Activation of the PhoPR-mediated response to phosphate limitation is regulated by wall teichoic acid metabolism in Bacillus subtilis
(2018)Phosphorous is essential for cell viability. To ensure an adequate supply under phosphate limiting conditions, bacteria induce a cohort of enzymes to scavenge for phosphate, and a high affinity transporter for its uptake ... -
Adhesion, invasion and evasion: the many functions of the surface proteins of Staphylococcus aureus
(2014)Staphylococcus aureus is an important opportunistic pathogen and persistently colonizes about 20% of the human population. Its surface is 'decorated' with proteins that are covalently anchored to the cell wall peptidoglycan. ... -
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 ... -
Analysis of stage-specific gene perturbations and characterisation of two novel F-box genes during flower development in Arabidopsis thaliana
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2018)The model plant Arabidopsis thaliana has been used for past three decades to study the genetic and molecular processes underlying floral organogenesis. Flowers of this small plant consist of four concentric whorls, containing ... -
Antimitotic herbicides bind to an unidentifed site on malarial parasite tubulin and block development of liver-stage Plasmodium parasites.
(2013)Malarial parasites are exquisitely susceptible to a number of microtubule inhibitors but most of these compounds also affect human microtubules. Herbicides of the dinitroaniline and phosphorothioamidate classes however ... -
Autophagy in Multiple Myeloma: What Makes You Stronger Can Also Kill You.
(2013)Autophagy, a process for recycling cellular constituents, is normally associated with cell survival and is thought to be beneficial for tumor maintenance. However, in this issue of Cancer Cell, Lamy and colleagues report ... -
Autosis: A new addition to the cell death tower of babel
(2014)Autophagy is a cellular recycling and stress response that degrades organelles and long-lived proteins and serves to protect cells from the potential damage induced by dysfunc- tional organelles and protein aggregates. ... -
Bacterial DNA topology and infectious disease
(2009)he gram-negative bacterium Escherichia coli and its close relative Salmonella enterica have made important contributions historically to our understanding of how bacteria control DNA supercoiling and of how supercoiling ... -
Bacterial L-forms on tap: an improved methodology to generate Bacillus subtilis L-forms heralds a new era of research
(2012)Bacterial L-forms are cell wall-less forms of bacteria that usually grow with a conventional cell wall. Despite being important for research, L-forms are difficult to generate reproducibly and research in this area is ... -
Bacterial regulon evolution: distinct responses and roles for the identical OmpR proteins of Salmonella Typhimurium and Escherichia coli in the acid stress response
(2014)The evolution of new gene networks is a primary source of genetic innovation that allows bacteria to explore and exploit new niches, including pathogenic interactions with host organisms. For example, the archetypal DNA ... -
The blood-brain barrier in neuropsychiatric disorders
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2018)Schizophrenia is a severe and disabling mental disorder that affects approximately 1% of the population. Such is the heterogeneous nature of the disease that genetic, neurobiological and environmental factors all contribute ... -
The blood-retina barrier in health and disease
(2021)The blood–retina barrier (BRB) is the term used to define the properties ofthe retinal capillaries and the retinal pigment epithelium (RPE), which sep-arate the systemic circulation from the retina. More specifically, the ... -
Boundary cap cells constrain spinal motor neuron somal migration at motor exit points by a semaphorin-plexin mechanism
(2007)Background: In developing neurons, somal migration and initiation of axon outgrowth often occur simultaneously and are regulated in part by similar classes of molecules. When neurons reach their final destinations, however, ... -
Broad scale redistribution of mRNA abundance and transcriptional machinery in response to growth rate in Salmonella enterica serovar Typhimurium
(2017)We have investigated the connection between the four-dimensional architecture of the bacterial nucleoid and the organism's global gene expression programme. By localizing the transcription machinery and the transcriptional ... -
Caspase-1 promiscuity is counterbalanced by rapid inactivation of the processed enzyme.
(2011)Members of the caspase family of cysteine proteases coordinate the highly disparate processes of apoptosis and inflammation. However, while hundreds of substrates for the apoptosis effector caspases (caspase-3 and caspase-7) ... -
Cell envelope gene expression in phosphate-limited Bacillus subtilis cells.
(2011)The high phosphate content of Bacillus subtilis cell walls dictates that cell wall metabolism is an important feature of the PhoPR-mediated phosphate limitation response. Here we report the expression profiles of ... -
Characterising the effects of sex interaction, pleiotropy and local population structure on ALS GWAS
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2021)In the past decade, increasingly large-scale genome wide association studies (GWAS) have gleaned insights into the genetic architecture of a range of human traits. Widespread sharing of summary statistics for these GWAS ... -
CHD5 is required for neurogenesis and has a dual role in facilitating gene expression and polycomb gene repression
(2013)The chromatin remodeler CHD5 is expressed in neu- ral tissue and is frequently deleted in aggressive neuroblastoma.Verylittleisknownaboutthefunction of CHD5 in the nervous system or its mechanism of action. Here we ...
