Gene expression profiling of ovaries collected from mice treated with or without Ulipristal

ABSTRACT: Ulipristal acetate (UPA), also referred to as VA/CDB-2914, is a new and promising emergency contraceptive. It is a selective progesterone receptor modulator (SPRM) that has been approved in Europe and the USA for emergency contraception. To experimentally induce ovulation, the immature CD-1 mice (24–28 d old) were injected ip with 5 IU of PMSG and 48 h later by 5 IU of hCG. Two hour after hCG treatment, mice were administered with UPA/CDB or vehicle/OIL. Ovaries were collected at 11 h and total RNA was analyzed using Affymetrix mouse arrays

Ulipristal acetate (UPA), a progesterone receptor (PR) modulator, is used as an emergency contraceptive in women. Here, using a mouse model, we investigated the mechanism of action of UPA as an ovulation blocker. In mice, ovulation is induced ~12 hours following the treatment with exogenous gonadotropins, including human chorionic gonadotropin (hCG), which mimics the action of luteinizing hormone (LH). When administered within 6 hours of hCG treatment, UPA is a potent blocker of ovulation. Howev ...[more]

Gene expression profiling of ovaries collected from wild type (WT) mice and progesterone receptor (PR) knock out mice

Project description:Previous studies have shown that PR is a critical regulator of ovulation. The PR-null mice (PRKO) failed to ovulate due to a failure in the rupture of the preovulatory follicles. To experimentally induce ovulation, the wild type and PR null mice (C57BL/6, 24–28 d old) were injected ip with 5 IU of PMSG and 48 h later by 5 IU of hCG. Ovaries were collected at 11 h and total RNA was analyzed using Affymetrix mouse arrays

Gene expression profiling of human endometrial stromal cells transduced with BMP2- and WNT4-adenovirus.

Project description:Our previous studies have shown that bone morphogenetic protein 2 (BMP2), a morphogen belonging to the TGFM-NM-2 superfamily, is markedly induced in human primary endometrial stromal cells (HESC) as they undergo differentiation in response to steroid hormones and cAMP. WNT4 is a downstream target of BMP2 regulation in these cells. To identify the common downstream targets of BMP2 and WNT4 in human endometrial stromal cells, we performed gene expression profling of human ensometrial stromal cell transduced with BMP2 or WNT4 adenovirus. Gene expression profiling revealed that FOXO1, a forkhead family transcription factor and a known regulator of HESC differentiation, is a common downstream mediator of both BMP2 and WNT4 signaling. These studies uncovered a linear pathway involving BMP2, WNT4, and FOXO1 that operates in human endometrium to critically control decidualization. Human endometrial stromal cells were transduced with recombinant adenovirus expressing BMP2, WNT4, or a negative control GFP at MOI 50:1 in 2 ml of culture medium. After transduction for 24 h, the viral particles were removed and the cells were treated with E+P for 3 days to induce decidualization (n=3 for each treatment), pooled total RNA from these cells was then hybridized to high density affymetrix microarrays according to the Affymetrix protocol (Human Genome HG-U133 A2.0 Array) .

Gene expression profiling of mammary epithelial cells isolated from Cuzd1-null and heterozygous mice on day 18 of pregnancy

Project description:Our study revealed that CUZD1 (CUB and zona pellucida-like domain containing protein-1) is a novel target of estrogen regulation in the mouse mammary epithelium. Mice lacking Cuzd1 exhibit delayed ductal outgrowth during puberty and a striking impairment in ductal branching and alveolar development during pregnancy. Ablation of Cuzd1 led to a marked reduction in steroid-induced proliferation of mammary ductal and alveolar epithelium. To identify the downstream targets of Cuzd1 in mammary gland development, we performed gene expression profling of mammary epithlial cells isolated from Cuzd1-null and its heterozygous litteremates on day 18 of pregnancy. The microarray results revealed downregulation of mRNAs corresponding to several members of the epidermal growth factor family in mammary epithelial cells of Cuzd1-null mice. Consequently, the activation of the ERBB receptors, ERBB1 and ERBB4, and their downstream target STAT5, was disrupted in Cuzd1-null mammary tissue. Collectively, these findings support a unique role for CUZD1 as a critical mediator of the steroid-induced proliferation and differentiation of ductal epithelium during pregnancy and lactation. To investigate the functional role of Cuzd1, we created Cuzd1-null mice by homologous recombination using mouse embryonic stem cells. As severe defect was observed in alveolargenesis and lactation of Cuzd1 null mammary gland, we purified mammary epithlial cells from day18 pregnant mice (n=5 for each genotype), purified total RNA from these cells, pooled these samples and then hybridized to high density affymetrix microarrays.

Gene expression profiling of uterine epithelial cells isolated from Msx1Msx2 floxed and Msx1Msx2 ablated mice on day 4 of pregnancy

Project description:Our preliminary study revealed that the homeobox transcription factors, Msx1 and Msx2, are expressed in the mouse uterus during early pregnancy. Further, conditional deletion of Msx1 and Msx2 in mouse uterus leads to implantation failure due to impaired uterine epithelial receptivity. To identify the downstream targets of Msx1Msx2 in the uterus, we performed gene expression profling of uterine epithelial cells isolated from Msx1Msx2-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 Wnts in uterine epithelium of Msx1Msx2-ablated mice. We performed conditional ablation of Msx1Msx2 in the mouse uterus using the PRcre mouse model. we isolated uterine epithelial cells from day4 pregnant mice (n=5 for each genotype). Total RNA was purified from these cells to hybridize to high density affymetrix microarrays.

Gene expression profiling of uterine stromal cells isolated from Hand2 floxed and Hand2 ablated mice on day 4 of pregnancy

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.

Gene expression profiling of C/EBPM-NM-2- and STAT3-deficient human endometrial stromal cells (HESC)

Project description:Our previous studies have shown that C/EBPM-NM-2 plays a critical role in human endometrial stromal decidualization. In order to identify the molecular pathways regulated by C/EBPM-NM-2 during decidualization, we performed gene expression profiling using RNA isolated from normal and C/EBPM-NM-2-deficient human endometrial stromal cells. The microarray results revealed that several key regulators of stromal differentiation, such as BMP2, Wnt4, IL-11RM-NM-1 and STAT3, operate downstream of C/EBPM-NM-2 during decidualization. Further studies revealed that STAT3 is a direct target of C/EBPM-NM-2 and plays an important role in cytokine signal during the decidualization process. Gene expression profiling, using STAT3-deficient HESCs, showed an extensive overlap of pathways downstream of STAT3 and C/EBPM-NM-2 during stromal cell differentiation. We employed a siRNA strategy to suppress C/EBPM-NM-2 or STAT3 mRNA expression in HESCs and then performed microarray analysis to identify its downstream target genes. Further, using a similar strategy, we focused on STAT3, a C/EBPM-NM-2 target gene, and identified the commone pathways downstream of both C/EBPM-NM-2 and STAT3.
