Project description:To uncover genes regulated by mTORC1 and estradiol in uterine Tsc2-null LAM like cells, we performed RNAseq on uteri from 12-week old wild-type (WT) and uterine-specific Tsc2-null (KO) mice that were either untreated (intact), oopherectomized (ovx) or oopherectomized + treated with 17β-estradiol pellets (E2) for 8 weeks. We identified genes that were both estradiol- and TSC2-mediated. Uterine mRNA profiles of 12 week old wild type (WT) and uterine-specific Tsc2-null (KO) mice in the presence or absence of estradiol were generated using Illumina HiSeq2500

Project description:Aberrant activation of the mammalian target of rapamycin (mTOR) complex 1 (mTORC1) is a common molecular event in a large variety of pathological settings, including genetic tumor syndromes, cancer, and obesity. However, the cell intrinsic consequences of mTORC1 activation remain poorly defined. Here, we identify global trancriptional changes in TSC1 and TSC2 null MEFs, which exhibit constitutive activation of mTORC1, compared to wild-type littermate control lines. A rapamycin time course is included to determine those changes that are dependent on mTORC1 signaling, revealing mTORC1 induced and repressed transcripts. In order to identify mTORC1-dependent transcriptional changes, we compared wild-type MEFs to both Tsc1-/- and Tsc2-/- MEFs following serum starvation, where mTORC1 signaling is off in wild-type cells and fully active in TSC-deficient cells. All cell lines were serum-starved for 24 h, and the Tsc1-/- and Tsc2-/- cells were treated with a time course of rapamycin prior to the isolation of mRNA for microarray analysis. Immortalized wild-type (Tsc2+/+ p53-/-), Tsc1-/- (p53+/+, 3T3-immortalized), and Tsc2-/- (p53-/-, derived from a littermate of the wild-type cell line) MEFs are the three cell lines used in this study and were derived in the laboratory of David J. Kwiatkowski (Brigham and Women's Hospital, Harvard Medical School, Boston, MA). Wild-type and null MEFs were grown to 70% confluence in 10 cm plates and were serum starved for 24 h in the presence of vehicle (DMSO) for 24 h or rapamycin (20 nM) for 2, 6, 12, or 24 h. All vehicle-treated samples (0 h time points) were plated in triplicate and all rapamycin time course samples were plated in duplicate. For each replicate, expression analysis was performed by hybridization to an Affymetrix Mouse 430_2 oligonucleotide microarray chip.

Project description:Comparison of the gene expression profiles of pre-implantation embryos at day 3.5 post coitum from normal pregnant mice (control); embryos from mice treated with ICI (specific estrogen receptor inhibitor); and embryos in the oviduct that were blocked from entering the uterus by ligation. Results provide insight into the function of estrogen regulated genes and uterine factors involved in the early implantation process. RNA were extracted from 3 groups of 100-120 embryos (a) embryos at d3.5 from uterus of normal pregnant mice; (b) embryos at d3.5 from uterus of ICI treated mice; and (c) embryos at d3.5 from the ligated oviduct.

Project description:Mammalian target of rapamycin (mTOR) complex 1 (mTORC1) is a critical regulator of cell growth by integrating multiple signals (nutrients, growth factors, energy and stress) and is frequently deregulated in many types of cancer. We used a robust experimental paradigm involving the combination of two interventions, one genetic and one pharmacologic to identify genes regulated transcriptionally by mTORC1. In Tsc2+/+, but not Tsc2-/- immortalized mouse embryo fibroblasts (MEFs), serum deprivation downregulates mTORC1 activity. In Tsc2-/- cells, abnormal mTORC1 activity can be downregulated by treatment with rapamycin (sirolimus). By contrast, rapamycin has little effect on mTORC1 in Tsc2+/+ cells in which mTORC1 is already inhibited by low serum. Thus, under serum deprived conditions, mTORC1 activity is low in Tsc2+/+ cells (untreated or rapamycin treated), high in Tsc2-/- cells, but lowered by rapamycin; a pattern referred to as a M-^Slow/low/high/lowM-^T or M-^SLLHLM-^T, which allowed the identification of genes regulated by mTORC1 by performing the appropriate comparisons

Project description:Postnatal development of the uterus involves specification of undifferentiated epithelium into uterine-type epithelium. That specification is regulated by stromal-epithelial interactions as well as intrinsic cell-specific transcription factors and gene regulatory networks. This study utilized mouse genetic models of Esr1 deletion, endometrial epithelial organoids (EEO), and organoid-stromal co-cultures to decipher the role of Esr1 in uterine epithelial development. Organoids derived from wild-type (WT) mice developed a normal single layer of columnar epithelium. In contrast, EEO from Esr1 null mice developed a multilayered stratified squamous type of epithelium with basal cells. Co-culturing Esr1 null epithelium with WT uterine stromal fibroblasts inhibited basal cell development. Of note, estrogen treatment of EEO-stromal co-cultures and Esr1 conditional knockout mice increased basal epithelial cell markers. Collectively, these findings suggest that Esr1 regulates uterine epithelium lineage plasticity and homeostasis and loss of ESR1 promotes altered luminal-to-basal differentiation driven by ESR1-mediated paracrine factors from the stroma.

Project description:Our previous study revealed that the basic helix-loop-helix transcription factor Hand2 is a downstream target of progesterone signaling in mouse uterine stroma at the time of implantation. Further, conditional deletion of Hand2 in mouse uterus leads to implantation failure due to impaired uterine epithelial receptivity. To identify the downstream targets of Hand2 in the uterus, we performed gene expression profling of uterine stromal cells isolated from Hand2-null mice and the corresponding controls on day4 of pregnancy (the time of implantation). The microarray results revealed elevated expression of mRNAs corresponding to several members of the fibroblast growth factor family in uterine stroma of Hand2-ablated mice. These factors act as paracrine mediators of mitogenic effects of estrogen on the epithleium. Thus, Hand2 is a critical regulator of the uteirne stromal-epithelial communication that directs proper steroid regulation conducive for establshment of pregnancy. We performed conditional ablation of Hand2 in the mouse uterus using the PRcre mouse model. As Hand2 expression is restricted to stromal comaprtment, we isolated uterine stromal cells from day4 pregnant mice (n=5 for each genotype), purified total RNA from these cells, pooled these samples and then hybridized to high density affymetrix microarrays. Control vs. KO.
