    • 4 cells were suspended and grown for 24 h in 950 μl DMEM containing 10% (v/v) lipid-depleted serum. After a 3 h preincubation in the presence of inhibitor, labeled acetate (1 μCi/well) was added. After further 3 h incubation, the medium was removed and the cells were lysed with 500 μl of 0.1 N NaOH for 30 min. After saponification with 1.5 ml of 10% (w/v) methanolic KOH for 1 h at 80 °C, nonsaponifiable lipids were extracted with petroleum ether and separated on TLC plates (Alufolien Kieselgel 60F254, Merck, Darmstadt, Germany) using n-hexane/ethyl acetate (85:15 v/v) as a developing solvent and authentic standards of cholesterol, lanosterol, dioxidosqualene, oxidosqualene, and squalene as reference compounds. Radioactivity in separated bands was measured using a System 200 Imaging Scanner (Hewlett-Packard, Palo Alto, CA, USA).
