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

ABSTRACT:

Background

The development of chronic periodontitis was due to not only periodontal pathogens, but also the interaction between periodontal pathogens and host. The aim of this study is to investigate the alterations in gene expression in Porphyromonas gingivalis (P.gingivalis) W83 after inoculation in rat oral cavity.

Results

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. Real-time quantitative PCR detection confirmed the expression alterations in some selected genes. Products of these upregulated and downregulated genes are mainly relate
