Intrathecal delivery of recombinant human iduronate-2-sulfatase (idursulfase-IT)
Molecular Genetics and Metabolism, 2011Background: Idursulfase has limited passage through the bloodbrain barrier when administered intravenously. Objectives: We have undertaken a program to develop an intrathecal (IT) formulation of idursulfase to target CNS manifestations of MPS II. Methods: In a safety study, single bolus injections of idursulfase-IT 3 mg (n=12), 30 mg (n=6), or 100 mg ...

A novel functional role of iduronate-2-sulfatase in zebrafish early development
Matrix Biology, 2010Sulfated glycosaminoglycan chains of extracellular matrix and cell membrane-tethered proteoglycans exert specific cellular functions by interacting with a broad spectrum of morphogens and growth factors. In humans, a congenital impaired catabolism of sulfated glycosaminoglycans is associated with severe metabolic disorders.

Genetic Engineering of a Bifunctional IgG Fusion Protein with Iduronate-2-Sulfatase
Bioconjugate Chemistry, 2009Iduronate-2-sulfatase (IDS) is a lysosomal sulfatase that prevents the accumulation within the brain of glycosoaminoglycans. However, IDS does not cross the blood-brain barrier (BBB). To enable BBB transport, human IDS, minus its signal peptide, was fused to the carboxyl terminus of the heavy chain of a chimeric monoclonal antibody (mAb) to the human ...

DNA deletion confined to the iduronate-2-sulfatase promoter abolishes IDS gene expression
Human Mutation, 1998Deficiency of the enzyme iduronate-2-sulfatase (IDS) results in Hunter syndrome, an X-linked recessive lysosomal storage disorder. In this study, analysis of a patient with features of moderate to severe Hunter syndrome identified a 178-bp deletion upstream of IDS exon 1 spanning a predicted promoter element.

Production of therapeutic iduronate‐2‐sulfatase enzyme with a novel single‐stranded RNA virus vector
Genes to Cells, 2021AbstractThe Sendai virus vector has received a lot of attention due to its broad tropism for mammalian cells. As a result of efforts for genetic studies based on a mutant virus, we can now express more than 10 genes of up to 13.5 kilo nucleotides in a single vector with high protein expression efficiency. To prove this benefit, we examined the efficacy

Expression of the two iduronate-2-sulfatase cDNAs.
Biochemistry and molecular biology international, 1995The iduronate-2-sulfatase (IDS) is a lysosomal enzyme that acts on sulphate groups on C-2 positions of the iduronic acid residues of the mucopolysaccharides heparan sulphate and dermatan sulphate. Recently, we described in mouse two IDS mRNAs: the first or canonic (MTA16), highly homologous to the human counterpart, the second or novel (MTA13 ...

Molecular investigations of a novel iduronate-2-sulfatase mutant in a Chinese patient
Clinica Chimica Acta, 2008Molecular investigations of iduronate-2-sulfatase (IDS) mutants for the X-linked lysosomal storage disease mucopolysaccharidosis type II (MPS II, Hunter disease), commonly depends on transient expression studies to verify a single nucleotide change to be pathogenic.

Eight unrelated patients with Hunter syndrome were investigated for expression of iduronate-2-sulfatase (IDS) mRNA by reverse transcription (RT) linked to polymerase chain reaction (PCR), or RT-PCR. The entire coding region was studied by amplification of two overlapping segments of 0.7 and 1.1 kb.

Mutations in the iduronate-2-sulfatase gene in five Norwegians with Hunter syndrome
Human Genetics, 1996We have identified the mutations in the iduronate-2-sulfatase (IDS) gene of five unrelated Norwegians with Hunter syndrome by reverse transcription-polymerase chain reaction (RT-PCR) analysis of IDS mRNA followed by single strand conformation polymorphism (SSCP) analysis and cDNA sequencing. One patient had a 5-bp deletion, located at the intron 5/exon

A novel iduronate 2-sulfatase mutation in a Chinese family with mucopolysaccharidosis type II
World Journal of Pediatrics, 2012Mucopolysaccharidosis type II (MPS II; also known as Hunter syndrome) is an X-linked multisystem disorder resulting from the defective activity of the enzyme iduronate-2-sulfatase (IDS). Genetic testing is crucial in clarifying and diagnosing different types of MPS diseases.
