microRNA定量检测方法的研究进展

Current progress in quantitative detection of microRNA

  • 摘要: 随着对microRNA(miRNA)种类、结构和生物学功能研究的不断深入,其在生物发育、代谢调控、疾病发生与治疗干预等方面的重要性受到了广泛关注。由于miRNA稳定性差、表达量低和序列差异小等特征,建立快速简便、灵敏度高、特异性强的miRNA定量检测方法对研究这类生物活性分子的功能至关重要。本文对miRNA的定量检测方法进行分析和比较,为选择合适的miRNA检测方法开展生物学功能研究提供参考和借鉴。

     

    Abstract: With the recent development of investigating biological functions of microRNA(miRNA), the importance of miRNA in the biological processes including developmental biology, metabolic regulation, disease progression and treatment has been well recognized. Due to its the instability, low level of expression and minor difference in sequence, more sophisticated analytical methods for rapid and easy quantitative detection of miRNA with strong specificity and high sensitivity play an important role in the study of the biological functions of miRNA. This review analyzes and compares recent quantitative methods to detect miRNA, with an attempt to provide a foundation for choosing an appropriate method to quantitatively analyze miRNA.
