Transcription factors are key components of regulatory networks that control development, as well as the response to environmental stimuli. We have established an experimental pipeline in Caenorhabditis elegans that permits global identification of the binding sites for transcription factors using chromatin immunoprecipitation and deep sequencing. We(More)
Measurements of neuron-specific and glia-specific proteins were used to characterize chemical-induced injury to the rat CNS. Trimethyltin (TMT), a neurotoxicant that preferentially damages neurons in limbic structures, was employed to produce consistent, time-dependent, dose-related, cell type-specific alterations in CNS morphology. Brain weights and(More)
Abnormalities were detected by two-dimensional gel electrophoresis in the protein composition of both the dorsal and ventral roots of three of six patients who succumbed to amyotrophic lateral sclerosis (ALS). The abnormalities consisted of a cascade of acidic protein spots on silver-stained gels which were shown by immunoblotting to react with an antiserum(More)
The C. difficile infection rate in South Africa is concerning. Many strains previously isolated from diarrhetic patients at Groote Schuur Hospital were ribotype 017. This study further characterised these strains with respect to their clonal relationships, antibiotic susceptibility, toxin production and various attributes impacting on pathogen colonisation.(More)
The suitability of using spinal tissue several hours after death for analysis by high resolution two-dimensional electrophoresis has been examined. It was found that many of the proteins of bovine spinal motoneurons detectable on two-dimensional polyacrylamide gels appear to be relatively stable in situ at room temperature during the first postmortem day.(More)
