Transcription profiling by array of mouse liver with Cyld inactivation
ABSTRACT: Effect of Cyld inactivation in liver. The Cyld gene was conditionally inactivated specifically in the liver by crossing mice carrying floxed exon 9 allele of Cyld with Alfp-Cre transgenic mice. Liver RNAs from Cyld lox/lox-AlfpCre mice were compared with RNAs prepared from the livers of wild type littermates.

Project description:Bone morphogenetic proteins (BMPs) are transforming growth factor β (TGFβ) family members that regulate the post-implantation and mid-gestation stages of pregnancy. In this study we discovered that signaling via activin-like kinase 3 (ALK3/BMPR1A), a BMP type 1 receptor, is necessary for blastocyst attachment. To understand the role of ALK3 in the luminal uterine epithelium, we obtained the gene expression profiles of isolated luminal uterine epithelium from 3.5dpc control and Alk3 cKO mice. Gene expression profiling of isolated luminal uterine epithelium from control and Alk3 cKO mice. two group comparison
Project description:To elucidate the effect of senescence in mouse colorectal tumor, the transcriptome of enterocytes from CKI alpha deletion mutants (CKI alpha KO), CKI alpha/p53 double deletion mutants (CKI alpha/p53 DKO) and CKI alpha heterozygous mice (CKI alpha Het) were determined by RNAseq.
Project description:To screen mRNAs specifically regulated by mTORC1, a global mRNA expression profile in colon epithelial cells (CECs) from mice with or without CECs-specific TSC1 knockout (KO) was developed using microarray. Wile-type or CECs-specific TSC1 KO mice with experimental colitis were sacrificed, with CECs harvested and subjected to total RNA extraction.
Project description:Kruppel-like factor 5 gene was deleted (Cre-lox) system specifically in cardiomyocytes (aMHC-promoter-driven expression of Cre) and RNA was purified from total hearts (TRIZOL method) following perfusion of the heart with PBS. Basal levels cardiac RNA was analyzed with whole genome microarray chips. There were two groups of mice: 4 mice that had KLF5 gene floxed without expressing Cre recombinase (control group) and 4 mice that were expressing Cre in cardiomyocytes and therefore KLF5 gene was deleted and thus not expressed in this particular cell type.
Project description:To screen mRNAs specifically regulated by mTORC1, a global mRNA expression profile in calvarial osteoblasts (OBs) from mice with or without OB-specific Tsc1 knockout was developed using microarray. Wild type (WT) or OB-specific Tsc1 knockout (KO) mice were sacrificed, with calvarial osteoblasts harvested and subjected to total RNA extraction.
Project description:Five-week-old male mice (Mus musculus, ICR) were exposed to single As, single Fe and combined As and Fe for 90 days. A total of 40 mice were randomly assigned to control and three metal-treated groups. Nine mice were applied in every group. For control group, mice were fed with pure water. For three metal-treated groups, mice were feed with 3mg/L As, 5mg/L Fe and 3mg/L As + 5mg/L Fe, respectively. After exposure, mice were anaesthetized under isoflurane followed by exsanguination. Livers were removed, and hepatic RNA for each mouse was immediately extract. The gene expression profiles for control and three metal-treated groups were determined by the GeneChip Mouse Gene 1.0 ST arrays. Biological meanings of DEGs were analyzed by pathway analysis. DEGs were mapped to different biological pathways according to Kyoto encyclopedia of genes and genomes (KEGG) pathway database (http://www.genome.ad.jp/kegg/ pathway.html) using SBC Analysis System of Shanghai Biotechnology Corporation (http://sas.ebioservice.com/).
Project description:We have determined the cistrome and transcriptome for the nuclear receptor liver receptor homolog-1 (LRH-1) in the exocrine pancreas. Chromatin immunoprecipitation (ChIP)-seq and RNA-seq analyses reveal that LRH-1 directly induces expression of genes encoding digestive enzymes and secretory and mitochrondrial proteins. LRH-1 cooperates with the pancreas transcription factor 1-L complex (PTF1-L) in regulationg exocrine pancreas-specific gene expression. Elimination of LRH-1 in adult mice reduced the concentration of several lipases and proteases in pancreatic fluid and impaired pancreatic fluid secretion in response to cholecystokinin. Thus, LRH-1 is a key regulator of the exocrine pancreas-specific transcriptional network required for the production and secretion of pancreatic fluid. input and Lrh1 ChIP
