Transformed foci were formed by cotransfection with adenovirus type 12 E1A (Adl2E1A) and activated c-Ha-ras (EJras) oncogenes, and with c-myc and EJras oncogenes. Transfection with c- myc, Ad12E1A or EJras induced no obvious foci. Transformed cell lines established from each trans- formed focus had high saturation densities in culture and were tumorigenic when injected into athy- mic mice with low-differetiated sarcoma. The transfected oncogene DNA sequences were detected in the cellular DNA of all the transformants. Alkaline phosphatase activity decreased in transformants compared to their parental MC3T3-E1 cells.}, pages = {233--240}, title = {癌遺伝子によるマウス骨芽細胞株MC3T3-E1のトランスフォーメーショソ}, volume = {60}, year = {1991} }
