Mammalian pregnancy depends on the ability of the uterus to support embryo implantation. Previous studies reveal the Sox17 gene as a downstream target of the Pgr-Gata2-dependent transcription network that directs genomic actions in the uterine endometrium receptive for embryo implantation. Here, we report that ablating Sox17 in the uterine epithelium impairs leukemia inhibitory factor (LIF) and Indian hedgehog homolog (IHH) signaling, leading to failure of embryo implantation. In vivo deletion of the SOX17-binding region 19 kb upstream of the Ihh locus by CRISPR-Cas technology reduces Ihh expression specifically in the uterus and alters proper endometrial epithelial-stromal interactions, thereby impairing pregnancy. This SOX17-binding interval is also bound by GATA2, FOXA2, and PGR. This cluster of transcription factor binding is common in 737 uterine genes and may represent a key regulatory element essential for uterine epithelial gene expression.

SOX17 通过 Ihh 上游的远端增强子调节子宫上皮基质串扰。



哺乳动物怀孕取决于子宫支持胚胎着床的能力。先前的研究表明,Sox17 基因是 Pgr-Gata2 依赖性转录网络的下游靶标,该转录网络指导接受胚胎植入的子宫内膜中的基因组活动。在这里,我们报告消除子宫上皮中的 Sox17 会损害白血病抑制因子 (LIF) 和印度刺猬同源物 (IHH) 信号传导,导致胚胎植入失败。通过 CRISPR-Cas 技术体内删除 Ihh 基因座上游 19 kb 的 SOX17 结合区,会降低 Ihh 在子宫中的表达,并改变适当的子宫内膜上皮-间质相互作用,从而损害妊娠。该 SOX17 结合区间也受 GATA2、FOXA2 和 PGR 的结合。这组转录因子结合在 737 个子宫基因中很常见,可能代表子宫上皮基因表达所必需的关键调控元件。
