MicroRNAs (miRNAs)是一种小的非编码rna,通过抑制靶mRNA的翻译,在转录后影响广泛的细胞过程,如宿主对病毒感染的反应、先天免疫、细胞周期进程、迁移和凋亡。由于microrna数量的增加及其功能作用的鉴定,许多不同样品类型的miRNA谱分析变得更加广泛,特别是与疾病特征相关。在这里,我们讨论了目前可用的miRNA表达谱方法的一些优点和潜在的缺陷。讨论的一些主题包括异构体rna,不同分析平台的比较,标准化策略以及有关样品制备和实验分析的问题。
MicroRNAs (miRNAs) are small, noncoding RNAs that post-transcriptionally influence a wide range of cellular processes such as the host response to viral infection, innate immunity, cell cycle progression, migration and apoptosis through the inhibition of target mRNA translation. Due to the growing number of microRNAs and identification of their functional roles, miRNA profiling of many different sample types has become more expansive, especially with relevance to disease signatures. Here, we address some of the advantages and potential pitfalls of the currently available methods for miRNA expression profiling. Some of the topics discussed include isomiRNAs, comparison of different profiling platforms, normalization strategies and issues with regard to sample preparation and experimental analyses.
