Serum vascular endothelial growth factor in late rheumatoid arthritis.

OBJECTIVES To investigate the serum levels of VEGF in patients with rheumatoid arthritis of long duration. METHODS Serum VEGF levels were measured in 118 patients with long-standing rheumatoid arthritis according to the ACR criteria (mean duration 12 years). The disease activity score was evaluated by the method of van der Heijde et al. RESULTS Serum levels of VEGF in patients with RA were ...

Correlation Between Soluble Vascular Endothelial Growth Factor A, Its Receptor 1 And Response To Chemotherapy In Acute Leukemia In Children

  Background and Objective: Vascular endothelial growth factor (VEGF) and its receptors (VEGF-R1 and R2) are major regulators of angiogenesis. This study was designed to assess serum levels of VEGF and VEGF-R1 and their prognostic significance in newly diagnosed childhood acute leukemia. Materials and Methods: For this purpose, VEGF and VEGF-R1 were determined using enzyme linked immuno-sorba...

Involvement of Flt-1 tyrosine kinase (vascular endothelial growth factor receptor-1) in pathological angiogenesis.

Vascular endothelial growth factor (VEGF) and its two receptors, Fms-like tyrosine kinase 1 (Flt-1) (VEGFR-1) and KDR/Flk-1 (VEGFR-2), have been demonstrated to be an essential regulatory system for blood vessel formation in mammals. KDR is a major positive signal transducer for angiogenesis through its strong tyrosine kinase activity. Flt-1 has a unique biochemical activity, 10-fold higher aff...

Signaling of vascular endothelial growth factor receptor-1 tyrosine kinase promotes rheumatoid arthritis through activation of monocytes/macrophages.

Vascular endothelial growth factor (VEGF) and VEGF receptor-1 (VEGFR-1/Flt-1) were shown to be involved in pathological angiogenesis, particularly rheumatoid arthritis (RA). However, the molecular basis of their actions is not fully understood. Here we report that in a murine model of RA, deletion of the tyrosine kinase (TK) domain of VEGFR-1 decreased the incidence and clinical symptoms of RA....

Study of correlation between vascular endothelial growth factor receptor and some prognostic factors in papillary carcinoma of thyroid gland

Background and Objective: Thyroid cancer is the most frequent endocrine malignancy in the world and papillary carcinoma is the most frequent thyroid carcinoma. Different markers used for determination of prognosis and VEGFR is one of them. The aim of present study was to determine the expression of Vascular Endothelial Growth Factor Receptor (VEGFR) as a prognostic marker in papillary carcinoma...
