“…Another research by Liang et al 26 identified the lncRNA 2810403D21Rik/Mirf can act as a ceRNA of miRNA26a in ischemic myocardial injury. The lncRNA TNK-AS1 regulates smooth muscle cell proliferation and migration via acting as a ceRNA of miR-150-5p 27 . The uncovering of the ceRNA mechanism may provide a new layer for exploring the physiopathology process and shed new light on cardiovascular research.…”

Epicardial adipose tissue (EAT) contributes to the pathophysiological process of coronary artery disease (CAD). The expression profiles of long non-coding RNAs (lncRNA) in EAT of patients with CAD have not been well characterized. We conducted high-throughput RNA sequencing to analyze the expression profiles of lncRNA in EAT of patients with CAD compared to patients without CAD. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were executed to investigate the principal functions of the significantly dysregulated mRNAs. We confirmed a dysregulated intergenic lncRNA (lincRNA) (LINC00968) by real-time quantitative PCR (RT-qPCR). Subsequently, we constructed a ceRNA network associated with LINC00968, which included 49 mRNAs. Compared with the control group, lncRNAs and genes of EAT in CAD were characterized as metabolic active and pro-inflammatory profiles. The sequencing analysis detected 2539 known and 1719 novel lncRNAs. Then, we depicted both lncRNA and gene signatures of EAT in CAD, featuring dysregulation of genes involved in metabolism, nuclear receptor transcriptional activity, antigen presentation, chemokine signaling, and inflammation. Finally, we identified a ceRNA network as candidate modulator in EAT and its potential role in CAD. We showed the expression profiles of specific EAT lncRNA and mRNA in CAD, and a selected non-coding associated ceRNA regulatory network, which taken together, may contribute to a better understanding of CAD mechanism and provide potential therapeutic targets.Trial registration Chinese Clinical Trial Registry, No. ChiCTR1900024782.

“…[36][37][38][39][40] However, report also indicates that ox-LDL can enhance cell proliferation in human aortic smooth muscle cells or Endothelial cell at a relatively low concentration. [41][42][43][44] This difference might be due to cell performance differs to cell type when expose to ox-LDL. Additionally, Zhu et al suggest that ox-LDL plays dual effect on inflammatory response by triggering LOX-1/PPARγ pathway.…”

These authors contributed equally to this workObjective: This study was to investigate the mechanism of inflammatory pathology modification induced by ox-LDL in endothelial cells. Methodology: In this study, we firstly investigated the efflux of cholesterol of endothelial cells under the treatment of ox-LDL, and cell proliferation, ROS production, cell apoptosis was measured. Further, proteins of ASK1, NLRP3 inflammasomes and endoplasmic reticulum stress response were detected. Afterwards, ASK1 inhibitor (GS-4997) or endoplasmic reticulum stress (ERS) inhibitor (4-PBA) was used to measure the performance of endothelial cells. Results: In this study, endothelial cells were treated with ox-LDLs alone or in combination with a GS-4997 or 4-PBA. Results showed that ox-LDLs attenuated the efflux of cholesterol from endothelial cells in a dose-dependent manner. Ox-LDLs inhibited the proliferation of endothelial cells, and induced their apoptosis and production of reactive oxygen species (ROS). Additionally, ox-LDLs upregulated the levels of phosphorylated ASK1, ERS-related proteins (chop, p-PERK, GRP78, and p-IRE-1), and inflammation-associated proteins (NLRP3, IL-1β, and caspase 1) in endothelial cells. Moreover, we proved that GS-4997 could partly reverse ox-LDL-mediated cell proliferation, apoptosis, ROS production, and inflammation in endothelial cells, and increase cholesterol efflux. We also found that 4-PBA could attenuate the effects of ox-LDLs on endothelial cell cholesterol efflux, proliferation, apoptosis, ROS production, and inflammation. Conclusion: Our results suggest that cholesterol efflux from endothelial cells is reduced by ox-LDLs, and these reductions in cholesterol efflux are accompanied by increased NLRP3 inflammasome signaling, ASK1 and higher levels of endoplasmic reticulum stress. Our results suggest this axis as potential targets for treating atherosclerosis.

“…In recent years, the upstream mechanism of FGF1 dysregulation in VSMCs has been gradually elucidated. For example, in ox-LDL-treated human aortic smooth muscle cells (HASMCs), the overexpression of lncRNA TNK2-AS1 indirectly upregulates the expression levels of vascular endothelial growth factor A and FGF1 by inhibiting miR-150-5p, and thus enhances the proliferation and migration of HASMCs [ 22 ]. In this work, we found the expression of FGF1 in ox-LDL-stimulated VSMCs and carotid smooth muscle derived from ApoE −/− mice fed a high-fat diet was remarkably increased.…”

Background As one of the crucial causes leading to cardiovascular disease, atherosclerosis (AS) develops in association with the dysfunction of vascular smooth muscle cells (VSMCs). However, the associated mechanism of the proliferation and migration in VSMCs requires further elucidation. Material/Methods Human VSMCs and ApoE-knockout (ApoE −/− ) mice were used to establish AS cell and animal models, respectively. Expression levels of miR-188-3p and fibroblast growth factor 1 ( FGF1 ) mRNA were detected using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Western blot was used to assess FGF1 protein expression. The proliferation, migration, and apoptosis of the cells were determined using MTT, BrdU, and Transwell assays, as well as flow cytometry analysis. The interaction between miR-188-3p and FGF1 was validated using dual-luciferase reporter gene assay, qRT-PCR, and Western blot analysis. Results MiR-188-3p was found to be significantly decreased in the serum of AS patients and ApoE −/− mice as well as VSMCs of ApoE −/− mice and human VSMCs treated with oxidized low-density lipoprotein. MiR-188-3p repressed the proliferation and migration of VSMCs but promoted apoptosis of VSMCs. The binding site between miR-188-3p and 3′ untranslated region (3′-UTR) of FGF1 was identified, and FGF1 was verified as a target gene of miR-188-3p. Restoration of FGF1 reversed the effects of miR-188-3p on VSMCs. Conclusions MiR-188-3p suppresses the proliferation and migration of VSMCs and induces their apoptosis through targeting FGF1 .
