Ets1 and ERα expression in human breast cell lines.

<p>A. Breast cell lines were analyzed by Western blot for ERα and Ets1 with tubulin as a loading control. B. ER-positive BT-474, MCF7, T47D and ZR-75-1 cells were analyzed by qRT-PCR for Ets1 transcript levels. Data represent mean ± standard deviation. Ets1 transcript levels are statistically significantly lower in BT-474, MCF7, T-47D and ZR-75-1 cells compared to MCF10A cells by ANOVA with Tukey’s post-test analysis p<0.001.
