پیش زمینه و هدف: تکثیر سلول های سرطانی ممکن است از فسفوریلاسیون غیر طبیعی مسیرهای سیگنالی پایین دست گیرنده های تیروزین کینازی چون گیرنده های فاکتورهای رشد مشتق از پلاکت α (pdgfr-α) و β (pdgfr-β) ناشی شود. به دلیل نقش حیاتی این مسیرها در سلول های طبیعی، درمان سرطان ها با داروهای مهار کننده تیروزین کینازی مانند ایماتینیب مسیلات اغلب منجر به اختلالات عملکرد سلول های طبیعی همانند سلول های لایدیگ می...
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 ...
In this study, we aimed to determine VEGFR-2, EGFR and PDGFR-β tyrosine kinase inhibitory activities of some pyrrolo[2,3-d]pyrimidine derivatives previously synthesized and showed potent cytotoxic and apoptotic effects against several cancer cell lines by our group and to evaluate the relationships between inhibitory activities and binding properties of the active compounds by molecular docking...
Aim: In this study, we aimed to investigate the relationship between staining rates of thrombospondin-1, VEGF, and PDGFR-in tissue preparations in patients diagnosed with DLBCL their clinical features at time diagnosis, response treatment prognosis.
 Material Method: A total 44 a diagnosis 13 control reactive lymphadenopathy were included study. After immunohistochemical pathology patient ...
Platelet-derived growth factor (PDGF) and transforming growth factor-β (TGF-β) signaling are required for hepatic stellate cell (HSC) activation under pathological conditions such as liver metastatic tumor growth. These two signaling pathways are functionally divergent; PDGF signaling promotes proliferation and migration of HSCs, and TGF-β induces transdifferentiation of quiescent HSCs into myo...
The proliferation, migration, and angiogenesis of endothelial progenitor cells (EPCs) play critical roles in postnatal neovascularization and re-endothelialization following vascular injury. Here we evaluated whether the over-expression of platelet-derived growth factor receptor-β (PDGFR-β) can enhance the PDGF-BB-stimulated biological functions of EPCs through the PDGFR-β/phosphoinositide 3-ki...
Abstract Background and Aims Chronic kidney disease affects >10% of the world's population is associated with high mortality morbidity. The best predictor CKD progression extent fibrosis, i.e., pathological deposition extracellular matrix (ECM) loss functional parenchyme. Currently, there are no specific treatment options invasive biopsies remain gold standard for diagnosis. Multiple sig...
Introduction. The well-documented role of the PDGF system in tumor growth and angiogenesis has prompted the development of new biological agents targeting the PDGF system. The aim of the present study was to analyze the expression of the PDGF-receptors in ovarian cancer and to investigate its relation to histopathological parameters and long-term overall survival. Methods. The immunohistochemic...
BACKGROUND & AIMS Rapid induction of β-PDGF receptor (β-PDGFR) is a core feature of hepatic stellate cell activation, but its cellular impact in vivo is not well characterized. We explored the contribution of β-PDGFR-mediated pathway activation to hepatic stellate cell responses in liver injury, fibrogenesis, and carcinogenesis in vivo using genetic models with divergent β-PDGFR activity, and a...
AIMS Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is identified by aggregates of NOTCH3 extracellular domain (N3ECD) along capillaries and the deposition of granular osmiophilic material (GOM). We assessed the pattern of distribution of pericytes in relation to N3ECD deposits in cerebral microvessels of CADASIL subjects. METHODS We asses...
