We studied the effect of 5-aza-2'-deoxycytidine (5-AZA-CdR) on the differentiation of murine 41A3 neuroblastoma cells. Neuroblastoma cells treated with 0.1-1.0 microM 5-AZA-CdR underwent differentiation; markers of neuronal functions, such as acetylcholinesterase activity and growth of nerve fibers, were expressed at a higher level in the drug-treated cells than in the controls. This increased expression was accompanied by significant hypomethylation of newly synthesized DNA. A secondary event seemed to be a partial inhibition of DNA synthesis, cell proliferation and colony-forming activity. These effects were more pronounced than those caused by the related cytidine analog, 1-beta-D-arabinosil-cytosine (ARA-C). The results obtained suggest that 5-AZA-CdR may be an effective agent for the growth control of human neuroblastoma cells.
