研究目的: |
慢性阻塞性肺疾病(chronic obstructive pulmonary diseases,COPD)的重要发病机制之一是氧化还原失衡,过氧化物酶体增殖体激活受体γ(PPARγ)对氧化应激和炎症具有保护作用,在COPD中下调,其机制不明。STAU1是一个双链RNA结合蛋白,在COPD中上调,其介导的SMD途径能够影响mRNA的稳定性及翻译。本课题组前期发现PPARγ存在双链RNA结构并能与STAU1特异性结合。因此推测STAU1介导的SMD途径可能通过调节PPARγ促进COPD的氧化应激反应。本项目拟通过RIP、siRNA实验等方法,详细探索COPD中STAU1调节PPARγ mRNA稳定性的具体机制,并通过在体实验,考察STAU1对COPD氧化应激反应的作用。上述研究将阐明COPD患者中PPARγ降解的机制,并揭示STAU1及其介导的SMD途径在COPD相关氧化应激中的作用,为防治COPD提供新靶点和理论依据。 |

Objectives of Study: |
One of the important pathogenesis of chronic obstructive pulmonary diseases (COPD) is REDOX imbalance. Peroxisome proliferator-activated receptor γ(PPARγ) has a protective effect on oxidative stress and inflammation, and is down-regulated in COPD. The mechanism is unclear. STAU1 is a double-stranded RNA-binding protein that is upregulated in COPD, and its mediated SMD pathway can affect mRNA stability and translation. Our research group previously found that PPARγ has a double-stranded RNA structure and can specifically bind to STAU1. Therefore, it is speculated that STAU1-mediated SMD pathway may promote oxidative stress response in COPD by regulating PPARγ. This project intends to explore in detail the specific mechanism by which STAU1 regulates the stability of PPARγ mRNA in COPD through RIP and siRNA experiments, and investigate the effect of STAU1 on oxidative stress in COPD through in vivo experiments. These studies will elucidate the mechanism of PPARγ degradation in COPD patients, and reveal the role of STAU1 and its mediated SMD pathway in COPD related oxidative stress, providing new targets and theoretical basis for the prevention and treatment of COPD. |
