Project description:Bone morphogenetic proteins (BMPs) are transforming growth factor β (TGFβ) family members that regulate the post-implantation and mid-gestation stages of pregnancy. In this study we discovered that signaling via activin-like kinase 3 (ALK3/BMPR1A), a BMP type 1 receptor, is necessary for blastocyst attachment. To understand the role of ALK3 in the luminal uterine epithelium, we obtained the gene expression profiles of isolated luminal uterine epithelium from 3.5dpc control and Alk3 cKO mice.

Project description:We used the microarray analysis to determine the differential gene expression profiles in mouse uterine luminal epithelium between preimplantation gestation day 3.5 and postimplantation gestation day 4.5, and investigeate the molecular mechanism of the establishment of uterine receptivity and embryo implantation. Uterine luminal epithelium (LE) is critical for the establishment of uterine receptivity during embryo implantation. Many genes are known to have differential expression in the periimplantation LE but the global profiling of the altered genes in the periimplantation LE is unknown. To fill in this knowledge gap, microarray analysis was performed in gestation day 3.5 (D3.5, preimplantation) and D4.5 (postimplantation) mouse LE from natural pregnancy. There were 382 significantly upregulated and 245 significantly downregulated genes (>2 fold, P<0.05) in the D4.5 LE. There are 6 samples. 3 for gestation day 3.5 uterine luminal epithelium, the other 3 for gestation day 4.5 uterine luminal epithelium

Project description:Implantation of an embryo in the uterus is a multistep process tightly controlled by an intricate regulatory network of interconnected ovarian, uterine, and embryonic factors. Bone morphogenetic protein (BMP) ligands and receptors are expressed in the pregnant uterus, and BMP2 has been shown to be a key regulator of implantation. In this study, we investigated the roles of the BMP type 1 receptor, activin-like kinase 2 (ALK2), during mouse pregnancy by producing uterine-specific Alk2 conditional knockout (cKO) mice. In the absence of ALK2, embryos can invade the uterine epithelium and stroma, but stromal cells cannot undergo uterine decidualization, resulting in sterility. Mechanistically, microarray analysis revealed that CCAAT/enhancer-binding protein β (Cebpb) expression is suppressed during decidualization in Alk2 cKO females. These findings and the similar phenotypes of Cebpb cKO and Alk2 cKO mice lead to the hypothesis that BMPs act upstream of C/EBPβ to regulate decidualization. To test this hypothesis, we knocked down ALK2 in human uterine stromal cells (HESC) and discovered that ablation of ALK2 alters HESC decidualization and suppresses CEBPB mRNA and protein levels. Chromatin immunoprecipitation (ChIP) analysis of decidualizing HESC confirmed that BMP signaling protein, SMAD1, directly regulates expression of CEBPB by binding a distinct regulatory sequence in the CEBPB promoter; C/EBPβ, in turn, regulates the expression of progesterone receptor (PGR). Our work clarifies the conserved mechanisms through which BMPs regulate embryo implantation in rodents and primates and, for the first time, uncovers a linear pathwayof BMP signaling through ALK2 to regulate CEBPB and, subsequently, PGR during decidualization. gene expression profiling of two groups: control mice and Alk2 cKO mice

Project description:Taste papillae are specialized organs, each of which comprises an epithelial wall hosting taste buds and a core of mesenchymal tissue. In the present study, we report that during early taste papilla development in mouse embryos, bone morphogenetic protein (BMP) signaling mediated by type 1 receptor ALK3 in the tongue mesenchyme is required for the epithelial Wnt/β-catenin activity and taste papilla differentiation.

Next, RNA-seq of Muc2-mCherry cells were performed to reveal the regulation of Gli1+ cell on intestinal epithelium.

Project description:Uterine glands are essential for pregnancy in mice and likely humans, because they secrete or transport bioactive substances that regulate uterine receptivity for blastocyst implantation. In mice, the uterus becomes receptive to blastocyst implantation on day 4, but is refractory by day 5. Here, blastocysts could be recovered from progesterone-induced uterine gland (PUGKO) but not wildtype (WT) mice on day 5 post-mating. Anti-adhesive Muc1 protein and microvilli were present on the luminal epithelium of PUGKO but not WT uteri. A number of known uterine receptivity genes and gland-specific genes were altered in the PUGKO uterus. Next, the uterus and uterine luminal fluid (ULF) were obtained from WT and PUGKO mice on day 3, 4 and 5. Transcriptome analysis revealed that 580 genes were decreased in the PUGKO uterus, however ULF secrotome analysis revealed that many proteins and several amino acids were increased in the PUGKO ULF. Of note, many proteins encoded by many gland-specific genes were not identified in the ULF of WT mice. These results support the ideas that uterine glands secrete factors that regulate ULF homeostasis and interact with other cell types in the uterus to influence uterine receptivity and blastocyst implantation for the establishment of pregnancy.

Project description:We recently demonstrated that Msx genes, which encode muscle segment homeobox (Msh) transcription factors, regulate the transition of the luminal epithelium from high to low apicobasal polarity that is critical for implantation. In Msx deficient uteri (Msx1d/d/Msx2d/d), apicobasal polarity remains high and implantation fails to occur. However, information on the underlying molecular mechanism of Msx-dependent regulation of epithelial polarity, and the nature of epithelial-mesenchymal interactions that are characteristic of Msx genes, remain limited. In this study, we analyzed gene expression by RNA-sequencing in the luminal epithelium and stroma isolated by laser capture microdissection (LCM) on day 4 of pseudopregnancy in Msx1f/f/Msx2f/f and Msx1d/d/Msx2d/d uteri. We found upregulation of extracellular matrix components in the stroma and downregulation of immunity-related genes in both the luminal epithelium and stroma isolated from Msx1d/d/Msx2d/d mice. In addition, tight junction protein Claudin 1 and small proline-rich protein (Sprr2) were substantially upregulated in Msx1d/d/Msx2d/d epithelia. mRNA profiles of luminal epithelium and stroma from a wildtype Msx1f/f/Msx2f/f and a uterine-specific knockout Msx1d/d/Msx2d/d mouse were asessed by RNA-sequencing with the Illumina HiSeq 1500 system
