Table 1 Genes up-regulated (p < 0.0025 and ≥2 fold-change) after decitabine treatment identified using AffyChip.

From: Modulation by decitabine of gene expression and growth of osteosarcoma U2OS cells in vitro and in xenografts: Identification of apoptotic genes as targets for demethylation

IMP-3 8.36 nd yes Binds to insulin-like growth factor II leader 3 mRNA and may repress its translation during late development
NFKBIA 4.01 4.2 yes Inhibits NF-k-B and involved in cell adhesion, apoptosis, differentiation and growth
PAWR 3.30 10 yes Pro-apoptotic protein acts by down-regulating the anti-apoptotic protein BCL2 via its interaction with WT1
PDCD5 4.15 8 yes Induction of programmed cell death
PSG5 2.32 nd no Synthesized by syncitiotrophoblast of the placenta and has a role in maintenance of gestation
RAC2 5.09 nd no Involved in the regulation of the NADPH oxidase

  1. Fold change (Affy) is the Mean from a duplicate AffyChip experiments. The fold change using real-time PCR (TaqMan method) is the Mean values from the same RNA from the same yields that were used for the AffyChip experiments and a third replica. The direction of expression was consistent in the Affy experiment and the real-time experiment for the tested genes. 11 out of 13 genes have CpG-island in there 5' region. Genes in bold characters are those identified in the apoptotic pathway as explained in "Methods" and "Results". The genes are listed in alphabetical order.
