miRNA, phytometabolites and disease: Connecting the dots

Area of Science:

• Biochemistry
• Molecular Biology
• Genetics

Background:

• MicroRNAs (miRNAs) are key regulators of gene expression in eukaryotes, controlling diverse developmental processes.
• Dysregulated miRNAs are linked to various human diseases, driving interest in miRNA-based therapeutics.
• Medicinal plants contain bioactive metabolites with therapeutic potential, and miRNAs regulate plant metabolic pathways.

Purpose of the Study:

• To review the medicinal and gene regulatory properties of plant secondary metabolites.
• To explore the regulation of plant miRNAs by metabolites and their cross-kingdom effects on human miRNAs.
• To discuss the implications for developing miRNA-based therapies.

Main Methods:

• Literature review of studies on miRNA function, plant metabolites, and cross-kingdom gene regulation.
• Analysis of experimental evidence linking plant metabolites to human miRNA activity.
• Synthesis of information on miRNA-mediated regulation in plants and humans.

Main Results:

• Plant secondary metabolites can potentially cross-regulate human miRNAs and transcripts, offering therapeutic avenues.
• miRNAs play a role in regulating metabolic pathways within plants.
• Cross-kingdom gene regulation by plant-derived compounds is an emerging area with ongoing validation efforts.

Conclusions:

• Understanding the interplay between plant miRNAs, metabolites, and human miRNAs is crucial for novel therapeutic strategies.
• Further research and clinical validation are necessary to confirm the efficacy and reproducibility of these findings.
• Synthetic or artificial miRNAs derived from plant metabolite interactions hold promise for future health benefits.
