Abstract

Expression of various oncogenes (ras, myc, erbB2, src, fyn, yes and sis) in a high‐metastatic clone (MH‐02) derived from a murine methylcholanthrene‐induced fibrosarcoma A (Meth A) was compared with those of its parent clone (ML‐01) by Northern blot analysis. Two oncogenes, fyn, belonging to the tyrosine‐kinase family, and sis, belonging to the cellular‐growth‐factor family, were found to have higher signals (3.6‐fold and 1.8‐fold respectively) in MH‐02 than in ML‐01 cells. To explore the possibility that higher expression of these oncogenes is involved in enhanced metastasis of the MH‐02 clone, ML‐01 was transfected by a fyn vector and the metastatic potential of the transfectant was examined. Mice administered fyn‐transfected ML‐01 cells had significantly increased metastatic nodules in the lung, as compared with those whose ML‐01 cells were transfected with control vector without the fyn gene. The result indicates that the fyn gene is one of the factors governing the metastatic potential of Meth A cells.
