Angiogenesis
Studies from J.H. Lee and colleagues yield new information about angiogenesis
October 14th, 2008
"Interferon regulatory factor-1 (IRF-1) is a tumor suppressor and transcriptional modulator that can regulate gene expression involved in cell growth control, induction of apoptosis, and post-translation modification. In this study, we found that IRF-1 inhibits endothelial cell angiogenesis using human umbilical vein endothelial cell (HUVECs) culture system," investigators in South Korea report. "In addition, IRF-1 directly inhibited the tube formation of endothelial cells on Matrigel and reduced the expression of p-Akt, and p-eNOS, which play a significant role in angiogenesis when stimulated by VEGF. We also demonstrate that C-terminal region including transactivation...
