Bmp-Encoding Adenoviral Vector Tethered to Dental Implants Enhances Bone Regeneration In article number 2200531, Shogo Maekawa, Young-Dan Cho, William Giannobile, and co-workers demonstrate that immobilizing bone morphogenetic protein (BMP) genes onto the surfaces of dental implants by chemical vapor deposition technology enhances regeneration.
Bone Morphogenetic Protein-2 (BMP-2) is highly overexpressed in the majority of patient-derived lung carcinomas. However, a mechanism revealing its role in cancer has not been established. Here we report that BMP-2 enhances the neovascularization of developing tumors. Recombinant BMP-2 stimulated blood vessel formation in tumors formed from A549 cells injected s.c. into thymic nude mice. Recomb...
During ectodermal patterning the neural crest and preplacodal ectoderm are specified in adjacent domains at the neural plate border. BMP signalling is required for specification of both tissues, but how it is spatially and temporally regulated to achieve this is not understood. Here, using a transgenic zebrafish BMP reporter line in conjunction with double-fluorescent in situ hybridisation, we ...
Bone morphogenetic proteins (BMPs), a subgroup of the TGF-β superfamily, play critical roles in neural progenitor cell fate determination. Neural stem cells (NSCs) are multipotent progenitor cells that can differentiate into neurons, oligodendrocytes and astrocytes under certain conditions. In our recent report, using an antibody that can recognize both BMP-2 and BMP-4 (BMP-2/4), we showed that...
Bone morphogenetic protein-2 (BMP-2) is an evolutionary conserved protein that is essential for embryonic development. BMP-2 is highly expressed in approximately 98% of human lung carcinomas with little expression in normal lung tissues. BMP-2 has been shown to enhance mobility, invasiveness, and metastasis of cancer cell lines. During development, BMP-2 induces the proto-oncogene phosphoinosit...
Bone morphogenetic protein 9 (BMP-9) is a member of the transforming growth factor (TGF)-beta/BMP superfamily, and we have demonstrated that it is one of the most potent BMPs to induce osteoblast differentiation of mesenchymal stem cells (MSCs). Here, we sought to investigate if canonical Wnt/beta-catenin signalling plays an important role in BMP-9-induced osteogenic differentiation of MSCs. Wn...
Introduction. Bone morphogenetic protein-2 (BMP-2) is a member of BMP family of proteins. In human, it has role in skeletal repair and regeneration, as well as in heart formation. Kidneys of BMP-2 heterozygous null mutant mice have normal gross anatomy, but exhibit increased ureteric bud branching. Dysregulation of BMP-2 signaling has been suggested in carcinogenesis. Methods. We determined BMP...
In Xenopus, the biological effects of BMP-3 oppose those of ventralizing BMPs, but the mechanism for this antagonism remains unclear. Here, we demonstrate that BMP-3 is a dorso-anteriorizing factor in Xenopus embryos that interferes with both activin and BMP signaling. BMP-3 acts by binding to ActRIIB, the common type II receptor for these proteins. Once BMP-3 binds to ActRIIB, it cannot be com...
We investigated whether impaired regulation of bone morphogenetic protein-2 (BMP-2) via epigenetic pathways is associated with renal cell carcinoma (RCC) pathogenesis. Expression and CpG methylation of the BMP-2 gene were analyzed using RCC cell lines, and 96 matched RCC and normal renal tissues. We also performed functional analysis using BMP-2 restored RCC cells. A significant association of ...
Heparin displays several types of biological activities by binding to various extracellular molecules, including pivotal roles in bone metabolism. We have previously reported that heparin competitively inhibits the binding activity of bone morphogenic protein-2 (BMP-2) to BMP and the BMP receptor (BMPR) and suppresses BMP-2 osteogenic activity. In the present study, we examined whether heparin ...
