Project description:To understand the role of GRB2 in the uterus, we generated mice with conditional ablation of Grb2 in the PGR positive cells (Pgrcre/+Grb2f/f; Grb2d/d). Grb2d/d mice are infertile due to implantation failure. Although ovarian functions are normal, Grb2d/d mice had non-receptive endometrium due to dysregulation of progesterone and estrogen signaling. Our transcriptomic analysis identified deficiency of progesterone and FOXA2 signaling.

Project description:Endometriosis is a disease in which tissue that normally grows inside the uterus grows outside the uterus and causes chronic pelvic pain and infertility. However, the exact mechanisms of the pathogenesis of endometriosis-associated infertility are unknown. Epigenetic dysregulation has recently been implicated in infertility. Here, we report a reduction of histone deacetylase 3 (HDAC3) protein amounts in eutopic endometrium of infertile women with endometriosis compared to a control group. To investigate the effect of HDAC3 loss in the uterus, we generated mice with conditional ablation of Hdac3 in progesterone receptor (PGR)-positive cells (Pgrcre/+Hdac3f/f ; Hdac3d/d ). Loss of Hdac3 in the uterus of mice results in infertility due to implantation failure and decidualization defect. Expression microarray and ChIP-seq analyses identified COL1A1 and COL1A2 as direct targets of HDAC3 in both mice and humans. Reduction of HDAC3 abrogated decidualization in a primary culture of human endometrial stromal cells (hESCs) similar to that observed in infertile patients with endometriosis. Whereas attenuation of HDAC3 resulted in p300 recruitment to Col1a1 and Col1a2 genes in the uterus of mice as well as hESCs, inhibition of p300 permitted hESCs to undergo decidualization. Collectively, we found attenuation of HDAC3 and overexpression of collagen type I in the eutopic endometrium of infertile patients with endometriosis. HDAC3 loss caused a defect of decidualization through the aberrant transcriptional activation of Col1a1 and Col1a2 genes in mice and COL1A1 and COL1A2 genes in humans. Our results suggest that HDAC3 is critical for endometrial receptivity and decidualization.

Project description:The product of the Bmal1 locus is an essential component of the circadian clock that plays important roles in various aspects of reproductive biology, and its disruption results in infertility. In an effort to identify the identity of the tissue specific clock that is responsible for this infertility, we used the steroidogenic factor-1 (Sf1) promoter to drive Cre-mediated recombination and genetically delete Bmal1 within cells of the reproductive axis. We show that Bmal1 within the reproductive axis of females is essential for normal fertility through its role in maintaining implantation, but is not required for normal estrous cycling. At the root of this biology appears to be a defect in the regulation of ovarian steroidogenic acute regulator (StAR) and its role in maintaining progesterone synthesis. This conclusion is based upon three observations. First, that deletion of Bmal1 within the reproductive axis leads to lower levels of StAR mRNA, and lower progesterone levels. Second, that progesterone supplementation of these conditional mutants rescues implantation. Third, transplantation of wild type ovaries into Bmal1 reproductive axis mutants results in 100% fertility. Our study suggests that ovarian Bmal1 is an essential peripheral clock governing implantation and fertility in female mice. Ten week old female Bmal1fxfx mice positive or negative for Cre-recombinase driven by the sf-1 promoter, housed in 12 hour light:12 dark, ad lib feeding and drinking conditions were sacrificed at ZT12 on 3.5dpc (3.5 days post copulation). For each array analysis, a pool of 3 RNA samples from 3 individual Bmal1fx/fxCresf-1 ovaries labeled with cy3 were co-hybridized with a pool of 3 RNA samples from Bmal1fx/fx ovaries labeled with cy5, according to Agilent protocols.

Project description:The product of the Bmal1 locus is an essential component of the circadian clock that plays important roles in various aspects of reproductive biology,and when disrupted results in infertility. In an effort to establish the identity of the tissue specific clock that is responsible for this infertility, we used the steroidogenic factor-1 (Sf1) promoter to drive Cre-mediated recombination and genetically delete Bmal1 within cells of the reproductive axis. We show that Bmal1 within the reproductive axis of females is essential for normal fertility through its role in maintaining implantation, but is not required for normal estrous cycling. At the root of this biology appears to be a defect in the ovaries, including regulation of ovarian lipid biosynthetic or metabolic processes and their roles in maintaining progesterone synthesis. This conclusion is based upon three observations. First, that deletion of Bmal1 within the reproductive axis reducesleads to affected transcripts in steroidogenic pathways for the LH receptor , and lowers progesterone levels. Second, that progesterone supplementation of these conditional mutants rescues implantation. Third, transplantation of wild type ovaries into Bmal1 reproductive axis mutants rescues fertility. Our study demonstrates the significance of ovarian Bmal1 as an overriding influence in experimental models of infertility. A time series was performed in time-mated C57Bl/6J mice to identiy oscillating transcripts. During the peak and trough of the majority of transcripts (ZT0 and ZT12) samples from Bmal1fx/fx Sf1Cre mice and control litermates as well and global Bmal1 nulls were also analyzed. The tissue types (ovary, pituitary) are not comparable.
