Runx2 and Axin2 regulate skeletal development. We recently determined that Axin2 and Runx2 molecularly interact in differentiating osteoblasts to regulate intramembranous bone formation, but the relationship between these factors in endochondral bone formation was unresolved. To address this, we examined the effects of Axin2 deficiency on the cleidocranial dysplasia (CCD) phenotype of Runx2(+/-...

Recently, we have described that siRNA-mediated silencing of runt-related transcription factor 2 (RUNX2) improves anti-cancer drug gemcitabine (GEM) sensitivity of p53-deficient human pancreatic cancer AsPC-1 cells through the augmentation of p53 family TAp63-dependent cell death pathway. In this manuscript, we have extended our study to p53-mutated human pancreatic cancer Panc-1 cells. Accordi...

Background: The osteogenic Runt-related (RUNX) transcription factor Runx2 is frequently elevated in osseous and non-osseous tumor cells. Result: Genomic RUNX2 target genes were identified, and RUNX2 depletion reduces cell motility and adhesion in osteosarcoma cells. Conclusion: RUNX2 regulates cell motility and adhesion in osteosarcoma cells. Significance: RUNX2 may also control migration of no...

Runx2/Cbfa1 is essential for osteoblast differentiation and bone formation. Runx2 null mice (Runx2(-/-)) completely lack mineralized tissue and die soon after birth, whereas Runx2 heterozygous knock-out mice (Runx2(+/-)) stay alive but show morphological defects in the skeletal system as observed in cleidocranial dysplasia (CCD) in humans. The aim of this study is to elucidate the role of Runx2...

Past studies have revealed the critical role of runt-related transcription factor 2 (RUNX2) in the proliferation and differentiation of mesenchymal stem cells (MSCs). This study therefore aimed to investigate the expression profile of the RUNX2 gene in human bone marrow MSCs and its biological characteristics. Bone marrow MSCs were separated from 12 patients who had received hip joint replaceme...

The transcription factor Runx2 has been reported to promote epithelial-mesenchymal transition (EMT) in many tumors. Vasculogenic mimicry (VM) is described as the mimicry of endothelial cells by tumor cells to form microvascular tubes in aggressive tumors. Galectin-3 has been reported to regulate cell invasion, migration, and VM formation; it could be regulated by Runx2. However, the relationshi...

RUNX2 is a member of the runt family of DNA-binding transcription factors. RUNX2 mediates endothelial cell migration and invasion during tumor angiogenesis and is expressed in metastatic breast and prostate tumors. Our published studies showed that RUNX2 DNA-binding activity is low during growth arrest, but elevated in proliferating endothelial cells. To investigate its role in cell proliferati...

PURPOSE Previously, FTY720 was found to possess potent anticancer effects on various types of cancer. In the present study, we aimed to first verify the role of Runx2 in prostate cancer progression and metastasis, and, subsequently, assessed if FTY720 could modulate Runx2 expression, thus interfering downstream events regulated by this protein. EXPERIMENTAL DESIGN First, the association betwe...

Dentin sialophosphoprotein (DSPP) consists of dentin sialoprotein (DSP) and dentin phosphoprotein (DPP). The spatial-temporal expression of DSPP is largely restricted during differentiational stages of dental cells. DSPP plays a vital role in tooth development. It is known that an osteoblast-specific transcription factor, Runx2, is essential for osteoblast differentiation. However, effects of R...

background: objective: the stem cell theory in the endometriosis began the advanced avenue of targeting these cells as the novel therapy to eliminate endometriosis. in this regards, studies showed that lovastatin alters the cells from a stem-like state to a more differentiated condition and reduces the stemness. the aim of this study was to investigate whether lovastatin treatment could influen...
