Quercetin attenuates atherosclerosis via modulating oxidized LDL-induced endothelial cellular senescence

Project description:We have employed transcriptome microarray expression profiling as a discovery platform to figure out the pharmacological mechanisms of quercetin against endothelial senescence induced by ox-LDL in vitro. Expression of RCHY1, EIF4E1B, IGFBP3, SERPINE1, BRAF, SLC5A11 from this signature was quantified in the same kind of samples by real-time PCR, confirming the change pattern.

Expression data from ARPE-19 cells treated with LDL or ox-LDL

Project description:LDL or Ox-LDL 200ug/ml, which showed no loss of viability after a 48 hour exposure, induced a physiological and pathological transcriptional response, respectively. LDL induced a downregulation of genes associated with cholesterol biosynthesis while ox-LDL induced transcriptional alterations in genes related to inflammation, matrix expansion, lipid metabolism and processing, and apoptosis. Pentraxin-3 was secreted into the culture medium after RPE cells were stimulated with ox-LDL, and immunohistochemically evident in Bruchs membrane of human macular samples with age-related macular degeneration. ARPE-19 cells exposed to 200ug/ml ox-LDL had a 38% apoptosis rate compared to less than 1% when exposed to LDL or untreated controls (p<0.0001). While LDL induced a physiologic response by RPE cells, a pathological phenotypic response was seen after treatment with oxidatively modified LDL. The transcriptional, biochemical, and functional data provide initial support of a role for the hypothesis that modified LDLs are one trigger for initiating events that contribute to the development of age-related macular degeneration. Keywords: treatment with non-treatment control Human ARPE-19 cells were exposed to LDL or oxidatively modified LDL (ox-LDL) for 48 hours for RNA extraction and hybridization on Affymetrix microarrays. We sought to determine whether retina, pigment epithelial cells develop a pathologic phenotype after exposure to low density lipoproteins (LDL) that are oxidatively modified.We have made two comparsions: LDL treatment versus non-treatment; ox-LDL treatment versus non-treatment.

RNA-Sequencing Analysis of ox-LDL-treated Peritoneal Macrophages Transcriptomes

Project description:Since previous stduies demostrated that oxidized phospholipids function as caspase-11 agonists to induce noncanonical inflammasome activation in immune cells and the levels of oxidized phospholipids derived from ox-LDL are largely elevated in atherosclerotic lesions. Purpose:RNA-Sequencing analysis of ox-LDL-treated peritoneal macrophages transcriptomes.Methods and results:The principal component analysis gene expression profiles of the control and ox-LDL-treated groups were clearly distinct. Among the DEGs that met the cutoff criteria of a -log10(false discovery rate (FDR)) > 2 and |log2(fold change (FC)| > 2. A total of 1,388 downregulated and 855 upregulated genes were identified. GSEA showed that the dominant upregulated pathways in ox-LDL-treated macrophages were associated with the IL-1-mediated signaling pathway, response to cytokine stimulus, and granulocyte migrationwe discovered that caspase-11-mediated inflammation signaling was significantly activated in ox-LDL-treated peritoneal macrophages.Conclusions：we verified caspase11associated inflammatory signaling was significantly activated in ox-LDL-treated macrophages.

Expression data of human vascular smooth muscle cells (hVSMC) in response to n-LDL and ox-LDL.

Project description:Early transcriptomic response to n-LDL and ox-LDL in human vascular smooth muscle cells (hVSMC). We used microarrays with the aim of assessing early molecular changes that induce a response in the VSMC using native and oxidized low-density lipoprotein (n-LDL and ox-LDL).

Expression data from bladder cancer cells T24 treated with ox-LDL or vehicle

Project description:Target genes regulated by ox-LDL treatment in bladder cancer cells T24 were identified by microarrays. In this dataset, we include the expression data obtained from bladder cancer cells T24 starved with serum-free medium and then treated with 20 μg/mL ox-LDL or vehicle for 24 h. These data are used to obtain genes that are differentially expressed in response to ox-LDL treatment.
