Role of an extracytoplasmic function sigma factor, PGN_0319, in hemin utilization by Porphyromonas gingivalis

(Submitter supplied) Extracytoplasmic function (ECF) sigma factors are known to play an important role in the bacterial response to various environmental stresses. Porphyromonas gingivalis, a prominent etiological agent in human periodontitis, possesses six putative ECF sigma factors. So far, information is limited on an ECF sigma factor, PGN_0319. It has been recently reported that the expression of genes encoding some of the ECF sigma factors including PGN_0319 was affected by hemin availability. more...

Role of HcpR in nitrosative stress protection

(Submitter supplied) HcpR has been shown to be required for growth of Porphyromonas gingivalis in the presence of nitrite (Infect Immun. 2012 Sep;80(9):3319-31. doi: 10.1128/IAI.00561-12. Epub 2012 Jul 9). It also has been shown to regulate the expression of hcp. To define the entire regulon of HcpR RNAseq examination of the wild type and mutant (deficient in HcpR) strains have been used to define the regulon in response to nitrite exposure in bacteria grown in the presence and absence of nitrite. more...

Influence of oxygen limitation, absence of the cytochrome bc1 complex and low pH on global gene expression in Gluconobacter oxydans 621H using DNA microarray technology

(Submitter supplied) The genome-wide transcriptional responses of the strictly aerobic -proteobacterium Gluconobacter oxydans 621H to oxygen limitation, to the absence of the cytochrome bc1 complex, and to low pH were studied using DNA microarray analyses. Oxygen limitation caused expression changes of 486 genes, representing 20% of the chromosomal genes. Genes with an increased mRNA level included those for terminal oxidases, the cytochrome bc1 complex, transhydrogenase, two alcohol dehydrogenases, heme biosynthesis, PTS proteins, proteins involved in cyclic diGMP synthesis and degradation, two sigma factors, flagella and chemotaxis proteins, several stress proteins, and a putative exporter protein. more...

The involvement of CdhR in Porphyromonas gingivalis during Nitric Oxide stress [RNA-seq]

(Submitter supplied) To understand the role of CdhR and its adjacent gene PG1236 in nitric oxide (NO) stress resistance, isogenic mutants P. gingivalis FLL457 (ΔPG1237::ermF), FLL458 (ΔPG1236::ermF) and FLL459 (ΔPG1236-37::ermF) were made by allelic exchange mutagenesis and their gene expression was studied under control and NO stress conditions. DNA microarray analysis of FLL457 showed that approximately 2% of the genes were up regulated and over 1% of the genes down regulated. more...

Zymomonas mobilis oxygen stress responses

(Submitter supplied) Zymomonas mobilis ZM4 produces near theoretical yields of ethanol with high specific productivity and recombinant strains are able to ferment both C-5 and C-6 sugars. However, the genetic and physiological basis of the ZM4 response to various industrially-relevant stresses is poorly understood. In this study, the dynamics of ZM4 oxygen stress responses were elucidated by characterizing the transcriptomic and metabolomic profiles of aerobic and anaerobic fermentations using whole-genome microarray analysis and gas chromatography-mass spectrometry. more...

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...

Identification of bistable populations of Porphyromonas gingivalis that differ in epithelial cell invasion.

(Submitter supplied) Bistable populations of bacteria give rise to two or more subtypes that exhibit different phenotypes. We have explored whether the periodontal pathogen, Porphyromonas gingivalis, exhibits bistable invasive phenotypes. Using a modified cell invasion assay, we show for the first time that there are two distinct sub-types within a population of P.ginigivalis strains NCTC 11834 and W50 that display differences in their ability to invade oral epithelial cells. more...
