HIF1A and neoplasm: To gain more insight into the relationship between BTG3 and tumor angiogenesis in human cancer, we analyzed available datasets in public domains using the PROGgeneV2 platform (http://genomics.jefferson.edu/proggene)38 for the association of patient survival and the relative expression of BTG3 and VEGFA, a main downstream target of HIF-1 in angiogenesis.
