概括
复发性植入失败 (RIF) 患者经常会出现植入窗口 (WOI) 的移位. 转录组分析确定了与WOI移位相关的基因表达模式,通过个性化胚胎移植提高了怀孕率.
科学领域:
- 生殖医学 生殖医学
- 基因组学就是基因组学.
- 分子生物学分子生物学
背景情况:
- 复发性植入失败 (RIF) 是一种复杂的疾病,通常与异常的子宫内膜受体和移位植入窗口 (WOI) 有关.
- 在RIF患者中驱动WOI移位的精确分子机制在很大程度上仍然未被描述.
- 了解这些机制对于开发有针对性的诊断和治疗策略至关重要.
研究的目的:
- 调查RIF患者的子宫内膜组织的转录密码签名,其中包括正常和位移的WOI.
- 确定负责子宫内膜受体异常和WOI位移的特定基因和途径.
- 为了将基因表达模式与个性化胚胎移植后的临床结果相关联.
主要方法:
- 招募了40名接受个性化胚胎移植 (pET) 的RIF患者,以子宫内膜受体诊断 (ERD) 模型为指导.
- 在子宫内膜样本上进行了转录组分析,以确定与WOI移位相关的差异表达基因 (DEG).
- 将激素替代疗法 (HRT) 和自然循环之间的基因表达特征进行比较,以确定与WOI相关的基因模式.
主要成果:
- 子宫内膜接受性诊断 (ERD) 显示,67.5%的RIF患者在HRT周期中的常规WOI (P+5) 期间有非接受性子宫内膜.
- 在RIF患者中,ERD引导的pET显著提高了临床怀孕率,达到65%.
- 转录组分析确定了10个参与免疫调节,运输和组织再生的DEG,这些DEG可以准确地分类不同的WOI状态 (高级,正常,延迟).
- 在WOI期间,在自然和HRT周期中观察到与ER相关的基因的类似基因表达模式.
结论:
- 与ER相关基因的异常表达与RIF患者的WOI位移有关.
- 基于转录组的WOI预测和ERD模型对于评估子宫内膜受容性是有效的.
- 基于ERD结果的个性化胚胎移植时间显著提高了RIF患者的怀孕结果.

Ovarian Cycle
1.2K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Hormonal Regulation of the Menstrual Cycle
389
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
