Fig. 5. LCMS measurement of different lipid species and Myriocin effects in CF cells and in healthy (H) broncho epithelial cells. The content of different lipid species was analyzed by LC-MS. CF cells lipid content is higher than healthy in all the observed species; 24 hours Myr reduced the content of all the evaluated lipid species in CF cells: A, Ceramide (Cer); B, Sphingomyelin (SM); C, phosphatidylcholine (PC); D, phosphatidylethanolamine (PE); E, phosphatidylserine (PS); F, Lysophosphatidylcholine (LPC); G, lysophosphatidylethanolamine (LPE); H, triacylglycerols (TE); I, cholesterol esters (CE); L, free cholesterols (CF). Data are expressed as mean ± SE (* p<0.05; ** p<0.01); Anova followed by Bonferroni post-test.
