Project description:We report transcriptional profiles of liver from control and p21-AAV8 administered no-pregnant mice and pregnant mice at dpc8 and dpc16. We revealed that genes related to carbohydrate transport and regulators of glucose and glycogen metabolism were down regulated in AAV-p21 administered liver at dpc16.

Project description:We report transcriptional profiles of each liver lobular zone from non-pregnant mice and pregnant mice at dpc8 and dpc16. By RNA-sequencing of LCM-isolated each zonal cells, we revealed that genes related to actin cytoskeleton, extracellular matrix organization and vascularization were enriched in the PA (zone2) and CV (zone3) zones at dpc8 and cell division related genes were enriched in the PV (zone1) zone at dpc8. At dpc16, genes related to metabolism, catabolism and xenobiotic process were enriched in all zones.

Project description:ABSTRACT:Pregnancy requires a higher functional beta cell mass and this is associated with profound changes in the gene expression profile of pancreatic islets. Taking Tph1 as a sensitive marker for pregnancy-related islet mRNA expression in female mice, we previously identified prolactin receptors and placental lactogen as key signalling molecules. Since beta cells from male mice also express prolactin receptors, the question arose whether male and female islets have the same phenotypic resilience at the mRNA level during pregnancy. We addressed this question in vitro, by using islet tissue culture with placental lactogen and in vivo, by transplanting male or female islets into female acceptor mice. Additionally, the islet mRNA expression of pregnant prolactin receptor deficient mice was compared with that of their pregnant wild-type littermates. When cultured with placental lactogen, or transplanted in female recipients that became pregnant (day 12.5), male islets induced the ‘islet pregnancy gene signature’, which we defined as the 12 highest induced genes in non-transplanted female islets at day 12.5 of pregnancy. In addition, serotonin immunoreactivity was also induced in these male transplanted islets at day 12.5 of pregnancy. In order to investigate the importance of prolactin receptors in these mRNA changes we used a prolactin receptor deficient mouse model. For the 12 genes of the signature, which are highly induced in control pregnant mice, no significant induction of mRNA transcripts was found at day 9.5 of pregnancy. Together, our results support the key role of placental lactogen as a circulating factor that can trigger the pregnancy mRNA profile in male and female beta cells. Islets were isolated from non-prengant (NP) and pregnant (day 9.5) PRLR+/+ and PRLR-/- mice for RNA extraction and hybridization on Affymetrix microarrays. For every condition 3 biological replicates were used.

Project description:Affymetrix Gene ST 1.0 arrays were performed on total RNA obtained from ovaries of 5 female mice (pregnant or non-pregnant; mock or MCMV infection). Mice were infected 9.5 days post conception with 2x10e05 PFU MCMV i.v.. RNA was prepared at 5 days post infection (14.5 days post conception). Total RNA prepared from ovaries of 5 mice per condition was pooled and subjected to microarray analysis. Data were normalised using RMA.

Project description:Mammary glands were collected from 8 pregnant (12.5 day) mice and 8 non-pregnant adult (10 week old) female mice. Epithelial cells were FACS sorted from the pregnant mice. Cells from the adult mice were FACS sorted as basal or luminal. Freshly sorted cells were submitted to a Fluidigm C1 System machine for single cell capture and cDNA synthesis. Cells were visualized under the microscope to ensure integrity of the captured single cells prior to cDNA preparation. Libraries were prepared using the Nextera XT kit and sequencing was carried out on an Illumina NextSeq 500 to achieve 75 bp paired-end reads.

Project description:To compare tumor associated macrophage (TAM) from naïve and sepsis surviving mice we have employed Agilent microarrays slides with almost 60,000 genes (39,430 mRNA and 16,251 long non coding RNAs). Other experiments we conducted demonstrated TAM accumulation was increased in post-sepsis subjects. For this reason, we asked if TAM from post-sepsis mice could also exhibit a different gene expression profile. Sepsis was induced by cecal and ligation puncture. Naïve mice were used as control group. All animals were treated with ertapenem (20 mg/kg, i.p., 6 hours after surgery, and then each 12 hours for 3 days). B16-F10 melanoma (30,000 cells) were injected subcutaneously at day 14 after sepsis induction. Fourteen days after tumor inoculation, animals were killed and tumors were harvested and digested (collagenase and DNAse). TAM was isolated by a Percoll gradient (70/30) followed by a 1-hour adhesion protocol, reaching a purity of ~75%. For comparative reasons, we assessed TAM from post-sepsis (n = 4), TAM from naïve mice (n = 4), bone marrow derived macrophage from naïve (n = 4) and from post-sepsis (n = 4), M1-polarized macrophage (n = 4) and M2-polarized macrophage (n = 4). We found only minor gene expression differences between TAM from naïve and from post-sepsis mice (61 genes were up-regulated and 98 genes were down-regulated, fold-change > 0.58 or < -0.58, and p < 0.01). We found genes related to leukocyte activation were down-regulated in TAM from post-sepsis mice (e.g. Ccr7, Cd86, H2-Ab1), as well as genes related to antigen processing and presentation of peptide or polysaccharide antigen via MHC class II (H2-DMb1, Cd74, H2-Eb1, H2-Ob). A gene related to M2 polarization was up-regulated (Marco). Also, we found a down-regulation of Nfkbid in post-sepsis-derived TAM. This led us to hypothesize TAM from post-sepsis mice exhibit a more M2-like phenotype, which may in part contribute to post-sepsis tumor expansion. Three independent experiments were conducted for TAM obtaining, each experiment using n = 4 for naïve and n = 4 for post-sepsis. We selected the 4 best within a group of 12 samples, following A260/280 and A260/230 ratios. For bone marrow derived macrophage from naïve and from post-sepsis, and for M1 and M2-polarized macrophage, we conducted two independent experiments using n = 3 per group. The best 4 samples in each group was selected to microarray processing and analysis.

Project description:To study the effect of pregnancy on mouse mammary epithelial subpopulations, epthelial cells derived from virgin or pregnant (12.5 day pregnant) mice were isolated using fluorescence-activated cell sorting. After elimination of haematopoietic and endothelial cells, two distinct epithelial subpopulations were sorted using antibodies against CD29 and CD24. Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as mammary stem cell enriched (CD29hiCD24+) and luminal (CD29loCD24+) respectively (ref: Shackleton et al, Nature 2006). Microarray profiling was used to compare gene expression profiles of the two subpopulations in 12.5 day pregnant and virgin mice. For each biological replicate, mammary gland from virgin or 12.5 day pregnant FVB/NJ mice were collected and digested to obtain a single cell suspension. CD45-CD31-TER119- cells were then sorted based on the expression of cell surface markers CD24 and CD29. There were 4 pools of pregant mice and 3 pools of virgin mice.
