Abstract: | Summary This paper describes some current work pertaining to transformation of cells by oncogenic viruses. Part I includes: (1) the effect of a deoxyribonucleic acid (DNA) tumor virus (SV40) on the antigenic characteristics of transformed cells; (2) in vitro and in vivo methods of detecting virus-specific surface antigens; (3) the role that the host cell may play in the expression of virus-coded antigens; and (4) the presence of virus-induced antigens as a possible mechanism of the apparent nononcogenicity of certain virus variants. Part II discusses (1) the physicochemical properties of the nucleic acid of a ribonucleic acid (RNA) tumor virus-the Moloney sarcoma-leukemia virus (MSV-MLV) complex —(2) a preliminary analysis of viral RNA replication in cells transformed by MSV-MLV, and (3) application to human tumors.
