Figure 1: Depletion of GSLs from cultured ECV304 cells with sphingolipids synthesis inhibitors: Cellswere treated in serum-free medium for 48 h. GSLs were extracted, purified and analyzed by high performance thin layer chromatography as described in the Methods section. A. A representative thin layer chromatography (TLC) plate of ECV304 cells treated with Et-DOP4, FB1 and myriocin at the indicated concentrations.
