Adhere to the newer guidelines). Molecular aberrations that interfere with miRNA processing, export, and/or maturation affect mature miRNA levels and biological activity. Accordingly, most miRNA detection strategies focus around the analysis of mature miRNA since it most closely correlates with miRNA activity, is far more long-lived, and much more resistant to nuclease degradation than a principal miRNA transcript, a pre-miRNA hairpin, or mRNAs. While the brief length of mature miRNA presents positive aspects as a robust bioanalyte, additionally, it presents challenges for distinct and sensitive detection.
