Apolipoprotein A1 (APOA1), the major protein of high-density lipoprotein (HDL), contains 10 helical repeats that play key roles in protein-protein and protein-lipid interactions. The current structural model for HDL proposes that APOA1 forms an antiparallel dimer in which helix 5 in monomer 1 associates with helix 5 in monomer 2 along a left-left (LL5/5) interface, forming a protein complex with a 2-fold axis of symmetry centered on helix 5. However, computational studies suggest that other orie ...[more]

Project description:HDL proteome dynamics may determine HDL cardioprotective functions. We aimed to characterize proteome and lipid profiles in small, medium and large (S/M/L) HDL fractions and analyze their functions. We characterized mouse HDL fractions by their high phospholipid (PL) content and collected S/M/L-HDLsubfractions by using fast protein liquid chromatography. The pooled S/L/M-HDL elution was subjected to mass spectrometry (MS) analysis using a Qstar XL-MS system, performing HDL subpopulation proteomic analysis. Fifty-one HDL proteins (39 in S-HDL, 27 in M-HDL and 29 in L-HDL) were identified and grouped into 4 functional categories (5 in lipid metabolism, 24 in immune response, 7 in coagulation, and 14 others). There were 16, 3 and 7 proteins present in only the S-HDL, M-HDL and L-HDL subfractions, respectively, and 11 proteins overlapped in all S/M/L-HDL subfractions. The dynamic changes in relative HDL protein levels were then characterized based on their functional groups by biological and bioinformatical methods.

Project description:In this study, murine primary aortic smooth muscle cells (SMCs) were transcriptionally profiled at baseline, after 3 d of cholesterol loading, and after 3 d of subsequent cholesterol unloading with HDL treatment, to identify vascular SMC genes that are transcripionally dysregulated in response to cholesterol loading and/or unloading. Mouse aortic SMCs were isolated from thoracic aortas of 8 week-old C57BL/6 mice (as described in Rong et al., Proc Nat Acad Sci USA, v100, pp13531M-bM-^@M-^S13536, 2003) and subconfluent cell preparations were harvested and transcriptionally profiled (baseline group) or treated with 10 M-NM-<g/mL cholesterol:methyl-M-NM-2-cyclodextrin complex (1:6 molar ratio) for 72 h for cholesterol loading. Of the cholesterol-loaded cells, samples were transcriptionally profiled (cholesterol samples) or treated for an additional 72 h with 100 M-NM-<g/mL human HDL and then transcriptionally profiled (HDL treatment). For all transcriptional profiling, RNA was isolated from cells using TRIzol, and labeled aRNA was prepared for hybridization to Affymetrix Mouse Genome 430 2.0 microarrays according to the manufacturer's protocol. Probe-level intensities were background-adjusted and normalized (in two separate analyses, one with baseline and cholesterol-treated samples, and the other analysis with all three sample groups) using Robust Multichip Average and combined into probesets using probe-to-probeset mappings from the University of Michigan CustomCDF project based on Ensembl Gene identifiers (release 59). Using the data from the analysis that combined the baseline and cholesterol-loaded samples, log2 probeset intensities were compared the between baseline and cholesterol sample groups using a one-way ANOVA with a P value cutoff determined by a Benjamini-Hochberg false discovery rate threshold of 0.05. Analysis (I): baseline and cholesterol-treated sample groups. Analysis (II): all three sample groups.

Project description:High-density lipoproteins (HDLs) protect pancreatic β cells against apoptosis. This property might be related to the increased risk to develop diabetes in patients with low HDL blood levels. However, the mechanisms by which HDLs protect β cells are poorly characterized. Here we use a transcriptomic approach to identify genes differentially modulated by HDLs in β cells subjected to apoptotic stimuli.

Project description:Circulating microRNAs (miRNA) are relatively stable in plasma and are a new class of disease biomarkers. Here we present evidence that human high-density lipoprotein (HDL) transports endogenous miRNAs and delivers them to recipient cells with functional targeting capabilities. Highly-purified fractions of human HDL contain small RNAs, and the HDL-miRNA profile from normal subjects is significantly different than familial hypercholesterolemia subjects. miRNAs were demonstrated to associate with both native and reconstituted HDL particles, and reconstituted HDL injected into mice retrieved distinct miRNA profiles from normal and atherogenic models. Cellular export of miRNAs to HDL was demonstrated to be regulated by neutral sphingomyelinase. HDL-mediated delivery of miRNAs to recipient cells was demonstrated to be scavenger receptor BI-dependent. Furthermore, HDL delivery of both exogenous and endogenous miRNAs resulted in the direct targeting of mRNA reporters. Notably, HDL-miRNA from atherosclerotic subjects induced differential gene expression, with significant loss of conserved mRNA targets in cultured hepatocytes. Collectively, these observations suggest that HDL participates in a novel mechanism of intercellular communication involving the transport and delivery of miRNAs.

Project description:Multiple studies to date have shown that high-density lipoprotein (HDL) levels are reduced in patients with coronavirus disease 2019 (COVID-19), and that the extent of this reduction is associated with poor clinical outcomes. While lipoproteins are known to play a key role during the lifecycle of hepatitis C virus, the direct influence they have upon coronavirus (CoV) infections remains poorly understood. In this study we utilise cross-linking mass spectrometry (XL-MS) to determine circulating protein interactors of the severe acute respiratory syndrome (SARS)-CoV-2 spike glycoprotein. Spike was revealed to interact with HDL, through direct interactions with apolipoprotein (Apo)-A1, ApoC3 and ApoD, highlighting multiple modalities of how SARS-CoV-2 and HDL may interact. XL-MS of plasma isolated from COVID-19 patients uncovered HDL protein interaction networks, dominated by acute phase serum amyloid proteins (SAA), whereby serum amyloid A2 (SAA2) was shown to bind to ApoD. ApoD was confirmed to also interact with core apolipoproteins of both LDL and VLDL, suggesting that SARS-CoV-2 may bind multiple lipoprotein species. The interaction between ApoD and spike was further validated in cells using immunoprecipitation-MS, which uncovered a novel interaction between both ApoD and spike with membrane-associated progesterone receptor component 1 (PGRMC1). Mechanistically, XL-MS coupled with data-driven structural modelling determined that ApoD may interact within the receptor-binding domain (RBD) of spike, posing the hypothesis that ApoD may interfere with binding to the angiotensin-converting enzyme 2 (ACE2) receptor. However, utilising multiple cell-based assays we determined ApoD to have no effect upon viral replication or infectivity.
