Adhere for the newer suggestions). Molecular aberrations that interfere with miRNA processing, export, and/or maturation influence mature miRNA levels and biological activity. Accordingly, most miRNA detection methods concentrate on the analysis of mature miRNA as it most closely correlates with miRNA activity, is additional long-lived, and much more resistant to nuclease degradation than a main miRNA transcript, a pre-miRNA hairpin, or mRNAs. Although the short length of mature miRNA presents positive aspects as a robust bioanalyte, in addition, it presents challenges for distinct and sensitive detection.
