Researchers at National Jewish Medical and Research Center have identified a protein that inhibits the formation of new blood vessels. Combined with previous findings that the protein is depleted or missing in a majority of metastatic human cancers, the findings suggest that fibulin-5 may one day be an effective cancer therapy. William Schiemann, Ph.D., Assistant Professor in the Program in Cell Biology at National Jewish, and postdoctoral fellow Allan R. Albig reported their findings in the June issue of DNA and Cell Biology.
