H-NS silences gfp, the Green Fluorescent Protein gene: gfpTCD is a genetically remastered gfp gene with reduced susceptibility to H-NS-mediated transcription silencing and with enhanced translation
(2010)The bacterial nucleoid-associated protein H-NS, which preferentially targets and silences A+T-rich genes, binds the ubiquitous reporter gene gfp and dramatically reduces local transcription. We have redesigned gfp to reduce ... -
H2B ubiquitylation is part of chromatin architecture that marks exon-intron structure in budding yeast
(2011)Background The packaging of DNA into chromatin regulates transcription from initiation through 3' end processing. One aspect of transcription in which chromatin plays a poorly understood role is the co-transcriptional ... -
Helicobacter pylori infection : in vitro diagnostic methods, antimicrobial susceptibility testing, epidemiology of recrudescence and clarithromycin resistance
(Trinity College (Dublin, Ireland). Department of Microbiology, 2000)H. pylori is a Gram-negative, non-spore forming, curved bacterium that colonises the gastric epithelium of the human stomach. H. pylori is firmly established as an aetiological agent in peptic ulcer disease and successful ... -
High-throughput investigation of virulence gene regulation by sRNAs in Salmonella Typhimurium
(Trinity College (Dublin, Ireland). Department of Microbiology, 2015)This study focused on novel gene regulatory systems in Salmonella enterics serovar Typhimurium, a model gram-negative, bacterial pathogen. The sRNA-mediated control of virulence genes was a particular emphasis. The research ... -
The hybrid genomes of Saccharomyces pastorianus-a current perspective
(2018)Saccharomyces pastorianus is a recently evolved interspecies hybrid of Saccharomyces cerevisiae and Saccharomyces eubayanus used in the production of lager-type beers and has a long-standing history with the brewing industry. ... -
Identification and characterisation of an FK506-binding protein from Plasmodium falciparum
(Trinity College (Dublin, Ireland). Department of Microbiology, 2004)Malaria remains one of the most significant diseases worldwide. The most common and severe form of the disease is caused by Plasmodium falciparum. The need for new anti-malarial compounds has intensified in recent years ... -
Identification and characterization of novel Plasmodium falciparum cyclophilins and their roles in the antimalarial actions of cyclosporin A
(Trinity College (Dublin, Ireland). Department of Microbiology, 2011)Malaria is a parasitic infection of immense global importance. The most common and severe form of the disease is caused by the blood-borne apicomplexan Plasmodium falcipanim. The lack of an effective vaccine coupled with ... -
Identification and characterization of novel Plasmodium falciparum cyclophilins and their roles in the antimalarial actions of cyclosporin A and derivatives
(BioMed Central, 2010)Cyclophilins are distributed widely among different organisms and are proposed drug targets for a number of diseases including HIV and hepatitis C infection and ischemia. Cyclophilins play roles in folding and chaperoning ... -
Identification of factors involved in 3' end processing and transcription termination of histone mRNAs
(Trinity College (Dublin, Ireland). Department of Microbiology, 2011)The production of core histone mRNAs is tightly regulated during the cell cycle in all eukaryotic cells. Histone mRNAs accumulate during the S-phase and are subsequently degraded upon entry into G2-phase of the cell cycle. ... -
Identification of the merR gene of R100 by using mer-lac gene and operon fusions
(1985)Transcriptional (operon) and translational (gene) fusions between the R100 merR gene and lacZ were constructed in vitro in a pBR322 plasmid carrying the mer genes derived from plasmid R100. The translational fusions were ... -
IL-33 and IL-18 in inflammatory bowel disease etiology and microbial interactions
(2019)The IL-1 cytokines are a newly expanded family, with each of its 11 members playing an important role in health and disease. Typically acting as pro- or anti-inflammatory mediators of first-line innate immunity, their ... -
The immune evasion protein Sbi of Staphylococcus aureus occurs both extracellularly and anchored to the cell envelope by binding lipoteichoic acid
(2012)The Sbi protein of Staphylococcus aureus comprises two IgG binding domains similar to those of protein A and a region that triggers the activation of complement C3. Sbi is expressed on the cell surface but its C-terminal ... -
Immune responses to cereal prolamin proteins in coeliac disease
(Trinity College (Dublin, Ireland). Department of Microbiology, 2004)Coeliac disease is an inflammatory disease of the small intestine, precipitated in susceptible individuals by gliadin, the alcohol soluble (prolamin) fraction of wheat gluten. There is a strong genetic influence on ... -
Immunophilin-protein interactions in Plasmodium falciparum.
(2015)Immunophilins comprise two protein families, cyclophilins (CYPs) and FK506-binding proteins (FKBPs), and are the major receptors for the immunosuppressive drugs cyclosporin A (CsA) and FK506 (tacrolimus), respectively. ... -
Impact of Metabolites on the Intestinal Mucosa and Development of Inflammation
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2021)The intestinal epithelial mucosal barrier plays a pivotal role in the maintenance of intestinal homeostasis, acting as an important barrier between microbes and the host s innate immune system. The metabolite-rich environment ...
