Circular RNAs (circRNAs) show potential as objective biomarkers for diagnosing schizophrenia and depression. These non-coding RNAs are stable, detectable in blood, and may improve early detection and prognosis of these psychiatric disorders.
Area of Science:
- Biochemistry
- Genetics
- Psychiatry
Background:
- Schizophrenia (SZ) and depression (DEP) are major psychiatric disorders linked to suicide risk.
- Current diagnostic methods rely on subjective symptoms, leading to potential misdiagnoses.
- Objective biomarkers are needed for improved early diagnosis and prognosis of SZ and DEP.
Purpose of the Study:
- To review the classification, characteristics, and functions of circular RNAs (circRNAs).
- To highlight the role of circRNAs in the development of SZ and DEP.
- To explore the diagnostic and therapeutic potential of circRNAs in psychiatric disorders.
Main Methods:
- Literature review of circRNA research in SZ and DEP.
- Summary of circRNA classification, characteristics, and biological functions.
- Analysis of experimental studies on circRNA involvement in psychiatric disorders.
Main Results:
- Circular RNAs (circRNAs) are a class of non-coding RNAs involved in post-transcriptional regulation.
- circRNAs are stable, tissue-specific, and detectable in peripheral blood.
- Emerging evidence suggests circRNAs play a role in the pathophysiology of SZ and DEP.
Conclusions:
- circRNAs hold promise as objective biomarkers for SZ and DEP.
- Their detectability in blood offers a minimally invasive approach for diagnosis.
- Further research into circRNAs could lead to novel diagnostic and therapeutic strategies for psychiatric disorders.
