[14C]-OA incorporation into lipid classes after 2 and 390 min of incubation in undifferentiated FABP1 knockdown and control cells. Proliferating cells were incubated with 100 µM [14C]-OA with BSA for 2 (A) and 390 (B) min. Cell lipids were extracted and separated by TLC. Lipid spots were scraped, and their radioactivity quantified. Radioactivity incorporated in each lipid class is expressed as percentage of total radioactivity incorporated. CE, cholesteryl esters; TG, triacylglycerols; FFA, free fatty acids; DG, diacylglycerols; MG, monoacylglycerols; PL, total phospholipids. Results are means ± SEM, n=3, * P < 0.0167 versus control.
