Transcription profiling of mouse uterus reveals Bmp2 IS critical FOR THE murine decidual response

ABSTRACT: The role of bone morphogenetic protein 2 (Bmp2)in regulating the transformation of the uterine stroma during embryo implantation in the mouse was investigated by the conditional ablation of Bmp2 in the uterus using the (PR-cre) mouse. Experiment Overall Design: Bmp2 gene ablation was confirmed by real-time PCR analysis in the PR-cre; Bmp2fl/fl (termed Bmp2d/d) uterus. While littermate controls average 0.9 litter of 6.2 Â± 0.7 pups per month, Bmp2d/d females are completely infertile. Analysis of the infertility indicates that whereas embryo attachment is normal in the Bmp2d/d as in control mice, the uterine stroma is incapable of undergoing the decidual reaction to support further embryonic development. Recombinant human BMP2 can partially rescue the decidual response, suggesting that the observed phenotypes are not due to a developmental consequence of Bmp2 ablation. Microarray analysis demonstrates that ablation of Bmp2 leads to specific gene changes, including disruption of the Wnt signaling pathway, Progesterone receptor (PR) signaling, and the induction of prostaglandin synthase 2 (Ptgs2). Taken together, these data demonstrate that Bmp2 is a critical regulator of gene expression and function in the murine uterus.

Gata2 is a master regulator of endometrial function and progesterone signaling [ChIP-Seq]

Project description:The role of Gata2 in regulating uterine function including fertility, implantation, decidualization and P4 signaling in the mouse was investigated by the conditional ablation of Gata2 in the uterus using the (PR-cre) mouse and ChIP-seq for in vivo GATA2 binding sites in the murine uterus upon acute P4 administration. Gata2 gene ablation was confirmed by real-time PCR analysis in the PR-cre; Gata2fl/fl (termed Gata2d/d) uterus. While littermate controls are fertile, Gata2d/d females are completely infertile. Analysis of the infertility indicates that implantation does not occur, and the uterine stroma is incapable of undergoing the decidual reaction to support further embryonic development. Measure of P4 target genes including PR itself indicate a block in P4 target gene induction and that Gata2 regulates PR expression directly. Microarray analysis demonstrates that ablation of Gata2 leads to specific gene changes, including disruption of the Wnt signaling pathway, Progesterone receptor (PR) signaling, and Ihh signaling pathway. In addition we identified 46,183 GATA2 binding sites in P4 treatment conditions with 7,954 binding sites overlapping that of the PR.Taken together, these data demonstrate that Gata2 is a critical regulator of gene expression and function in the murine uterus.

Gene expression profiling of conditional ablation of Indian hedgehog in the mouse uterus

Project description:Conditional ablation of Indian hedgehog (Ihh) in the murine uterus results in mice that are sterile due to defects in embryo implantation. We performed microarray analysis on these mice at the time point at which the Ihh target genes are induced by the administration of exogenous hormone to mimic day 3.5 of pregnancy. This analysis identified 863 genes altered by the conditional ablation of Ihh. Of these, genes that regulated the cell cycle were overrepresented. In addition, genes involved in epidermal growth factor (EGF) and estrogen (E2) signaling were found to be deregulated upon Ihh ablation. Furthermore, upon conditional ablation of Ihh, 15 month old mice exhibited hallmarks of estrogenized uteri such as cystically dilated glands and hyalinized stroma. Thus, Ihh regulates embryo implantation by impacting the cell cycle, EGF signaling, and E2 signaling. Keywords: two group comparison We conditionally ablated Indian hedgehog in the mouse uterus using the PRcre mouse model (PRcre/+Ihhf/f; Ihhd/d). High density DNA microarray analysis was performed on Day -1 of the artificial decidual response on Ihhf/f and Ihhd/d uteri.

Gene expression profiling of Smad1/5 cKO and Acvr2a cKO mice

Project description:We generated mice with single or double conditional inactivation of SMAD1 and SMAD5 using progesterone receptor (PR) cre (Smad1flox/flox;Smad5flox/flox;Pgr-cre+/-, or “Smad1/5 cKO”). Female mice with single SMAD1 or SMAD5 deletion were subfertile, whereas Smad1/5 cKO were infertile and had no visible implantation sites at 4.5 days post-coitum (dpc), indicating functional redundancy of SMAD1 and SMAD5. Histological and molecular analyses of the Smad1/5 cKO uteri during pregnancy determined that the infertility was the result of impaired uterine receptivity. During the window of implantation, uteri of Smad1/5 cKO mice responded abnormally to estradiol (E2) and to progesterone (P4), retained luminal PR expression, and displayed cytoplasmic FOXO1 mis-localization. Furthermore, uteri of Smad1/5 cKO mice did not respond to an artificial decidual stimulus and the stroma failed to differentiate. To determine the cell surface receptor complex that controls BMP signaling during implantation, we generated mice with conditional deletion of Acvr2a and Acvr2b using Pgr-cre+/-. We determined that Acvr2b cKO females were subfertile, while Acvr2a cKOs were infertile and displayed a range of ovarian and uterine abnormalities, including endometrial and implantation defects that phenocopied those of Smad1/5 cKO mice. Transcriptomic profiling of the Smad1/5 cKO and Acvr2a cKO uterus showed that genes involved in epithelial cell remodeling and microvilli/ciliated cell function were overrepresented in both genotypes. These results demonstrate that BMP signals mediated via ACVR2A and SMAD1/5 control endometrial receptivity and embryo implantation by remodeling the apicobasal polarity of the epithelium during the window of implantation.

Gene expression profiling of constitutive activation of Smoothened in the mouse uterus

Project description:In order to gain a better understanding of Ihh action during embryo implantation, we constitutively activated Smo in the murine uterus using the PRcre mouse model (PRcre/+SmoM2+; SmoM2). Female SmoM2 mice were infertile. They exhibited normal serum progesterone levels and normal ovulation, but ova failed to be fertilized in vivo and the uterus failed to undergo the artificially induced decidual response. SmoM2 mice exhibited uterine hypertrophy. The endometrium had a reduced number of uterine glands and the endometrial stroma lost its normal morphologic characteristics. Microarray analysis of 3 month old SmoM2 uteri demonstrated a chondrocytic signature and confirmed that constitutive activation of SmoM2 increased extracellular matrix production. Thus, constitutive activation of Smo in the mouse uterus alters the extracellular matrix which interferes with early pregnancy. Keywords: two group comparison We constitutively activated Hh signaling in the uterus by the expression of a mutant SmoM2 allele. We crossed these mice to the PRcre mouse model to constitutively activate Smo in the murine uterus (PRcre/+SmoM2+; SmoM2). High density DNA microarray analysis was performed on 3 month old control and SmoM2 uteri.

Gene expression profiling of Activin-like kinase 2 knockout in mice

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 Î² (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/EBPÎ² 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/EBPÎ², 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
