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.

Upregulate MAGE-A1 expression in this cell line. BORIS-specific shRNA reduced the BORIS mRNA expression nearly completely in presence and absence of scramble shRNA (Figure 3D, p = 0.0001). Likewise, the downregulation of MAGE-A1 expression by BORIS-specific shRNA was more prominent in MCF-7 cells than in MDA-MB-468 cells. As measured by quantitative real time PCR, BORIS-specific shRNA reduced the
