概括

微RNAs (miRNAs) 通过调节血管生成和炎症,显著影响慢性静脉腿 (CVLU) 愈合. 本次审查强调了促进或阻碍愈合过程的特定miRNA,强调了需要进一步研究的必要性.

科学领域:

生物医学科学生物医学科学
分子生物学分子生物学
伤口治愈研究研究伤口治愈研究

背景情况:

慢性静脉腿 (CVLUs) 是一种常见的下肢伤口形式,病理生理学不完全理解.
微RNAs (miRNAs) 参与炎症过程,但它们在CVLU愈合中的特定作用需要进一步研究.

研究的目的:

进行范围审查,检查微RNAs (miRNAs) 在慢性静脉腿 (CVLUs) 治愈中的作用.
在CVLU治愈的背景下,识别与血管生成,炎症和细胞增殖相关的特定miRNA.

主要方法:

在2023年12月,在主要数据库 (MEDLINE/PubMed,Embase,Scopus,CINAHL) 进行了全面的文献搜索.
包括在2013年至2023年期间发表的研究,重点关注CVLU治疗中的miRNAs.
提取的miRNA数据来源于各种生物标本,包括血清,皮肤活检和介质细胞.

主要成果:

发现特定的miRNAs可以差异调节血管生成;例如,miR-221/222的过度表达阻碍了它,而miR-296/126则促进了它.
某些miRNAs,如miR-34a/c,加剧了炎症并抑制了角质细胞的增殖,阻碍了愈合.
相反,像miR-205/218-5p这样的miRNAs的下调促进了细胞增殖和增强伤口愈合.

结论:

微RNA是慢性伤口愈合的关键过程的关键调节者,包括血管新生,炎症和细胞迁移.
目前对CVLU中miRNA的研究是有限的,缺乏标准化的方法.
进一步的研究对于充分了解CVLU病理生理学中的miRNA机制以及开发有针对性的治疗策略至关重要.

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 the pre-miRNA...

Phases of Wound Repair

Phases of Wound Repair

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...
