Platelet-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 کاملPulmonary 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 کاملمهار مسیرهای سیگنالی فاکتورهای رشد توسط داروی ایماتینیب مسیلات در سلول‌های لایدیگ نرمال موشی
Background & Aims : Cancer cells proliferation may be mediated by abnormal phosphorylation of signaling pathways downstream of tyrosine kinase receptors such as Platelet derived growth factor receptor α (PDGFR-α) and β (PDGFR-β). We aimed to study the phosphorylation level of PDGFR-α and PDGFR-β and apoptosis in mouse normal leydig cells being exposed to Imatinib. Materials & Methods : The ...
متن کاملPlatelet-derived growth factor B chain promoter contains a cis-acting fluid shear-stress-responsive element.
The endothelial lining of blood vessels is constantly exposed to fluid mechanical forces generated by flowing blood. In vitro application of fluid shear stresses to cultured endothelial cells influences the expression of multiple genes, as reflected by changes in their steady-state mRNA levels. We have utilized the B chain of platelet-derived growth factor (PDGF-B) as a model to investigate the...
متن کاملS1P3-mediated Akt activation and cross-talk with platelet-derived growth factor receptor (PDGFR).
Akt plays a pivotal role in cell survival and tumorigenesis. We investigated the potential interaction between sphingosine-1-phosphate (S1P) and platelet-derived growth factor (PDGF) in the Akt signaling pathway. Using mouse embryonic fibroblasts (MEFs) from S1P receptor knockout mice, we show here that S1P3 was required for S473 phosphorylation of Akt by S1P. In addition, S1P-stimulated activa...
