Prediction models based on miRNA-disease relationship: Diagnostic relevance to multiple diseases including COVID-19.

BACKGROUND
Small, non-coding microRNAs, usually of 20-25 nucleotides, are known to regulate the post-transcriptional gene expression, which has a significant role in human biological processes, including immune-biogenesis, homeostasis and infection control as differential expression of such miRNAs is responsible for fine-tuning the organismic development.


METHODS
A search of bibliographic databases was carried out with a focused question on microRNA-Disease Prediction. A deductive qualitative content analysis approach was further employed to assess the research's overall outcomes, review articles on prediction tools in miRNA-Diseases, and analyse the interventions.


RESULTS
Diagnosis and therapeutics of diseases and miRNA prediction methods hold importance in identifying the regulatory mechanisms. Collections of efficient miRNA prediction methods to identify miRNA-mRNA-disease regulatory relationships have been presented through this review, consolidating the potential of miRNAs as a diagnostic and prognostic biomarker of multiple diseases, including COVID-19.


CONCLUSIONS
The role of miRNA in the aetiology and pathogenesis of wide-range of pathologies, including viral, bacterial to chronic diseases such as cancer, is quite feasible through the modern tools in bioinformatics which has been elaborated focusing upon miRNA-disease prediction methods and their application potential establishing miRNAs as a robust and reliable biomarker in clinico-medical studies.
