Ahr and Cyp1b1 expression is increased in ALDH1high Hs578T cells. (a) ER−/PR−/HER2− Hs578T cells were stained with ALDEFLUOR™ in the presence or absence of diethylaminobenzaldehyde (DEAB), a specific ALDH inhibitor, and ALDH activity (production of fluorescent substrate) was quantified by flow cytometry. Regions were set using dot plots from DEAB-treated cells. Data are representative of 24 experiments. (b) Ahr and Cyp1b1 mRNA expression in sorted ALDHhigh and ALDHlow cells was quantified by RT-qPCR. Data from three independent experiments were analyzed using the Pfaffl method [103], normalized to the Gapdh signal, and presented as mean fold-change from ALDHlow ± standard error. Asterisks indicate a significant increase in the mRNA fold-change, *P <0.05, **P <0.005
