IKK is essential for the development and maintenance of Marginal zone and Follicular B cells
  • organism-icon Mus musculus
  • sample-icon 2 Downloadable Samples
  • Technology Badge Icon

Description

IKK kinase is essential for the B cell maturation and secondary lymphoid organ development. In the current study, we evaluated the role of IKK in the marginal zone and follicular B lymphocyte development by genetically deleting IKK from the B cell lineage using CD19-Cre mice. The loss of IKK did not affect the normal development of early B cell progenitors. However, a significant decline was observed in the percentage of immature B lymphocytes, mature marginal zone and follicular B cells along with a severe disruption of splenic marginal and follicular B cell zones. A gene expression analysis performed on the RNA extracted from the newly formed B cells (B220+IgMhi) revealed that IKK deficiency produces significant changes in the expression of genes involved in MZ and FO B lymphocyte survival, homing and migration. And several among those genes identified belong to G protein family. Specifically, we validated the upregulated expression of regulator of G protein signaling 13 (RGS13), which is a GTPase activating protein (GAP) that negatively regulates G protein signaling and impede B cell migration. Likewise, promigratory B lymphocyte receptor, the sphingosine-1-phosphate receptor 3 (SIPR3) that couple to Gi showed significantly reduced expression. In addition, an in silico analysis of gene product interactions revealed NF-B signaling pathways to be a major gene regulating networks perturbed with IKK deletion. Taken together, this study reveals IKKNF-B and G protein signaling axis to be central for the MZ and FO B cells survival, maintenance, homing and migration.

Expression data from E12.5 NSP cells, CTL v REST shRNA
  • organism-icon Mus musculus
  • sample-icon 5 Downloadable Samples
  • Technology Badge Icon

Description

REST is a master regulator of genes that are involved in the acqusition of neuronal fate. The role of REST is not well understood so we attempted to investigate the role of REST in the development of neural cells by analysing the genes that are upregulated when REST is knocked down via shRNA

Publication Title

REST regulates the pool size of the different neural lineages by restricting the generation of neurons and oligodendrocytes from neural stem/progenitor cells.

Brain transcriptome variation among behaviorally distinct strains of zebrafish (Danio rerio)
  • organism-icon Danio rerio
  • sample-icon 1 Downloadable Sample
  • Technology Badge Icon

Description

Domesticated animal populations often show profound reductions in predator avoidance and fear-related behavior compared to wild populations. These reductions are remarkably consistent and have been observed in a diverse array of taxa including fish, birds, and mammals. Experiments conducted in common environments indicate that these behavioral differences have a genetic basis. In this study, we quantified differences in fear-related behavior between wild and domesticated zebrafish strains and used microarray analysis to identify genes that may be associated with this variation.

Genetic architecture of murine skin inflammation and tumor susceptibility
  • organism-icon Mus spretus, Mus musculus, Mus musculus x mus spretus
  • sample-icon 4 Downloadable Samples
  • Technology Badge Icon

Description

Gene expression in self-renewing epithelial tissues is controlled by cis- and trans-activating regulatory factors that mediate responses to exogenous agents capable of causing tissue damage, infection, inflammation, or tumorigenesis. We used network construction methods to analyze the genetic architecture of gene expression in normal mouse skin in a cross between tumor-susceptible Mus musculus and tumor-resistant Mus spretus. We demonstrate that gene expression motifs representing different constituent cell types within the skin such as hair follicle cells, haematopoietic cells, and melanocytes are under separate genetic control. Motifs associated with inflammation, epidermal barrier function and proliferation are differentially regulated in mice susceptible or resistant to tumor development. The intestinal stem cell marker Lgr5 is identified as a candidate master regulator of hair follicle gene expression, and the Vitamin D receptor (Vdr) links epidermal barrier function, inflammation, and tumor susceptibility.

Investigating genes regulated by mir-155 in a mouse macrophage cell line
  • organism-icon Mus musculus
  • sample-icon 2 Downloadable Samples
  • Technology Badge Icon

Description

Mammalian microRNAs (miRNAs) are emerging as key regulators of the development and function of the immune system. Here, we report a strong but transient induction of miR-155 in mouse bone marrow after injection of bacterial lipopolysaccharide (LPS) correlated with granulocyte/monocyte (GM) expansion. Demonstrating the sufficiency of miR-155 to drive GM expansion, enforced expression in mouse bone marrow cells caused GM proliferation in a manner reminiscent of LPS treatment. However, the mir-155-induced GM populations displayed pathological features characteristic of myeloid neoplasia. Extending possible relevance to human disease, miR-155 was overexpressed in the bone marrow of patients with acute myeloid leukemia (AML). Furthermore, miR-155 repressed a subset of genes implicated in hematopoietic development and disease. These data implicate miR-155 as a contributor to physiological GM expansion during inflammation and to certain pathological features associated with AML, emphasizing the importance of proper miR-155 regulation in developing myeloid cells during times of inflammatory stress.

Sustained expression of microRNA-155 in hematopoietic stem cells causes a myeloproliferative disorder.

Gene therapy of Mpl -/- mouse LSK cells
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon

Description

Comparison of Mpl-/- mouse LSK cells, either treated with control (GFP) or Mpl lentivirus. Lineage negative bone marrow cells were isolated and transduced and transplanted into Mpl-/- recipient mice. After transplantation and follow up mice were sacrificed and LSK (lineage negative, Sca-1 positive, cKit positive) cells were isolated by FACS. RNA was isolated using RNeasy Micro Kit (Qiagen GmbH, Hilden, Germany) and RNA was amplified for microarray hybridization using the Nugen Ovation system (Nugen Technologies, AC Bemmel, Netherlands). The resulting material was hybridized to Affymetrix Mouse 430 2.0 arrays. RMA normalization and summarization was performed in R 2.10 using Bioconductor packages. The aim was to show the normalization of Mpl associated gene expression.

Publication Title
