Recent studies indicate that high mobility group box protein 1 (HMGB1) originating from periodontal ligament (PDL) cells can be a potential regulator in the process of orthodontic tooth movement and periodontal tissue remodeling. The aim of this study is to investigate HMGB1 expression in periodontal tissue during orthodontic tooth movement in mice(More)
Periostin is essential for the integrity and function of the periodontal ligament (PDL), and periostin knockout is related to an enhanced inflammatory status in PDL. High mobility group box 1 (HMGB1), a late inflammatory cytokine, is up-regulated in PDL cells in response to mechanical stress. This study aimed to investigate the effect of periostin(More)
Vitamin D has an anabolic effect on bone developmental processes and is involved in maintaining skeletal integrity. In recent years, pediatric cases of vitamin D intoxication have attracted attention. Therefore, the aim of this study was to investigate the influence of long-term administration of physiologically-high-dose calcitriol (1,25(OH)2D3) on bone(More)
The purpose of this study was to investigate the effect of zoledronate (ZA) on osteoclast functions and viability in the tibiae of 8-week-old male mice. After weekly intravenous administration of ZA (125 μg/kg body weight) for 8 weeks, the mice were fixed by transcardial perfusion of 4 % paraformaldehyde under anesthesia, and their tibiae were extracted for(More)
High mobility group box 1 (HMGB1) is a late inflammatory cytokine that plays an important role in periodontal tissue remodeling during orthodontic tooth movement. Calcitriol (1,25-dihydroxyvitamin D3 [1α,25 (OH)2D3]) is a systemic calcium-regulating hormone shown to downregulate expression of multiple proinflammatory cytokines in human periodontal ligament(More)
The aim of the present study was to investigate the expression of matrix metalloproteinase (MMP)9 and MMP2, and their potential roles in bone metastasis nests using a well-standardized model of breast cancer bone metastasis in nude mice. BALB/c nu/nu mice (5-week-old; n=10) were subjected to intracardiac injection of MDA-MB-231 human breast cancer cells.(More)
The aim of this experiment was to elucidate the histological alterations after systemic administration of eldecalcitol (ELD) combined with guided bone regeneration during the restoration of bone defect healing in rats. The femurs of 8-week-old Wister rats were used to generate bone defect models. The defect was covered with a collagen membrane, and ELD(More)
