Project description:Microarray analysis of male and female CD-1 mouse liver was carried out at 3, 4, and 8 wk of age to elucidate developmental changes in gene expression from the pre-pubertal period to young adulthood. A large number of sex-biased and sex-independent genes showed significant changes during this developmental period. Notably, sex-independent genes involved in cell cycle, chromosome condensation, and DNA replication were down regulated from 3 wk to 8 wk, while genes associated with metal ion binding, ion transport and kinase activity were up regulated. A majority of genes showing sex differential expression in adult liver did not display sex differences prior to puberty, at which time extensive changes in sex-specific gene expression were seen, primarily in males. Thus, in male liver, 76% of male-specific genes were up regulated and 47% of female-specific genes were down regulated from 3 to 8 wk of age, whereas in female liver 67% of sex-specific genes showed no significant change in expression. In both sexes, genes up regulated from 3 to 8 wk were significantly enriched (p < E-76) in the set of genes positively regulated by the liver transcription factor HNF4α, as determined in a liver-specific HNF4α knockout mouse model, while genes down regulated during this developmental period showed significant enrichment (p < E-65) for negative regulation by HNF4α. Significant enrichment of the developmentally regulated genes in genes subject to positive and negative regulation by pituitary hormone was also observed. Nine sex-specific transcription factors showed pubertal changes in expression and may contribute to the developmental changes that onset after 3-4 wk. Overall, the observed changes in gene expression during postnatal liver development reflect the deceleration of liver growth and the induction of specialized liver functions, with widespread changes in sex-specific gene expression primarily occurring in male liver.

Overall, the observed changes in gene expression during postnatal liver development reflect the deceleration of liver growth and the induction of specialized liver functions, with widespread changes in sex-specific gene expression primarily occurring in male liver. Liver RNA isolated from the following six groups of CD-1 mice was used in the present study: 3 wk old male (M) mice (n = 10; 5 per each pool) and female (F) mice (n = 10; 5 per each pool); 4 wk old male mice (n = 12; 6 per each pool) and female mice (n = 12; 6 per each pool); 8 wk old male mice (n = 12; 6 per each pool) and female mice (n = 12; 6 per each pool). These RNA pools were used in seven separate sets of competitive hybridization experiments: 1) 3 wk M vs. 3 wk F; 2) 4 wk M vs. 4 wk F; 3) 8 wk M vs. 8 wk F; 4) 3 wk M vs. 8 wk M; 5) 4 wk M vs. 8 wk M; 6) 3 wk F vs. 8 wk F; 7) 4 wk F vs. 8 wk F. Fluorescent labeling of RNA and hybridization of the Alexa 555-labeled (green) and Alexa 647-labeled (red) aRNA samples to Agilent Mouse Gene Expression 4x44k v2 microarrays (Agilent Technology, Palo Alto, CA; catalog # G4846A-026655) were carried out, with dye swapping for each of the seven hybridization experiments to eliminate dye bias. Two microarrays, one for each mixed cDNA sample, were hybridized for each of the seven fluorescent reverse pairs, giving a total of 14 microarrays.

Project description:Liver samples were isolated from postnatal day 15 (P15) untreated mice and then flash frozen: Mus musculus musculus (C57BL/6J), Mus musculus castaneus (CAST), and Mus caroli (CAROLI). DEN-induced liver tumours and background liver tissue were collected from 37-week old C57BL/6J mice. ATAC-seq was performed to identify the open regions of the genome.

Project description:This study aimed to investigate transcriptional differences between liver tumours that were chemically-induced in five strains and species of mouse and rat. Male mice (Mus musculus domesticus C3H/HeOuJ and C57BL/6J, Mus musculus castaneus CAST/EiJ, and Mus Caroli CAROLI/EiJ) and rats (Fischer F344) were treated with diethylnitrosamine (DEN) to induce liver tumours. After tumour dissection, genomic DNA and RNA were simultaneously isolated and purified for library preparation and sequencing. Additional liver tissue samples were collected and processed in parallel: untreated liver from infant mice (15-day old, P15) and juvenile rats (56-day old, P56); untreated adult liver tissue; DEN-exposed adult liver tissue; spontaneous liver tumours.

Project description:We explored the microevolutionary trends of CTCF binding evolution by preforming ChIP-seq experiments in five closely related Mus strains, subspecies and species: Mus musculus domesticus, Mus musculus castaneus, Mus spretus, Mus caroli and Mus pahari. All experiments were performed in adult male liver samples in 3 biological replicates and with an input control set. Complementary RNA-seq data from this same study have been deposited in ArrayExpress under accession numebr E-MTAB-5768 ( https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-5768 ).

Project description:We analyzed KDM1A (LSD1) occupancy in the Xi during somatic cell reprogramming of female mouse cells. We use MEFs from hybrid embryos by crossing male Mus spretus and female Mus musculus domesticus C57BL/6J to distiguish genome DNA from the Xi. We found a possible physical and/or functional regulation of KDM1A during the X chromosome reactivation in the intiation site on the Xi.

Project description:In development, timing is of the utmost importance, and the timing of various developmental processes are often changed during evolution. We measured the timing of gene expression changes in the brains of two species of mice throughout postnatal development. Mus musculus and Mus spretus mice were bred at the MPI-EVA mouse facility. Whole brain samples were collected from mice of 3 different age classes: newborns, pups and young adults. RNA extracted from the dissected tissue was hybridized to Affymetrix MG-430 2.0 GeneChip arrays.

Project description:We compared gene expression differences in the polytypic species complex Mus musculus (Mus musculus musculus, Mus musculus domesticus, Mus musculus castaneus and Mus musculus ssp) with that of Mus spretus via oligonucleotide microarrays representing more than 20,000 genes. Analysis of the results by two way ANOVA statistics suggests that the most genes with significant differences in expression levels among the subspecies are found in liver and kidney and the least in testis. This picture is different when one compares with Mus spretus, where the largest number of differences is found in testis. Keywords: multi-species comparison

Project description:We analyzed a transcriptional landscape of the Xi during somatic cell reprogramming of female mouse cells. We use MEFs from hybrid embryos by crossing male Mus spretus and female Mus musculus domesticus C57BL/6J to monitor allele-specific transcripts from the Xi. We could capture the earliest phase of X chromosome reactivation and found that a subset of genes clustered near the centromere display an early reactivation on the Xi.
