Transplantation resistance to a Rous sarcoma virus-induced tumor in mice immunized with v-src protein.
It is of great interest in tumor immunology to know whether oncogene products could be used not only as tumor markers for cancer diagnosis, but also as immunogens for cancer therapy. BALB/c mice immunized with syngeneic fibroblasts, Escherichia coli cells producing p60v-src, or the purified p60v-src protein extracted from the E. coli producer cells showed transplantation resistance to a Rous sarcoma virus-induced tumor but not a Kirsten sarcoma virus-induced tumor. In contrast, mice immunized with cells not producing p60v-src or their derived proteins or with chicken ovalbumin did not show any significant resistance. These findings suggest that p60v-src can act as a specific transplantation rejection antigen in mice.
