1 SUMMARY ANSWER: Podocalyxin (PCX), a transmembrane protein, was identified as a key negative regulator of endometrial epithelial receptivity; specific downregulation of PCX in the luminal epithelium in the mid-secretory phase, likely mediated by progesterone, may act as a critical step in converting endometrial surface from a non-receptive to an implantation-permitting state. Progesterone podocalyxin like Homo sapiens

Progesterone podocalyxin like Homo sapiens
4 To investigate whether PCX is regulated by progesterone, the master driver of endometrial differentiation, primary HEECs were treated in culture with estradiol and progesterone and analyzed by RT-PCR (n = 5) and western blot (n = 4). Progesterone podocalyxin like Homo sapiens
5 Progesterone was confirmed to be able to suppress PCX in primary HEECs, suggesting this hormone likely mediates the downregulation of luminal PCX in vivo for receptivity. Progesterone podocalyxin like Homo sapiens
6 Progesterone was confirmed to be able to suppress PCX in primary HEECs, suggesting this hormone likely mediates the downregulation of luminal PCX in vivo for receptivity. Progesterone podocalyxin like Homo sapiens
7 Future study would need to investigate how progesterone differentially regulates PCX in endometrial epithelial subtypes. Progesterone podocalyxin like Homo sapiens
8 The study also discovered PCX as progesterone target in HEECs, identifying a potentially useful functional biomarker to monitor progesterone action, such as in the optimization of progesterone type/dose/route of administration for luteal support. Progesterone podocalyxin like Homo sapiens
