Role of apolipoprotein O in autophagy via the p38 mitogen-activated protein kinase signaling pathway in myocardial infarction

Abstract Objectives To explore the role and possible mechanisms of action of apolipoprotein O (APOO) in autophagy in Myocardial Infarction (MI) in vivo and in vitro. Methods Differential gene expression and single Gene Set Enrichment Analysis (GSEA) were used to evaluate MI-related candidate genes. Animal and cell MI models were established. Sh-APOO, si-APOO, and SB203580 were used to inhibit the expression of APOO or p38MAPK. Western blot and qRT-PCR were used to analyze the expression levels of the target protein or mRNA. Apoptosis was observed using the TUNEL assay. The plasma concentrations of CK-MB and cTn-I in humans and mice were determined. Results In the GSE23294 dataset, APOO mRNA was highly expressed in the left ventricle of mice with MI; GSEA revealed that APOO was positively correlated with p38MAPK, autophagy, and apoptosis. The plasma concentration of APOO in patients with MI was significantly higher than that in healthy subjects. The expression of APOO, Beclin-1, LC3, and Bax in mouse and AC16 cell MI models increased, while the level of Bcl-2 decreased. After silencing the APOO gene, the expression of APOO was downregulated; meanwhile, changes in autophagy, apoptosis and myocardial cell injury were reversed in vivo and in vitro. Furthermore, autophagy was alleviated after AC16 cells were treated with SB203580. Conclusions The increased APOO expression in mouse and cell MI models may activate autophagy and apoptosis by regulating the p38MAPK signaling pathway, thus aggravating the myocardial injury. HIGHLIGHTS APOO was highly expressed in the left ventricle of mice with myocardial infarction. Increasing of APOO may activate autophagy and apoptosis in myocardial infarction. The regulation of APOO in autophagy and apoptosis was regulated by p38MAPK signaling pathway.

Effects of Rosuvastatin on Apolipoprotein J in Balloon-Injured Carotid Artery in Rats / Efeitos da Rosuvastatina sobre Apolipoproteína J em Artérias de Ratos Lesionadas com Balão

Abstract Background: Restenosis after percutaneous coronary intervention in coronary heart disease remains an unsolved problem. Clusterin (CLU) (or Apolipoprotein [Apo] J) levels have been reported to be elevated during the progression of postangioplasty restenosis and atherosclerosis. However, its role in neointimal hyperplasia is still controversial. Objective: To elucidate the role Apo J in neointimal hyperplasia in a rat carotid artery model in vivo with or without rosuvastatin administration. Methods: Male Wistar rats were randomly divided into three groups: the control group (n = 20), the model group (n = 20) and the statin intervention group (n = 32). The rats in the intervention group were given 10mg /kg dose of rosuvastatin. A 2F Fogarty catheter was introduced to induce vascular injury. Neointima formation was analyzed 1, 2, 3 and 4 weeks after balloon injury. The level of Apo J was measured by real-time PCR, immunohistochemistry and western blotting. Results: Intimal/medial area ratio (intimal/medial, I/M) was increased after balloon-injury and reached the maximum value at 4weeks in the model group; I/M was slightly increased at 2 weeks and stopped increasing after rosuvastatin administration. The mRNA and protein levels of Apo J in carotid arteries were significantly upregulated after rosuvastatin administration as compared with the model group, and reached maximum values at 2 weeks, which was earlier than in the model group (3 weeks). Conclusion: Apo J served as an acute phase reactant after balloon injury in rat carotid arteries. Rosuvastatin may reduce the neointima formation through up-regulation of Apo J. Our results suggest that Apo J exerts a protective role in the restenosis after balloon-injury in rats.

Resumo Fundamento: A reestenose após intervenção coronária percutânea (ICP) após doença coronariana continua um problema não solucionado. Estudos relataram que os níveis de clusterina (CLU), também chamada de apolipoproteína (Apo) J, encontram-se elevados na progressão da reestenose pós-angioplastia e na aterosclerose. Contudo, seu papel na hihperplasia neointimal ainda é controverso. Objetivo: Elucidar o papel da Apo J na hiperplasia neointimal na artéria carótida utilizando um modelo experimental com ratos in vivo, com e sem intervenção com rosuvastatina. Métodos: ratos Wistar machos foram divididos aleatoriamente em três grupos - grupo controle (n = 20), grupo modelo (n = 20), e grupo intervenção com estatina (n = 32). Os ratos no grupo intervenção receberam 10 mg/kg de rosuvastatina. Um cateter Fogarty 2 F foi introduzido para induzir lesão vascular. A formação de neoíntima foi analisada 1, 2, 3 e 4 semanas após lesão com balão. Concentrações de Apo J foram medidas por PCR em tempo real, imuno-histoquímica e western blotting. Resultados: A razão área íntima/média (I/M) aumentou após a lesão com balão e atingiu o valor máximo 4 semanas pós-lesão no grupo modelo; observou-se um pequeno aumento na I/M na semana 2, que cessou após a administração de rosuvastatina. Os níveis de mRNA e proteína da Apo J nas artérias carótidas aumentaram significativamente após administração de rosuvastatina em comparação ao grupo modelo, atingindo o máximo na semana 2, mais cedo em comparação ao grupo modelo (semana 3). Conclusão: A Apo J atuou como reagente de fase aguda após lesão com balão nas artérias carótidas de ratos. A rosuvastatina pode reduzir a formação de neoíntoma por aumento de Apo J. Nossos resultados sugerem que a Apo J exerce um papel protetor na reestenose após lesão com balão em ratos.
