Description
Mutations in the LMNA gene causes set of disorders collectively referred to as laminopathies that include dilated cardiomyopathy. Lamin A/C proteins a components of nuclear lamina forms distinct nuclear domains called lamina associated domains (LADs). The roles of LADs in DCM is not known. To identify LADs and characterize their associations with CpG methylation and gene expression in human cardiac myocytes isolated from patients with DCM and controls we performed Chromatin immunoprecipitation-sequencing (ChIP-Seq), reduced representative bisulfite sequencing (RRBS), and RNA-sequencing (RNA-Seq) in 5 control and 5 DCM hearts with defined pathogenic variants in the LMNA gene. LADs are redistributed in DCM, are associated with CpG methylation and suppressed transcription, contributing to the pathogenesis of DCM in laminopathies. Overall design: integrated analysis of ChIP-seq for LMNA from Cardiac myocytes and RNA-seq and RRBS from 5 control and 5 DCM human heart sample

Description
This experiment aims to identify the biological pathways and diseases associated with the cytokine Interleukin 13 (IL-13) using gene expression measured in peripheral blood mononuclear cells (PBMCs). Overall design: The experiment comprised of samples obtained from 3 healthy donors. The expression profiles of in vitro IL-13 stimulation were generated using RNA-seq technology for 3 PBMC samples at 24 hours. The transcriptional profiles of PBMCs without IL-13 stimulation were also generated to be used as controls. An IL-13R-alpha antagonist (Redpath et al. Biochemical Journal, 2013) was introduced into IL-13 stimulated PBMCs and the gene expression levels after 24h were profiled to examine the neutralization of IL-13 signaling by the antagonist.

Description
Translocations involving the MLL genes are frequently found in Acute Myeloid Leukemia (AML) and are associated with poor prognosis. The MLL fusion proteins act as aberrant transcription factor activating a transcriptional program that transforms the cells, potentially through collaboration with other transcription factors. To investigate this we searched gene expression profiles from patients with MLL-rearranged AML compared with normal hematopoietic progenitor cells for transcriptional regulators and found targets of C/EBP to be up-regulated in the AML samples, suggesting that C/EBP might collaborate with MLL fusion proteins in the initial transformation process. We could show that transformation by MLL fusion proteins is dependent on C/EBP activity both in early progenitors as well as in GMPs. In contrast, C/EBP was found to be indispensable in an already established leukemia. These results suggest that C/EBP play an important role in the early transforming event of leukemogenesis.

Description
Whole genome microarrays were probed with total mRNA from PTD-DRBD GAPDH siRNA treated H1299 cells at 12 h and 24 h. Using a 1.6x fold increase/decrease filter of cellular mRNAs, we detected a dramatic reduction in the target GAPDH mRNA along with a limited number of both up and down regulated genes. The up regulated genes were reduced in numbers and to nearly background 1.6x levels at 24 h, while the down regulated genes increased slightly in numbers and maintained a similar magnitude at 24 h. In contrast, lipofection treated cells showed both a dramatic increase in both the total number of genes altered and the magnitude of the increase. In addition, the numbers of genes affected increased between 12 h and 24 h, suggesting that lipofection of siRNAs into cells results in a substantial alteration to the transcriptome and may thereby confound interpretation of experimental outcomes. Moreover, the GAPDH specific knockdown was significantly smaller than PTD-DRBD mediated knockdown.

Description
To investigate the role of the transcription factor ERG in hematopoiesis we generated Erg heterozygous knockout and conditional Erg knockout mice. We found that several hematopoietic cell types were decreased in these mice. To define Erg downstream target genes in hematopoietic stem cells, we sorted Lineage-, Sca-1+, c-kit+, CD150+, CD48- cells from Erg +/- mice for gene expression analysis. To define Erg downstream target genes in hematopoietic progenitors, we sorted multipotent progenitors (Lineage-, Sca-1+, c-kit+, CD150-) from Erg -/- mice for gene expression analysis.

Description
G-CSF is a hemopoietic growth factor that has a role in steady state granulopoiesis, as well as in mature neutrophil activation and function. We developed a neutralizing monoclonal antibody to the murine G-CSF receptor (G-CSFR), which antagonizes binding of murine G-CSF and inhibits G-CSFR signalling. Anti-G-CSFR rapidly halts the progression of established disease in collagen antibody-induced arthritis (CAbIA). Neutrophil accumulation in joints is inhibited, without rendering animals neutropenic, suggesting an effect on homing to inflammatory sites. Neutrophils in the blood and arthritic joints of anti-G-CSFR treated mice show alterations in cell adhesion receptors, while anti-G-CSFR suppresses local production of proinflammatory cytokines and chemokines known to drive tissue damage. Our aim in this study was to use differential gene expression analysis of joint and blood neutrophils to more thoroughly understand the effect of G-CSFR blockade on the inflammatory response following anti-G-CSFR therapy in CAbIA.
