Vascular growth factors play an important role in maintaining the structure and integrity of the glomerular filtration barrier. In healthy adult glomeruli, the proendothelial survival factors vascular endothelial growth factor-A (VEGF-A) and angiopoietin-1 are constitutively expressed in glomerular podocyte epithelia. We demonstrate that this milieu of vascular growth factors is altered in stre...
Objective: To examine how aspirin affects the healing of gastric ulcer and angiogenesis. Hematopoietic progenitor cells expressing vascular endothelial growth factor receptor-1 (VEGFR1) promote angiogenesis. We examined the involvement of progenitor cells during the process of ulcer healing. Methods: Gastric ulcers were induced by the serosal application of 100% acetic acid in mice treated with...
Increasing evidence suggests that myeloid bone marrow-derived cells (BMDCs) play a critical role in lung metastasis. Blockade of VEGF receptor 1 (VEGFR1) has been proposed as a potential strategy to limit myeloid BMDC recruitment to tumors. However, preclinical evidence indicates that this strategy may not be effective in all tumors. Thus, establishing which molecular mechanisms are responsible...
BACKGROUND While vascular endothelial growth factor (VEGF) expression in breast tumors has been correlated with a poor outcome in the pathogenesis of breast cancer, the expression, localization, and function of VEGF receptors VEGFR1 (also known as FLT1) and VEGFR2 (also known as KDR or FLK1), as well as neuropilin 1 (NRP1), in breast cancer are controversial. METHODS AND FINDINGS We investiga...
Preclinical studies have suggested that VEGFR1-positive cells potentially foster the development of metastases by establishing a "premetastatic niche." We sought to test this hypothesis in high-risk localized prostate cancer and assess potential niche modulation by the VEGFR1-targeting drug axitinib. Formalin-fixed, paraffin-embedded tissue derived from benign lymph nodes was collected and VEGF...
Autocrine VEGF/VEGFR1 signaling in a subpopulation of cells associates with aggressive osteosarcoma.
UNLABELLED Osteosarcoma is the most common primary bone malignancy and accounts for more than half of primary skeletal malignancies in children and young adults. Although vascular endothelial growth factor (VEGF) expression in osteosarcoma has been associated with poor outcome, its role in the pathogenesis of osteosarcoma remains controversial. Here, VEGF and VEGFR1 expression in both human and...
OBJECTIVE Angiogenesis and lymphangiogenesis are complex phenomena that involve the interplay of several growth factors and receptors. Recently, we have demonstrated that in Keratin-14 (K14) promoter-driven Vegf-A transgenic (Tg) mice, not only angiogenesis but also lymphangiogenesis is stimulated. However, the mechanism by which VEGFR1 is involved in lymphangiogenesis remains unclear. METHOD...
The aim of the study to evaluate the prognostic significance of vascular endothelial growth factor receptor 1 and 2 (VEGFR1/2) expression levels and to correlate these levels with clinicopathological parameters in patients with cervical cancer.Forty-two patients with International Federation of Gynecology and Obstetrics Stage IIB-IVB cervical cancer were analyzed between January 2011 and Decemb...
