Scientists said that they have isolated a gene that instructs the body to build tiny new blood vessels, a crucial step in cancer growth, and that this could open new strategies to defeat malignancies. The researchers who purified and analyzed the protein, angiogenin, which the gene controls, said it is the first time that an organ-forming protein has been understood in detail. The discovery represents 10 years of work by Dr. Bert L. Vallee and colleagues at Harvard Medical School.
