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
