Project description:This study aims to investigate the interactions of mutagenic lesions from diethylnitrosamine (DEN) treatment of mouse livers with such processes as replication, transcription, and interaction of DNA with proteins. Liver samples of 15-day old (P15) untreated C3H/HeOuJ mice were isolated and flash-frozen. ATAC-seq was performed to identify the regions of open chromatin and sites likely to be occupied by transcription factors.
Project description:This study aims to investigate the interactions of mutagenic lesions from diethylnitrosamine (DEN) treatment of mouse livers with such processes as replication, transcription, and interaction of DNA with proteins. Liver samples of 15-day old (P15) untreated C3H/HeOuJ mice were isolated and flash-frozen. ChIP-seq was performed to identify CTCF binding sites in livers of ten pooled individuals. The experiment was done with five biological replicates with a matched input library.
Project description:2-3 month old female C57Bl/6J mice were intravenously infected with 2x10^6 focus forming units of lymphocytic choriomeningitis virus strain Clone-13. Whole liver tissue was harvested in duplicated from uninfected control mice, uninfected 123d old mice, and from infected at 2, 8, 30, 60, and 123 days post infection. Three TMT 6-plex runs were carried out to monitor the changes in liver protein abundance during the entire course of infection. The first run included samples from day 2 and day 8 after infection along with the uninfected controls. Similarly, the second run included uninfected controls and samples from day 30 and day 60 after infection. The third run included samples day 123 after infection, the corresponding age matched control that was left uninfected for 123 days and the uninfected controls used in the other two runs. The uninfected controls were included in all the three runs as an internal control to monitor reproducibility between the runs.
Project description:RNA profiling of inflammatory chemokines, cytokines and receptors in AUTOMACS sorted F4/80+ and CD11c+ cells from lungs of 6-12 week old wild-type C3H/HeN mice before and after 14-day Mycoplasma pulmonis infection
Project description:Sexual dimorphism of gene expression is commonly observed in mammalian tissues, including liver. To assess sexual dimorphisms in gene expression, we profiled the transcriptome of liver tissue from 20-week old male and female mice of the C57BL/6N (B6) and C3H/HeN (C3) inbred mouse strains using RNA-seq. These two inbred mouse strains exhibit phenotypic differences in liver biology, as they are at opposite ends of the spectrum of spontaneous hepatocellular carcinoma incidence; C3 mice are highly susceptible to develop spontaneous liver tumors as a function of age, while B6 mice are extremely resistant. Overall, these datasets provide insight into the underlying gene expression patterns that should be considered when assessing sex differences in mouse liver.
Project description:Using full-genome arrays, the expression of all XMEs was examined during fetal (gestation day (GD) 19), neonatal (postnatal day (PND) 7), prepubescent (PND30), middle age (12 mon), and old age (18 and 24 mon) in the C57Bl6/J mouse liver and compared to young adults. Fetal and neonatal life stages had a dramatic effect on XME expression compared to the relatively minor effects of old age. At all life stages except PND30 down-regulated genes outnumbered up-regulated genes. The altered XMEs included those in all of the major metabolic phases including phase I (alcohol and aldehyde dehydrogenase and Cyp genes), phase II (aldo-keto reductase, glutathione-S-transferases, sulfotransferases and UDP-glucuronosyl transferases) and phase III (transporters). We have generated a comprehensive catalog of XME hepatic gene changes through the life stages of the mouse that can be used to predict chemicals and chemical classes different life stages are more sensitive to. Some CEL files used in this study have been submitted through GSE21224. Keywords: gene expression/microarray We characterized gene expression changes in the developing mouse liver at gestational days (GD) 19), neonatal (postnatal day (PND) 7), prepubescent (PND30), middle age (12 mon), and old age (18 and 24 mon) in the C57Bl6/J mouse liver using full-genome microarrays and compared these changes to that in the adult liver.. We also compared results to GD19, PND32, and PND67 C3H mice. Total RNA was isolated from liver samples and gene expression analyzed using Affymetrix Mouse 430 2.0 GeneChips. Data from 28 samples, four mice in each of the age groups for C57BL/6 and C3H, were analyzed.
Project description:In this study we generated mice with inducible over-expression of microRNA Mir483, using a transgene inserted at the Rosa26 locus. Whole transcriptome analysis was performed by RNA-seq in livers collected from 15-week old adult mice (over-expressors and controls).
Project description:Liver transcriptome profiling of liver specific miR-122 knockout (miR-122loxP/loxP Alb-Cre) and control (miR-122loxP/loxP) male mice. Expression profile of several hundred mRNAs that include miR-122 targets were altered in miR-122 KO livers. Loss of miR-122 in the germ line resulted in significant changes in hepatic gene expression profile. Among the upregulated genes many are direct targets of miR-122 GSM517838-GSM517847: Liver transcriptome profiling of liver specific miR-122 knockout and control male mice. Total liver RNA from 8 week old five control and five liver-specific miR-122 knock out male mice (C57/BL6J background) GSM791601-GSM791604: Liver transcriptome profiling of germ-line miR-122 knockout and control male mice. Liver RNA from 5 week old control (floxed) and miR-122KO mice were analyzed by mouse whole transcriptome profiling.
