Cyclin D1 determines estrogen depependent signaling in mouse mammary gland.

ABSTRACT: Ovariectomized virgin Ccnd1-/- and Ccnd1+/+ mice (5 weeks of age) were allowed to recuperate for 2 weeks. The mice were assigned to either replacement pellets containing E2 (0.75 mg, 60-day release) or pellet containing placebo. Mice were sacrificed at day 7 after pellet implantation. RNA extracted from mammary glands (3 each group) was labeled and used to probe Affymetrix 430_2.0 arrays. Six separate control Ccnd1+/+ C57BL/6 were compared to six Ccnd1-/- C57BL/6 mice. 3 mice in each group treated with placebo and three mice treated with E2

Cyclin D1 Determines Androgen Dependent DNA Damage Sensing and Repair

Project description:Murine prostate epithelial cells (PECs) were obtained from Ccnd1-/- and Ccnd1+/+ FvB mice (2-3 months of age). RNA extracted from PECs (3 technical replicates for each group) was labeled and used to probe Affymetrix 430_2.0 arrays. Three control Ccnd1+/+ PECs were compared to three Ccnd1+/+ PECs.

Liver tissue from hormone treated C57BL/6J mice versus pool C57BL/6J mice of chow diet Liver

Project description:The purpose of this experiment was to determine the expression traits in animals of inbred strain C57BL/6J, treated with gonadal hormones. (N=40, 20 males and 20 females). Liver tissue from the hormone treated group consists of 40 female and male C57BL/6J mice fed a chow diet containing 4% fat (Ralston-Purina Co., St. Louis, MO) until 8 weeks of age and then were gonadectomized at 8 weeks of life, implanted with hormone pellets at 12 weeks, and sacrificed at 14 weeks. Male and female mice of the hormone treated groups received subcutaneous implants of either 0.5 mg estradiol (E2) pellet (plasma yield of 300 picogram/ml) or a 5 mg dihydrotestosterone (DHT) pellet (plasma yield of 1-2 nanogram/ml), designed to release over 21 days, (Innovative Research of America, 17B-estradiol: Cat. No. E-121 0.5mg/pellet, 5a-dihydrotestosterone: Cat. No. A-16). Control mice were treated with the placebo pellet (Innovative Research of America, placebo: Cat. No. C-111). At 14 weeks mice were sacrificed, after a 12-hour fast, Liver tissue were dissected and flash frozen in LN2 and stored at -80Â°C. All sample were compared to a common pool created from equal portions of RNA from each of the samples. Keywords=hormone treated Mouse liver Tissue

Real-time quantitative PCR analysis of mouse lungs after influenza A infection

Project description:Age-matched BALB/c female mice were implanted subcutaneously with slow release estradiol (E2) pellets (35 mg/pellet/mouse) or similar-sized placebo pellets .One week post-implantation, mice were infected intranasally with a sublethal dose of H5N1 A/Vietnam/1203/2004 vaccine reassortant bearing a monobasic HA cleavage site. Mouse lungs were harvested on day 1 post infection and total RNA was extracted using QIAgen RNeasy microarray tissue mini kit. A total of 100 µg high-quality RNA was reverse transcribed using RT2 Easy First Strand Kit (QIAgen). Resultant cDNA was used as the template along with Profiler™ PCR Array Mouse Signal Transduction PathwayFinder™ kit (QIAgen) to quantitate gene expression activated by E2 in response to H5N1 infection.

microRNA repertoire of wild-type C57BL/6 mice T cell blasts and their secreted small extracellular vesicles (Evs)

Project description:T cell blasts were obtained from wild-type C57BL/6 mice. Six-day culture blast supernatants were ultracentrifuged for small EV obtention and small EV pellet obtained after from 100,000g ultracentrifugation and T cell blasts RNA were isolated for small RNA sequencing; (N=3) independent experiments

17β-estradiol accelerates ovarian tumour progression in vivo though the upregulation of GREB1

Project description:Exogenous 17β-estradiol (E2) accelerates the progression of ovarian cancer in the transgenic tgCAG-LS-TAg mouse model of the disease. We hypothesized that E2 has direct effects on ovarian cancer cells and this study was designed to determine the molecular mechanisms by which E2 accelerates ovarian tumour progression. Mouse ovarian cancer ascites (MASE2) cell lines were derived from tgCAG-LS-TAg mice. Following intraperitoneal engraftment of MASE2 into SCID mice, exogenous E2 significantly decreased the survival time and increased the tumour burden. Microarray analysis performed on cells derived from mouse ovarian cancer ascites (MASE2) treated with and without E2 indicated that E2 treatment caused the upregulation and downregulation of genes involved in cell differentiation, proliferation and migration. In particular, Greb1 that has been also identified as a hormone-responsive gene in breast cances, was upregulated in mouse tumour cells treated with E2. Three biological replicates (MASE2 tumours grown in SCID mice, see growth protocol) were analyzed for both conditions of addition of E2 or placebo.

Estrogen and high-fat diet induced alterations of endometrial transcriptome profile in ovariectomized C57BL/6 mice

Project description:Unopposed estrogen stimulation and insulin resistance are known to play important roles in endometrial cancer (EC), but the relationship between these two factors and how they contribute to endometrial lesions is not completely understood. To investigate the endometrial transcriptome profiles and the associated molecular pathway alterations, we established an ovariectomized C57BL/6 mouse model treated with subcutaneous implantation of the 17-β estradiol (E2) pellet and/or high-fat diet (HFD) to mimic sustained estrogen stimulation and insulin resistance. We used microarrays to detail the global program of gene expression underlying the mice endometrium and indentified distinct classes of E2 and/or high-fat diet related ncRNA during this process.

Expression analysis in pancreatic and liver tissues of diabetic db/db mice in response to dietary supplementation with selenate

Project description:Investigation of gene expression level changes in pancreatic and liver tissues of diabetic db/db mice supplemented with selenate, compared to the diabetic db/db mice administered placebo. Fasting blood glucose levels increased continuously in diabetic db/db mice administered placebo (DMCtrl) but decreased gradually in selenate-supplemented diabetic db/db mice (DMSe) and approached normal values when the experiment ended. The size of pancreatic islets increased, causing the plasma insulin concentration to double in DMSe mice compared with that in DMCtrl mice. Two six chip studies using total RNA respectively isolated from pancreatic and liver tissues of three selenate-supplemented diabetic db/db mice, and three diabetic db/db mice administered placebo.

Nanostring miRNA exprssion profiling analysis of splenocytes from 17-β estradiol (E2) and synthetic 17α-ethinyl estradiol (EE) exposed feamle NZB/WF1 lupus mice

Project description:We used the NanoString mouse nCounter miRNA expression platform to compare the miRNA expression profiles of spelnocytes from placebo-, E2, and EE exposed NZB/WF1 mice. We found that EE exposure has a more profound effect than E2 on miRNA genes expression in splenocytes
