Ults show that changes in the BORIS transcript levels are associated with those of MAGE-A1 and corroborate that BORIS is involved in the activation of MAGE-A1 gene expression.BORIS affects the DNA methylation pattern of MAGE-A1 geneFigure 2 BORIS mRNA expression in MDA-MB-468, MCF-7 and BCM1 cells, untreated or treated with 5-aza-CdR. RT-PCR products of BORIS mRNA were separated on an agarose gel.
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
