遗传学遗传学是一个

背景情况:

急性损伤 (AKI),特别是因缺血-再输血 (I/R) 的急性损伤,在临床上提出了重大挑战,治疗选择有限.
长非编码RNAs (lncRNAs) 越来越被认为是细胞过程和疾病发病的关键调节者,包括损伤.

研究的目的:

调查lncRNA MIR22HG在减轻与缺血性AKI相关的损伤中的作用.
阐明MIR22HG在AKI中的保护作用背后的分子机制.

主要方法:

使用体内 (I/R诱导的AKI小鼠模型) 和体内 (低氧/低氧化治疗的细胞) 实验系统.
采用功能性测试,包括过度表达和功能丧失研究,双露西法酶测试和RNA拉下测试.
分析基因表达和细胞反应,重点关注亡,炎症和功能.

主要成果:

在缺血性AKI模型中,MIR22HG表达显著下调.
过度表达MIR22HG减少了细胞亡和炎症,改善了功能.
MIR22HG通过负调节miR-134-5p来保护MIR22HG免受AKI的影响,后者随后上调调节NFAT5,这是一种减轻压力的转录因子.

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...
