研究目的: |
本次研究的目的在于证实琥珀酸累积能够调控EPCs的代谢重编程,从而导致EPCs分化成熟障碍,针对琥珀酸累积的靶向治疗可以逆转OSAHS所致血管损伤后的修复功能障碍。因此,本研究拟通过临床试验、体外细胞学试验、体内动物模型实验,分以下几个层面深入探讨琥珀酸累积导致EPCs代谢重编程影响其分化成熟的分子机制: 1.明确OSAHS患者代谢组学特征性变化,初步明确琥珀酸累积与代谢重编程的关系 2.明确OSAHS及健康人群不同组别外周血的EPCs琥珀酸变化情况,明确琥珀酸与EPCs代谢表型改变的关系。 3.明确EPCs代谢表型改变与其分化成熟的关系与机制 4.验证抑制琥珀酸累积可以改变OSAHS小鼠的EPCs代谢表型,促进EPCs分化为成熟的内皮细胞 |

Objectives of Study: |
The purpose of this study is to prove that the accumulation of succinate can regulate the metabolic reprogramming of EPCs, which leads to the disorder of differentiation and maturation of EPCs. Targeted therapy for the accumulation of succinate can reverse the repair dysfunction after vascular injury caused by OSAHS. Therefore, this study intends to use clinical trials, vitro cytology experiments, and vivo animal model experiments to deeply explore the molecular mechanisms of EPCs' metabolic reprogramming, impacting its differentiation and maturity, caused by the accumulation of succinate in the following aspects: 1.Clarify the characteristic changes of metabolomics in patients with OSAHS,and initially clarify the relationship between succinate accumulation and metabolic reprogramming. 2.Clarify the changes of succinic acid in peripheral blood of different groups of OSAHS and healthy people, and clarify the relationship between succinic acid and the metabolic phenotype changes of EPCs. 3.Clarify the relationship and mechanism between the metabolic phenotype changes of EPCs and their differentiation and maturity. 4.Verify that inhibiting the accumulation of succinate can change the metabolic phenotype of EPCs in OSAHS mice and promote the differentiation of EPCs into mature endothelial cells. |
