Study on the Relationship between the miRNA-centered ceRNA Regulatory Network and Fatigue

Area of Science:

• Genetics
• Molecular Biology
• Neuroscience

Background:

• Fatigue incidence is rising, necessitating urgent prevention and treatment strategies.
• Genetic research into fatigue is a growing field, with transcriptome-level regulation being a key focus.
• Noncoding RNAs (ncRNAs), including miRNAs, lncRNAs, and circRNAs, play significant roles in gene regulation.

Purpose of the Study:

• To review the relationship between ncRNAs (miRNAs, lncRNAs, circRNAs) and fatigue.
• To explore the regulatory role of the miRNA-centered competing endogenous RNA (ceRNA) network in fatigue.
• To provide a comprehensive understanding of the genetic regulatory network underlying fatigue.

Main Methods:

• Literature review summarizing current research on ncRNAs and fatigue.
• Analysis of the mechanisms by which miRNAs, lncRNAs, and circRNAs influence fatigue.
• Focus on the ceRNA hypothesis and its implications for fatigue pathogenesis.

Main Results:

• MiRNAs are involved in regulating CNS immune responses, nerve impulse transmission, and energy metabolism in fatigue.
• LncRNAs can modulate dopaminergic neurons, potentially aiding in chronic fatigue syndrome (CFS) diagnosis.
• CircRNAs participate in fatigue by regulating pathways like NF-κB, TNF-α, and IL-1β.

Conclusions:

• The miRNA-centered ceRNA regulatory network is closely linked to fatigue development.
• Further research into ncRNA-based fatigue mechanisms, particularly ceRNA networks, is significant.
• Understanding these complex genetic interactions is crucial for novel fatigue diagnostics and therapeutics.
