In-vitro Mutagenesis01:16

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

科学领域:

  • 生殖生物学和分子诊断.
  • 个性化医学的基因组学和转录组学.

背景情况:

  • 子宫内膜受容性对于成功的植入至关重要.
  • 植入窗口 (WOI) 的准确时间对于生育治疗至关重要.
  • 目前用于子宫内膜约会的方法有局限性.

研究的目的:

  • 开发和验证一种新的分析管道,用于使用测序 (TAC-seq) 的目标基因计数来测定子宫内膜约会.
  • 评估这条管道在识别复发性植入失败 (RIF) 的妇女中流离失所的WOI中的实用性.

主要方法:

  • 开发了一种新的TAC-seq管道用于子宫内膜基因表达造型.
  • 在不同周期阶段的子宫内膜活检上进行了差异表达分析.
  • 在健康女性样本上训练并验证了一种定量预测模型.
  • 该模型应用于来自RIF患者的样本.

主要成果:

  • 开发的beREADY选模型在验证中实现了高精度 (98.2%).
  • 在1.8%的孕期妇女中检测到流离失所的WOI.
  • 与受精控制组相比,显著更高的比例 (15.9%) 的RIF女性显示了转移的WOI (p=0.012).

结论:

  • 基于TAC-seq的beREADY模型提供了一种灵敏而准确的方法来预测子宫内膜接受度.
  • 这个工具可以识别流离失所的WOI,为RIF提供潜在的见解.
  • 通过表达式分析,可以实现WOI的个性化定时.
