IL-4 Receptor a Subunit Deficiency Alleviates Murine Intestinal Inflammation In Vivo through the Enhancement of Intestinal Mucosal Barrier Function
  • organism-icon Mus musculus
  • sample-icon 3 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

In the present study we investigate the role of IL-4 receptor a subunit in intestinal inflammation using DSS-induced colitis model. Our finding suggest that IL-4Ra deficiency enhances intestinal mucosal barrier function through the upregulation of NOX1-dependent ROS production, thereby suppressing the development of intestinal inflammation.

Coupling between alternative polyadenylation and alternative splicing is limited to terminal introns
  • organism-icon Homo sapiens
  • sample-icon 4 Downloadable Samples
  • Technology Badge IconIlluminaGenomeAnalyzerIIx

Description

Alternative polyadenylation has been implicated as an important regulator of gene expression. In some cases, alternative polyadenylation is known to couple with alternative splicing to influence last intron removal. However, it is unknown whether alternative polyadenylation events influence alternative splicing decisions at upstream exons. Knockdown of the polyadenylation factors CFIm25 or CstF64 was used as an approach in identifying alternative polyadenylation and alternative splicing events on a genome-wide scale. Although hundreds of alternative splicing events were found to be differentially spliced in the knockdown of CstF64, genes associated with alternative polyadenylation did not exhibit an increased incidence of alternative splicing. These results demonstrate that the coupling between alternative polyadenylation and alternative splicing is usually limited to defining the last exon. The striking influence of CstF64 knockdown on alternative splicing can be explained through its effects on UTR selection of known splicing regulators such as hnRNP A2/B1, thereby indirectly influencing splice site selection. We conclude that changes in the expression of the polyadenylation factor CstF64 influences alternative splicing through indirect effects. Overall design: HeLa cell line was stably transfected with shRNA plasmids targeting CstF64. Total RNA was isolated from CstF64 KD cells and wild-type control cells using Trizol according to manufacturer’s protocols. Samples were deep sequenced in duplicate using the Illumina GAIIx system.

Expression data from VND7 induction line
  • organism-icon Arabidopsis thaliana
  • sample-icon 69 Downloadable Samples
  • Technology Badge Icon Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)

Description

Plants typically contain two different types of cell walls: a primary wall that is being deposited around all growing cells, and a secondary wall that is produced in cells with specialized functions once they have ceased to grow. In Arabidopsis, VND7 is a transcription factor that is sufficient to activate secondary cell wall synthesis. To artificially turn on the secondary cell wall synthesis, VND7 was fused to the activation domain of the herpes virus VP16 protein and the glucocorticoid receptor (GR) domain. Thus, the transgenic plants harbouring the constructs can then be treated with dexamethasone (DEX), a glucocorticoid derivative, to induce the secondary cell wall formation.

Eye-antenna early L3 disc expression profiling in combinations of COX7a-LoF, ATF4-LoF and Notch-GoF
  • organism-icon Drosophila melanogaster
  • sample-icon 16 Downloadable Samples
  • Technology Badge Icon Affymetrix Drosophila Genome 2.0 Array (drosophila2)

Description

Gene expression in larval, early third instar eye-antenna discs was assessed to reveal an ATF4 contribution to target gene induction following COX7a knockdown. As hypothesised, these COX7a-RNAi induced target genes require the transcription factor ATF4 for induction, irrespective of concomitant Notch pathway activation through Delta over-expression.

Comparative gene expression analysis of mesenchymal stem cells (MSC) derived from non-small cell lung cancer (NSCLC) and corresponding normal lung tissue (NLT)
  • organism-icon Homo sapiens
  • sample-icon 9 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

The stromal microenvironment plays a vital role in cancer initiation and progression. We performed a comparative expression profiling of pulmonary MSC derived from NSCLC and corresponding normal lung tissue of 5 newly diagnosed patients. The analysis indicated variable expression of genes involved in DNA repair, apoptosis, proliferation or angiogenesis between NSCLC-MSC and NLT-MSC.

Eye-antenna early L3 disc expression profiling in COX7a-LoF and Notch-GoF
  • organism-icon Drosophila melanogaster
  • sample-icon 10 Downloadable Samples
  • Technology Badge Icon Affymetrix Drosophila Genome 2.0 Array (drosophila2)

Description

Gene expression in larval, early third instar eye-antenna discs was assesed in genotypes with Notch Gain-of-Function (UAS-Delta or UAS-Notch[intra2]) over-expression or mitochondrial COX7a Loss-of-function (UAS-COX7a-RNAi) or a combination of both (UAS-Delta, UAS-COX7a-RNAi). The analysis revealed that, despite a strong genetic interaction between Notch pathway activation and knockdown of COX7a, no transcriptional cooperation or synergy was detectable in early L3 eye-antenna discs. Rather, COX7a knockdown induced a unique transcriptional signature, which further experiments revealed to be mediated by the transcription factor ATF4.

Dysregulation of the circulating and tissue-based renin-angiotensin system in preeclampsia
  • organism-icon Homo sapiens
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Preeclampsia complicates more than 3% of all pregnancies in the United States and Europe. High-risk populations include women with diabetes, dyslipidemia, thrombotic disorders, hyperhomocysteinemia, hypertension, renal diseases, previous preeclampsia, twin pregnancies, and low socioeconomic status. In the latter case, the incidence may increase to 20% to 25%. Preeclampsia is a major cause of maternal and fetal morbidity and mortality. Preeclampsia is defined by systolic blood pressure of more than 140 mm Hg and diastolic blood pressure of more than 90 mm Hg after 20 weeks gestation in a previously normotensive patient, and new-onset proteinuria. Abnormal placentation associated with shallow trophoblast invasion (fetal cells from outer cell layer of the blastocyst) into endometrium (decidua) and improper spiral artery remodeling in the decidua are initial pathological steps.

HeLa cell polyA- RNA-seq
  • organism-icon Homo sapiens
  • sample-icon 1 Downloadable Sample
  • Technology Badge IconIlluminaHiSeq2000

Description

Coilin iCLIP data revealed 42 novel human snoRNAs of intronic origin. To validate their expression and estimate abundance of novel and annotated snoRNAs, we performed RNA-seq on polyA- and rRNA-depleted RNA isolated from HeLa cells. Results show that expression of novel snoRNAs is comparable to the previously annotated snoRNAs. Overall design: 1 replicate of RNA depleted of polyA and ribosomal RNA.

Functional heterogeneity of cancer-associated fibroblasts from human colon tumors shows specific prognostic gene expression signature
  • organism-icon Homo sapiens
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Gene 1.0 ST Array (hugene10st)

Description

Tumor growth and metastasis is controlled by paracrine signaling between cells of the tumor microenvironment and malignant cells. Cancer-associated fibroblasts (CAFs), are functionally important components of the tumor microenvironment. Although some steps involved in the cross-talk between these cells are known, there is still a lot that is not clear. Thus, the addition of, the consideration of microenvironment in the development of the disease, to the clinical and pathological procedures (currently admitted as the consistent value cancer treatments) could lay the foundations for the development of new treatment strategies to control the disease.
