Publication number: 20220119516Abstract: The invention relates to the domain of anemia, iron overload and myeloid malignancy. The inventors identify a variant transcript of ERFE specific of SF3B1MUT MDS that contributes to increased concentration of ERFE protein leading to hepcidin suppression and iron accumulation in patients. This transcript contains an in-frame added intronic sequence of 12 nucleotides not inducing a stop codon that may be translated into a variant protein with an additional 4 amino acids. By using deep mass spectrometry, they identified a peptide corresponding to the added polypeptide VPQF (SEQ ID NO: 5) demonstrating the active production of a variant protein by bone marrow erythroblasts of patients with a SF3B1-mutated MDS. This variant can be used as a pertinent biomarker of clonal erythropoiesis for monitoring treatments of anemia in SF3B1MUT patients.Type: ApplicationFiled: January 15, 2020Publication date: April 21, 2022Inventors: Michaela FONTENAY, Olivier KOSMIDER, François GUILLONNEAU, Léon KAUTZ, Samar ALSAFADI, Carine LEFEVRE, Marc-Henri STERN, Alexandre HOUY

Patent number: 11203788Abstract: The present invention concerns an in vitro method for diagnosing a myeloid tumour or a lymphoid tumour in a subject, which comprises the step of analyzing a biological sample from said subject by (i) detecting the presence of a mutation in the Ten Eleven Translocation protein family member 2 gene (TET2) coding for the polypeptide having the sequence SEQ ID NO: 2, and/or (ii) analyzing the expression of the TET2 gene; wherein the detection of such a TET2 mutation, of the absence of expression of TET2 or of the expression of a truncated TET2 is indicative of a subject developing or predisposed to develop a myeloid tumour or a lymphoid tumour.Type: GrantFiled: April 8, 2020Date of Patent: December 21, 2021Assignees: INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE (INSERM), INSTITUT GUSTAVE-ROUSSY, ASSISTANCE PUBLIQUE-HOPITAUX DE PARIS, CENTRE HENRI BECQUEREL, UNIVERSITE PIERRE ET MARIE CURIE, UNIVERSITE PARIS-SUDInventors: Franck Viguie, Olivier Bernard, Michaela Fontenay, Christian Bastard, Francois Delhommeau, William Vainchenker

Patent number: 9675590Abstract: The present invention provides methods and pharmaceutical compositions designed to intervene in this defective process and to promote or restore erythrocyte maturation in individuals suffering from a myelodysplastic syndrome. The methods involve maintaining the activity of GATA-1 by preventing sequestration of Hsp70 in the cytoplasm. Accordingly, it is an object of this invention to provide methods of restoring or increasing erythrocyte maturation in a subject suffering from a myelodysplastic syndrome by preventing proteolytic inactivation of GATA-1. In some embodiments, preventing is achieved by administering to the subject a compound that inhibits the XPO1 nuclear transporter.Type: GrantFiled: June 9, 2015Date of Patent: June 13, 2017Assignees: Institut National de la Sante et de la Recherche Medicale (INSERM), Fondation Imagine, Assistance Publique-Hopitaux de Paris (APHP), Universite Paris Descartes, Centre National de la Recherche Scientifique (CNRS)Inventors: Olivier Hermine, Flavia Guillem, Jean-Benoit Arlet, Genevève Courtois, Michaela Fontenay
