Quantitation of fatty acid species in lipid subclasses of LPA treated BV-2 cells. Serum starved BV-2 cells were incubated in the absence and presence of 1 µM LPA for the indicated times. (A) Quantitation of total FAs present in the indicated lipid species (PL, phospholipids; DG, diacylglycerols; FFA, free fatty acids; TAG, triacylglycerols; CE, cholesterylesters). Individual FA content in each lipid class: (B) Phospholipids, (C) diacylglycerols, (D) free fatty acids, (E) triacylglycerols, and (F) cholesterylesters. Data represent mean ± SEM of four independent experiments; * p < 0.05, ** p < 0.01, *** p < 0.001 compared to control; one-way ANOVA with Bonferroni correction).
