Genome architecture and global transcriptional control in bacteria: making progress towards a unified model?
(2013)Data obtained with advanced imaging techniques, chromosome conformation capture methods, bioinformatics and molecular genetics, together with insights from polymer physics and mechanobiology, are helping to refine our ... -
Co-operative roles for DNA supercoiling and nucleoid-associated proteins in the regulation of bacterial transcription
(2013)DNA supercoiling and NAPs (nucleoid-associated proteins) contribute to the regulation of transcription of many bacterial genes. The horizontally acquired SPI (Salmonella pathogenicity island) genes respond positively to ... -
Molecular Characterization of the Multiple Interactions of SpsD, a Surface Protein from Staphylococcus pseudintermedius, with Host Extracellular Matrix Proteins
(2013)Staphylococcus pseudintermedius, a commensal and pathogen of dogs and occasionally of humans, expresses surface proteins potentially involved in host colonization and pathogenesis. Here, we describe the cloning and ... -
Emergence of the Epidemic Methicillin-Resistant Staphylococcus aureus Strain USA300 Coincides with Horizontal Transfer of the Arginine Catabolic Mobile Element and speG-mediated Adaptations for Survival on Skin.
(2013)The arginine catabolic mobile element (ACME) is the largest genomic region distinguishing epidemic USA300 strains of methicillin-resistant Staphylococcus aureus (MRSA) from other S. aureus strains. However, the functional ... -
Subdomains N2N3 of Fibronectin Binding Protein A Mediate Staphylococcus aureus Biofilm Formation and Adherence to Fibrinogen Using Distinct Mechanisms.
(2013)Health care-associated methicillin-resistant Staphylococcus aureus (HA-MRSA) forms biofilm in vitro that is dependent on the surface-located fibronectin binding proteins A and B (FnBPA, FnBPB). Here we provide new insights ... -
Complement regulator C4BP binds to Staphylococcus aureus surface proteins SdrE and Bbp inhibiting bacterial opsonization and killing.
(2013)Staphylococcus aureus is a premier human pathogen and the most common cause of osteoarticular, wound, and implanted device infections. We recently demonstrated S. aureus efficiently binds the classical complement regulator ... -
Targeted nasal vaccination provides antibody independent protection against Staphylococcus aureus.
(2013)Despite showing promise in preclinical models, anti–Staphylococcus aureus vaccines have failed in clinical trials. To date, approaches have focused on neutralizing/opsonizing antibodies; however, vaccines exclusively ... -
Antimalarial drug discovery and design in the Era of resistance
(2013)These are interesting times for antimalarial drug research. On the one hand, recent reports from Southeast Asia paint a grim picture of reduced malarial parasite susceptibility to artemisinin combination therapies ... -
Anti-disease therapy for malaria: 'resistance proof'?
(2013)Antimalarial drugs have in the past fallen prey to resistance and this problem is likely to continue in the future. One approach to developing drugs that might be less prone to resistance might be to target the disease ... -
Simply red: A novel spectrophotometric erythroid proliferation assay as a tool for erythropoiesis and erythrotoxicity studies
(2014)Most mammalian cell proliferation assays rely on manual or automated cell counting or the assessment of metabolic activity in colorimetric assays, with the former being either labor and time intensive or expensive and the ... -
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 ... -
VirB-mediated positive feedback control of the virulence gene regulatory cascade of Shigella flexneri
(2012)Shigella flexneri is a facultative intracellular pathogen that relies on a type III secretion system and its associated effector proteins to cause bacillary dysentery in humans. The genes that encode this virulence system ... -
The transcriptional landscape and small RNAs of Salmonella enterica serovar Typhimurium
(2012)More than 50 y of research have provided great insight into the physiology, metabolism, and molecular biology of Salmonella enterica serovar Typhimurium (S. Typhimurium), but important gaps in our knowledge remain. It is ... -
A fundamental regulatory mechanism operating through OmpR and DNA topology controls expression of Salmonella pathogenicity islands SPI-1 and SPI-2
(2012)DNA topology has fundamental control over the ability of transcription factors to access their target DNA sites at gene promoters. However, the influence of DNA topology on protein–DNA and protein–protein interactions is ... -
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 ... -
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 ...
