microRNAs in Human Diseases
MicroRNAs are short, non-coding oligonucleotides that regulate many genes by suppressing protein translation or through transcript degradation. Nearly every biological process thus far investigated is regulated, in part, by microRNAs. Consequently, aberrant microRNA activity is associated with many diseases and pathological events. Mature microRNAs are approximately 22 nucleotides in length and anneal to complementary sites in the 3’ untranslated region (UTR) of target transcripts as part of an RNA-induced silencing complex (RISC). There are currently more than 2000 known microRNAs in the human genome, and each microRNA may regulate dozens to hundreds of target transcripts. The 3’ UTR in a single messenger RNA may contain binding sites for numerous microRNAs, and a transcript can be concurrently repressed by multiple microRNA species. Therefore, microRNAs are part of a highly complex gene regulatory network. To improve our detection and treatment of diseases it is important to untangle this network and understand how microRNAs are involved in disease processes. |
microRNAs as Biomarkers in Pediatric Asthma
Our study demonstrated the potential of using microRNAs obtained from non-invasive nasal swabs as biomarkers of asthma severity. We found that microRNA miR-582-5p was significantly increased in the nasal epithelium of pediatric patients having severe asthma.
