Abstract：
:The purpose of this study was to determine whether the degree of anchorage-independent growth of rodent or human cells in increasing concentrations of agarose correlated with successful transfection of the cells with an activated c-Ha-ras oncogene and tumorigenicity in nude mice. NIH 3T3 cells, C3H 10T1/2 fibroblasts, four clones of the murine K-1735 melanoma with different metastatic capacities and the TE85 human osteogenic sarcoma line were transfected with plasmids containing the 6.6-kilobase BamHI fragment of the mutant human c-Ha-ras gene and the neo gene, which confers resistance to neomycin (pSV2-neoEJ). Cells transfected with pSV2-neo, a plasmid containing the neo gene, served as controls. Cells from parental or transfected lines (selected by Geneticin) were plated into medium containing 0.3%, 0.6% 0.9%, or 1.2% agarose. These cells were also injected subcutaneously and intravenously into nude mice. The production of tumor cell colonies in dense agarose (greater than or equal to 0.6%) correlated with successful transfection with pSV2-neoEJ and production of experimental metastases in the lung of nude mice. We conclude that the degree of anchorage-independent growth of cells predicts successful transfection with activated c-Ha-ras oncogene and tumorigenic behavior in vivo. Thus this technique may be useful for the detection of cells transfected with transforming oncogenes.
