The antineoplastic effects of 5-aza-2'-deoxycytidine (5-AZA-CdR) and interferon-alpha (IFN-alpha) on human HL-60 myeloid leukemic cells were investigated. 5-AZA-CdR and IFN-alpha in combination produced a greater inhibition of DNA synthesis and cell growth than either agent alone. The co-treatment produced a synergistic reduction in the clonogenicity of the HL-60 leukemic cells. In addition, this combination also produced a greater reduction in mRNA expression for c-myc than each agent alone. This antileukemic action produced by 5-AZA-CdR and IFN-alpha in combination correlated with the increase in induction of differentiation of the HL-60 leukemic cells. These results suggest that 5-AZA-CdR and IFN-alpha in combination produces an enhancement of their antineoplastic action on HL-60 human myeloid leukemic cells.

D009857	Oncogenes	Genes whose gain-of-function alterations lead to NEOPLASTIC CELL TRANSFORMATION. They include, for example, genes for activators or stimulators of CELL PROLIFERATION such as growth factors, growth factor receptors, protein kinases, signal transducers, nuclear phosphoproteins, and transcription factors. A prefix of "v-" before oncogene symbols indicates oncogenes captured and transmitted by RETROVIRUSES; the prefix "c-" before the gene symbol of an oncogene indicates it is the cellular homolog (PROTO-ONCOGENES) of a v-oncogene.
