(Submitter supplied) Oal anaerobic bacteria have to face constant oxidative stress in order to survive in the inflammatory environment of the periodontal pocket. In this study, we analyzed the transcriptome profiles of P. gingivalis and Filifactor in monoculture as compared to P. gingivalis+F.alocis coculture under H2O2 stress condtions, to analyze the genes responsible for enhanced survival of P. gingivalis in presence of F. more...

(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...

(Submitter supplied) Porphyromonas gingivalis (P. gingivalis) W83 cultures in early exponential phase were supplemented with 0.1% galactose or vehicle control. The cultures were then permitted to grow anaerobically at 37°C for 3 hours, which corresponds to approximately one doubling of P. gingivalis. At this point, RNA extraction was performed using the cultures, and these samples were processed and submitted for RNA sequencing using an Illumina platform. more...

(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...

(Submitter supplied) Background: With lower manufacturing cost, high spot density, and flexible probe design, genomic tiling microarrays are ideal for comprehensive transcriptome studies. Typically, transcriptome profiling using microarrays involves reverse transcription, which converts RNA to cDNA. The cDNA is then labeled and hybridized to the probes on the arrays, thus the RNA signals are detected indirectly. Reverse transcription is known to generate artifactual cDNA, in particular the synthesis of second-strand cDNA, leading to false discovery of antisense RNA. more...
