Expression of BC200 RNA in tumor cell lines Expression levels in MCF-10A cells, MCF-7 cells, BHK cells, and HeLa cells were established by qRT-PCR BC200 RNA expression was significantly elevated in MCF-7 cells and HeLa cells, in comparison with MCF-10A cells (the latter normalized to 1) Quantitative analysis: one-way ANOVA, p=0.0003; Dunnett’s post hoc analysis, comparison of MCF-7 cells (p<0.001) and of HeLa cells (p<0.01) with MCF-10A cells BHK cells were usedas a negative control as expression of BC200 RNA is specific to primates2.
