Figure 1From: Estrogen promotes stemness and invasiveness of ER-positive breast cancer cells through Gli1 activationEndogenous expression of ER, Gli1 and ALDH1 in human breast cancer cells lines. MRNA levels of (A) ER, (B) Gli1 and (C) ALDH1 were measured using real-time RT-PCR. (D & E) Linear correlation assays were used to analyze the relationship between ER and Gli1 (D) or ER and ALDH1 (E) expression levels.Back to article page
