    Background: Gonadotropin-releasing hormone(GnRH) is commonly used in animal reproduction and production, but it was previously reported that GnRH decreases the embryo implantation rate during artificial insemination or embryo transfer in sheep. In addition to the finding that GnRH can target S100A4 to inhibit endometrial cell proliferation, it was also found that endometrial cells were in poor condition and experienced cell death in S100A4 knockout mice, but the mechanism is unclear. Methods: The protein PPP1CA, which interacts with S100A4, was detected by immunoprecipitation-mass spectrometry, and galactosidase staining revealed that overexpression of S100A4 and PPP1CA inhibited cell senescence. Transcriptome sequencing revealed that both S100A4 and PPP1CA targeted and regulated the IL-17 signaling pathway. In vivo experiments confirmed that PPP1CA protein was expressed in the endometria of mice with S100A4 knockout. Results: S100A4 inhibited cell senescence by activating PPP1CA, while PPP1CA overexpression suppressed the activation of the IL-17 signaling pathway. Inhibition of the IL-17 signaling pathway improved the senescence of endometrial cells. Conclusion: Knockdown of S100A4 can target the PPP1CA/IL-17 signaling pathway and promote endometrial cell senescence.
