  1. Abbreviations: ER, endoplasmic reticulum; hMEC, human mammary epithelial cell line; HQBA, N-((8-hydroxy-7-quinolinyl) (4-methylphenyl)methyl)benzamide; LD50s, lethal dose 50 values; ND, assay not done.
  2. Cells were plated in clear 96-well plates at 5000 cells/well, allowed to adhere, and treated for 72 or 168 h with HQBA concentrations ranging from 20 μM to 9.8 nM. Data were processed in Prism and errors are derived from 95% confidence intervals.
