Induction of sister chromatid exchange by polyoma large viral tumor antigen in transformed rat fibroblasts.
The frequency of sister chromatid exchange (SCE) was determined in rat fibroblasts transformed by wild-type polyoma virus or by a mutant temperature sensitive for viral large tumor antigen function (ts-a). Elevated SCE frequencies were observed in two wild-type transformed cell lines growing at 37 degrees and in four ts-a-transformed lines upon growth at the permissive temperature for large vir...
متن کاملp53-plus-ras-transformed rat embryo fibroblasts express tumor-specific transplantation antigen activity which is shared by independently transformed cells.
p53-plus-ras-transformed rat cell lines express a tumor-specific transplantation antigen that is common to a number (85%) of independently derived p53-plus-ras-transformed cell lines. This has been shown by immunizing rats with irradiated p53-plus-ras-transformed cells and demonstrating protection of these animals by subsequent live-cell tumor challenge. Several c-myc-plus-ras-transformed cell ...
متن کاملTumor Rejection by Modulation of Tumor Stromal Fibroblasts
Interleukin (IL)-4-secreting tumors are rejected in mice, an effect that is thought to be immune mediated. However, solid tumors are embedded in a stroma that often contains tumor-promoting fibroblasts, a cell population whose function is also affected by IL-4. Here we show that IL-4-secreting tumors grew undiminished in IL-4 receptor (R)-deficient (IL-4R-/-) mice. In IL-4R+/+ mice they were lo...
متن کاملModulation of the transformed and neoplastic phenotype of rat fibroblasts by MHC-I gene expression.
Transfection of the activated ras oncogene (Ha-ras) into second passage rat embryo fibroblasts can induce the metastatic phenotype, while cotransfection of Ha-ras with the adenovirus type 2 E1a gene (Ad2-E1a) yields cells which are tumorigenic but nonmetastatic in nude mice. Because of the presence in nude mice of natural killer cells and B-lymphocytes, which might account for the different met...
