ANGIOGENESIS UPENDED
Targeting Vessel Abnormalization in Cancer
| The first 150 words of the full text of this article appear below. |
The role of angiogenesis in cancer is now so well accepted that it's easy to forget how young the field is. New discoveries still have the power to change how people think about blood vessels and cancer. The latest example: deltalike ligand 4 (DLL4).
DLL4 is generating intense interest because it offers a new way to use angiogenesis, or new blood vessel formation, against tumors. At least three biotech companies are now racing each other to be first in the clinic with a DLL4-blocking drug, a milestone that will probably come sometime next year. Activity "has really heated up," said Jan Kitajewski, Ph.D., a cancer researcher at Columbia University in New York.
One reason for the buzz is DLL4's link to vascular endothelial growth factor (VEGF). VEGF is thought to be the dominant growth factor driving angiogenesis in cancer; bevacizumab (Avastin), Genentech's FDA-approved colorectal and lung cancer drug, targets VEGF.
