Next Generation Sequencing of β-cat lox(ex3) (Ctrl) mouse and β-cat lox(ex3);Nex-Cre (β-cat overexpression, β-cat Ovp) mouse Transcriptomes

ABSTRACT: Using RNA-seq to sequence the transcriptomes of β-cat lox(ex3) (Ctrl) and β-cat lox(ex3);Nex-Cre (β-cat Ovp) mice, we did not find significant change in the expression level of classical Wnt target genes.

aCGH analysis was performed in the spleen of Î²cat(ex3)osb mice

Project description:Cells of the osteoblast lineage affect homing, number of long term repopulating hematopoietic stem cells (HSCs) HSC mobilization and lineage determination and Blymphopoiesis . More recently osteoblasts were implicated in pre-leukemic conditions in mice. Yet, it has not been shown that a single genetic event taking place in osteoblastscan induce leukemogenesis. We show here that in mice, an activating mutation of Î²-catenin leading to development of acute myeloid leukemia (AML) with common chromosomal aberrationsand cell autonomous progression. Activated Î²-catenin stimulates expression of the Notch ligand Jagged-1 in osteoblasts. Subsequent activation of Notch signaling in HSCprogenitors induces the malignant changes. Demonstrating the pathogenetic role of theNotch pathway, genetic or pharmacological inhibition of Notch signaling ameliorates AML. Nuclear accumulation and increased Î²-catenin signaling in osteoblasts was also identified in 38% ofpatients with MDS/AML. These patients showed increased Notch signaling in hematopoietic cells. These findings demonstrate that genetic alterations in osteoblasts can induce AML, identify molecular signals leading to this transformation and suggest a potential novel pharmacotherapeuticapproach to AML. The present entry describes a comparison of copy numbers of DNA from Î²cat(ex3)osb mice from the mouse spleen with that of WT (C57BL/J Mice) mice. DNA from spleen myeloid cells from Î²cat(ex3)osb mice and WT mice were hybridized to Agilent CGH 244A arrays. DNA from spleen myeloid cells from Î²cat(ex3)osb mice in C57BL/J background was labeled with red dye. DNA from spleen myeloid cells from WT (C57BL/J) mice were labeled with green dye. There were five arrays with DNA from 1 mouse of each genotype per array.

Identification of novel pathways involved in the pathogenesis of human adamantinomatous craniopharyngioma

Project description:Pair-wise comparison between: BAT-gal positive b-catenin accumulating cluster cells (Hesx1Cre/+;Ctnnb1+/lox(ex3);BAT-gal) with BAT-gal negative b-catenin non-accumulating (normal) cells (Hesx1Cre/+;Ctnnb1+/lox(ex3);BAT-gal) from a pretumoral 18.5dpc mouse pituitary.

Analysis of EMCN+ bone marrow cells in Stab2-iCreF3tg/wt Ctnnb1(Ex3)fl/wt mice

Project description:Endothelial-derived Wnt/Ctnnb1-signaling is an important angiocrine regulator. Ctnnb1 gain-of-function (GOF) in sinusoidal endothelial cells was generated via Stab2-iCreF3tg/wt Ctnnb1(Ex3)fl/wt mice to analyze the effects of endothelial β-catenin signaling on bone marrow function. We used microarrays to detail the global programme of gene expression in bone marrow EMCN+ cells with β-catenin (Ctnnb1) gain-of-function compared to Wildtype.

Next Generation Sequencing Facilitates Quantitative Analysis of Wild Type and β-cateninΔ(ex3)/+ liver tissues Transcriptomes

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived retinal transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis Methods: Liver tissues‘ mRNA profiles of 8-week-old wild-type (WT) and liver specific β-cateninΔ(ex3)/+ mice were generated by deep sequencing, in triplicate, using Illumina GAIIx. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. qRT–PCR validation was performed using TaqMan and SYBR Green assays Results: Using an optimized data analysis workflow, Genes differential expression analysis between the WT and β-cateninΔ(ex3)/+ was performed by DESeq2 software between two different groups (and by edgeR between two samples). The genes with the parameter of false discovery rate (FDR) below 0.05 and absolute fold change ≥ 2 were considered differentially expressed genes. Differentially expressed genes were then subjected to enrichment analysis of GO functions and KEGG pathways. Conclusions: Our study represents the first detailed analysis of liver transcriptomes, with 3 biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.

Analysis of gene expression changes in amyloid-beta (ADDL) and CAT-SKL antioxidant treated primary rat neuronal cells

Project description:Amyloid-beta (Aβ)-induced neurotoxicity is a major contributor to the pathologies associated with Alzheimer’s disease (AD). The formation of reactive oxygen species (ROS), and early response induced by the Aβ peptide, plays a significant role in effecting cellular pathogenesis. Here we apply a particularly effective form of exogenous Aβ, i.e., amyloid beta-derived diffusible ligands (ADDLs), to cultured primary cortical/hippocampal neurons to elicit ROS and drive cellular dysfunction. To prevent and even reverse such effects, we employed a cell-penetrating, peroxisome-targeted, protein biologic - called CAT-SKL. We show the recombinant enzyme enters neurons, reverses Aβ-induced oxidative stress, and increases cell viability. Dramatic restorative effects on damaged neuronal processes were also observed. CAT-SKL, a targeted antioxidant, may represent a new therapeutic approach for treatment disorders, like Alzheimer’s disease, where oxidative stress is manifest. Preclinical testing is warranted and ongoing Primary Rat E18 coritical/hippocampal neurons (derived from Sprague Dawley E18 cortical/hippocampus tissue obtained from BrainBits®, Springfield, IL) were treated with ADDLs in the presence or absence of the targeted antioxidant CAT-SKL to investigate genes that displayed altered expression in response to treatmetns total RNA was isolated and analyzed in an Agilent two-color experiment. Two biological replicates of each condition were directly compared, ratios are treated relative to control (untreated)

Mouse liver [beta]-catenin chip-seq

Project description:Given that [beta]-catenin is a well-known transcriptional coactivator, and its transcriptional downstream genes may mediate [beta]-catenin’s action on hepatocarcinogenesis. Here, we performed ChIP-seq to study genome-wide distribution of [beta]-catenin in [beta]-catenin[delta](ex3)/+ livers in quest of the putative genes.

Expression data from E11.5 mouse branchial arch 1 (BA1) - comparison between Ezh2lox/lox and Wnt1Cre Ezh2lox/lox embryos

Project description:Conditional ablation of Ezh2 in the neural crest lineage results in loss of the neural crest-derived mesenchymal derivatives. In this data sheet we determine gene expression analysis in Ezh2lox/lox and Wnt1Cre Ezh2lox/lox in E11.5 mouse BA1 cells. Conditional ablation of Ezh2 in the neural crest lineage was achieved by crossing Wnt1creEzh2lox/wt mice with Ezh2lox/lox mouse lines. We analyzed a total of 6 samples including 3 biological replicates from Ezh2lox/lox embryos and 3 biological replicates from Wnt1cre Ezh2lox/lox embryos.
