Adhere for the newer guidelines). Molecular aberrations that interfere with miRNA processing, export, and/or maturation impact mature miRNA levels and biological activity. Accordingly, most miRNA detection approaches concentrate on the evaluation of mature miRNA since it most closely correlates with miRNA activity, is much more long-lived, and much more resistant to nuclease degradation than a principal miRNA transcript, a pre-miRNA hairpin, or mRNAs. Whilst the quick length of mature miRNA presents advantages as a robust bioanalyte, in addition, it presents challenges for precise and sensitive detection.

Molecular aberrations that interfere with miRNA processing, export, and/or maturation affect mature miRNA levels and biological activity. Accordingly, most miRNA detection approaches concentrate on the evaluation 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 main miRNA transcript, a pre-miRNA hairpin, or mRNAs. Even though the brief length of mature miRNA presents advantages as a robust bioanalyte, it also presents challenges for certain and sensitive detection.
