Project description:Porphyromonas gingivalis (P. gingivalis) 381 and W83 growing in motility condition (i.e. stabbed in soft agar culture) and on surface of solid agar culture (Biofilm) were prepared. Applied medium was BAPHK supplemented with hemin and menadione . The cultures were then permitted to grow anaerobically at 37°C for 24 hours, which corresponds to initial stages of surface translocation by 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. Significant changes in gene expression were observed in cells growing in motility and biofilm modes , and the majority of changes were associated with cell surface proteins, membrane proteins, biosynthesis of folates and bioenergetic pathways.
Project description:Human primary aortic smooth muscle cells were infected with wild type (W50, 381), W50 derived gingipain mutants (E8 and K1A), or 381 derived fimbriae mutants (DPG3 and KRX178) strains of Porphyromonas gingivalis for 24 hours. The RNA was extracted from the cells and human whole genome microarray were used to measure gene expression.
Project description:Wild type Porphyromonas gingivalis strain ATCC33277 (V3176) and PG1626 - deficient mutant (V3177) were grown in iron replete conditions was used to compare to Porphyromonas gingivalis strains grown in iron chelated conditions.
Project description:Porphyromonas gingivalis and Treponema denticola are periodontalpathogens that are associated with the severity and progression of periodontal diseases. This study investigates the gene expression of Porphyromonas gingivalis during co-culture with Treponema denticola
