No expression of a Rous sarcoma virus-induced tumor antigen in mammalian cells infected with retroviruses transducing other oncogenes of the src gene family.
Immunization with mouse and rat cells transformed by Rous sarcoma virus (RSV) or by B77 avian sarcoma virus (ASV) induced complete transplantation resistance against an RSV-induced mouse tumor (CSA1M) in syngeneic hosts. In contrast, most of the mice immunized with a Fujinami sarcoma virus-transformed rat fibroblast line (FSV-3Y1), a feline sarcoma virus-transformed cat fibroblast line (FeSV-FEF), an Abelson leukemia virus-infected Balb/3T3 cell line (AbLV-3T3), or an uninfected 3Y1 cell line could not reject the CSA1M. Serologic analysis with the use of a complement-dependent cytotoxicity assay supported the results of transplantation studies. The mouse and rat cells transformed by RSV or B77 ASV expressed a common tumor-specific cell surface antigen (TSSA) detected by syngeneic antiserum against the CSA1M, whereas none of the FSV-3Y1, FeSV-FEF, and AbLV-3T3 cells expressed the TSSA. These results suggest that the common TSSA in the mouse and rat cells transformed by RSV or B77 ASV containing src gene is not shared with mammalian cells infected with retroviruses transducing other oncogenes of the src gene family (i.e., fps, fes, and abl).
