Gene expression analysis of the effect of Irx3 knockout in mouse hypothalamus compared with wild-type (in high-fat diet)

ABSTRACT: To establish the roles of Irx3 in molecular and physiological brain phenotypes associated with obesity, we performed transcriptomic analysis (RNA-seq) on hypothalami from Irx3 CRISPR/Cas9 knockout mice and wild-type littermates.

Whereas coding variants often have pleiotropic effects across multiple tissues, noncoding variants are thought to mediate their phenotypic effects by specific tissue and temporal regulation of gene expression. Here, we investigated the genetic and functional architecture of a genomic region within the FTO gene that is strongly associated with obesity risk. We show that multiple variants on a common haplotype modify the regulatory properties of several enhancers targeting IRX3 and < ...[more]

Project description:We performed 4C to analyze long-range interactions between the promoters of Rpgrip1l/Fto, Irx3, Irx5 and Irx6 and a region in the first intron of the FTO gene that has been associated with obesity. 3 whole mouse hypothalami were used to obtain the data.

Next Generation Sequencing of BMDM overexpressing GFP, IRX3-WT, IRX3-S361A and IRX3-S389A

Project description:IRX3 is a transcriptional factor, which play important functions in developmental processes. But the role of IRX3 in immune cells are less studied. So we sequenced mRNA from BMDMs overexpressing GFP, IRX3, as well as two phosphorylation site mutants-S361A and S389A respectively, to address the roles of IRX3 in macrophages.

Cooperative and antagonistic roles for Irx3 and Irx5 in cardiac morphogenesis and postnatal physiology

Project description:Analysis of the roles of Irx3 and Irx5 transcription factors in mouse heart development and postnatal heart function. Results show that show that Irx3 and Irx5 have redundant function in the in the endocardium to regulate atrioventricular canal morphogenesis and outflow tract formation. A postnatal deletion of Irx3 and Irx5 surprisingly results in a restoration of the repolarization gradient that is altered in Irx5 mutant hearts, suggesting a model whereby postnatal Irx3 activity is normally repressed by Irx5. 4 genotypes were analyzed: Irx5+/- (3 samples), Irx3-/-;Irx5+/- (4 samples), Irx5-/- (3 samples), Irx5-/-;Irx3-/- (4 samples). The Irx5+/- samples are the reference.

Frequent derepression of the Iroquois homeobox gene IRX3 in human acute leukemia

Project description:The Iroquois homeodomain transcription factor gene IRX3 is highly expressed in the developing nervous system, limb buds and heart. In adults, expression levels specify risk of obesity. We now report a significant functional role for IRX3 in human acute leukemia. While transcript levels are very low in normal human bone marrow cell populations, high level IRX3 expression is observed in ~30% of patients with acute myeloid leukemia (AML), ~50% of patients with T-acute lymphoblastic leukemia and ~20% of patients with B-acute lymphoblastic leukemia, typically in association with high levels of HOXA9. Expression of IRX3 alone was sufficient to immortalise murine bone marrow stem and progenitor cells, and induce T- and B-lineage leukemias in vivo with incomplete penetrance. IRX3 knockdown induced terminal differentiation of AML cells. Combined IRX3 and Hoxa9 expression in murine bone marrow stem and progenitor cells substantially enhanced the morphologic and phenotypic differentiation block of the resulting AMLs by comparison with Hoxa9-only leukemias, through suppression of a myelomonocytic program. Likewise, in cases of primary human AML, high IRX3 expression is associated with reduced myelomonocytic differentiation. Thus, tissue-inappropriate derepression of IRX3 modulates the cellular consequences of HOX gene expression to enhance differentiation block in human AML.

Expression profiling of microRNA and mRNA on hepatic inflammation in high-fat induced murine model

Project description:The goal of this study was to identify and characterize of miRNA in the regulation of inflammatory responses of high-fat induced inflammation mouse model. In this study, we established a mouse model of high-fat-diet-induced inflammation to gain understanding on the biological functions deregulated by aberrant gene expression based on miRNA and mRNA expression profiling analysis. And then we looked for direct miRNA targets by performing pair-wise correlation coefficient analysis on expression levels of mRNAs and by comparing these results with predicted miRNA targets from TargetScan5.1. A subset of the mice from the Chow and HFD groups were killed after 3 months and 9 months. All animals were weighed and anesthetized with ether. Serum was then obtained from the retro-orbital cavity, and mice were killed before liver tissue collection.
