Epithelial differentiation of adipose-derived stem cells (ADSCs) is mediated by sophisticated interactions of various molecular functions and biological processes, including transcriptional regulation. Runt-related transcription factor 2 (RUNX2) increases osteoblast and adipocyte differentiation of ADSCs. However, the role of RUNX2 in epithelial differentiation of ADSCs is unknown. We first sho...

Prolyl hydroxylase (PHD) inhibitors are suggested as therapeutic agents for tissue regeneration based on their ability to induce pro-angiogenic responses. In this study, we examined the effect of the PHD inhibitor dimethyloxalylglycine (DMOG) on odontoblast maturation and sought to determine the underlying mechanism using MDPC-23 odontoblast-like cells. DMOG significantly enhanced matrix minera...

Supernumerary teeth and tooth agenesis are common morphological anomalies in humans. We previously obtained evidence that supernumerary maxillary incisors form as a result of the successive development of the rudimentary maxillary incisor tooth germ in Usag-1 null mice. The development of tooth germs is arrested in Runx2 null mice, and such mice also exhibit lingual epithelial buds associated w...

Prostate cancer patients with regional lymph node involvement at radical prostatectomy often experience disease progression to other organs, with the bone as the predominant site. The transcription factor Runx2 plays an important role in bone formation and prostate cancer cell migration, invasion, and metastasis. Here we showed that the forkhead box O (FOXO1) protein, a key downstream effector ...

Cleidocranial dysplasia (CCD) is a rare congenital disorder, typically characterized by persistently open skull sutures, aplastic or hypoplastic clavicles, and supernumerary teeth. Mutations in the gene encoding the runt-related transcription factor 2 (RUNX2) protein are responsible for approximately two thirds of CCD patients. We report a 20-year-old CCD patient presenting not only with typica...

We report an unusual combination of features comprising delayed tooth eruption and closure of the anterior fontanel as the sole presenting features in a child with cleidocranial dysplasia (CCD). Radiological survey revealed the presence of wormian bones in the skull, pseudoepiphysis at the base of the bilateral second metacarpal, and midline ossification defects at pubic symphysis in the presen...

We aimed to evaluate the regulatory effects of miR-148a-3p on stem cell osteogenic differentiation and enamel development by targeting runt-related transcription factor 2 (RUNX2) E-cadherin, respectively. TargetScan software was utilized predict binding sites between marker gene RUNX2 or E-cadherin. The changes in expression during epidermal cells were detected. After transfection with mimics i...

The Runt box domain DNA-binding transcription factors (RUNX) play key roles in hematopoietic, bone, and gastric development. These factors regulate angiogenesis and tumorigenic events, functioning as either activators or repressors of target genes. Although RUNX2 is an essential bone maturation factor, it has also been found to promote transformation in vivo and cell proliferation in vitro, per...

Runt-related transcription factor 2 (Runx2) is essential for osteogenesis. This study aimes at identification of the genomic region differentially methylated in DNA for regulation of Runx2 expression. In the proximal promoter of mouse Runx2, DNA methylation was frequent at the region further than 3 kb relative to the transcription start site, in contrast to lower methylation status of the close...

Runx2 regulates osteogenic differentiation and bone formation, but also suppresses pre-osteoblast proliferation by affecting cell cycle progression in the G(1) phase. The growth suppressive potential of Runx2 is normally inactivated in part by protein destabilization, which permits cell cycle progression beyond the G(1)/S phase transition, and Runx2 is again up-regulated after mitosis. Runx2 ex...
