Cleidocranial dysplasia (CCD) is a dominantly inherited skeletal dysplasia caused by mutations in the osteoblast-specific transcription factor-encoding gene, RUNX2. To correlate different RUNX2 mutations with CCD clinical spectrum, we studied six independent Chinese CCD patients. In five patients, mutations were detected in the coding region of the RUNX2 gene, including two frameshift mutations...
Osteoblast maturation plays a key role in regulating osteogenesis. Electrospun nanofibrous products were reported to possess a high surface area and porosity. In this study, we developed chitosan nanofibers and examined the effects of nanofibrous scaffolds on osteoblast maturation and the possible mechanisms. Macro- and micro observations of the chitosan nanofibers revealed that these nanoprodu...
The "runt domain" (RD) is a 128 amino acid region of the Drosophila pair-rule gene runt. This highly conserved region delineates the DNA-binding domain of a new family of transcription factors; the RD proteins. The family includes genes from Drosophila, chicken and mammals that are involved in a wide range of developmental processes, from sex determination and neurogenesis in Drosophila to hema...
OBJECTIVES To study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. MATERIALS AND METHODS Forty New Zealand rabbits were randomly divided into five groups with eight rabbits in each group. For each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. To t...
Cleidocranial dysplasia (CCD) is a skeletal dysplasia with autosomal-dominant inheritance. The runt related transcription factor 2 (RUNX2) gene is the only gene in which mutations are known to cause CCD. We report identification of a novel small deletions mutation in the RUNX2 gene in a Chinese family with CCD. A 29-year-old female was diagnosed as proband of CCD based on the clinical findings,...
The drawbacks of traditional bone-defect treatments have prompted the exploration of bone tissue engineering. This study aimed to explore suitable β-tricalcium phosphate (β-TCP) granules for bone regeneration and identify an efficient method to establish β-TCP-based osteo-regenerators. β-TCP granules with diameters of 1 mm and 1-2.5 mm were evaluated in vitro. The β-TCP granules with superior o...
The Runt domain transcription factor, PEBP2/CBF, is a heterodimer composed of 2 subunits. The DNA-binding alpha subunit, or RUNX protein, interacts with a partner PEBP2beta/CBFbeta through the evolutionarily conserved Runt domain. Each of the genes encoding RUNX1 and PEBP2beta/CBFbeta is frequently involved in acute myeloid leukemia. The chimeric protein, CBFbeta(PEBP2beta)/SMMHC, is generated ...
Decreased bone formation contributes to the development of bone lesions in multiple myeloma (MM) patients. In this study, we have investigated the effects of myeloma cells on osteoblast formation and differentiation and the potential role of the critical osteoblast transcription factor RUNX2/CBFA1 (Runt-related transcription factor 2/core-binding factor Runt domain alpha subunit 1) in the inhib...
