Expression profiling analysis of mouse P4 cerebellum in CitK mutant mice proficient or knockout for P53
  • organism-icon Mus musculus
  • sample-icon 12 Downloadable Samples
  • Technology Badge IconIllumina HiScanSQ

Description

Purpose: Citron kinase (CitK) knockout mice show a severe form of primary microcephaly, associated with ataxia and lethal epilepsy. This phenotype is caused by massive apoptosis occuring during embryonic and post-natal brain development, associated with cytokinesis failure. Cerebellum is the tissue showing highest sensitivity to CitK loss. The clinical phenotype of CitK knockout mice is significantly resued by P53 inactivation. In addition, CitK/P53 double knockout brains have almost normal levels of apoptosis, but display high percentage of binucleated and multinucleated cells. The aim of this study was to analyze the gene expression changes produced in developing neural tissue by CitK loss and to determine which alterations are P53-dependent. expression changes Methods: We analyzed by RNA sequencing total RNA extracted from P4 cerebellum of mice characterized by the following genotypes: 1. CitK +/-, P53 +/- (CTRL); 2. CitK -/-, P53 +/- (CitK-KO); 3. CitK +/-, P53 -/- (P53-KO); 4. CitK -/-, P53 -/- (D-KO). Biological triplicates were analyzed per every genotype. Conclusions: The loss of CitK leads to a strong reduction of the expression of pro-neural genes and induces a P53-related pro-apoptotic gene sets. The analysis of D-KO mice reveals that most of these changes are P53-dependent, but many genes implicated in growth arrest are induced through P53-independent mechanisms. Overall design: Cerebellar mRNA profiles of 4-day old mice of CTRL, CitK-KO, P53-KO and D-KO mice were generated by deep sequencing, in triplicate, using Illumina HiScan SQ

N-octanoyl dopamine treatment of endothelial cells induces the unfolded protein response and results in hypometabolism and tolerance to hypothermia
  • organism-icon Homo sapiens
  • sample-icon 5 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133A 2.0 Array (hgu133a2)

Description

N-octanoyl dopamine (NOD), but not dopamine dose dependently induces the UPR. This was also found for other synthetic N-Acyl dopamine derivates (NADD). Induction of the UPR was dependent on the redox activity of NADD and was not caused by selective activation of a particular UPR sensor. UPR induction did not result in cell apoptosis, yet NOD strongly impaired cell proliferation by attenuation of cells in the S-G2/M phase. Long-term treatment of HUVEC with low NOD concentration showed decreased intracellular ATP concentration paralleled with activation of AMPK. These cells were significantly more resistant to cold inflicted injury.

Temporal Gene Expression Patterns in the skin of D6 null and wild type mice after inflammation with the chemical irritant TPA
  • organism-icon Mus musculus
  • sample-icon 30 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

The chemokine decoy receptor D6 internalises and degrades inflammatory CC chemokines enabling resolution of inflammation. In D6 deficient mice (D6 KO), otherwise innocuous cutaneous inflammatory stimuli induce a grossly exaggerated inflammatory response that bears many similarities to human psoriasis. In the present study we have used transcriptomic approaches to define the molecular make up of this response.

CD24 regulates gene expression in pre-adipocytes in response to IBMX and Dexamethasone stimulation
  • organism-icon Mus musculus
  • sample-icon 9 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 2.0 ST Array (mogene20st)

Description

Previous in vitro studies in our lab have shown that CD24, a cell surface receptor, actively regulates lipid accumulation in adipocytes. But how CD24 regulates this process remains unknown. In order to answer this question, we initially tested to determine if CD24 regulates lipid accumulation by regulating glucose uptake in adipocytes in vitro. We observed that instead, CD24 caused the dysregulation of the expression of 134 genes as determined by DNA microarray analysis. We then validated the expression of select four genes, when CD24 is knocked down during the different stages of adipogenesis in 3T3-L1 pre-adipocytes in vitro. To further confirm the role of these genes, we then determined the expression patterns of these four genes in primary cells undergoing adipogenesis that were isolated from the epididymal and inguinal white adipose tissue depots of CD24 knockout mice. Surprisingly, we found that these genes were dysregulated in the inguinal but not the epididymal depot in vitro. Overall, the data presented here suggests that CD24 is necessary for select gene expression, but not glucose uptake, during adipogenesis in vitro.

Publication Title

CD24 is required for regulating gene expression, but not glucose uptake, during adipogenesis.

Global transcriptome profiling of Oct4/Klf4/Sox2 (3Factor, 3F) + IL6 iPS clones derived from mouse embryonic fibroblasts.
  • organism-icon Mus musculus
  • sample-icon 8 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

Description

We used heterokaryon cell fusion based reprogramming and identified the cytokine IL6 as a potential regulator of reprogramming to pluripotency. We generated iPS clones using the four reprogramming factors (4F) Oct4, Klf4, Sox2, and c-Myc. In addition, iPS clones were generated using only three factors (3F: Oct4, Klf4, amd Sox2) with the addition of the cytokine IL6 to reprogramming culture conditions. Global RNA-Seq of the 3F + IL6 derived iPS clones was done for comparison with 4F-derived iPS clones, mouse embryonic stem cells and mouse embryonic fibroblasts. Overall design: This study includes 8 samples: 2 independently derived 3F + IL6 iPS clones, 2 independently derived 4F iPS clones, 2 biological replicates of mouse D3-GFP ES cells, and 2 biological replicates of mouse embryonic fibroblasts (MEFs). The latter 6 samples are provided as references for the 3F + IL6 iPS clones. Poly-A RNA was isolated and prepared for sequencing using the Illumina TruSeq RNA kit (v2) to generate 50bp reads. Reads were aligned to mm10.

CD40-activation of human B cells
  • organism-icon Homo sapiens
  • sample-icon 7 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133A Array (hgu133a)

Description

Antibody-independent effector functions of B cells, such as antigen presentation and cytokine production, have been shown to play an important role in a variety of immune-mediated conditions such as autoimmune diseases, transplant rejection and graft-versus-host disease. Therapeutic strategies, which interfere with B cell activation could therefore be a useful addition to the current immunosuppressive armamentarium. CD40 is one of the strongest activation stimuli for B cells. The aim of this study was to characterise the gene expression changes that occurr after B cell activation via CD40.

Publication Title

Inhibition of protein geranylgeranylation specifically interferes with CD40-dependent B cell activation, resulting in a reduced capacity to induce T cell immunity.
