Understanding endometrial receptivity is key for fertility. Leukemia inhibitory factor and interleukin-11 receptor alpha chain are crucial for embryo implantation, with potential roles in human fertility.

Area of Science:

  • Reproductive biology
  • Molecular genetics
  • Endocrinology

Background:

  • The endometrium presents a hostile environment for embryos, except during a brief fertile window.
  • The molecular mechanisms regulating endometrial receptivity remain largely unknown.
  • Previous research identified key genes like leukemia inhibitory factor (LIF) and interleukin-11 receptor alpha chain (IL-11Rα).

Purpose of the Study:

  • To review current knowledge on genes influencing endometrial receptivity.
  • To investigate the role of LIF and IL-11Rα in embryo implantation.
  • To identify novel genes involved in the implantation process.

Main Methods:

  • Review of literature on endometrial receptivity genes.
  • Analysis of mouse models with null mutations in LIF and IL-11Rα genes.

  • Application of RNA differential display to compare gene expression in mouse uterine implantation and inter-implantation sites.

    • Main Results:

    • Mice lacking LIF or IL-11Rα exhibit infertility due to implantation failure.
    • LIF and IL-11Rα show expression patterns in human endometrium suggesting a role in fertility.
    • RNA differential display identified calcium-binding protein D9K, non-specific suppressor factor beta, and splicing factor SC35 as potentially important genes.

    Conclusions:

    • LIF and IL-11Rα are critical for successful embryo implantation.
    • These genes may play a significant role in human reproductive processes.
    • Further research is needed to explore the therapeutic potential of manipulating these genes for endometrial receptivity.
