FST expression is reduced in breast cancer cell lines compared with nontransformed mammary epithelial cells. a Western blot analysis of breast cancer cell lines demonstrating loss of FST expression compared with nontransformed (NT) mammary epithelial cells. b FST expression in MCF10A versus MCF10A-Neu stable cell lines that overexpress rat c-Neu/ErbB2 [27]. FST was assessed by quantitative RT-PCR relative to TATA-binding protein (TBP) mRNA (**p < 0.01). (PPTX 1925 kb)
