A Cancer Cure 40 years ago, the use of Peptides
All cancer drugs share a problem: They penetrate just a few cells into the tumor. Now a team of biologists has identified a molecule that helps cancer treatments dive deep into tumors, at least in mice. The approach still needs to be tested in people, but if it pans out, it will circumvent one of the biggest challenges in the field. “This has huge implications for cancer therapy,” says David Cheresh, a tumor and vascular biologist at the University of California (UC), San Diego, who was not involved in the work. source: http://news.sciencemag.org/sciencenow/2010/04/new-peptide-helps-cancer-drugs-b.html
