Опубликована: Март 20, 2022

Atherosclerosis is the main risk factor for cardiovascular disease (CVD), which leading cause of mortality worldwide. initiated by endothelium activation and, followed a cascade events (accumulation lipids, fibrous elements, and calcification), triggers vessel narrowing inflammatory pathways. The resultant atheroma plaque, along with these processes, results in complications. This review focuses on different stages atherosclerosis development, ranging from endothelial dysfunction to plaque rupture. In addition, post-transcriptional regulation modulation microRNAs lncRNAs, role microbiota, importance sex as crucial are covered here order provide global view disease.

The novel regulatory role of lncRNA‐miRNA‐mRNA axis in cardiovascular diseases

Journal of Cellular and Molecular Medicine, Год журнала: 2018, Номер 22(12), С. 5768 - 5775

Опубликована: Сен. 6, 2018

Long noncoding RNAs (lncRNAs) are longer than 200 nt in length that characterized by low levels of sequence conservation and expression; lncRNAs modulate various biological functions at epigenetic, transcriptional post-transcriptional levels, or directly regulate protein activity. As a family small evolutionarily conserved RNAs, microRNAs (miRNAs) capable regulating physiological pathological processes via inhibiting target mRNA translation promoting degradation. A number studies have confirmed both miRNAs closely associated with the development cardiovascular diseases (CVDs), such as cardiac remodelling, heart failure, myocardial injury arrhythmia, they act biomarkers, potential therapeutic targets strong indicators prognosis; however, underlying molecular mechanism has not been elucidated. Recently, emerging evidence showed novel regulatory crosstalk among lncRNAs, mRNAs plays pivotal role pathophysiological CVDs response to stress stimuli. In this review, I comprehensively summarized relationship highlighted important lncRNA-miRNA-mRNA axis CVDs.

Silencing Of Circular RNA-ZNF609 Ameliorates Vascular Endothelial Dysfunction

Theranostics, Год журнала: 2017, Номер 7(11), С. 2863 - 2877

Опубликована: Янв. 1, 2017

Vascular dysfunction is a hallmark of ischemic, cancer, and inflammatory diseases, contributing to disease progression. Circular RNAs (circRNAs) are endogenous non-coding RNAs, which have been reported be abnormally expressed in many human diseases. In this study, we used retinal vasculature determine the role circular RNA vascular dysfunction. We revealed that cZNF609 was significantly up-regulated upon high glucose hypoxia stress vivo vitro. silencing decreased vessel loss suppressed pathological angiogenesis vivo. increased endothelial cell migration tube formation, protected against oxidative By contrast, transgenic overexpression showed an opposite effects. acted as miR-615-5p sponge sequester inhibit activity, led MEF2A expression. could rescue silencing-mediated effects on migration, apoptosis. Moreover, dysregulated expression detected clinical samples patients with diabetes, hypertension, coronary artery disease. Intervention promising therapy for

H19 knockdown suppresses proliferation and induces apoptosis by regulating miR-148b/WNT/β-catenin in ox-LDL -stimulated vascular smooth muscle cells

Journal of Biomedical Science, Год журнала: 2018, Номер 25(1)

Long non-coding RNAs (lncRNAs) have been identified as critical regulators in the development of atherosclerosis (AS). Here, we focused on discussing roles and molecular mechanisms lncRNA H19 vascular smooth muscle cells (VSMCs) progression.RT-qPCR assay was used to detect expression patterns miR-148b clinical samples cells. Cell proliferative ability evaluated by CCK-8 colony formation assays. apoptotic capacity assessed cell percentage caspase-3 activity. Bioinformatics analysis, luciferase RNA immunoprecipitation (RIP) assays were employed demonstrate relationship among H19, wnt family member 1 (WNT1). Western blot performed determine expressions proliferating nuclear antigen (PCNA), ki-67, Bax, Bcl-2, WNT1, β-catenin, C-myc E-cadherin.The level increased decreased human AS patient serums oxidized low-density lipoprotein (ox-LDL)-stimulated aorta (HA-VSMCs). knockdown suppressed proliferation promoted apoptosis HA-VSMCs following treatment ox-LDL. inhibited direct interaction. Moreover, inhibitor could reverse effects depletion ox-LDL-stimulated HA-VSMCs. Further mechanical explorations showed that WNT1 a target acted competing endogenous (ceRNA) enhance expression. Furthermore, miR-148 exerted its pro-proliferation anti-apoptosis through activating WNT/β-catenin signaling HA-VSMCs.H19 facilitated modulating pathway via HA-VSMCs, implicating potential values therapy.

Linking a role of lncRNAs (long non-coding RNAs) with insulin resistance, accelerated senescence, and inflammation in patients with type 2 diabetes

Human Genomics, Год журнала: 2018, Номер 12(1)

Опубликована: Авг. 23, 2018

Studying epigenetics is expected to provide precious information on how environmental factors contribute type 2 diabetes mellitus (T2DM) at the genomic level. With progress of whole-genome resequencing efforts, it now known that 75-90% human genome was transcribed generate a series long non-coding RNAs (lncRNAs). While lncRNAs are gaining widespread attention as potential and robust biomarkers in genesis well progression several disease states, their clinical relevance regulatory mechanisms yet be explored field metabolic disorders including diabetes. Despite fact Asian Indians highly insulin resistant more prone develop T2DM associated vascular complications, there virtually lack data role setting. Therefore, we sought evaluate panel senescence-inflammation signatures peripheral blood mononuclear cells (PBMCs) from patients with (T2DM; n = 30) compared individuals normal glucose tolerance (NGT; 32).Compared control subjects, expression levels PBMCs showed significantly (p < 0.05) increased HOTAIR, MEG3, LET, MALAT1, MIAT, CDKN2BAS1/ANRIL, XIST, PANDA, GAS5, Linc-p21, ENST00000550337.1, PLUTO, NBR2. In contrast, lncRNA patterns THRIL SALRNA1 were decreased subjects. At transcriptional level, senescence markers (p53, p21, p16, β-galactosidase), proinflammatory (TNF-α, IL6, MCP1, IL1-β), epigenetic signature histone deacetylase-3 (HDAC3) elevated Interestingly, mRNA Sirt1 telomere length Majority altered positively correlated poor glycemic control, resistance, senescence, inflammation, HDAC3 negatively length. Logistic regression analysis revealed significant association T2DM, but this lost after adjusting for resistance (HOMA-IR) markers.Our study provides clinically relevant evidence accelerated cellular inflammation.

In review, we analyze various typical phenomena outcomes cellular pro-inflammatory stress atherosclerosis, as well role endothelial dysfunction local systemic manifestations low-grade inflammation. We also present features immune development productive stable unstable plaques, along their similarities differences compared There are numerous factors that act inducers inflammatory process including vascular endothelium aging, metabolic dysfunctions, autoimmune, some cases, infectious damage factors. Life-critical complications such cardiogenic shock severe strokes, associated acute hyperinflammation.
