Using tropomyosin polymorphic phenomenon for detection of differences between rat spontaneous tumor cells and their in vitro oncovirus supertransformats.


Biochemical and immunological comparative studies of rat tumor cells of spontaneous origin and in vitro supertransformed cell populations have been done. We have focused on characterization of differences in tropomyosin molecular forms in the individual cell populations. Our experiments have shown that differences of tropomyosin forms exist not only between spontaneous transformants and supertransformants but also between supertransformants and normal rat fibroblasts. It means that superinfection of spontaneous transformants by avian sarcoma virus B77 have induced changes in tropomyosin synthesis but a pattern of tropomyosin forms in super-transformants has not been equal or similar to that of normal fibroblasts.
