Vascular Endothelial Growth Factor, a Key Modulator of the Anti-Tumor Immune Response
2021
During tumor growth, angiogenesis is required to ensure oxygen and nutrient transport to the tumor. Vascular endothelial growth factor (VEGF) is the major inducer of angiogenesis and appears to be a key modulator of the anti-tumor immune response. Indeed, VEGF modulates innate and adaptive immune responses through direct interactions and indirectly by modulating protein expressions on endothelial cells or vascular permeability. The inhibition of the VEGF signaling pathway is clinically approved for the treatment of several cancers. Therapies targeting VEGF can modulate the tumor vasculature and the immune response. In this review, we discuss the roles of VEGF in the anti-tumor immune respon…
Bone marrowVEGFCexpression is associated with multilineage dysplasia and several prognostic markers in adult acute myeloid leukemia, but not with sur…

Vascular endothelial growth factor C (VEGFC) stimulates leukemia cell proliferation and survival, and promotes angiogenesis. We studied VEGFC expression in bone marrow samples from 353 adult acute myeloid leukemia (AML) patients and its relationship with several clinical, cytogenetic, and molecular variables. We also studied the expression of 84 genes involved in VEGF signaling in 24 patients. We found that VEGFC expression was higher in AML patients with myelodysplasia-related changes (AML-MRC) than in patients with non-AML-MRC. We also found an association between VEGFC expression and the patient cytogenetic risk group, with those with a worse prognosis having higher VEGFC expression leve…
Combination of Resveratrol with omega-3 fatty acids synergize to counteract VEGF-R pathway in sick retinal pigment epithelium cells mimicking AMD
2015
Purpose The aim of this work is to assess whether RSV (Resveratrol) can act synergistically with omega-3 fatty acids to modulate VEGF (Vascular Endothelial Growth Factor) signaling pathway in order to identify a new and more effective therapy for the treatment of AMD (Age-Related Macular Degeneration). Methods In this study, undifferentiated and differentiated human retinal pigment epithelial cells (ARPE-19) were used. The cells were treated with an omega-3/RSV preparation (Resvega®), or a RSV-free formulation or RSV alone for 24 h. The expression of key proteins in VEGF signaling pathway was evaluated by Western Blotting. Results We observed that the combination omega-3/RSV preparation (Re…
