为了研究循环中的microRNAs (miRNAs) 作为慢性疹 (CU) 患者的潜在生物标志物.
为了比较CU患者和健康个体之间的miRNA表达特征.

主要方法:

对miRNAs的基因表达分析对7名CU患者和7名健康对照进行.
TaqMan openArray人类高级miRNA面板和ExpressionSuite软件用于量化.
统计学意义被设定为p<0.05.05.

主要成果:

与对照组相比,CU患者的五种特定miRNAs (miR-451a,miR-9-5p,miR-150-5p,miR-296-5p,miR-182-5p) 在CU患者中显著上调.
miR-451a失调被认为是过敏疾病中潜在的早期生物标志物.
功能分析将这些miRNA与皮肤疾病和炎症途径联系起来.

结论:

循环中的miRNAs,特别是高调的miRNAs,可能在慢性疹 (CU) 的发病和炎症中发挥重要作用.
这些miRNAs代表了未来有希望的生物标志物和CU的潜在治疗点.
进一步研究miRNA在CU中的作用是有必要的.

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...
