MIAT knockdown suppressed cell proliferation, migration, and invasion in ox-LDL-stimulated VSMCs. MIAT acted as a sponge of miR-490-3p, and miR-490-3p deficiency overturned the inhibition of MIAT knockdown on VSMC proliferation, migration, and invasion. ICAM1 was a direct target of miR-490-3p, and ICAM1 silencing repressed the proliferation, migration, and invasion of ox-LDL-stimulated VSMCs. Moreover, ICAM1 overexpression reversed the impacts of MIAT knockdown on ox-LDL-induced VSMC proliferation, migration, and invasion. MIAT knockdown could depress cell proliferation, migration, and invasion through miR-490-3p/ICAM1 axis in ox-LDL-induced VSMCs.In the present study, the role and molecular mechanism of long noncoding RNA CDKN2B-AS1 in human thoracic aortic dissection (TAD), a highly lethal cardiovascular disease, was investigated. The expression of CDKN2B-AS1 in human TAD and normal aortic tissues of donors were examined by quantitative real-time polymerase chain reaction. RNA pull-down assay and a series of luciferase reporter assays were performed to predict the relationships between CDKN2B-AS1, miR-320d, and STAT3. Cell counting kit 8 (CCK-8), TUNEL, and western blot assays were applied to validate the biological functions of CDKN2B-AS1 in rat aortic vascular smooth muscle cells. Results showed that CDKN2B-AS1 was expressed at a higher level in human TAD than in normal aortic tissues. CDKN2B-AS1 overexpression significantly promoted apoptosis and suppressed the proliferation of vascular smooth muscle cells. CDKN2B-AS1 silence exhibited the opposite effects. Mechanistically, CDKN2B-AS1 was identified as a molecular sponge for miR-320d and positively modulated STAT3 expression via repressing miR-320d. In conclusion, our study revealed that CDKN2B-AS1 was dysregulated and displayed multiple potential functions in human TAD. These findings suggested that CDKN2B-AS1 was a novel potential therapeutic target for human TAD.Newer generation drug eluting stents (DES) and pharmacotherapy have decreased thrombotic events post-percutaneous coronary intervention (PCI). There is lack of wide-ranging safety and efficacy evaluation in both stable ischemic heart disease and acute coronary syndrome in short-term (3-6 months) versus Standard-term (12 months) dual antiplatelet therapy (DAPT). We searched electronic databases using specific terms to identify randomized control trials comparing different durations of DAPT after PCI with DES. The outcomes of interest included all-cause mortality, myocardial infarction, stent thrombosis, major bleeding, target lesion and vessel revascularization, and stroke at follow-up duration ≥12 months post index PCI. Studies that compared DAPT less then 3 months or DAPT ≥12 months were excluded. Thirteen randomized control trials (n = 31,831) were included; 8401 patients received DAPT for 3 months and 7482 patients received DAPT in the 6 months group. Major bleeding rate was lower in the short-term (3-6 months) versus Standard-term (12 months) group (risk ratio 0.66; 95% confidence interval, 0.52-0.84, P less then 0.05). Repeat revascularization rate was higher in the short-term (3-6 months) versus Standard-term (12 months) (risk ratio 1.17; 95% confidence interval, 1.01-1.36, P less then 0.05) of DAPT duration after PCI with DES. No difference in other outcomes were observed when comparing short versus standard duration of DAPT in both stable ischemic heart disease and acute coronary syndrome.Myocardial ischemia is a common reason that causes human death globally. Long noncoding RNA taurine upregulated 1 (TUG1) serves as an oncogene in a variety of cancers. In this article, we aimed to investigate the role of TUG1 and its underlying signal pathway in hypoxia-induced myocardial cell injury. Cell viability, apoptosis, and lactate dehydrogenase (LDH) release were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, flow cytometry, western blot assay, and LDH cytotoxicity assay. Quantitative real-time polymerase chain reaction was applied to measure the enrichment of TUG1 and miR-29a-3p. MiR-29a-3p was predicted as a target of TUG1 by StarBase bioinformatic software, and the target relationship between TUG1 and miR-29a-3p was verified by dual-luciferase reporter assay. Hypoxia treatment induced the apoptosis and LDH release while inhibited the viability of AC16 cells. TUG1 was markedly upregulated while the level of miR-29a-3p was notably decreased in hypoxia-stimulated AC16 cells. learn more TUG1 contributed to hypoxia-induced AC16 injury. MiR-29a-3p depletion intensified hypoxia-induced AC16 damage. TUG1 negatively regulated the expression of miR-29a-3p through their direct interaction in AC16 cells. TUG1 silencing-mediated influences in hypoxia-induced AC16 cells were partly reversed by the interference of miR-29a-3p. In conclusion, TUG1 accelerated hypoxia-induced AC16 injury through inversely modulating the level of miR-29a-3p. TUG1/miR-29a-3p axis might be an underlying therapeutic target for myocardial ischemia.The most common complications in patients with type-2 diabetes are hyperglycemia and hyperlipidemia that can lead to cardiovascular disease. Alleviation of these complications constitutes the major therapeutic approach for the treatment of diabetes mellitus. Agonists of peroxisome proliferator-activated receptor (PPAR) alpha and PPARγ are used for the treatment of hyperlipidemia and hyperglycemia, respectively. PPARs belong to the nuclear receptors superfamily and regulate fatty acid metabolism. PPARα ligands, such as fibrates, reduce circulating triglyceride levels, and PPARγ agonists, such as thiazolidinediones, improve insulin sensitivity. Dual-PPARα/γ agonists (glitazars) were developed to combine the beneficial effects of PPARα and PPARγ agonism. Although they improved metabolic parameters, they paradoxically aggravated congestive heart failure in patients with type-2 diabetes via mechanisms that remain elusive. Many of the glitazars, such as muraglitazar, tesaglitazar, and aleglitazar, were abandoned in phase-III clinical trials. The objective of this review article pertains to the understanding of how combined PPARα and PPARγ activation, which successfully targets the major complications of diabetes, causes cardiac dysfunction. Furthermore, it aims to suggest interventions that will maintain the beneficial effects of dual PPARα/γ agonism and alleviate adverse cardiac outcomes in diabetes.
