Autosomal dominant optic atrophy (ADOA) is the most prevalent hereditary optic neuropathy resulting in progressive loss of visual acuity, centrocoecal scotoma and bilateral temporal atrophy of the optic nerve with an onset within the first two decades of life. The predominant locus for this disorder (OPA1; MIM 165500) has been mapped to a 1.4-cM interval on(More)
PURPOSE Array comparative genomic hybridization is rapidly becoming an integral part of cytogenetic diagnostics. We report the design, validation, and clinical utility of an oligonucleotide array which combines genome-wide coverage with targeted enhancement at known clinically relevant regions. METHODS Probes were placed every 75 kb across the entire(More)
A systematic investigation into the effect of surface chemistry on bacterial adhesion was carried out. In particular, a number of physicochemical factors important in defining the surface at the molecular level were assessed for their effect on the adhesion of Listeria monocytogenes, Salmonella typhimurium, Staphylococcus aureus, and Escherichia coli. The(More)
We and others have shown recently that mutations in the OPA1 gene encoding a dynamin-related mitochondrial protein cause autosomal dominant optic atrophy (ADOA) linked to chromosome 3q28-q29. Here we report screening of the OPA1 gene in a sample of 78 independent ADOA families. OPA1 mutations were identified in 25 patients (detection rate 32.1%) including(More)
In order to further use the spinocerebellar ataxia 2 (SCA2) promoter for transgenic mice models of "CAG repeat" neurodegeneration, different fragments of this 5' end were ligated into pGL3-Luc plasmid to obtain the better promoter-activity of the physiological promoter for SCA2. Base-par composition of the SCA2-5' region, and promoter prediction algorithms(More)
Dominant optic atrophy (DOA) is a hereditary optic neuropathy characterised by decreased visual acuity, colour vision deficits, centro-coecal scotoma and optic nerve pallor. The gene OPA1, encoding a dynamin-related GTPase, has recently been identified within the genetic linkage interval for the major locus for DOA on chromosome 3q28 and shown to harbour(More)
EMT6 multicellular spheroids invariably swell by 10 to 50 per cent after incubation at 43 to 45 degrees C for 1 h. Both scanning electron and optical microscopy reveal morphological alterations particularly in the outer region of the spheroids. While the control cells are contiguous to one another and tightly held to the spheroid body, the heated spheroids(More)
We have fine mapped 29 ESTs of Genemap'99 to YACs and radiation hybrids covering 8 cM of the chromosomal region of 3q28-q29. Focusing on the genetic interval of approximately 1 Mb between markers D3S3669 and D3S3562 we established a sequence-ready PAC contig which covers the OPA1 locus containing the gene causing autosomal dominant optic atrophy (ADOA;(More)
