Abstract
Sustained angiogenesis, through either local sprouting (angiogenesis) or the recruitment of bone marrow-derived cells (BMDCs) (vasculogenesis), is essential to the development of a tumor. How BMDCs are recruited to the tumor and their contribution to the tumor vasculature is poorly understood. Here, we demonstrate that both IL-8 and angiogenin contribute to the complementary pathways of angiogenesis and BMDC mobilization to increase tumor growth. These two factors are regulated by PHD2 in a HIF-independent but NF-κB-dependent manner. PHD2 levels are decreased in human cancers, compared with corresponding normal tissue, and correlate with an increase in mature blood vessels. Thus, PHD2 plays a critical role in regulating tumor angiogenesis.
