FA ID: fatty-acid identification; RESV: resveratrol; R.T.: retention time; ND: Not determined. ^aFatty acid detected in only one independent experiment. MCF-7 and MDA-MB-231 (1 × 10⁷) cells after resveratrol (80 and 200 μM, respectively) or DMSO 0.1% (control) treatment for 24 h were subjected to lipid extraction. Lipid extracts were analyzed by GC/MS. Results are expressed as mean ± S.E.M., n = 2.
