Pulmonary Artery Sarcoma Overexpressing Platelet-derived Growth Factor Receptor α
Pulmonary artery sarcoma is highly malignant and easily metastasizes to the systemic organs. Both the introduction of novel diagnostic procedures and the development of new treatment modalities are required to achieve long-term survival. Several studies have shown that platelet-derived growth factor receptor α (PDGFRα) gene amplification is frequently observed in pulmonary artery sarcoma. PDGFR...
متن کاملStage specific requirement of platelet-derived growth factor receptor-α in embryonic development
BACKGROUND Platelet-derived growth factor receptor alpha (PDGFRα) is a cell-surface receptor tyrosine kinase for platelet-derived growth factors. Correct timing and level of Pdgfra expression is crucial for embryo development, and deletion of Pdgfra caused developmental defects of multiple endoderm and mesoderm derived structures, resulting in a complex phenotypes including orofacial cleft, spi...
متن کاملCharacterization of the platelet-derived growth factor receptor-α-positive cell lineage during murine late lung development.
A reduced number of alveoli is the structural hallmark of diseases of the neonatal and adult lung, where alveoli either fail to develop (as in bronchopulmonary dysplasia), or are progressively destroyed (as in chronic obstructive pulmonary disease). To correct the loss of alveolar septa through therapeutic regeneration, the mechanisms of septa formation must first be understood. The present stu...
متن کاملPlatelet-derived growth factor receptor alpha (pdgfr-α) gene in zebrafish embryonic development
Here we present the cloning of a full-length zebrafish pdgfr-a cDNA as well as the expression of this gene during zebrafish embryogenesis. We show that zebrafish pdgfr-a mRNA is present at high levels in the fertilized egg as well as in all embryonic cells up to the end of gastrulation. Spatially restricted expression of the gene started after the onset of segmentation and is mainly localized i...
متن کاملCharacterization of platelet-derived growth factor and platelet-derived growth factor receptor expression in asbestos-induced rat mesothelioma.
Although altered expression of platelet-derived growth factor (PDGF) is a hallmark of human mesothelioma, expression of PDGF receptors has not been characterized in this cell type. In addition, the expression of this growth factor and its cognate receptor in rodent mesothelioma has not been investigated. In this study, examination of transformed mesothelial cells derived from asbestos-induced r...
