miRNA Analysis and Real-Time PCR (qPCR) Information
MicroRNAs are single-stranded, 19- to 25-nucleotide RNAs that regulate gene expression post-transcriptionally by binding to the 3’ untranslated regions (UTRs) of target mRNAs, inhibiting their translation. The high relative stability of miRNA in biofluids (e.g., plasma, serum, urine, saliva, etc.) and the ability of miRNA expression profiles to accurately classify discrete tissue types and disease states have positioned miRNA quantification as a promising new tool for a wide range of biomarker discoveries. MicroRNAs are gaining popularity in emerging applications such as early detection of cancer, cardiovascular diseases, and simultaneous detection of miRNA and mRNA from the same samples for pathway analysis, etc.
