Figure 2. Trafficking of isotopically labeled saturated and monounsaturated fatty acids into the major classes of phospholipids in HEK293 cells expressing FATP2 (FATP2 OE).

Figure 2

FATP2 OE or control cells were labeled individually (50µM) with 13C16:0, or 13C18:1 for 4h, and isotopically labeled phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatidylserine (PS) determined using ESI/MS as detailed under “Experimental Procedures;” C16:0 (A), C18:0 (B), and C18:1 (C). The error bars represent the standard error of the mean (n=4). *, p ≤ 0.05 relative to the vector control (paired t test).
