Project description:Recent epidemiological studies revealed a significant association between oral squamous cell carcinoma (OSCC) and Porphyromonas gingivalis, a major pathogen of periodontal disease. As a keystone pathogen, P. gingivalis is known not only to damage local periodontal tissue, but also to evade from the host immune system and eventually affect systemic health. However, its role in OSCC has yet to be well studied. To explore the underlying effect of chronic P. gingivalis infection on OSCC and to identify relevant biomarkers as promising targets for therapy and prevention, we established a novel model by exposing human immortalized oral epithelial cells (HIOECs) to P. gingivalis at a low MOI for 5 to 23 weeks. The P. gingivalis-infected HIOECs were monitored in tumor biological alteration. Bioinformatics analyses were performed on HIOECs infected for 15 weeks, and some selected data were validated by q-PCR and (or) Western blot on cells infected for 15 and 23 weeks. Accordingly, we found that persistent exposure to P. gingivalis induced tumor biological properties on HIOECs. Tumor-related genes such as NNMT, FLI1, GAS6, lncRNA CCAT1, PDCD1LG2 and CD274 were aberrantly expressed in response to long-term exposure of P. gingivalis. In addition, some clinical biomarkers and novel proteins were presented. In conclusion, chronic P. gingivalis infection may be a potential risk factor of OSCC. The key regulators and biomarkers might be used in monitoring OSCC with chronic periodontal infection. We applied lncRNA Microarray (Affymetrix) which could simultaneously detect coding and non-coding genes to explore the differences of cell gene expression after long-term exposure to P. gingivalis.

Project description:Porphyromonas gingivalis, the keystone pathogen responsible for dysbiosis in the oral microbiome, the development of periodontal diseases, and the contribution to systemic comorbidities, is a heme auxotroph. It encodes only four enzymes in the heme biosynthesis pathway, namely HemD, HemN, HemG, and HemH. HemH protein is a ferrochelatase involved in the final step of heme biosynthesis by inserting iron ions (Fe2+) into protoporphyrin IX. This study aimed to analyze the effect of hemH gene deletion on P. gingivalis gene expression, thereby verifying its importance for P. gingivalis.

Project description:The oral periodontal pathogen Porphyromonas gingivalis must adapt to ever changing environment to survive and cause disease. So far most of the efforts concerning the regulatory mechanisms employed by the bacterium centered on DNA-binding regulators. Here we focused on a RNA-binding protein that is indispensable for the bacterium to survive with host cells. We have determined the proteome affected by deletion of the protein, designated here PgRBP1. Three strains were used: WT, PgRBP1-deficient strain designated V3139 and a complemented strain V3236. In total, 1,393 proteins were identified. 592 proteins in the comparison of P. gingivalis 3139 vs. WT, 228 proteins in the comparison of P. gingivalis 3236 vs. WT, and 276 proteins in the comparison of P. gingivalis 3139 vs. 3236 showed differential level with statistical significance

Project description: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. In addition we used ISR sequence analysis to determine the relatedness of P. gingivalis strains to one another, and demonstrated a link between ISR sequence phylogeny and the disease-associated phenotype of P. gingivalis strains. The availability of whole genome microarrays based on the genomic sequence of strain W83 has allowed a more comprehensive analysis of P. gingivalis strain variability, using the entire genome. The objectives of this study were to define the phylogeny of P. gingivalis strains using the entire genome, to compare the phylogeny based on genome content to the phylogeny based on a single locus (ISR), and to identify genes that are associated with the strongly disease-associated strain W83 that could be important for virulence.
