Tumor growth requires induction of an angiogenic program, and targeting of this program with antiangiogenic drugs shows an impact on tumor progression. However, although they are effective at reducing angiogenesis, these therapies have not produced widespread or enduring clinical benefit, which openly exposes their limitations. Here, we describe the current(More)
Antiangiogenic drugs are used clinically for treatment of renal cell carcinoma (RCC) as a standard first-line treatment. Nevertheless, these agents primarily serve to stabilize disease, and resistance eventually develops concomitant with progression. Here, we implicate metabolic symbiosis between tumor cells distal and proximal to remaining vessels as a(More)
The mechanisms of tumor growth and progression involve the activation of different processes such as neovascularization and angiogenesis. These processes involve tumoral cells and stromal cells. Hence, inhibiting angiogenesis affects tumor growth and proliferation in patients with different types of cancer. Nevertheless, tumoral cells and stromal components(More)
The longitudinal effect of an anti-vascular endothelial growth factor receptor 2 (VEGFR-2) antibody (DC 101) therapy on a xenografted renal cell carcinoma (RCC) mouse model was monitored using hybrid diffuse optics. Two groups of immunosuppressed male nude mice (seven treated, seven controls) were measured. Tumor microvascular blood flow, total hemoglobin(More)
Several types of tumor are currently treated with antiangiogenic drugs. Unfortunately, most of these patients develop therapy resistance and succumb to the disease. Recently, a novel mechanism of resistance to antiangiogenics involving metabolic symbiosis of tumor cells has been described. Strategies to block resistance are emerging as a promising(More)
Angiogenesis and metabolism are entwined processes that permit tumor growth and progression. Blood vessel supply is necessary for tumor survival not only by providing oxygen and nutrients for anabolism but also by removing waste products from cellular metabolism. On the other hand, blocking angiogenesis with antiangiogenic therapies shows clinical benefits(More)
CanCer Cells are Cells that have lost their capacity to divide in a controlled manner. They give rise to a neoplastic lesion that is supported by stromal cells. Both tumor cells and stromal cells contribute structurally and functionally to tumor development. Nevertheless, the tumor mass is typically limited to a size of 1–2 mm3, because further growth(More)
