    ATCC bt474
    EBA impairs cancer stem cell-like properties. (A) <t>BT474</t> and SKBR3 cells were treated with EBA for 48 h, and ALDH1 activity was assessed by flow cytometry using the Aldefluor assay. DEAB was used to define the baseline of Aldefluor-positive fluorescence. (B) BT474 cells (5x10 4 cells/ml) were plated in ultra-low attachment dishes and cultured in the presence or absence of EBA for 5 days. The number and volume of mammospheres were measured by microscopy. (C) Overall survival of patients with breast cancer stratified by the co-expression of ALDH1A1 and CD44. (D) Spearman correlation analysis of ALDH1A1 and CD44 mRNA levels in patients with HER2-positive breast cancer from The Cancer Genome Atlas cohort (n=76). Kaplan-Meier survival analyses of patients with HER2-overexpressing breast cancer stratified by (E) ALDH1A1 and (F) CD44 expression. Patients were divided into high- and low-expression groups based on the median gene expression. Statistical significance was determined using the log-rank test. (G) JIMT-1 cells were treated with EBA (3 μ M) for 48 h and the CD44 high /CD24 low cell populations were identified by flow cytometry. (H) JIMT-1 cells (1.5x10 4 cells/ml) were cultured under serum-free suspension conditions in the presence of EBA (3 μ M) for 8 days. Mammosphere number and volumes were quantified. ** P<0.01 and **** P<0.0001 vs. vehicle-treated control (0 μ M EBA). EBA, ebastine; ALDH, aldehyde dehydrogenase; DEAB, diethylaminobenzaldehyde; CTL, control; ISO, isotype.
