cardiovascular system
artery stenosis ( J:104130 )
• a greater than 3-fold and 10-fold increase in neointimal thickening and Brd-U incorporation, respectively, are seen after injury of the femoral artery designed to mimic restenotic lesions; however no abnormalities are seen in the absence of injury
abnormal physiological neovascularization ( J:104130 )
• increased angiogenesis is seen in matrigel plugs and aortic ring cultures; however no obvious abnormalities are seen in unstressed mice
abnormal tumor vascularization ( J:104130 )
• neovascularization of tumor implants is increased compared to littermate controls
abnormal vascular wound healing ( J:104130 )
• a greater than 3-fold and 10-fold increase in neointimal thickening and Brd-U incorporation, respectively, are seen after injury of the femoral artery

homeostasis/metabolism
abnormal vascular wound healing ( J:104130 )
• a greater than 3-fold and 10-fold increase in neointimal thickening and Brd-U incorporation, respectively, are seen after injury of the femoral artery

neoplasm
abnormal tumor vascularization ( J:104130 )
• neovascularization of tumor implants is increased compared to littermate controls
