Antiproliferative effects of γ-tocotrienol, erlotinib, gefitinib, and trastuzumab on neoplastic +SA mammary epithelial cell growth. Cells were plated at a density of 5 × 104 cells per well (6 replicates/group) in 24-well plates and exposed to their respective treatments for a 4-day period. Viable cell number was determined by MTT colorimetric assay and indicated as percentage of control. Each bar represents the mean ± SEM in each treatment group and is representative of three independent experiments. *P < 0.05 as compared to the vehicle treated controls.
