RT Journal A1 Hildreth CJ T1 ANgiogenesis and cancer JF JAMA JO JAMA YR 2009 FD January 7 VO 301 IS 1 SP 26 OP 26 DO 10.1001/jama.2008.924 UL http://dx.doi.org/10.1001/jama.2008.924 AB Evidence that angiogenesis, the development of new blood vessels, is important for tumor progression prompted interest in drugs that inhibit angiogenesis-promoting proteins, such as vascular endothelial growth factor (VEGF). Now, however, researchers from the University of California, San Diego, in La Jolla, have discovered VEGF-blocking drugs may actually accelerate tumor cell growth (Stockmann C et al.
