Induction of Id1 and Id3 by latent membrane protein 1 of Epstein-Barr virus and regulation of p27/Kip and cyclin-dependent kinase 2 in rodent fibroblast transformation.

Latent membrane protein 1 (LMP1), the Epstein-Barr virus oncoprotein, activates NF-kappaB, phosphatidylinositol 3-kinase, mitogen-activated protein kinase, and c-Jun N-terminal kinase signaling. To determine global transcriptional changes induced by LMP1 in epithelial cells, genomic analysis of C33A cells stably expressing LMP1 was performed. Relatively few genes were induced by LMP1. Expression ... More
Effects of rottlerin on silica-exacerbated systemic autoimmune disease in New Zealand mixed mice.

PubMed ID16040631
'Environmental crystalline silica exposure has been associated with formation of autoantibodies and development of systemic autoimmune disease, but the mechanisms leading to these events are unknown. Silica exposure in autoimmune-prone New Zealand mixed (NZM) mice results in a significant exacerbation of systemic autoimmunity as measured by increases in autoantibodies and ... More
Development of microarray and multiplex polymerase chain reaction assays for identification of serovars and virulence genes in Salmonella enterica of human or animal origin.
'Salmonella enterica is an important enteric pathogen consisting of many serovars that can cause severe clinical diseases in animals and humans. Rapid identification of Salmonella isolates is especially important for epidemiologic monitoring and controlling outbreaks of disease. Although immunologic and DNA-based serovar identification methods are available for rapid identification of ... More
Specific discrimination of three pathogenic Salmonella enterica subsp. enterica serotypes by carB-based oligonucleotide microarray.

PubMed ID24185846
'It is important to rapidly and selectively detect and analyze pathogenic Salmonella enterica subsp. enterica in contaminated food to reduce the morbidity and mortality of Salmonella infection and to guarantee food safety. In the present work, we developed an oligonucleotide microarray containing duplicate specific capture probes based on the carB ... More
Multiplex detection of RNA expression in Drosophila embryos.

JournalScience
PubMed ID15297669
We present a fluorescence-based, multiplex in situ hybridization method that permits the simultaneous detection of five differently labeled antisense RNA probes and up to seven differ-ent transcripts in a single Drosophila embryo. We also show that it should be possible to increase the number of detected transcripts substantially with nascent ... More
Defects in lamin B1 expression or processing affect interphase chromosome position and gene expression.
AuthorsMalhas A, Lee CF, Sanders R, Saunders NJ, Vaux DJ,
JournalJ Cell Biol
PubMed ID17312019
Radial organization of nuclei with peripheral gene-poor chromosomes and central gene-rich chromosomes is common and could depend on the nuclear boundary as a scaffold or position marker. To test this, we studied the role of the ubiquitous nuclear envelope (NE) component lamin B1 in NE stability, chromosome territory position, and ... More
Comparison of detection and signal amplification methods for DNA microarrays.
AuthorsVora GJ, Meador CE, Anderson GP, Taitt CR,
JournalMol Cell Probes
PubMed ID18675897
One of the factors limiting the use of DNA microarray technology for the detection of pathogenic organisms from clinical and environmental matrices has been inadequate assay sensitivity. To assess the effectiveness of post-hybridization secondary detection steps to enhance the sensitivity of DNA microarray-based pathogen detection, we evaluated a panel of ... More
Borrelia burgdorferi sigma54 is required for mammalian infection and vector transmission but not for tick colonization.

PubMed ID15743918
Previous studies have shown that a sigma54-sigma(S) cascade regulates the expression of a few key lipoproteins in Borrelia burgdorferi, the agent of Lyme disease. Here, we demonstrate that these sigma factors, both together and independently, regulate a much more extensive number of genes and cellular processes. Microarray analyses of sigma54 ... More
Cold shock of a hyperthermophilic archaeon: Pyrococcus furiosus exhibits multiple responses to a suboptimal growth temperature with a key role for membrane-bound glycoproteins.
The hyperthermophilic archaeon, Pyrococcus furiosus, was grown on maltose near its optimal growth temperature, 95 degrees C, and at the lower end of the temperature range for significant growth, 72 degrees C. In addition, cultures were shocked by rapidly dropping the temperature from 95 to 72 degrees C. This resulted ... More
