Gene expression changes in Porphyromonas gingivalis W83 after inoculation in rat oral cavity

(Submitter supplied) The aim of this study is to investigate the alterations in gene expression in Porphyromonas gingivalis W83 after inoculation in rat oral cavity. P.gingivalis W83 inoculation in rat oral cavity caused inflammatory responses in gingival tissues and destroyed host alveolar bone. Microarray analysis revealed that 42 genes were upregulated, and 22 genes were downregulated in the detected 1786 genes in the inoculated P.gingivalis W83. more...

Porphyromonas gingivalis 33277 wild-type vs Fur orthologue Har isogenic mutant ECR455

(Submitter supplied) Porphyromonas gingivalis is a major pathogen associated with the microbial biofilm-mediated disease chronic periodontitis. P. gingivalis has an obligate requirement for iron and protoporphyrin IX which it satisfies by transporting heme and iron liberated from the human host. The level of cellular iron in P. gingivalis affects the expression of a distinct iron-associated regulon of 64 genes and low iron invokes an iron sparing response. more...

Polyphosphate affects gene expression and viability of Porphyromonas gingivalis W83

(Submitter supplied) Polyphosphate (polyP) is a ubiquitous and abundant compound found in bacteria, fungi, algae, plant, and animals. Among roles of intracellular polyP in bacteria are resistance and survival in the stationary phase of the growth against stress and stringent condition. Therefore, intracellular polyP is considered as a virulence factor of bacteria. In contrast, exogenous polyP has an antimicrobial activity against a variety of microorganisms. more...

Porphyromonas gingivalis comparative genomic hybridization

(Submitter supplied) Genotyping studies suggest that there is genetic variability among P. gingivalis strains, however the extent of variability remains unclear, and the regions of variability have only partially been identified. We previously used heteroduplex analysis of the ribosomal operon intergenic spacer region (ISR) to type P. gingivalis strains in several diverse populations, identifying 6 predominant heteroduplex types and many minor ones. more...

Expression data from human macrophages treated with Porphyromonas gingivalis and its components

(Submitter supplied) Periodontitis is the most common human infection affecting tooth-supporting structures. It was shown to play a role in aggravating atherosclerosis. To deepen our understanding of the pathogenesis of this disease, we exposed human macrophages to an oral bacteria Porphyromonas gingivalis (P. gingivalis) either as live bacteria, or its lipopolysaccharide (LPS) or fimbria. Microarray data from treated macrophages or control cells were analyzed to define molecular signatures. more...
