Advances in the Mechanism of ceRNA Regulation in Postoperative Cognitive Dysfunction

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• Postoperative cognitive dysfunction (POCD) is a frequent neurological complication in older surgical patients, impacting memory, attention, and personality.
• Current treatments for POCD are limited, highlighting the need for novel therapeutic strategies and a deeper understanding of its underlying molecular mechanisms.

Purpose of the Study:

• This review aims to elucidate the role of non-coding RNAs (ncRNAs) and the competing endogenous RNA (ceRNA) mechanism in the pathogenesis of POCD.
• To provide a foundation for future research into mechanistic exploration and the development of targeted therapies for POCD.

Main Methods:

• A comprehensive review of existing scientific literature on ncRNAs, ceRNA networks, and their involvement in POCD.
• Analysis of emerging evidence linking ceRNA-mediated regulatory pathways to POCD development and progression.

Main Results:

• Non-coding RNAs are crucial regulators of neuronal complexity and synaptic function in the central nervous system.
• The ceRNA mechanism, where ncRNAs modulate microRNA (miRNA) activity, is implicated in the gene expression dysregulation observed in POCD.

Conclusions:

• ceRNA regulatory networks represent a promising area for understanding POCD pathogenesis.
• Targeting ncRNA-mediated ceRNA pathways offers potential for developing novel therapeutic interventions for postoperative cognitive dysfunction.
