MicroRNAs (miRNAs) show promise as biomarkers for diagnosing diseases like cancer. This review explores their diagnostic potential and the challenges in clinical application.
Area of Science:
- Molecular Biology
- Biochemistry
- Genetics
Background:
- MicroRNAs (miRNAs) are small non-coding RNAs regulating biological processes.
- Dysregulated miRNAs are implicated in diseases, notably cancer.
- Circulating and exosomal miRNAs are emerging as potential disease biomarkers.
Purpose of the Study:
- To review the role of miRNAs as biomarkers for cancer and other diseases.
- To summarize clinical evidence supporting miRNA diagnostics.
- To discuss analytical challenges and future perspectives for miRNA biomarker use.
Main Methods:
- Literature review of studies on miRNA biomarkers.
- Analysis of clinical evidence for miRNA diagnostic applications.
- Evaluation of analytical and validation challenges.
Main Results:
- miRNAs are associated with various diseases including cancer, viral infections, neurological, cardiovascular disorders, and diabetes.
- Clinical evidence supports the diagnostic utility of miRNAs.
- Significant analytical challenges exist in validating miRNA signatures for clinical use.
Conclusions:
- miRNAs hold significant potential as biomarkers for diverse diseases.
- Further validation and overcoming analytical hurdles are crucial for clinical implementation.
