研究目的: |
本项目的研究目标是通过 ASO 患者动脉组织、粪便标本、体外 VSMC 增生模型和大鼠颈动脉球囊损伤模型中 miR-30b-5p 存在差异表达现象,在此基础上进行生物信息学分析,鉴定出未知的促进 VSMC 发生铁死亡的信号通路,并进行验证,为进一步研究 VSMC 的调控机制指明方向,为在临床上应用铁死亡、铜死亡、菌群变化等途径抑制 VSMC 活性改善 ASO 患者血管管腔狭窄奠定实验基础。 |
||||||||||||||||||||||
|
Objectives of Study: |
The research objective of this project is to investigate the differential expression of miR-30b-5p in arterial tissue, fecal specimens, in vitro VSMC proliferation models, and rat carotid balloon injury models of ASO patients. Based on this, bioinformatics analysis will be conducted to identify unknown signaling pathways that promote iron death in VSMCs and validate them. This will provide direction for further research on the regulatory mechanism of VSMCs and lay an experimental foundation for the clinical application of iron death, copper death, microbial changes, and other pathways to inhibit VSMC activity and improve vascular lumen stenosis in ASO patients. |
