Cycloheximide-dependent reversion of human cells transformed by MSV and chemical carcinogen

HY Cho and JS Rhim

The protein synthesis inhibitor cycloheximide, at a concentration of 0.08 microgram per milliliter, induced flat morphology within 24 to 48 hours and low saturation density in human osteosarcoma cells transformed by Kirsten murine sarcoma virus (Ki-MSV) or N-methyl-N' nitro-N-nitrosoguanidine. Removal of the protein synthesis inhibitor caused both transformed cells to revert to the transformed phenotype. The demonstration of cell-surface antigens, cross-reacted with antiserums induced by extracts of both types of transformed human cells, was dependent on the presence or absence of cycloheximide in the culture medium. The results show that protein synthesis is required to maintain the transformed state in virally or chemically transformed human cells.
