Transcriptional regulation of bone formation by the osteoblast-specific transcription factor Osx
Bone formation is a complex developmental process involving the differentiation of mesenchymal stem cells to osteoblasts. Osteoblast differentiation occurs through a multi-step molecular pathway regulated by different transcription factors and signaling proteins. Osx (also known as Sp7) is the only osteoblast-specific transcriptional factor identified so far which is required for osteoblast dif...
متن کاملSynergistic Inhibition of Wnt Pathway by HIF-1α and Osteoblast-Specific Transcription Factor Osterix (Osx) in Osteoblasts
Osterix (Osx) is an osteoblast-specific transcription factor required for osteoblast differentiation. Inhibition of Wnt pathway by Osx highlights the potential for feedback control mechanisms involved in bone formation. Hypoxia-inducible factor-1α (HIF-1α) is a master regulator of hypoxia. HIF-1α has been reported to couple angiogenesis to osteogenesis. Our recent study has demonstrated that Os...
متن کاملRegulation of the osteoblast-specific transcription factor Osterix by NO66, a Jumonji family histone demethylase
Osterix (Osx) is an osteoblast-specific transcription factor required for osteoblast differentiation and bone formation. Osx null mice develop a normal cartilage skeleton but fail to form bone and to express osteoblast-specific marker genes. To better understand the control of transcriptional regulation by Osx, we identified Osx-interacting proteins using proteomics approaches. Here, we report ...
متن کاملTranscriptional Regulation by Competing Transcription Factor Modules
Gene regulatory networks lie at the heart of cellular computation. In these networks, intracellular and extracellular signals are integrated by transcription factors, which control the expression of transcription units by binding to cis-regulatory regions on the DNA. The designs of both eukaryotic and prokaryotic cis-regulatory regions are usually highly complex. They frequently consist of both...
متن کاملTranscriptional regulation of bone formation.
Bone formation in vertebrates depends on the proliferation and differentiation of chondrocytes and osteoblasts, which are derived from a mesenchymal precursor cells and are required for skeletal development. This process relies on many transcription factor genes that have functions in bone cell proliferation and differentiation. Over the years, various transcription factors that play essential ...
