背景情况:
- 线粒体功能障碍和DNA (mtDNA) 释放与高增殖性疾病有关.
- 缺氧与通过线粒体功能障碍与腺菌症 (AM) 病原发生有关.
- 在AM中cGAS-STING通路和mtDNA的作用尚未完全理解.
研究的目的:
- 调查mtDNA分泌,cGAS-STING通路激活和AM中异常增殖之间的联系.
- 阐明缺氧在AM中激活cGAS-STING通路中的作用.
主要方法:
- 在AM组织中分析cGAS,STING,TBK1,IRF3蛋白水平和炎症性细胞因子.
- 在缺氧条件下评估子宫内膜层细胞 (ESC) 增殖,迁移和mtDNA释放.
- 研究mtDNA删除和STING基因淘汰对cGAS-STING通路和细胞行为的影响.
主要成果:
- 在AM组织中观察到高水平的cGAS,STING,TBK1,IRF3,IL-6和IFN-α.
