Polyomavirus transforms rat F111 and mouse NIH 3T3 cells by different mechanisms.


Polyomavirus middle tumor antigen (mT) was expressed in a line of mouse NIH 3T3 cells under control of the dexamethasone-regulatable mouse mammary tumor virus promotor. Contrary to rat F111 cells which were rendered anchorage independent by mT expression alone (L. Raptis, H. Lamfrom, and T.L. Benjamin, Mol. Cell. Biol. 5:2476-2487, 1985), mT-producing NIH… (More)
