The role of microRNA in nutritional control

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• MicroRNAs (miRNAs) are noncoding RNAs regulating diverse metabolic processes like differentiation, proliferation, and apoptosis.
• Complex regulatory mechanisms, including small interfering RNAs and metabolites, control miRNA generation, contributing to organismal complexity.
• Non-protein-coding DNA, including miRNAs, is crucial for evolutionary development and metabolic control.

Purpose of the Study:

• To review the role of intracellular and extracellular miRNAs in nutritional control of physiological and pathological processes.
• To update on recent findings presented at the 25th Marabou Symposium on miRNA's role in health and nutrition.

Main Methods:

• Literature review and synthesis of presentations from an international symposium.
• Discussion of current research on miRNA processing, function, and clinical applications.

Main Results:

• miRNA processing defects are linked to congenital abnormalities, with therapeutic potential for disease manipulation.
• Extracellular miRNAs packaged in vesicles facilitate intercellular communication.
• Bloodstream-circulating extracellular miRNAs serve as potential biomarkers for cancer diagnosis, metastasis assessment, and prognosis.

Conclusions:

• miRNAs play a significant role in nutritional control and overall health.
• Targeting miRNA pathways offers potential therapeutic strategies for various diseases.
• Extracellular miRNAs represent a promising avenue for cancer diagnostics and prognostics.
