ABSTRACT
Microinjection of early simian virus 40 (SV40) DNA fragments has shown that maximal transformation of rat cells (Ref 52) is a property of the second SV40 T-antigen exon. Expression of this particular T-antigen region was obtained by coinjection of the Taq/Bam DNA fragment with the early promoter/enhancer HpaII/BglI fragment. Microinjection of the DNA fragment mixture induced two categories of transformants; namely, maximally and minimally transformed cells. The maximally transformed cells synthesize two Taq/Bam-specific polypeptides, and the minimally transformed cells only the lower molecular weight form. Both types of transformants contain the cellular p52 protein at high concentrations. Furthermore, maximal transformation of Ref 52 cells requires the carboxy terminus of the T-antigen. Cells transformed by microinjection of the SV40 Pst A-fragment display different parameters of maximally transformed cells but not anchorage-independent growth.
