Fig. 1. Lipid composition was not affected by Gag and Gag derivatives expression.
Total lipid fraction extracted from HeLa cells transfected with vectors or plasmids encoding the indicated Gag and Gag derivatives was separated in a solvent for polar lipids (a) or neutral lipids (c) as described in “Methods”. The bands corresponding to SM (a) and Chol (c) indicated by arrowheads on the right side of thin layer chromatography (TLC) plates were quantitated. The relative band intensity to the control (vectors) was shown as a mean ± SD for three independent experiments in (b) and (d). The values in each experiment were also shown in dots in three different blue. The differences were not significant (ns) among all samples at the significance level of 0.05 in one-way ANOVA post-hoc Tukey test. Band positions of phosphatidylcholine (PC), phosphatidylserine (PS), phosphatidylethanolamine (PE), and cholesteryl ester (CE) were indicated by arrowheads on the left side of TLC plates in (a) and (c). Vec, vectors; WT, Gag WT; ∆L, Gag-∆L; P99A, Gag-P99A; EE, Gag-EE; WM, Gag-WM. Source data and statistics for (b and d) were provided as a Source Data file.
