研究特定miRNA表达水平与儿科的临床特征之间的相关性.
评估精选的miRNAs作为儿童诊断和预后生物标志物的潜力.

主要方法:

文献审查发现了来自成人研究的五个候选miRNA.
定量RT-PCR (RT-qPCR) 在109个儿科血样中测量了miRNA水平.
分析了miRNA表达和临床数据之间的相关性.

主要成果:

在某些miRNAs (miR-142-3p,miR-194-5p,miR-342-5p) 和临床因素 (如性别,发作发作的年龄和家族史) 之间发现了显著的相关性.

MicroRNAs

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...
