Detailed Investigations of Proximal Tubular Function in Imerslund-Gräsbeck Syndrome

BMC Medical Genetics 2013, 14:111 http://www.biomedcentral.com/1471-2350/14/111 RESEARCH ARTICLE Open Access Detailed investigations of proximal tubular function in Imerslund-Gräsbeck syndrome Tina Storm1, Christina Zeitz2,3,4, Olivier Cases2,3,4, Sabine Amsellem2,3,4, Pierre J Verroust1,2,3,4, Mette Madsen1, Jean-François Benoist6, Sandrine Passemard7,8, Sophie Lebon8, Iben Møller Jønsson9, Francesco Emma10, Heidi Koldsø11, Jens Michael Hertz12, Rikke Nielsen1, Erik I Christensen1* and Renata Kozyraki2,3,4,5* Abstract Background: Imerslund-Gräsbeck Syndrome (IGS) is a rare genetic disorder characterised by juvenile megaloblastic anaemia. IGS is caused by mutations in either of the genes encoding the intestinal intrinsic factor-vitamin B12 receptor complex, cubam. The cubam receptor proteins cubilin and amnionless are both expressed in the small intestine as well as the proximal tubules of the kidney and exhibit an interdependent relationship for post-translational processing and trafficking. In the proximal tubules cubilin is involved in the reabsorption of several filtered plasma proteins including vitamin carriers and lipoproteins. Consistent with this, low-molecular-weight proteinuria has been observed in most patients with IGS. The aim of this study was to characterise novel disease-causing mutations and correlate novel and previously reported mutations with the presence of low-molecular-weight proteinuria. Methods: Genetic screening was performed by direct sequencing of the CUBN and AMN genes and novel identified mutations were characterised by in silico and/or in vitro investigations. Urinary protein excretion was analysed by immunoblotting and high-resolution gel electrophoresis of collected urines from patients and healthy controls to determine renal phenotype. -

Genetic, Metabolic and Clinical Characteristics of Maturity Onset Diabetes of the Young
European Journal of Endocrinology (1998) 138 233±239 ISSN 0804-4643 REVIEW Genetic, metabolic and clinical characteristics of maturity onset diabetes of the young Gilberto Velho and Philippe Froguel1 INSERM U-342, HoÃpital Saint Vincent de Paul, Paris, France and 1CNRS EP10, Institut Pasteur de Lille et CHU, Lille, France (Correspondence should be addressed to G Velho, INSERM U-342, HoÃpital Saint Vincent de Paul, 82 Avenue Denfert Rochereau, 75014 Paris, France) Abstract Maturity onset diabetes of the young (MODY) is a genetically and clinically heterogeneous subtype of non-insulin-dependent diabetes mellitus (NIDDM) characterised by early onset, autosomal dominant inheritance and a primary defect in insulin secretion. To date, three MODY genes have been identi®ed on chromosomes 20q (MODY1/hepatic nuclear factor (HNF)-4a), 7p (MODY2/glucokinase) and 12q (MODY3/HNF-1a). Mutations in MODY2/glucokinase result in mild chronic hyperglycaemia as a result of reduced pancreatic beta-cell responsiveness to glucose, and decreased net accumulation of hepatic glycogen and increased hepatic gluconeogenesis after meals. In contrast, MODY1 and MODY3 are characterised by severe insulin secretory defects, and by major hyperglycaemia associated with microvascular complications. The role of the three known MODY genes in susceptibility to the more common late-onset NIDDM remain uncertain. Genetic studies seem to exclude a role as major susceptibility genes, but leave unresolved whether they may have a minor role in a polygenic context or an important role in particular populations. European Journal of Endocrinology 138 233±239 MODY is a monogenic form of NIDDM MODY3/HNF-1a (11, 12) respectively, can cause this form of diabetes. -

M1BP Cooperates with CP190 to Activate Transcription at TAD Borders and Promote Chromatin Insulator Activity

Lei 1,2 1234567890():,; Genome organization is driven by forces affecting transcriptional state, but the relationship between transcription and genome architecture remains unclear. Here, we identified the Drosophila transcription factor Motif 1 Binding Protein (M1BP) in physical association with the gypsy chromatin insulator core complex, including the universal insulator protein CP190. M1BP is required for enhancer-blocking and barrier activities of the gypsy insulator as well as its proper nuclear localization. Genome-wide, M1BP specifically colocalizes with CP190 at Motif 1-containing promoters, which are enriched at topologically associating domain (TAD) borders. M1BP facilitates CP190 chromatin binding at many shared sites and vice versa. Both factors promote Motif 1-dependent gene expression and transcription near TAD borders genome-wide. Finally, loss of M1BP reduces chromatin accessibility and increases both inter- and intra-TAD local genome compaction. Our results reveal physical and functional inter- action between CP190 and M1BP to activate transcription at TAD borders and mediate chromatin insulator-dependent genome organization. 1 Nuclear Organization and Gene Expression Section, Bethesda, MD, USA. 2 Laboratory of Biochemistry and Genetics, Bethesda, MD, USA. 3 Laboratory of Cellular and Developmental Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD, USA. ✉ 4These authors contributed equally: Shue Chen, Leah F. -

Klein et al.# In 2020, 146,063 deaths due to pancreatic cancer are estimated to occur in Europe and the United States combined. To identify common susceptibility alleles, we performed the largest pancreatic cancer GWAS to date, including 9040 patients and 12,496 controls of European 1234567890():,; ancestry from the Pancreatic Cancer Cohort Consortium (PanScan) and the Pancreatic Cancer Case-Control Consortium (PanC4).
