Abstract 【Objective】The ten-eleven translocation (TET) protein family play crucial roles in embryo and placental development. The balance of cell death between oviduct and endometrial would affect the development of gametes and early embryos. In this study, the expression patterns and their potential regulatory role of TETs, programmed cell death related genes and blastocyst implantation-related genes in oviduct and uterus of goats in early pregnancy were mainly explored, so as to provide a basis for studying development of gametes and early embryos.【Method】In this study, the uterus and oviduct of Hechuan white goats during non-pregnant 19 days (C19) and pregnant 19 days (P19) were collected, and then the morphology uterine horn was showed by HE staining. Then, the genes, including blastocyst implantation-related genes (Wnt5a, OPN, VEGFA), TET family genes (TET1, TET2, TET3), programmed cell death-related genes (BAX, BCL2, Caspase9, GSDMD, NLRP3 and Caspase1) and inflammation-related genes (NF-kB、TNF-α) were detected by qRT-PCR. Finally, the correlation between TETs and programmed cell death-related genes expression were analyzed.【Result】The results showed that the gland number increased, and its morphology varied in uterine horn in P19 group. Compared with C19 group, OPN gene expression and Bax/BCL2 in uterine horn tissue were significantly increased in P19 group (P<0.01), however, there was no significant difference between Wnt5a and VEGFA. TET family genes were expressed in both oviduct and uterus. The expression of TET1 and TET2 was significantly higher than TET3 in uterine horn (P<0.01). TET2 (P<0.01), NF-kB (P<0.01), Caspase1 (P<0.01), and GSDMD (P<0.05) gene were significantly higher in P19 group of oviduct tissue. Correlation analysis showed that the relationship between TET2 and TET3 (P<0.01), NF-kB (P<0.01) and Caspase9 (P<0.01) in oviduct tissue were positive correlation. The TET3 were negative correlated with VEGFA (P<0.05) and WNT5a (P<0.01). Blastocyst implantation-related genes OPN was positively correlated with Caspase1 (P<0.01), NLRP3 (P<0.05) and GSDMD (P<0.05) in uterine horn. The GSDMD was positively correlated with Bax (P<0.05), Caspase1 (P<0.01) and NLRP3 (P<0.05) in oviduct and uterus horn.【Conclusion】It was indicated that there was correlation between TETs and programmed cell death related genes. So, it was speculated that TET family genes and programmed cell death related genes played a key role in regulating the development of oviduct, zygote, early embryo and uterus. The key genes for embryo implantation of OPN were significantly correlated with pyroptosis related genes, suggesting that proptosis had a certain influence on the attachment of early embryos. These finding provided heretical references for studying the effect of TETs family genes and programmed cell death related genes on oviduct and uterine horn of early pregnancy.
