Abstract:
The most prevalent mental illness worldwide and the main contributor to suicide and disability is major depressive disorder. Major depressive disorder is now diagnosed and treated based on the patient's statement of symptoms, mental status tests, and clinical behavioral observations. The central element of this review is the increased need for an accurate diagnostic method. In this context, the present research aims to investigate the potential role of two non-coding RNA species (microRNA and long non-coding RNA) in peripheral blood samples and brain tissue biopsy from patients with major depressive disorder. This study reviewed the literature on microRNA and long non-coding RNA expression in blood and brain tissue samples in human and animal depression models by retrieving relevant papers using the PubMed database. The results reveal significant variations in microRNA and long non-coding RNA levels in depressed patients, making it a crucial diagnostic tool that predicts treatment outcomes. It can help track severe cases and adjust therapy dosages based on treatment responses. In conclusion, microRNAs and long non-coding RNAs are pertinent biomarkers that can be added to the diagnostic test panel for major depressive disorder. Both microRNAs and non-coding RNAs can also be used as a tool to track patient progress during therapy and to assist the attending physician in tracking the molecular development of the disease.
Insights
Major depressive disorder (MDD) diagnosis may be improved using microRNA and long non-coding RNA biomarkers. These non-coding RNAs in blood and tissue show significant variations in MDD patients, aiding diagnosis and treatment monitoring.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Major depressive disorder (MDD) is a leading cause of global disability and suicide.
- Current MDD diagnosis relies on subjective symptom reporting and clinical observation.
- There is a critical need for objective and accurate diagnostic methods for MDD.
Purpose of the Study:
- To investigate the potential of microRNA (miRNA) and long non-coding RNA (lncRNA) as biomarkers for MDD.
- To explore the diagnostic and prognostic value of miRNA and lncRNA expression in peripheral blood and brain tissue.
Main Methods:
- A comprehensive literature review was conducted using the PubMed database.
- Studies examining miRNA and lncRNA expression in human and animal models of depression were included.
- Expression levels in blood and brain tissue samples from MDD patients were analyzed.
Main Results:
- Significant alterations in miRNA and lncRNA levels were observed in patients with MDD.
- These non-coding RNAs demonstrate potential as diagnostic tools for MDD.
- Expression patterns correlate with treatment outcomes and can guide therapy adjustments.
Conclusions:
- MicroRNAs and long non-coding RNAs are promising biomarkers for MDD diagnosis.
- These molecules can serve as tools for monitoring patient progress and disease progression during treatment.
- Integrating miRNA and lncRNA analysis into diagnostic panels may enhance MDD management.
