual application of miRNAs and siRNAs in precision nutrition represents a transformative approach to obesity management. While challenges such as molecular stability and delivery systems persist, advancements in RNA technology and clinical research promise to revolutionize personalized dietary strategies. Future research should focus on large-scale trials and ethical considerations to ensure equitable and effective implementation.
