遗传学是一个遗传学.
细胞生物学细胞生物学

背景情况:

重复植入失败 (RIF) 在辅助生殖技术中构成了重大挑战.
了解RIF背后的分子机制对于开发有效的治疗方法至关重要.

研究的目的:

为了研究RPA2在经历RIF的患者子宫内膜中的表达模式和功能作用.
阐明RPA2影响子宫内膜脱细胞化的机制.

主要方法:

从GEO数据库中对基因表达进行分析,以确定RIF患者中差异表达的基因.
定量实时PCR (RT-qPCR),免疫组织化学和西部抹杀,以评估子宫内膜组织中的RPA2表达.
在实验室中使用具有RPA2过度表达的人类子宫内膜层细胞 (HESC) 进行决定化试验.

主要成果:

在RIF患者中部分泌性子宫内膜中,RPA2显著上调.
在增殖阶段,RPA2表达率较高,而在HESC决定化过程中则下调.
过度表达RPA2抑制了决定化标记物,包括益乳素 (PRL) 和类似胰岛素的生长因子结合蛋白1 (IGFBP1).

结论:

在RIF患者中,RPA2的异常上调减轻了子宫内膜决定.

Proliferative Phase

Proliferative Phase

The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
