A bioinformatics approach to (intra-) genome comparisons
(Trinity College (Dublin, Ireland). School of Genetics and Microbiology, 2002)The analysis of large volumes of genomic data generates special computational needs. A Beowulf-type computer cluster was set up for high-performance computing. Improvements over existing tools for the efficient ... -
A leaf-specific phage T7 RNA polymerase-based system for transgene expression in tobacco chloroplasts
(Trinity College (Dublin, Ireland). School of Genetics and Microbiology, 2001)This thesis describes the development of a chloroplast-localised gene expression system based on the phage T7 RNA polymerase. In order to direct T7 RNAP expression in a leaf-specific manner and to target it to the ... -
A molecular genetic investigation of Irish origins
(Trinity College (Dublin, Ireland). Department of Genetics, 2000)Three hundred and ninety-four male DNA samples, from Ireland, Turkey and Togo, were genotyped for 5 X chromosome simple tandem repeat (STR) loci. Six Y chromosome STR loci and 8 Y chromosome unique event polymorphisms were ... -
A study of the expression and roles of Bacillus subtilis HtrA-type serine proteases
(Trinity College (Dublin, Ireland). Department of Genetics, 2003)Upon sequencing a region of the Bacillus subtilis genome assigned to the author of this thesis, an open reading frame encoding a homologue of an HtrA-type serine protease, YkdA, was identified. The HtrA serine protease ... -
Accurate Determination of Phenotypic Information from Historic Thoroughbred Horses by Single Base Extension
(PLoS, 2010)Historic DNA data have the potential to identify phenotypic information otherwise invisible in the historical, archaeological and palaeontological record. In order to determine whether a single nucleotide polymorphism ... -
The Adam family metalloprotease Kuzbanian regulates the cleavage of the roundabout receptor to control axon repulsion at the midline.
(2010)Slits and their Roundabout (Robo) receptors mediate repulsive axon guidance at the Drosophila ventral midline and in the vertebrate spinal cord. Slit is cleaved to produce fragments with distinct signaling properties. In ... -
Additions, losses, and rearrangements on the evolutionary route from a reconstructed ancestor to the modern Saccharomyces cerevisiae genome.
(PLoS, 2009)Comparative genomics can be used to infer the history of genomic rearrangements that occurred during the evolution of a species. We used the principle of parsimony, applied to aligned synteny blocks from 11 yeast species, ... -
Adhesion and invasion by Escherichia coli K1
(Trinity College (Dublin, Ireland). Department of Microbiology, 2006)Escherichia coli is one of the principal causes of septicaemia and meningitis in neonates. Sepsis occurs in approximately one in every thousand live births, with up to 10% progressing to develop meningitis. A disproportionate ... -
Altered retinal microRNA expression profile in a mouse model of retinitis pigmentosa.
(BioMed Central, 2007)Background The role played by microRNAs (miRs) as common regulators in physiologic processes such as development and various disease states was recently highlighted. Retinitis pigmentosa (RP) linked to RHO (which encodes ... -
Altered ribostasis: RNA-protein granules in degenerative disorders
(2013)The molecular processes that contribute to degenerative diseases are not well understood. Recent observations suggest that some degenerative diseases are promoted by the accumulation of nuclear or cytoplasmic RNA-protein ... -
Alternative routes to optimal expression levels: Evolutionary evidence for competitive RNAs and dosage compensation by gene duplication
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2019)Expression evolution and dosage constraints are important factors shaping genomic content and innovation. It has become increasingly clear that non-coding RNAs perform various regulatory functions in different cellular ... -
Amino acid identity at one position within the alpha1 helix of both the histidine kinase and the response regulator of the WalRK and PhoPR two-component systems plays a crucial role in the specificity of phosphotransfer.
(2010)Two-component systems usually function as cognate pairs, thereby ensuring an appropriate response to the detected signal. The ability to exclusively phosphorylate a partner protein, often in the presence of many competing ... -
An examination of Serotonergic candidate genes in Attention Deficit Hyperactivity Disorder
(Trinity College (Dublin, Ireland). Department of Genetics, 2008)Attention Deficit Hyperactivity Disorder (ADHD) is a common, highly heritable childhood disorder. It is characterised by symptoms of inattention, hyperactivity, and impulsivity. Heritability of ADHD is estimated to be ... -
An investigation into the complex genetics of bipolar affective disorder : potential susceptibility loci and candidate genes from the Irish population
(Trinity College (Dublin, Ireland). Department of Genetics, 2008)Bipolar affective disorder (BPAD) is a serious and debilitating psychiatric illness characterised by extreme changes in mood, ranging from depression to mania. BPAD is undoubtedly caused by genetic factors, with some ... -
An investigation of the role of caspase-9-interacting proteins in the molecular control of apoptosis
(Trinity College (Dublin, Ireland). Department of Genetics, 2001)Apoptosis is an important homeostatic mechanism that multicellular organisms utilize to delete cells during development and on an ongoing basis in the adult. At the molecular level, this requires the activation of a family ... -
Analysis of gene evolution and metabolic pathways using the Candida Gene Order Browser.
(BioMed Central, 2010)Background: Candida species are the most common cause of opportunistic fungal infection worldwide. Recent sequencing efforts have provided a wealth of Candida genomic data. We have developed the Candida Gene Order Browser ...
