Research Plateforms

A. Flowchart for isolating atherogenic lipoproteins

1. Purifications for VLDL, LDL, and HDL: Blood samples to be used for VLDL, LDL and HDL isolation will be obtained from subjects as described in each sub-project. After the initial screening, blood samples will be removed from the subjects with precaution to avoid coagulation and ex vivo oxidation. The plasma will be treated with Complete Protease Inhibitor Cocktail (Roche; Cat. No. 05056489001; 1 tablet/100 mL) to prevent protein degradation. Lipoprotein preparation from the human. Overlay the plasma with 2 mL of Milli-Q water and spin at 20,000 rpm for 2 hours. Remove upper white fraction, chylomicrons, and save the remnant layer which contains VLDL, IDL, LDL, and HDL for a series of isolation steps. To progressively separate VLDL (d=0.93–1.006), IDL (d=1.006–1.019), LDL (1.019 to 1.063 g/dL) and HDL (1.063 to 1.210 g/dL) from one another, the remnant sample will be sequentially adjusted to d=1.006, d=1.019, d=1.063, d=1.210 respectively, by adding potassium bromide and followed by centrifugation at 45,000 rpm for 20 hrs at 4°C. After centrifugation at each isolation step, IDL will be discarded whist VLDL, LDL and HDL will be collected. Isolated VLDL, LDL and HDL samples will be treated with 5 mM EDTA and nitrogen to avoid ex vivo oxidation. Then, VLDL, LDL and HDL samples will be dialyzed against buffer A (20 M, pH8.0, 0.5 M EDTA) for 24 hours (×3 times) to remove excessive potassium bromide, and will be filtrated through a 0.22-µm filter (Sartorius; Minisart®) to sterilize the samples.
2. VLDL, LDL, and HDL subfractions: Approximately 30 mg of VLDL or LDL material will be injected onto a UnoQ12 anion-exchange column (BioRad) by using the ÄKTA fast-protein liquid chromatography (FPLC) pump (GE Healthcare Life Sciences, Pittsburgh, PA). VLDL or LDL will be eluted according to electronegativity by the use of a multistep gradient of buffer B (1 mol/L NaCl in buffer A) at a flow rate of 2 mL/min. In short, samples will be equilibrated with buffer A for 10 mins, following by linearly increase to 15% buffer B in 10 mins (fraction 1), linearly increase to 20% buffer B in 30 mins (fraction 2, 3), keep at 20% buffer B for 10 mins (fraction 4) and linearly increase to100% buffer B in 20 mins (fraction 5). Lastly, the effluents will be monitored at 280 nm.
   Purification of fractionated VLDL, LDL and HDL: Based on the gradient profile, each VLDL/LDL fractions will be pooled. The volume of each subfraction is constant. Dilution of VLDL/LDL during chromatography depends on the injection volume. The respective fractions will be concentrated with Centriprep® filters (YM-30; EMD Millipore Corp., Billerica, MA), be dialyzed against buffer A (20 M, pH8.0, 0.5 M EDTA) for 24 hours (3 days) and be sterilized by passing through 0.22-μm filters (Sartorius; Minisart®). The isolated fractions will be quantified at their protein concentrations by the Lowry method and then be stored at 4°C.
3. Apoptosis Measurements: Endothelial cells, renal cells are used after 3 or 4 passages and maintained in DMEM (Invitrogen) containing 10% FBS. During treatment, FBS reduced to 5% in DMEM. 1×104 cells are seeded in 96-well plate for 24 hours, subconfluent cultures f cultured cells are exposed to PBS (lipoprotein-free, negative control) or graded (25, 50, and 100 μg/mL) LDL subfractions, unfractionated normolipidemic LDL, and for 24 hours. Apoptosis is assessed with visualization by a Zeiss Axiovert 200 fluorescence microscope and filters to capture digital images based on Hoechst 33342, propidium iodide (red), and calcein AM (green) staining of nuclear, apoptotic DNA membrane integrity. Cytoplasmic histone-associated DNA fragmentation is examined by using the Cell Death Detection ELISA Assay (Roche) according to the protocol of the manufacturer.

B. Flowchart for studying proteomics and Lipidomics

1. 2-Dimensional electrophoresis: Protein contents of VLDL/LDL/HDL subfractions will be analyzed by 2-dimensional electrophoresis. Twice delipidated (1:1 EtAc+EtOH, 0.3 mL/30 μg LDL protein) VLDL/LDL/HDL particles will be centrifuged for 30 min (14000 rpm, 4°C). After removal of the solution, the lipoprotein pellet will be resuspended in 30 μL H2O. Resuspended samples will be incubated in ZOOM IPGRunner Cassette with Strip, 1X ZOOM 2D Protein Solubilizer 1, 1X Protease Inhibitor Cocktail, 20 mM DTT, and 3.5 mM Tris base at pH 7.4 for 2 hours. Two-dimensional-PAGE (isoelectrofocusing, equilibrating, performing) will be performed by ZOOM IPGRunner, ZOOM Equilibration Tray, and XCell SureLock Mini-Cel according to the user manual. The 4–20% 2-dimensional gels will be stained with SYPRO Ruby Protein Gel Stain (Ex/Em: 280, 450/610 nm).
2. LC/MSE analysis for protein composition: Proteins in each VLDL/LDL/HDL subfractions will be quantified by data-independent parallel-fragmentation mass spectrometry (LC/MSE), a Waters Xevo G2 Q-TOF mass spectrometer equipped with a nano-electrospray ionization (ESI) interface (Waters Corporation, MA, USA) and ProgenesisTM QI-P software (Nonlinear Dynamics, USA). Total proteins from HDL will be digested with trypsin, and be separated on a M-class ultra-performance liquid chromatography (UPLC; Waters Corporation, MA, USA). A 50 fmol-on-column tryptic digest of yeast alcohol dehydrogenase will be used as the internal standard. Peptide elution will be executed through a 75 μm × 25 cm BEH C-18 column under gradient conditions at a flow rate of 300 nL/min over 70 min at 35°C. The mobile phase will be composed of acetonitrile as the organic modifier and formic acid (0.1% v/v) for molecule protonation. Parallel ion fragmentation will be programmed to switch between low (4 eV) and high (15–45 eV) energies in the collision cell, and data will be collected from 50 to 2000 m/z utilizing glu-fibrinopeptide B (Sigma Aldrich, m/z 785.8426) as the separate data channel lock mass calibrant. Data will be processed with ProgenesisTM QI-P for relative quantification. In addition, the ProteinLynx Global Server v2.5 (Waters) will be further used to search for possible modifications. Deisotoped results will be searched for protein association from the UniProt (www.uniprot.org) human protein database.
3. LC/MSE analysis for lipid composition: Total lipids from each subfraction of HDL will be quantified by LC/MSE and ProgenesisTM QI software. Different from a proteomic approach, an ACQUITY UPLC I-Class System equipped with CSHTM 1.7 um, 2.1 mm × 10 cm C-18 column and a flow rate of 400 uL/min over 18 min at 55°C will be used for lipidomic studies. The mobile phase A will be composed of 10mM NH4HCO2 in ACN/H2O (60/40) and 0.1% formic acid (0.1% v/v), mobile phase B will be composed of 10mM NH4HCO2 in IPA/ACN (90/10) and 0.1% formic acid (0.1% v/v) for molecule protonation. Mass spectrometry will be performed on Xevo G2 Q-Tof (Waters) instrument equipped with a low flow electrospray ionization probe (Waters) interface and operated in the data-independent collection mode (MSE). Parallel ion fragmentation will be programmed to switch between low (4 eV) and high (35–55 eV) energies in the collision cell, and data will be collected from 200 to 1600 m/z utilizing leucine (Sigma Aldrich, m/z 556.2771) as the separate data channel lock mass calibrant. Data will be processed with MarkerLynx (Waters) and ProgenesisTM QI software.

 

Recent Research

1. Enhanced sphingomyelinase activity in apolipoprotein B100 contributes to the atherogenicity of electronegative LDL. J Med Chem. 2016 Feb 11;59(3):1032-40. 

Sphingomyelinase (SMase) catalyzes the degradation of sphingomyelin to ceramide. In patients with metabolic syndrome or diabetes, circulating plasma ceramide levels are significantly higher than in normal individuals. Our data indicate that electronegative low-density lipoprotein (LDL) shows SMase activity, which leads to increased ceramide levels that can produce pro-inflammatory effects and susceptibility to aggregation. According to sequence alignment and protein structure predictions, the putative catalytic site of SMase activity is in the α2 region of apoB-100. To identify specific post-translational modifications of apoB100 near the catalytic region, we performed data-independent, parallel-fragmentation liquid chromatography/mass spectrometry (LC/MSE), followed by data analysis with ProteinLynx GlobalServer v2.4. Results showed that the serine of apoB100 in electronegative LDL was highly O-glycosylated, including S1732, S1959, S2378, S2408 and S2429. These findings may support the changing of α-helix/β-pleated sheets ratio in protein structure analysis. Further study is necessary to confirm the activation of SMase activity by electronegative LDL.

 

2. The Underlying Chemistry of Electronegative LDL's Atherogenicity. (First author). Curr Atheroscler Rep. 2014 Aug;16(8):428) 

Electronegative low-density lipoprotein (LDL) found in human plasma is highly atherogenic and is elevated in individuals with increased cardiovascular risk. In this review, we summarize the available data regarding the elevation of electronegative LDL in the plasma of patients with various diseases. In addition, we discuss the harmful effects and underlying mechanisms of electronegative LDL in various cell types. We also highlight the known biochemical properties of electronegative LDL that may contribute to its atherogenic functions, including its lipid and protein composition, enzymatic activities, and structural features. Given the increasing recognition of electronegative LDL as a potential biomarker and therapeutic target for the prevention of cardiovascular disease, key future goals include the development of a standard methodology for the detection of electronegative LDL that can be used in a large-scale population survey and the identification and testing of strategies for eliminating electronegative LDL from the blood.

 

3. Highly electronegative LDL from patients with ST-elevation myocardial infarction triggers platelet activation and aggregation. (Blood. 2013;122:3632-3641). 

We provide evidence that plasma levels of L5—the most electronegative and atherogenic subfraction of low-density lipoprotein—are drastically elevated in patients with ST-elevation myocardial infarction (STEMI). Furthermore, we show that when L5 isolated from the plasma of STEMI patients was injected into the tail vein of mice, it induced platelet activation and shortened the tail-bleeding time. These results indicate that L5 is prothrombotic, which was further demonstrated by the ability of L5 to increase tissue factor and P-selectin expression on endothelial cells, enhance platelet aggregation, and promote platelet–endothelial cell interactions. We also showed that L5 enhanced ADP-induced platelet activation through the PAFR- and LOX-1–mediated PKCα signaling pathway. Our findings strongly suggest that L5 may be a key factor in promoting acute thrombosis that leads to STEMI.

 

4. Chemical composition-oriented receptor selectivity of L5, a naturally occurring atherogenic low-density lipoprotein. (Pure Appl Chem. 2011;83(9). 

Analysis with SDS-PAGE and 2-dimensional electrophoresis showed that the protein framework of L1 was composed mainly of apolipoprotein (apo) B100, with an isoelectric point (pI) of 6.620. There was a progressively increased association of additional proteins, including apoE (pI 5.5), apoAI (pI 5.4), apoCIII (pI 5.1), and apo(a) (pI 5.5), from L1 to L5. LC/MSE was used to quantify protein distribution in all subfractions. On the basis of weight percentages, L1 contained 99% apoB-100 and trace amounts of other proteins. In contrast, L5 contained 60% apoB100 and substantially increased amounts of apo(a), apoE, apoAI, and apoCIII. The compositional characteristics contribute to L5's electronegativity, rendering it unrecognizable by LDLR. Thus, the chemical composition-oriented receptor selectivity hinders normal metabolism of L5, enhancing its atherogenicity through LOX-1.

 

5. Vascular progenitor cells in diabetes mellitus: roles of Wnt signaling and negatively charged low-density lipoprotein. (Chen CH, Dixon RA, Ke LY, Willerson JT. Circ Res. 2009 May 8;104(9):1038) 

Expression of miR-8 potently antagonizes Wnt signaling, both by inhibiting Wnt-Fz interaction on the plasma membrane and by reducing TCF protein intracellularly. Additionally, miR-15a and miR-16-1 can also antagonize Wnt signaling, and reduction of these microRNAs promotes growth of prostate cancer cells. Thus, the role of Wnt signaling in EC or vascular PC activity is not totally clear at this time, and uncontrolled stimulation of this pathway may invite dangerous consequences. These considerations, including how L5 may counteract the CD133+ PC and Wnt interactions, are schematically summarized in the Figure.
