Whole blood transcript profiling of rheumatoid arthritis patients
  • organism-icon Homo sapiens
  • sample-icon 83 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

The whole blood was collected pre-treatment from rheumatoid arthritis patients starting the anti_TNF therapy. All patients were nave to anti_TNFs. The disease activity was measured using the DAS28 score at the pre-treatment visit1 (DAS28_v1) and 14 weeks after treatment visit3 (DAS28_v3). The response to the therapy was evaluated using the EULAR [European League Against Rheumatism] definition of the response. The objective of the data analysis was to identify gene expression coorelating with response as well as to identify genes that differentiate responders versus non-responders pre-treatment. The results of this investigation identified 8 trainscripts that predict responders vs. non-responders with 89% accuracy.

Gene expression profiling during cardiac maturation, hypertrophy and after KD of TET2
  • organism-icon Mus musculus
  • sample-icon 12 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000, NextSeq 500

Description

Methylation at 5-cytosine (5-mC) is a fundamental epigenetic DNA modification associated recently with cardiac disease. In contrast, the role of 5-hydroxymethylcytosine (5-hmC) – 5-mC's oxidation product – is unknown in the context of the heart. Here, we assess the hydroxymethylome in embryonic, neonatal, adult and hypertrophic mouse cardiomyocytes, showing that dynamic modulation of hydroxymethylated DNA is associated with specific transcriptional networks during heart development and failure. DNA hydroxymethylation marks gene bodies of highly expressed genes and distal regulatory regions with enhanced activity. Pathological hypertrophy is characterized by a partial shift towards a fetal-like distribution pattern. We further demonstrate a regulatory function of TET2 and provide evidence that the expression of key cardiac genes, such as Myh7 is modulated by TET2-mediated 5-hmC deposition on the gene body and at enhancers in cardiac cells. We thus provide the first genome-wide analysis of 5-hmC in the cardiomyocyte, and establish the role of this epigenetic modification in heart development and disease Overall design: Profiling of the transcriptome of embryonic, neonatal, adult, 1 week hypertrophic cardiomyocytes, sh-control and sh-TET2 cardiomyocytes. Two biological replicates were profiled for each cell type.

Gene expression profiling of cardiomyocyte-enriched populations isolated from mice subject to transverse aortic constriction (TAC) and treated with BIX-01294 for 1 week
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge IconIllumina MouseWG-6 v2.0 expression beadchip

Description

The role of the histone mehyltrasferase G9a (also known as Ehmt2) in cardiac hypertrophy has not been studied extensively. To address how G9a promotes cardiac hypertrophy, we assessed the gene expression signature defined by G9a in cardiomyocytes (CM) of mice subject to transverse aortic constriction (TAC) for 1 wk, a surgical procedure that causes cardiac hypertrophy following the induction of pressure overload. To this end, we compared the expression profiles of CMs isolated from mice treated with the G9a inhibitor BIX-01294 and control groups (untreated and DMSO-treated mice at baseline and after TAC). The expression profiles were defined by Illumina arrays .

Gene expression profiling of cardiomyocyte-enriched populations isolated from G9a-KO and Cre mice
  • organism-icon Mus musculus
  • sample-icon 4 Downloadable Samples
  • Technology Badge IconNextSeq 500

Description

The role of the histone mehyltrasferase G9a (also known as Ehmt2) in heart has not been extensively studied. To identify the genes regulated by G9a in the normal heart, we first generated a conditional, cardiac-specific KO mouse for this gene using the Cre-Lox approach, crossing G9a flox/flox mice with aMHC-MerCreMer mice (Cre mice were used as controls). Then, we sequenced total RNA (Total-RNA-seq) from cardiomyocyte-enriched populations isolated from G9a-KO and Cre mice, and compared the two expression profiles. Overall design: Profiling of the transcriptome of cardiomyocyte-enriched populations isolated from G9a-KO and Cre mice. Two biological replicates were profiled for each cell type.

Microarray Analysis of Lymphatic Tissue Reveals Stage-Specific, Gene-Expression Signatures in HIV-1 Infection
  • organism-icon Homo sapiens
  • sample-icon 52 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Untreated HIV-1 infection progresses through acute and asymptomatic stages to AIDS. While each of the three stages has well-known clinical, virologic and immunological characteristics, much less is known of the molecular mechanisms underlying each stage. Here we report lymphatic tissue microarray analyses revealing for the first time stage-specific patterns of gene expression during HIV-1 infection. We show that while there is a common set of key genes with altered expression throughout all stages, each stage has a unique gene-expression signature. The acute stage is most notably characterized by increased expression of hundreds of genes involved in immune activation, innate immune defenses (e.g.MDA-5, TLR-7 and -8, PKR, APOBEC3B, 3F, 3G), adaptive immunity, and in the pro-apoptotic Fas-Fas-L pathway. Yet, quite strikingly, the expression of nearly all acute-stage genes return to baseline levels in the asymptomatic stage, accompanying partial control of infection. In the AIDS stage, decreased expression of numerous genes involved in T cell signaling identifies genes contributing to T cell dysfunction. These common and stage-specific, gene-expression signatures provide new insights into the molecular mechanisms underlying the host response and the slow, natural course of HIV-1 infection.
