Leigh syndrome due to compound heterozygosity of dihydrolipoamide dehydrogenase gene mutations. Description of the first E3 splice site mutation.

2003

Item does not contain fulltext A boy with recurrent episodes of hypoglycaemia and ataxia, microcephaly, mental retardation, permanent lactic acidaemia, intermittent 2-oxoglutaric aciduria as well as elevation of serum branched chain amino acids was diagnosed with dihydrolipoamide dehydrogenase (E3) deficiency. Analysis of genomic DNA revealed compound heterozygosity for two novel mutations: I393T in exon 11, located at the interface domain of the protein and possibly interfering with its dimerisation, and IVS9+1G>A located at a consensus splice site. A heterozygous polymorphism was also detected. In the patient's cDNA the I393T mutation and the polymorphism appeared to be homozygous, indica…

Mildronate, a Regulator of Energy Metabolism, Reduces Atherosclerosis in apoE/LDLR<sup>–/–</sup> Mice

2009

<i>Background/Aims:</i> Mildronate, an inhibitor of <i>L</i>-carnitine biosynthesis and transport, is used in clinics as a modulator of cellular energy metabolism and is a cardioprotective drug. <i>L</i>-Carnitine is a pivotal molecule in fatty acid oxidation pathways and its regulation in vasculature might be a promising approach for antiatherosclerotic treatment. This study was performed to evaluate the effects of mildronate treatment on the progression of atherosclerosis and the content of <i>L</i>-carnitine in the vascular wall. <i>Methods:</i> ApoE/LDLR<sup>–/–</sup> mice received mildronate at doses of 30 and 100 …

MPP1 links the Usher protein network and the Crumbs protein complex in the retina.

2007

Contains fulltext : 53571.pdf (Publisher’s version ) (Closed access) The highly ordered distribution of neurons is an essential feature of a functional mammalian retina. Disruptions in the apico-basal polarity complexes at the outer limiting membrane (OLM) of the retina are associated with retinal patterning defects in vertebrates. We have analyzed the binding repertoire of MPP5/Pals1, a key member of the apico-basal Crumbs polarity complex, that has functionally conserved counterparts in zebrafish (nagie oko) and Drosophila (Stardust). We show that MPP5 interacts with its MAGUK family member MPP1/p55 at the OLM. Mechanistically, this interaction involves heterodimerization of both MAGUK mo…

Development of the first marmoset-specific DNA microarray (EUMAMA): a new genetic tool for large-scale expression profiling in a non-human primate

2007

Abstract Background The common marmoset monkey (Callithrix jacchus), a small non-endangered New World primate native to eastern Brazil, is becoming increasingly used as a non-human primate model in biomedical research, drug development and safety assessment. In contrast to the growing interest for the marmoset as an animal model, the molecular tools for genetic analysis are extremely limited. Results Here we report the development of the first marmoset-specific oligonucleotide microarray (EUMAMA) containing probe sets targeting 1541 different marmoset transcripts expressed in hippocampus. These 1541 transcripts represent a wide variety of different functional gene classes. Hybridisation of …
