In Lab Mice. We know the proteins work on mice but the important thing is determining whether they work on people.
Researchers hope within a year to begin testing the drugs on humans.
Given intravenously, tumors in mice have shrunk and disappeared altogether. A major development in the work to find cancer inhibitors came more than a decade ago when Folkman and other researchers developed a first generation of cancer-inhibiting drugs that slowed the growth of tumors in animals. Experiments with these early cancer inhibitors in human patients over the last five years have shown tumor-shrinkage as well, Folkman said. The new proteins take the cancer therapy one step further.
