概括

这项研究表明,特定的microRNAs (miRNAs) 与尿酸结石 (UAC) 有关. 像143-3p,4770,4750-3p,301b-5p和9-5p这样表达不足的miRNAs可能会导致UAC的发展.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
遗传学是一个遗传学.
分子生物学分子生物学

背景情况:

尿酸结石 (UAC) 在全球范围内约占结石的10%.
结石病的病因是多因素的,受遗传倾向和环境因素的影响.
特定的基因 (ZNF365,SLC2A9,SLC22A12) 和微RNA (miRNA) 都与UAC的发展有关.

研究的目的:

在尿液化症患者中,描述与SLC2A9,SLC22A12和ZNF365基因相关的miRNAs的表达特征.
研究miRNA表达与尿酸结石形成的临床特征之间的相关性.

主要方法:

研究包括22名纯尿结石患者和8名对照患者.
使用miRVana套件提取了总RNA.
量化聚合酶链反应 (qPCR) 用于分析miRNA表达水平.

主要成果:

患有石病的患者表现出显著的高尿血和更酸的尿液.
在患有结石的患者中,观察到尿中较低的酸盐分泌量.
在UAC患者中观察到miRNAs143-3p,4770,4750-3p,301b-5p和9-5p的统计学上显著的表达不足.

结论:

微RNA143-3p,4770,4750-3p,301b-5p和9-5p可能与尿液化发展有关.
毫米RNAs 4770和4750-3p的表达不足与多重石头发生有关.
过度表达miR-4750-3p与较大的石头 (>2厘米) 的形成有关.

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 the pre-miRNA...
