目的
2
探讨circTRRAP在急性心肌梗死(acute myocardial infarction,AMI)中的特定作用。
方法
2
心肌梗死模型由缺氧24 h诱导。使用双萤光素酶报告基因测定来测试circTRRAP、SMAD2和miR-323-3p之间的相互作用。通过转染si-circTRRAP,敲低与过表达microRNA-323-3p、过表达SMAD2后检测促炎细胞因子[白细胞介素-6(interkeukin-6,IL-6)与肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)]和氧化应激标志物[丙二醛(malondialdehyde,MDA)与超氧化物歧化酶(superoxide dismutase,SOD)]以及细胞凋亡因子[Bcl-2相关X蛋白(Bcl-2-associated X protein,Bax)、B细胞淋巴瘤-2(B-cell lymphoma-2,Bcl-2),Cleaved Caspase-3]表达来研究其在心肌梗死细胞中作用。
结果
2
在心肌梗死损伤模型中,circTRRAP与SMAD2水平明显升高超过50%,而miR-323-3p表达明显降低。circTRRAP的下调通过促进miR-323-3p表达导致SMAD2的表达减少。SMAD2与miR-323-3p呈负相关,但与circTRRAP表达呈正相关。circTRRAP与SMAD2的下调或miR-323-3p的上调可提高细胞活力与减少心肌细胞凋亡率。
结论
2
circTRRAP 的下调导致炎症的抑制,并通过miR-323-3p/SMAD2 轴减轻AMI。
Objective
2
To investigate the specific role of circTRRAP in acute myocardial infarction(AMI).
Methods
2
The method of hypoxia for 24 hours was used to induce the model of myocardial infarction,and the dual-luciferase reporter assay was used to investigate the interaction between circTRRAP,SMAD2,and miR-323-3p. After knockdown and overexpression of miR-323-3p and overexpression of SMAD2 through transfection with si-circTRRAP,the expression levels of proinflammatory cytokines [interkeukin-6(IL-6) and tumor necrosis factor-α(TNF-α)],oxidative stress markers [malondialdehyde(MDA) and superoxide dismutase(SOD)],and apoptotic factors[Bcl-2-associated X protein(Bax),B-cell lymphoma-2(Bcl-2),and cleaved caspase-3]were measured to investigate the role of circTRRAP,SMAD2,and miR-323-3p in myocardial infarction.
Results
2
In the model of myocardial infarction injury,the levels of circTRRAP and SMAD2 were significantly increased by more than 50%,whereas there was a significant reduction in the expression of miR-323-3p. The downregulation of circTRRAP led to a reduction in SMAD2 expression by promoting miR-323-3p expression. SMAD2 was negatively correlated with miR-323-3p,but it was positively correlated with the expression of circTRRAP. The downregulation of circTRRAP or SMAD2 or the upregulation of miR-323-3p could increase cell viability and reduce the apoptosis rate of cardiomyocytes.
Conclusion
2
Downregulation of circTRRAP can inhibit inflammation and alleviate AMI via the miR-323-3p/SMAD2 axis.
