1For the drug and fatty acid toxicity assays, cells were cultured in media supplemented with graded concentrations of araC or the fatty acids for 24 hrs. For the fatty acid supplemented drug toxicity assays, cells were treated with 3 μM DHA or AA for 24 hrs. Cells were then cultured in media supplemented with DHA or AA and graded concentrations of araC for an additional 24 hrs. Values are means ± SEM with sample sizes indicated in parenthesis. Values followed by * are significantly different from the values within the same column (p < 0.05).
