Human Initiator / Effector Gene Sets That Regulate Myometrial Contractility During Term and Preterm Labor
  • organism-icon Homo sapiens
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Distinct processes govern the transition from myometrial quiescence to activation during both term and preterm labor. We sought the specific gene sets responsible for initiating term and preterm labor, along with a core set of effector genes necessary for labor independent of gestational age and the underlying trigger. The Effector Gene Set consisted of 49 genes present in both preterm and term labor but absent from non-labor samples. 122 genes were specific to preterm labor (Preterm Initiator Set) and 229 to term labor (Term Initiator Set). The Term Initiator and the Effector Sets reflected predominantly inflammatory processes. Surprisingly, the Preterm Initiator Gene Set reflected molecular and biological events almost exclusive of inflammation. Preterm and term labor differ dramatically in their unique, initiator gene profiles, suggesting alternative pathways underlie these events. Inflammatory processes are ubiquitous to the Term Initiator and the Effector Gene Sets, supporting the idea term parturition is an inflammatory process. The absence of inflammatory processes in the Preterm Initiator Set suggests inflammation is secondary to processes triggering spontaneous preterm birth, and could explain the lack of therapeutic efficacy associated with anti inflammatory/antibiotic regimens.

RNA-seq analysis reveals profound changes in transcript profiles between siCon- and siH19-transfected EVT cells
  • organism-icon Homo sapiens
  • sample-icon 12 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

Description

We used high throughput sequencing to analyze the transcriptional profiling of EVT. By comparing the transcriptional profiling of EVT with or without H19 knockdown, numerous genes showed significantly altered expression as a result of H19 repression. Overall design: HTR cells were transfected with either control siRNA or siH19. 48h later after transfection, total RNA was extracted for library preparation and RNA-seq analysis to compare trancript profiles between siCon and siH19 cells.

  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Deregulated RTK activity has been implicated as a causal leukemogenic factor in the context of molecular aberrations that perturb differentiation in the hematopoietic lineage such as in childhood ALL. A deeper understanding of RTK signaling processes on a system-wide scale will be key in defining critical components of signaling networks. To link RTK activity with in vivo output in primary ALL we took a functional approach, which combined SH2 domain binding, mass spectrometry, and transcriptome analyses. Structure and composition of evolving networks were highly diverse with few generic features determined by receptor and cell type. A combinatorial assembly of varying context-dependent and few generic signaling components at multiple levels likely generates output specificity. PAK2 was identified as a phosphoregulated FLT3 target, whose allosteric inhibition resulted in apoptosis of ALL cells. Our studies provide evidence that a functional approach to leukemia signaling may yield valuable information for a network-directed intervention.

Description

Abstract: Interleukin-10-deficient (Il10-/-) mice serve as a model for inflammatory bowel disease (IBD). The severity of colitis strongly depends on the inbred strain carrying the disrupted Il10 gene: C3H/HeJBir (C3) confers disease susceptibility, whereas C57BL/6J (B6) confers resistance. Genome-wide scans with microsatellite markers on segregrating backcross and F2 populations resulted in the detection of ten colitogenic quantitative trait loci (QTL). The aim of this study was to reduce the large number of candidate genes within the QTL intervals by identifying those genes which are located within the candidate gene intervals and which are differentially expressed in the colon of IBD-susceptible and -resistant strains. Using this combination of QTL mapping and microarray analysis, we identified 16 genes which were differentially expressed between B6- and C3-Il10-/- mice and were located within the candidate gene intervals. Three of these genes (Pla2g2a, Gbp1, Cd14) showed prominent differences in expression levels between B6- and C3-Il10-/- as well as between B6 and C3 wildtype mice and were considered to be major candidate genes. Pla2g2a and Gbp1 are known to be polymorphic between C3 and B6 mice. Expression data for Cd14 were confirmed by real-time RT PCR using specified pathogen free and germfree Il10-/- mice. In conclusion, the large number of candidate genes was reduced to three major candidates by using a combination of QTL mapping and microarray analysis. All three genes play an important role in inflammatory processes and immune response.

Th1/Th17 Immune Response in Rosacea
  • organism-icon Homo sapiens
  • sample-icon 50 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Rosacea is a common chronic inflammatory skin disease of unknown etiology. Our knowledge about an involvement of the adaptive immune system is very limited. We performed detailed transcriptome analysis, qRT-PCR, and quantitative immunohistochemistry on facial biopsies of rosacea patients, classified according to their clinical subtype. As controls, we used samples from healthy controls. Our study shows significant activation of the immune system in all subtypes of rosacea, characterizing erythematotelangiectatic rosacea (ETR) already as a disease with significant influx of proinflammatory cells. The T cell response is dominated by Th1/Th17-polarized immune cells, as demonstrated by significant upregulation of IFN or IL-17, for example. Chemokine expression patterns support a Th1/Th17 polarization profile of the T cell response. Macrophages and mast cells are increased in all three subtypes of rosacea, while neutrophils reach a maximum in papulopustular rosacea. Our studies also provide evidence for activation of plasma cells with significant antibody production already in ETR, followed by a crescendo pattern towards phymatous rosacea. In sum, Th1/Th17 polarized inflammation and macrophage infiltration is an underestimated hallmark in all subtypes of rosacea. Therapies directly targeting the Th1/Th17 pathway are promising candidates in the future treatment of this skin disease.

Expression data from colorectal cancers

Description

Wiskott-Aldrich syndrome (WAS) predisposes patients to leukemia and lymphoma. WAS is caused by mutations in the protein WASP which impair its interaction with the WIPF1 protein. Here, we aim to identify a module of WIPF1-coexpressed genes and to assess its use as a prognostic signature for colorectal cancer, glioma, and breast cancer patients. Two public colorectal cancer microarray data sets were used for discovery and validation of the WIPF1 co-expression module. Based on expression of the WIPF1 signature, we classified more than 400 additional tumors with microarray data from our own experiments or from publicly available data sets according to their WIPF1 signature expression. This allowed us to separate patient populations for colorectal cancers, breast cancers, and gliomas for which clinical characteristics like survival times and times to relapse were analyzed. Groups of colorectal cancer, breast cancer, and glioma patients with low expression of the WIPF1 co-expression module generally had a favorable prognosis. In addition, the majority of WIPF1 signature genes are individually correlated with disease outcome in different studies. Literature gene network analysis revealed that among WIPF1 co-expressed genes known direct transcriptional targets of c-myc, ESR1 and p53 are enriched. The mean expression profile of WIPF1 signature genes is correlated with the profile of a proliferation signature. The WIPF1 signature is the first microarray-based prognostic expression signature primarily developed for colorectal cancer that is instrumental in other tumor types: low expression of the WIPF1 module is associated with better prognosis.
