Figure 1From: Polyunsaturated fatty acid relatively decreases cholesterol content in THP-1 macrophage-derived foam cell: partly correlates with expression profile of CIDE and PAT membersCell viability of THP-1 macrophage after pre-treatment with different NEFAs at different concentrations for 72 hours. The THP-1-derived macrophages were pretreated by PA, OA, LA and EPA separately with time and dose gradients. The cell viability was determined by MTT colorimetric assay. Data represent mean ± SEM (n = 3).Back to article page
