title: Oncogene expression in human hepatoma cells PLC/PRF/5.
abstract: The expression of 7 cellular oncogenes in a human hepatoma cell line PLC/PRF/5 was studied using Northern blot analyses. Among the oncogenes tested, c-abl, c-fes, c-fms, c-myc, c-Ha-ras and c-sis were expressed. The oncogene c-Ki-ras was not expressed. The length of the mRNAs expressed was almost consistent with published data. Compared to the oncogene expression in Daudi lymphoma cells, the same kind of oncogenes were expressed in PLC/PRF/5 cells, but the intensity of the signal in each oncogene expression was stronger in Daudi cells than in PLC/PRF/5 cells. Considering the cellular localization and the function of each oncogene, the oncogene survey in hepatoma cells broadens the knowledge of hepatocarcinogenesis and the character of human hepatoma cells.
