研究目的:

子宫内膜蜕膜化是胚胎着床和妊娠维持的关键环节。蜕膜化缺陷会导致胚胎着床失败、甚至胚胎发育障碍,从而引起反复种植失败、复发性自然流产、胎盘功能不全等妇产科疾病。目前临床诊断主要依赖病理学和激素水平检测,缺乏针对性分子标志物和干预靶点。本研究从代谢-表观遗传学角度切入,有望揭示复发性流产新的分子机制,为诊疗提供潜在靶点。  

Objectives of Study:

Endometrial decidualization is a crucial step in embryo implantation and pregnancy maintenance. Decidualization defects can lead to failed embryo implantation and even embryo development disorders, thereby causing repeated implantation failures, recurrent spontaneous abortions, placental insufficiency and other gynecological and obstetric diseases. At present, clinical diagnosis mainly relies on pathology and hormone level detection, lacking targeted molecular markers and intervention targets. This study, from the perspective of metabolism-epigenetics, is expected to reveal new molecular mechanisms of recurrent spontaneous abortion and provide potential targets for diagnosis and treatment.
