In this study, treatment of lymphoid tumor cells with low dose clofarabine upregulated the expression of Sp17 and SPAN-Xb. This was associated with an increase in hypomethylated CpG dinucleotides and a decrease in global DNA methylation, as demonstrated by decreases in the percent of methylated Alu repeats. ⋯ Above this, clofarabine resulted in tumor cell growth inhibition and apoptosis. Our results provide the first evidence for the CT antigen-inducing and DNA hypomethylating property of low concentration clofarabine.
