Because the increase in erythroid mRNA steady-state level in anthracycline -treated cells was inhibited by cycloheximide , this suggests that transcriptional activation in ACLA -treated cells and mRNA stabilization in DOX -treated cells were dependent on de novo protein synthesis .
 ( cell type: anthracycline -treated cells, None) , ( cell type: DOX -treated cells, None) , ( RNA: erythroid mRNA, None) , ( cell line: ACLA -treated cells, None)
