Neural cell adhesion molecule 1 (NCAM1; CD56) promotes leukemogenesis and confers drug resistance in acute myeloid leukemia.

Project description:Neural cell adhesion molecule 1 (NCAM1; also known as CD56) is expressed in up to 20% of acute myeloid leukemia (AML) patients. Expression of NCAM1 is widely used as a marker of minimal residual disease; however, the biological function of this cell surface protein in AML remains elusive. In this study we investigated the impact of aberrant NCAM1 expression on leukemogenesis, drug resistance and its role as a biomarker to guide therapy.Gene expression profiling was performed with RNA-seq in three cell lines (SKM-1, NOMO-1, MOLM-14) after doxycycline-mediated induction of scrambled shRNA or shNCAM1 at timepoint 72 hours.

Isoform-specific regulation of NCAM1 gene expression in ischemic cardiomyopathy

Project description:Although ischemic cardiomyopathy (ICM) is the leading cause of chronic heart failure, one of the most common diseases overall, many aspects of the molecular pathogenesis of ICM still remain to be clarified. It has been We have previously shown that the neural cell adhesion molecule (NCAM1, CD56) is upregulated in ischemic cardiomyopathy by novel isoforms of the transcription factor RUNX1 (AML1) and, in the current study, we show that this upregulation is attributed exclusively to the NCAM1 isoform CD56-140kD. Moreover, we show that the upregulation of CD56-140kD has proapoptotic and antiproliferative effects on cardiomyocytes in vitro as well as inducing mitochondrial damage and reducing the capacity for Ca2+-uptake. As loss of cells and negative inotropy have previously been identified as major components in the development of ischemic cardiomyopathy, these data suggest that the upregulation of CD56-140kD may play a relevant role in the pathogenesis of ICM and therapeutic strategies targeting this molecule may prove to be valuable tools in the management of this very common and often fatal disease in the future.

Gene regulatory programs of NK cells show that NCAM1 (CD56) and KIRs are controlled by genetically polymorphic distal regulatory elements [CITE-seq]

Project description:Owing to their immunoprotective properties, natural killer (NK) cells are critical for the innate response to pathogens, as well as a new wave of cancer immunotherapy that harnesses natural cytotoxicity. We sought to understand the genetic and epigenetic drivers behind human specific NK cell receptors, so that we can better understand the underlying cellular function. Here, we present a transcriptomic, proteomic (CITE-seq), and chromatin (single nuclei ATAC-seq and Hi-C) analysis of human peripheral NK cell subsets, uncovering key regulatory programs governing NK cell differentiation. Through integrative multi-omics, we demonstrate that CD56bright versus CD56dim NK cell subsets have differential distal regulatory element (DRE) landscapes, with fewer accessible DREs in the CD56dim NK cells. We combine epigenetic, chromatin looping, and human genetic data to show mechanisms governing the NCAM1 (encoding CD56) and KIR loci. For example, we identify NCAM1 DREs that bind STAT in most NK cells, while identifying a genetic cohort that has motifs for binding repressive BLIMP1 at the DRE and resulting in less CD56 expression. Together, our findings reveal novel epigenetic and transcriptomic systems for regulation of NK cells cytotoxicity and diversity, deepening our understanding of their function and how transcription factor networks govern CD56bright versus CD56dim phenotypes.

NCAM1: A Novel Autoantigen in Membranous Lupus Nephritis

Project description:Membranous lupus nephritis is a frequent cause of nephrotic syndrome in patients with systemic lupus erythematosus. Unlike phospholipase A2 receptor or thrombospondin type 1 domain containing 7A-associated membranous nephropathy, where known antibodies can be detected within sera by indirect immunofluorescence and/or enzyme-linked immunosorbent assay, it is not possible to monitor disease activity in membranous lupus nephritis where the target autoantigens are mostly unknown. Determination of the target autoantigen has diagnostic significance, informs prognosis, and allows for non-invasive monitoring of disease activity in serum. We utilized mass spectrometry for antigen discovery of laser capture microdissected glomeruli from formalin-fixed paraffin embedded tissue and tissue IgG immunoprecipitation studies from frozen kidney biopsy tissue. We identified neural cell adhesion molecule 1 (NCAM1) to be a target antigen in membranous lupus nephritis and within rare cases of primary membranous nephropathy. The prevalence of NCAM1-associated membranous neuropathy was 5.7% of cases of membranous lupus nephritis. NCAM1 co-localizes with IgG within glomerular immune deposits. Additionally, serum from NCAM1 patients showed reactivity to NCAM1 recombinant protein. The presence of anti-NCAM1 antibodies in sera could allow for non-invasive monitoring of the disease. We propose that NCAM1 is a target autoantigen in a subset of patients with membranous lupus nephritis. Future studies are needed to determine whether anti-NCAM1 antibody levels correlate with disease activity or response to therapy.

Gene expression analysis for CD56- T, NK, CD56+ T cells, and iNKT cells

Project description:A small subset of T cells also expresses kiler-cell immunoglobulin-like receptors (KIRs). We find that KIR+ T cells primarily reside in the CD56+ T population. However, little is known on how these cells are different from the conventional CD56- T, NK, and iNKT cells. We used microarray profiling to compare and determine the distinctive differences of CD56+ T cell and its KIR subsets when compared to the conventional CD56- T, NK and iNKT cells. Lymphocyte subsets were sorted from human peripheral blood mononuclear cells with FACSAriaII (BD Biosciences, San Jose, CA) using anti-CD3, anti-CD56, anti-CD14, anti-KIR2DL1, anti-KIR2DL2/3, anti-KIR3DL1 and anti-TCRValpha24 antibodies. The purity of CD3+CD56- T cells, CD3-CD56+ NK cells, CD3+CD56+ T cells, KIR-CD3+CD56+ T cells, and KIR+CD3+CD56+ T cells were more than 98% in all experiments. The purities of iNKT cells for TCRValpha24 and CD1d-tetramer were >95% and >90%, respectively. RNA pre-amplification, labeling and hybridization on Human Genome U133Plus 2.0 GeneChip array were performed in the St. Jude Hartwell Center for Bioinformatics & Biotechnology microarray core facility according to the manufacturer’s instructions (Affymetrix, Santa Clara, CA).

Activation of a NCAM1 expressing progenitor cell population in adult human kidney epithelia

Project description:NCAM1+ subpopulation of adult human kidney epithelial cells (hKEpC) can be specifically activated in vitro to stem-like cells that de-differentiate and recapitulate embryogenesis. We used microarrays to detail the global programme of gene expression in the NCAM1+ sub-population in comparison to NCAM1-.

Interactomes of neural cell adhesion molecule 1 and the metal ion transporter ZIP6 in mouse NMuMG epithelial cells with transforming growth factor beta 1-induced fibroblastoid morphology

Project description:The prion protein (PrP) evolved from the subbranch of ZIP metal ion transporters comprising ZIPs 5, 6 and 10, raising the prospect that the study of these ZIPs may reveal insights relevant for understanding PrP function. PrP and ZIP6 are required for the execution of a cellular program known as epithelial-to-mesenchymal transition (EMT). Polysialylation of neural cell adhesion molecule 1 (NCAM1) during EMT is also controlled by PrP. Here we report the ZIP6 interactome and ZIP6-dependent NCAM1 interactome in a mouse cell EMT model.
