Quantitative expression of VEGF, VEGF-R1, VEGF-R2, and VEGF-R3 in melanoma tissue microarrays

VEGF and EG-VEGF

Vascular endothelial growth factor (VEGF) plays an essential role in angiogenesis. This includes developmental angiogenesis as the loss of a single allele is embryonic lethal due to lack of development of endothelial cells. During early development, endothelial cells depend on VEGF for survival and if it is withdrawn, massive apoptosis results. This is not true in adult organisms; withdrawal of...

The relationship of the angiogenesis regulators VEGF-A, VEGF-R1 and VEGF-R2 to p53 status and prognostic factors in epithelial ovarian carcinoma in FIGO-stages I-II.

The aim of this study was to evaluate prognostic effect of the angiogenesis regulators VEGF-R1, VEGF-R2 and VEGF-A for recurrent disease and disease-free survival (DFS), and their relation to the apoptosis regulator p53, in 131 patients with FIGO-stages I-II with epithelial ovarian cancer. For the detection of positivity of the markers the techniques of tissue microarrays and immunohistochemist...

Coexpression of VEGF receptors VEGF-R2 and neuropilin-1 in proliferative diabetic retinopathy.

PURPOSE To elucidate vascular endothelial growth factor (VEGF)-mediated pathogenesis of fibrovascular proliferation in diabetic retinopathy. METHODS Fibrovascular tissues were obtained at vitrectomy from 22 cases with proliferative diabetic retinopathy. The half-divided tissues were processed for reverse transcription-polymerase chain reaction (RT-PCR) analysis to examine the expression of VE...

Co-localization of prothrombin fragment F1+2 and VEGF-R2-bound VEGF in human colon cancer.

BACKGROUND Colon cancer (CC) is frequently complicated by thromboembolic episodes. Thrombin plays a role in angiogenesis and among others induces the synthesis of vascular endothelial growth factor (VEGF) and its receptors (VEGFR-1 and VEGFR-2). The aim of this study was to assess the expression of prothrombin fragment F1+2 (F1+2), a byproduct in thrombin generation (indicating the presence of ...
