L line BCM1, the expression of both genes is opposite: no levels of MAGE-A1 [2^(Ct) 1.07] and high levelsof BORIS [2^(Ct) 24.39]. We transiently transfected expression plasmid encoding BORIS into both cell lines, with negligible transcript levels of MAGE-A1, and quantified endogenous MAGE-A1 mRNA by RT (reverse transcription)-PCR and gel electrophoresis. As depicted in Figure 1, BORIS was able to
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
Ion levels of BORIS in MDA-MB-468, MCF-7 and BCM1 cells by RT-PCR and gel electrophoresis. As expected, we found a similar expression profile of BORIS mRNA (Figure 2) to that detected by quantitative real-time PCR (Table 1). However, gel electrophoresis and quantitative real time showed no and low expression levels of BORIS in MCF-7 cells, respectively, but the tendency was similar. The additional

Nhibitor TSA or after transient transfection of these cells with an expression plasmid encoding for BORIS were separated on an agarose gel. The bar chart shows the relative changes in mRNA expression levels of MAGE-A1 in MCF-7 cells by quantitative real-time PCR. The significant p-values are shown (C). H2O lane serves as a negative control. The housekeeping gene -Actin was selected as an internal
