Activate the MAGE-A1 promoter and to which extent, we compared its influence with the stimulatory effect of 5-aza-CdR and/or TSA on MAGE-A1 transcription in cancer cell line settings. For our current investigations, we chose 3 breast cancer cell lines: MDA-MB-468, MCF-7 and BCM1 because of their different levels of MAGE-A1 and BORIS transcripts. As shown in Table 1 and measured by quantitative rea
