Figure 6. ERβ2 expression is high in breast tumor samples with low ERα expression and negatively correlates with PHD3 expression.

Figure 6

(A) qPCR analysis of ERα mRNA level of 50 human breast cancer tissues determined ERα-low expression (n=20) and ERα-high expression (n = 30) breast tumors. Data represent means ± SD. ***P < 0.001. (B) qPCR analysis of ERβ2 mRNA level in ERα-low expression tumor samples compared to ERα-high expression breast tumor samples. Data represent means ± SD. *P < 0.05. (C) Negative correlation of PHD3 mRNA expression to ERβ2 mRNA expression in ERα-low expression breast tumors. *P < 0.05.
