The process of authoring ontologies requires the active involvement of domain experts who should lead the process, as well as providing the relevant conceptual knowledge. However, most domain experts lack knowledge modelling skills and find it hard to follow logical notations in OWL. This paper presents ROO, a tool that facilitates domain experts'(More)
Myotonic dystrophy type 1 (DM1) is associated with one of the most highly unstable CTG*CAG repeat expansions. The formation of further repeat expansions in transgenic mice carrying expanded CTG*CAG tracts requires the mismatch repair (MMR) proteins MSH2 and MSH3, forming the MutSbeta complex. It has been proposed that binding of MutSbeta to CAG hairpins(More)
The genetic basis of myotonic dystrophy type I (DM1) is the expansion of a CTG tract located in the 3' untranslated region of DMPK. Expression of mutant RNAs encoding expanded CUG repeats plays a central role in the development of cardiac disease in DM1. Expanded CUG tracts form both nuclear and cytoplasmic aggregates, yet the relative significance of such(More)
Myotonic dystrophy (DM) is a multi-system neuromuscular disorder for which there is no treatment. We have developed a medium throughput phenotypic assay, based on the identification of nuclear foci in DM patient cell lines using in situ hybridization and high-content imaging to screen for potentially useful therapeutic compounds. A series of further assays(More)
Nesprin-1-giant and nesprin-2-giant regulate nuclear positioning by the interaction of their C-terminal KASH domains with nuclear membrane SUN proteins and their N-terminal calponin-homology domains with cytoskeletal actin. A number of short isoforms lacking the actin-binding domains are produced by internal promotion. We have evaluated the significance of(More)
Severe forms of myotubular myopathy (MTM) and congenital myotonic dystrophy type 1 (CDM), both present as floppy infants with hypotonia, respiratory failure and bulbar insufficiency. Muscle biopsy is often performed as part of the diagnostic process, but these two disorders share very similar histopathological features. It is well documented that CDM muscle(More)
Mutations in the mismatch repair gene MSH2 underlie hereditary nonpolyposis colorectal cancer (Lynch syndrome). Whereas disruptive mutations are overtly pathogenic, the implications of missense mutations found in sporadic colorectal cancer patients or in suspected Lynch syndrome families are often unknown. Adequate genetic counseling of mutation carriers(More)
This demonstration will present the first stage of the ROO tool, a Protégé plugin that facilitates domain experts with little or no knowledge engineering experience to build ontologies. The ontology authoring process is assisted by offering task-driven suggestions and appropriate help, based on an ontology construction methodology developed at Ordnance(More)
Five subtypes of dopamine receptor exist in two subfamilies: two D(1)-like (D(1) and D(5)) and three D(2)-like (D(2), D(3) and D(4)). We produced novel monoclonal antibodies against all three D(2)-like receptors and used them to localize receptors in Ntera-2 (NT-2) cells, the human neuronal precursor cell line. Most of the immunostaining for all three(More)
