Hypothesis
The study aims to identify IL11 regulated plasma membrane proteins in human endometrial epithelial cells in vitro.
Conclusion
The study identifies two proteins, ANXA2 and FLOT1, that are upregulated by IL11 and may play a role in endometrial receptivity and embryo implantation.
Supporting Evidence
- IL11 treatment resulted in a 2-fold increase of ANXA2 in hEEC membrane fractions.
- FLOT1 showed a 1.8-fold increase in hEEC membrane fractions after IL11 treatment.
- Both ANXA2 and FLOT1 were validated by Western blot and immunocytochemistry.
Takeaway
This study found that a protein called ANXA2 and another called FLOT1 are increased by a substance called IL11, which might help embryos stick to the uterus better.
Methodology
The study used 2D-differential in-gel electrophoresis (DIGE) and LCMS/MS mass spectrometry to analyze protein expression in endometrial epithelial cells.
Limitations
The study did not assess the effects of IL11 on total protein levels in primary hEEC, which may limit the understanding of its overall impact.
Participant Demographics
Women aged 32-40 years with normal menstrual cycles.
Statistical Information
