...virus was that of Stewart-Eddy polyoma, named for N.I.H.'s Drs. Sarah Stewart and Bernice Eddy (TIME, July 27). Team members stripped the protein overcoat from the virus particles to get the nuclear content. This proved to be a form of deoxyribonucleic acid, which has an enormously complex structure with a molecular weight of 2,000,000 or more...
...self-propagating cells, some form of DNA is the template that determines what form the daughter cells will take after subdivision. For cancer research, the significance of the polyoma-DNA work is that it showed how foreign DNA, invading normal cells, can upset their reproduction so that cancerous offspring result...
Antibody tests have proved that Dr. Grace's cancer-causing agent is not the polyoma virus. The answers to what it is and whether it will lead to protection against human cancer may take years (and millions of mice) to find...
Vaccination? By now, the SE (for Stewart-Eddy) polyoma (multiple-tumor) virus has hurdled the species barrier and caused cancers not only in mice but in rats and in Syrian and Chinese hamsters. In rabbits, for some strange reason, it causes only benign tumors. So far, Drs. Stewart and Eddy have not been able to infect monkeys with their virus, but a determined effort to do so is under way at Roswell Park Institute. Patricia, a lone baby monkey harboring polyoma virus, has her own spotless nursery where she is cared for by Nurse Althea Higgins. Drs. Stewart and Eddy...
