Figure Lengend Snippet: Electrophoresis of rHDL containing each policosanol (PCL) after synthesis with palmitoyloleoyl-phosphatidylcholine (POPC), free cholesterol (FC), and apolipoprotein A-I (apoA-I). The molar ratio of POPC:FC:apoA-I:PCL = 95:5:1:1. ( A ) Native electrophoresis of each rHDL under a non-denatured state on 0.6% agarose (15 μg of protein/lane) to compare electromobility depending on the three three-dimensional structures of apoA-I/HDL and its negative charge. The apoA-I in rHDL was also visualized via Coomassie brilliant blue staining (final 1.25%). The red and black arrowheads indicate the band position of rHDL-0 and rHDL-1, respectively. ( B ) Electrophoretic patterns of each rHDL in a denatured state on 14% SDS-PAGE (5 μg of protein/lane). The black arrowhead indicates phospholipid (PL) and policosanol (PCL) debris. Lane M, molecular weight marker (Bio-Rad 161-0374, precision plus protein standards). Lane A, lipid-free apoA-I—lane 0, rHDL alone; lane 1, rHDL containing PCL-1; lane 2, rHDL containing PCL-2. The gel was subjected to staining with Coomassie brilliant blue (0.125%) to facilitate visualization of apoA-I and phospholipids.

Figure Lengend Snippet: Comparative antioxidant potential of rHDL-containing policosanol to prevent cupric-ion-mediate oxidative damage of LDL. ( A ) Electrophoresis of LDL (10 μg of protein) treated with rHDL (0.5 μg of protein) comprising different origins of policosanols in 0.5% agarose gel using Tris-EDTA buffer (pH 8.0) at 50 V for 1 h. The separated bands of the apo-B fraction of LDL were stained using Coomassie brilliant blue (final 1.25%). The band positions of native LDL and oxidized LDL are indicated by a blue arrowhead and a red arrowhead, respectively. Lane N, native LDL; lane O, oxidized LDL (LDL + Cu 2+ ); lane 0, LDL + Cu 2+ + rHDL-0; lane 1, LDL + Cu 2+ + rHDL-1; lane 2, LDL + Cu 2+ + rHDL-2. ( B ) Quantification of thiobarbituric acid reactive substances (TBARS) in LDL challenged with cupric ion and subsequently treated with rHDL comprising policosanol. The values are represented as malondialdehyde (MDA, μM) in LDL using the MDA standard. The values in the bar graph represent the mean ± SD of three independent experiments. A pairwise statistical difference was established using a t -test by comparing the results with the ox-LDL value. *, p < 0.05 versus ox-LDL; **, p < 0.01 versus ox-LDL; ns, no significant.
