Project description:Comparative metatranscriptomic analysis in peri-implantitis and periodontitis
| PRJDB3765 | ENA
Project description:Purpose: The aim of this study was to explore whether differences exist and to what an extent of the immune-mediated inflammatory reactions between periodontitis and peri-implantitis at the transcriptional level in the same susceptible host. Methods: Ligature-induced experimental peri-implantitis and periodontitis in the same mice were established. Gingival tissues of healthy, periodontitis and peri-implantitis sites from the same oral cavity were collected and used for RNA-sequencing. Differentially expressed genes (DEGs) were screened between periodontitis/peri-implantitis sites and healthy sites. The enrichment analysis of DEGs were analyzed. Comprehensive immune landscape was annotated by seq-ImmuCC. Results: The results showed that 137 and 353 up-regulated DEGs as well as and 670 and 174 down-regulated DEGs were specifically expressed periodontitis/peri-implantitis group compared to the healthy control group, respectively. The pathways of complement and coagulation cascade and osteoclast differentiation were dominating in the peri-implantitis sites. Moreover, peri-implantitis sites exhibited elevated macrophage proportions and relatively enriched macrophage activation and bone loss compared with periodontitis. Conclusions: Results indicated that peri-implantitis and periodontitis exhibited significantly distinct transcriptional signatures. Additionally, the study suggests that the interplay between macrophages and bone resorption are comparatively more active in peri-implantitis compared with periodontitis. These biological processes may be factors contributing to the pathogenesis of peri-implantitis being distinct from that of periodontitis.

Project description:Comparison of bacterial flora of peri-implantitis and periodontitis using DNA
| PRJDB6966 | ENA
Project description:This study included 20 participants (10 healthy subjects and 10 patients with periodontitis and peri-implantitis). Gingival tissue samples (10 healthy, 10 periodontitis, and 10 peri-implantitis tissues) were collected, RNAs were extracted, and RNA sequencing and analysis were performed.

Project description:Comparison of bacterial flora of peri-implantitis and periodontitis before and after treatment part1
| PRJDB9396 | ENA
Project description:Objectives: The aim of this study was to identify the long noncoding RNAs (lncRNAs) and mRNAs that influence the different manifestations of peri-implantitis and periodontitis (I vs. P). Materials and methods: Gingival tissues from 6 peri-implantitis patients, 6 periodontitis patients, and 6 healthy individuals were analysed using lncRNAs and mRNAs gene expression microarrays. A lncRNAs subgroup analysis, a lncRNAs cluster graph, gene ontology (GO), and a pathway analysis of mRNAs were performed to analyse the data extracted from microarrays. To verify the results of the microarray studies, quantitative real-time polymerase chain reaction (qRT-PCR) was used to assess some differentially expressed lncRNAs and mRNAs. Results: In the gene expression microarray studies, 1,079 differentially expressed lncRNAs and 1,003 differentially expressed mRNAs were identified when comparing I vs. P. The lncRNAs subgroup analysis showed that there were 9 significantly up-regulated antisense lncRNAs and 18 significantly down-regulated antisense lncRNAs when comparing I vs. P. GO analysis on mRNAs revealed that the cyclooxygenase pathway is the most prominent signal among the up-regulated transcripts (3 genes) and that hemidesmosome assembly represents the most significant biological process among the down-regulated transcripts (4 genes) when comparing I vs. P. The expression levels of antisense lncRNA GACAT2 and mRNA MTCL1, antisense lncRNA MSC-AS1 with its sense mRNA MSC and TRPA1 were verified by RT-qPCR. Conclusions: Results indicated that peri-implantitis and periodontitis exhibit significantly different lncRNAs and mRNAs expression profiles. Additionally, specific lncRNAs may take part in the pathogenesis mechanisms of peri-implantitis and periodontitis through influencing their nearby mRNAs.

Project description:Analysis microbial composition of peri-implantitis and periodontitis by 16S rRNA genes pyrosequencing
| PRJDB2403 | ENA
Project description:Transcriptome analysis of oral tissue samples taken from peri-implantitis and healthy control patients Peri-implantitis is a condition resulting in destructive inflammation in the peri-implant soft tissue barrier. Clinically, it demonstrates vast clinical differences to periodontitis that suggests distinct inflammatory mechanisms. Implant-derived Titanium particles (i-TiPs) frequently found around diseased implants appear to alter the microenvironment and confer resistance to antibiotic treatments. Studies in orthopedic implants have demonstrated a strong inflammatory response to i-TiPs, involving a variety of cell types, in aseptic conditions. Nonetheless, the genetic programs of cells surveilling and supporting the peri-implant soft tissue barrier in response to the combined challenges of biomaterial degradation products and oral bacteria are poorly defined. Thus, we studied gene expression specific to oral peri-implant inflammatory disease. We found that certain cellular pathways were highly upregulated in diseased tissues. Upregulated pathways provided insight into important physiological pathways that might play a role in peri-implant pathology. These findings could potentially contribute to the production of more targeted and effective therapeutics for the disease.
