Project description:Adam10, a cell surface protease, cleaving many proteins including TNF-alpha and E-cadherin. Here we investigate the genome wide effects of Adam10 knock out on the transcriptome. Commercial microarrays (Affymetrix Mouse Gene ST 1.0) were used to generate genome wide mRNA profiles. Mouse tissue samples from n=4 wiltype skin and n=4 Adam10 knockout skin were used in the study.

Project description:During the past two decades although many genes e.g.,Gdf5, Wnt9a, Noggin etc. have been identified and characterized in joint development, still a comprehensive understanding of molecular network operational in articular cartilage morphogenesis is far from being drawn. This might be due to incompleteness in the number of molecules identified. We used microarray profiling to identify chicken articular cartilage specific genes. We decided to conduct microarray-based transcriptome comparison of HH38 (E12) and HH40 (E14). As it is difficult to clearly dissect out articular cartilage even at these late stages we decided to identify the transcripts that are enriched in the transient + articular cartilage (TC+AC) over pure transient cartilage (TC) thus using TC as control or reference samples

Project description:Identify the therapeutic targets/pathways of Osteoarthritis (OA), the most frequent joint disease. Surgery-induced cartilage degeneration is used as an experimental model for OA in mice. An inducible cartilage-specific c-Fos loss-of-function model is generated by combining c-fos floxed and Col2a1-CreERT mice. Since c-Fos mutant mice have more severe phenotype than c-Fos wild type mice, we focused on c-Fos-related signaling pathway in the articular cartilage.

Project description:In a transgenic mouse model of Alzheimer disease (AD), cleavage of the amyloid precursor protein (APP) by the α-secretase ADAM10 prevented amyloid plaque formation and alleviated cognitive deficits. Furthermore, there was a positive influence of ADAM10 over-expression on neurotransmitter-specific formation of synapses and on synaptic plasticity. To assess the influence of ADAM10 on the gene expression profile in the brain we performed microarray analysis using RNA isolated from brains of five month old mice over-expressing either the α-secretase ADAM10 or a dominant-negative mutant (dn) of this enzyme. As compared to non-transgenic wild-type mice, 355 genes were found to be differentially expressed in ADAM10 transgenic mice and 143 genes in dnADAM10 mice. A higher number of genes was found to be differentially regulated in double-transgenic mouse strains additionally expressing the human APP V717I mutant (APP[V717I]). Thus, α-secretase cleavage of over-expressed APP[V717I] alters CNS gene expression additionally. Keywords: genetic modification

Project description:Objective : To study molecular changes in the articular cartilage and subchondral bone of the tibial plateau from mice deficient in frizzled related protein (Frzb) compared to wild-type mice by transcriptome analysis. Methods : Gene-expression analysis of the articular cartilage and subchondral bone of 3 wild-type and 3 Frzb-/- mice was performed by microarray. Pathway analysis of differentially expressed genes between 3 wild-type and 2 Frzb-/- samples was explored with PANTHER, DAVID and GSEA bioinformatics tools. Activation of the WNT pathway was analyzed using western blot. The effects of Frzb gain and loss of function on chondrogenesis and cell proliferation was examined using ATDC5 micromasses and mouse ribcage chondrocytes. Results : Extracellular matrix-associated integrin and cadherin pathways, as well as WNT pathway genes were upregulated in Frzb-/- samples. Several WNT receptors, target genes, and other antagonists were upregulated, but no difference in active β-catenin was found. Analysis of ATDC5 cell micromasses overexpressing FRZB indicated an upregulation of aggrecan and Col2a1, and downregulation of molecules related to damage and repair in cartilage, Col3a1 and Col5a1. Silencing of Frzb resulted in downregulation of aggrecan and Col2a1. Pathways associated with cell cycle were downregulated. Ribcage chondrocytes derived from Frzb-/- mice showed decreased proliferation compared to wild-type cells. Conclusions : Our analysis provides evidence for tight regulation of WNT signaling, shifts in extracellular matrix components and effects on cell proliferation and differentiation in the articular cartilage - subchondral bone unit in Frzb-/- mice. These data further support an important role for FRZB in joint homeostasis and highlight the complex biology of WNT signaling in the joint. Gene-expression analysis of the articular cartilage and subchondral bone of 3 wild-type and 3 Frzb-/- mice was performed by microarray. Pathway analysis of differentially expressed genes between 3 wild-type and 2 Frzb-/- samples was explored with PANTHER, DAVID and GSEA bioinformatics tools.

Project description:Myocardial infarction (MI) contributes to cardiac mortality and morbidity. After myocardial infarction the innate immune response is pivotal in clearing of tissue debris as well as scar formation, but exaggerated cytokine and chemokine secretion with subsequent leukocyte infiltration also leads to further tissue damage. Post-translational regulation of cytokine / chemokine signaling occurs via ectodomain shedding through a disintegrin and metalloproteases (ADAMs). Here, we address the value of targeting a previously unknown ADAM10 / CX3CL1 axis in the regulation of neutrophil recruitment early after MI. We show that myocardial ADAM10 is distinctly upregulated in biopsies from patients with ischemia-driven cardiomyopathy and correlates with heart failure progression. Intriguingly, upon MI in mice, pharmacological treatment with the ADAM10 inhibitionor GI254023X as well as genetic cardiomycyte-specific ADAM10 deletion improves survival with markedly enhanced heart function and reduced scar size. Mechanistically, this is driven by abolished ADAM10-mediated CX3CL1 ectodomain shedding followed by diminished IL-1β-dependent inflammation, reduced neutrophil bone marrow egress as well as myocardial tissue infiltration. Genetic cardiomycyte-specific ADAM10 deletion confirmes the small-molecule data and leads to improved cardiac function and reduction in inflammatory markers after ischemic myocardial injury. Thus, our data shows a conceptual insight into how acute MI induces chemotactic signaling via ectodomain shedding in cardiomyocytes.

Project description:The spleen contains phenotypically and functionally distinct cDC1 and cDC2 subpopulations, which each can be divided into several smaller and less-well characterized subsets. Despite advances in understanding the complexity of DC ontogeny and function by transcriptional programming, the significance of post-translational modifications in controlling tissue-specific cDC (subset) immunobiology remains elusive. Here, we identified the cell surface-expressed A-disintegrin-and-metalloproteinase 10 (ADAM10) as an essential regulator of cDC1 and cDC2 homeostasis in the splenic marginal zone (MZ). Mice with a CD11c-specific deletion of ADAM10 (ADAM10ΔCD11c) exhibited a complete loss of splenic ESAMhi cDC2A, because ADAM10 controlled their commitment, differentiation, survival, and EBI2-mediated localization within the MZ. Moreover, we discovered that ADAM10 is a molecular switch regulating cDC2 subset heterogeneity in the spleen, as this unbalanced cDC2A homeostasis in the absence of ADAM10 was compensated for by the emergence of a novel Clec12a+ cDC2B subset, closely resembling cDC2 generally found in peripheral lymph nodes. Moreover, in ADAM10ΔCD11c mice terminal differentiation of cDC1 was abrogated, resulting in reduced numbers of Langerin+ cDC1.
