Project description:The mucosal penetration area formed by implant placement is critical problems of dental implant treatment, because epithelial barrier is broken and it can become a source of inflammation. To clarify the influence and risk caused by dental implant treatment in peri-implant soft tissue, we compared to gene expression profile of peri-implant soft tissue and oral mucosal tissue with microarray analysis.

Project description:Rationale：Poor peri-implant osseointegration of dental implants in patients with type II diabetes has become a major clinical challenge in recent years. MSC (Mesenchymal stem cell)-derived exosomes may play an important role in peri-implant osseointegration, but the mechanism remains unclear. Enhancing the therapeutic effect of MSC-derived exosomes and exploring the potential mechanism can help provide a new therapeutic strategy to improve the clinical outcome of dental implant restorations in patients with type II diabetes. Methods：The exosomes derived from hypoxia (Hypo-exos) or normoxia (Nor-exos) preconditioned bone marrow mesenchymal stem cells (BMSCs) were co-cultured with BMSCs and human umbilical vein endothelial cells (HUVECs). The effect of exosomes on BMSCs cell proliferation was detected by CCK-8 assay and EdU assay, and the effect on angiogenesis ability of HUVECs was detected by wound healing assay, transwell migration assay, tube formation assay, enzyme-linked immunosorbent assay (ELISA), quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. A diabetic rat dental implant model was also established and the effect of exosomes on implant osseointegration was evaluated through micro-CT scanning and histological analysis. The differentially expressed miRNAs between Hypo-exos and Nor-exos were identified by high-throughput miRNA sequencing. Subsequently, the target genes and their roles in regulating angiogenesis were predicted and analyzed by bioinformatics analysis and dual luciferase reporter assay. Results：In vitro experiments indicated that hypoxia preconditioning could elevate exosome production and promote cell proliferation of BMSCs and angiogenesis of HUVECs. Moreover, Hypo-exos promoted peri-implant osteogenesis in rats with diabetes. Further investigation revealed the vital involvement of the miR-106b-5p/HIF-1α axis in promoting peri-implant osseointegration. Conclusion: Exosomes derived from hypoxia-preconditioned BMSCs could improve the peri-implant osseointegration in rats with diabetes by promoting cell proliferation and angiogenesis, and the miR-106b-5p/ HIF-1α axis could be the underlying mechanism.

Project description:The mucosal penetration area formed by implant placement is critical problems of dental implant treatment, because epithelial barrier is broken and it can become a source of inflammation. To clarify the influence and risk caused by dental implant treatment in peri-implant soft tissue, we compared to gene expression profile of peri-implant soft tissue and oral mucosal tissue with microarray analysis. Both side upper first molars of 4 week-old rat were extracted, and titanium alloy implants were placed only in the left extraction socket. Four weeks after surgery, samples were harvested from left side of peri-implant soft tissue and right side of oral mucosal tissue.

Project description:Dysbiosis of subgingival microbiome promotes the growth of periodontopathogens and the development of periodontitis, an irreversible chronic inflammatory disease. Untreated periodontitis leads to the destruction of connective tissues, alveolar bone resorption and ultimately to tooth loss. Periodontitis has been associated with inflammatory metabolic diseases such as type 2 diabetes. While periodontitis-induced inflammation is a key player in both, the development of subgingival microbiome dysbiosis and in the host-microbiome interaction, the effects of hyperglycemia on the regulation of the host genes controlling the inflammatory response and the host-microbiome interaction are still scarce. We investigated the impacts of a hyperglycemic microenvironment on the inflammatory response and gene expression of a gingival fibroblasts-macrophages coculture model stimulated with dysbiotic subgingival microbiomes. A coculture model composed of immortalized human gingival fibroblasts overlaid with U937 macrophages-likes cells were stimulated with subgingival microbiome collected from four healthy donors and four patients with periodontitis. Pro-inflammatory cytokines and matrix metalloproteinase were measured by a Luminex assay while the coculture RNA was submitted to a microarray analysis. Subgingival microbiomes were submitted to 16s rRNA gene sequencing. Data were analyzed by using an advanced multi-omics bioinformatic data integration model. Our results showed that krt76, krt27, pnma5, mansc4, rab41, thoc6, tm6sf2, and znf506 as well as the pro-inflammatory cytokines IL-1, GM-CSF, FGF2, IL-10, the metalloproteinases MMP3 and MMP8, and bacteria from the ASV 105, ASV 211, ASV 299, Prevotella, Campylobacter and Fretibacterium genera are key correlated variables contributing to periodontitis-induced inflammatory response in a hyperglycemic microenvironment. To conclude, our multi-omics integration analysis unveiled unique differentially interrelated bacterial genera, genes and pro-inflammatory cytokines involved in the regulation of the inflammatory response in a hyperglycemic microenvironment. These data also highlight the importance of considering hyperglycemic conditions in the development of new drugs or treatments for periodontal disease in link with type 2 diabetes.

Project description:Type 2 diabetes mellitus(T2DM)patients are a concern for dentists due to the lower success rate of healing period implant treatment. Here, we firstly calculated the success rate of in the healing period of diabetic and non-diabetic patients in the implant center of our hospital.Then we investigated the potential risk factors by proteomics analysis of 5 T2DM implant faliure patients in our implant center and compared the difference between high glucose induction study model and mesenchymal stem cell model from diabetic patients. The results suggested that the significantly higher implant failure rates in the T2DM group and the cell models derived from patients can be more comprehensive and accurate in reflecting the exact situation of BMSCs in patients with diabetes.
