Correlation between tumor-specific surface antigens and src gene expression in Rous sarcoma virus-induced rat tumors. 1983

N Kuzumaki, and H Minakawa, and T Matsuo, and S Haraguchi, and T O Yoshida

Immunization with Rous sarcoma virus (RSV)-induced mouse tumors or with SR-3Y1 or NY8-3Y1 rat fibroblasts transformed by a wild type RSV or an env gene deletion mutant of RSV induced complete transplantation resistance against an RSV-induced mouse tumor (CSA1M) in syngeneic hosts. On the other hand, 10 of 19 mice immunized with ts68-3Y1 rat fibroblasts transformed by an src gene temperature-sensitive mutant of RSV (permissive temperature: 33-35 degrees C) could not reject the CSA1M. SR-3Y1, NY8-3Y1 and RSV-induced mouse tumors expressed a common tumor-specific cell-surface antigen (TSSA) detected by a syngeneic rat antiserum against NY8-3Y1. In ts68-3Y1, expression of the TSSA was temperature-sensitive, TSSA being detected only when ts68-3Y1 was cultivated at the permissive temperature. Immunoprecipitation showed that serum from a rabbit bearing an RSV-induced tumor detected a 60-kdalton protein in cell extracts from SR-3Y1 and NY8-3Y1. Antiserum to NY8-3Y1 failed to detect this protein. These results suggest that the tumor-specific surface antigen(s) on RSV-induced mammalian tumors was coded for by an RSV src gene that was not identical with the simple form of the 60-kdalton protein identified.

It is induced by infection with a transforming virus.	Transformation, Viral Cell,Viral Cell Transformation,Cell Transformations, Viral,Transformations, Viral Cell,Viral Cell Transformations
D003602	Cytotoxicity, Immunologic	The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.

D005347	Fibroblasts	Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules.	Fibroblast
D005814	Genes, Viral	The functional hereditary units of VIRUSES.	Viral Genes,Gene, Viral,Viral Gene
D006649	Histocompatibility Antigens	A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
