Focus on MicroRNAs as Biomarker in Pediatric Diseases.

ABSTRACT

BACKGROUND: MiRNAs are a class of small non-coding RNAs that are involved in the post-transcriptional regulation of gene expression. MiRNAs are considered a class of epigenetic biomarkers. These biomarkers can investigate disease at different stages diagnosis, therapy or clinical follow-up. OBJECTIVE: The aim of this paper is to highlight the innovative use of miRNAs in several childhood diseases. METHODS: We conducted a literature review to search the usage of miRNAs in pediatric clinical routine or experimental trials. RESULTS: We found a possible key role of miRNAs in different pediatric illnesses (metabolic alterations, coagulation defects, cancer). CONCLUSION: The modest literature production denotes that further investigation is needed to assess and validate the promising role of miRNAs as non-invasive biomarkers in pediatric disorders.
