Abstract:
Postoperative cognitive dysfunction (POCD) is a significant complication following surgery. The precise mechanisms underlying POCD remain elusive, although it is speculated that they involve central nervous system inflammation, oxidative stress and cellular apoptosis. MicroRNAs (miRNAs), a class of non-coding RNAs widely distributed in eukaryotes, have been implicated in the pathogenesis of neurodegenerative disorders and could potentially impact POCD. This review explores the association between miRNAs and POCD and provides an overview of the progress of current research on miRNAs in the pathogenesis, diagnosis, and treatment of POCD.
Insights
Postoperative cognitive dysfunction (POCD) is a common surgical complication. This review examines how microRNAs (miRNAs) may contribute to POCD
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Postoperative cognitive dysfunction (POCD) is a significant clinical challenge following surgical procedures.
- The underlying mechanisms of POCD are not fully understood but may involve neuroinflammation, oxidative stress, and apoptosis.
Approach:
- This review synthesizes current research on the role of microRNAs (miRNAs) in the context of POCD.
- It explores the potential involvement of miRNAs in the pathogenesis, diagnosis, and therapeutic strategies for POCD.
Key Points:
- MicroRNAs (miRNAs), small non-coding RNAs, are increasingly recognized for their roles in various biological processes.
- Emerging evidence suggests miRNAs are implicated in neurodegenerative diseases and may influence POCD development.
- Understanding miRNA involvement could offer new diagnostic and therapeutic avenues for POCD.
Conclusions:
- MicroRNAs represent a promising area of investigation for unraveling the complexities of POCD.
- Further research into miRNA-based biomarkers and therapeutics could significantly impact the management of postoperative cognitive dysfunction.
