Possible implication of miR-142-3p in coronary microembolization induced myocardial injury via ATXN1L/HDAC3/NOL3 axis. J Mol Med (Berl) 2022; 100:763-780. [PMID: 35414011 DOI: 10.1007/s00109-022-02198-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 03/30/2022] [Accepted: 04/04/2022] [Indexed: 10/18/2022]
Abstract
This study aims to explore the mechanism underlying miR-142-3p regulating myocardial injury induced by coronary microembolization (CME) through ATXN1L. miR-142-3p overexpression or ATXN1L knockout adenovirus vectors were injected into rats before CME treatment. Cardiac functions were examined by echocardiography, and pathologies of myocardial tissues were assessed. Then, serum cTnI and IL-1β contents and concentrations of IL-1β and IL-18 in cell supernatant were measured. Immunofluorescence determined the localization of histone deacetylase 3 (HDAC3). The interaction between miR-142-3p and ATXN1L as well as the binding between HDAC3 and histone 3 (H3) was identified. The binding of ATXN1L and HDAC3 to NOL3 promoter was verified using ChIP. The levels of ATXN1L, NOL3, and miR-142-3p as well as apoptosis- and pyroptosis-related proteins and acetyl-histone 3 (ac-H3) were evaluated. CME treatment impaired the cardiac functions in rats and increased cTnI content. CME rats showed microinfarction foci in myocardial tissues. After CME treatment, miR-142-3p and NOL3 were modestly expressed while ATXN1L content was elevated, in addition to increases in apoptosis and pyroptosis. miR-142-3p overexpression or ATXN1L knockout alleviated CME-induced myocardial injury, cardiomyocyte apoptosis, and pyroptosis in myocardial tissues. miR-142-3p regulated ATXN1L expression in a targeted manner. In the cellular context, miR-142-3p overexpression attenuated apoptosis and pyroptosis in cardiomyocytes, which was partly counteracted by ATXN1L overexpression. ATXN1L functioned on cardiomyocytes by promoting deacetylation of H3 through HDAC3 and thus inhibited NOL3 expression. Inhibition of HDAC3 or overexpression of NOL3 ameliorated the promotive effects of ATXN1L on cardiomyocyte apoptosis and pyroptosis. In vivo and in vitro evidence in this study supported that miR-142-3p could attenuate CME-induced myocardial injury via ATXN1L/HDAC3/NOL3. HIGHLIGHTS: CME model witnessed aberrant expression of miR-142-3p, ATXN1L, and NOL3; miR-142-3p negatively regulated ATXN1L; miR-142-3p mediated CME-induced myocardial injury through ATXN1L; ATXN1L promoted deacetylation of H3 through HDAC3 and thus inhibited NOL3 expression; ATXN1L acted on cardiomyocyte apoptosis and pyroptosis through HDAC3/NOL3 axis.

Granulocyte colony-stimulating factor attenuates myocardial remodeling and ventricular arrhythmia susceptibility via the JAK2-STAT3 pathway in a rabbit model of coronary microembolization. BMC Cardiovasc Disord 2020; 20:85. [PMID: 32066388 PMCID: PMC7026986 DOI: 10.1186/s12872-020-01385-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 02/10/2020] [Indexed: 02/06/2023] Open
Abstract
Background Coronary microembolization (CME) has a poor prognosis, with ventricular arrhythmia being the most serious consequence. Understanding the underlying mechanisms could improve its management. We investigated the effects of granulocyte colony-stimulating factor (G-CSF) on connexin-43 (Cx43) expression and ventricular arrhythmia susceptibility after CME. Methods Forty male rabbits were randomized into four groups (n = 10 each): Sham, CME, G-CSF, and AG490 (a JAK2 selective inhibitor). Rabbits in the CME, G-CSF, and AG490 groups underwent left anterior descending (LAD) artery catheterization and CME. Animals in the G-CSF and AG490 groups received intraperitoneal injection of G-CSF and G-CSF + AG490, respectively. The ventricular structure was assessed by echocardiography. Ventricular electrical properties were analyzed using cardiac electrophysiology. The myocardial interstitial collagen content and morphologic characteristics were evaluated using Masson and hematoxylin-eosin staining, respectively. Results Western blot and immunohistochemistry were employed to analyze the expressions of Cx43, G-CSF receptor (G-CSFR), JAK2, and STAT3. The ventricular effective refractory period (VERP), VERP dispersion, and inducibility and lethality of ventricular tachycardia/fibrillation were lower in the G-CSF than in the CME group (P < 0.01), indicating less severe myocardial damage and arrhythmias. The G-CSF group showed higher phosphorylated-Cx43 expression (P < 0.01 vs. CME). Those G-CSF-induced changes were reversed by A490, indicating the involvement of JAK2. G-CSFR, phosphorylated-JAK2, and phosphorylated-STAT3 protein levels were higher in the G-CSF group than in the AG490 (P < 0.01) and Sham (P < 0.05) groups. Conclusion G-CSF might attenuate myocardial remodeling via JAK2-STAT3 signaling and thereby reduce ventricular arrhythmia susceptibility after CME.

Abstract
The aim of the present study was to evaluate the feasibility of placing a coronary sinus (CS) catheter through the femoral veins of miniature swine. A total of 16 male domestic pigs (3-4 months old, 25±2 kg) were used. Firstly, the anatomic structure of the CS ostium of swine heart was observed at different angles under X-ray. The guide wire and Cobara catheter were subsequently advanced into the right atrium through the femoral vein. Subsequently, the guide wire was retracted behind the fix curve of the Cobara catheter and the catheter bent spontaneously in the absence of supporting guide wire following retraction. The catheter was then gently rotated clockwise to direct the catheter tip to the left allowing the catheter to easily be placed in the CS ostium. This method was associated with a short procedure time: The time on separation of the blood vessels was 15.5±5.8 min and the time of radiation exposure was 112±20 sec. The success rate of placing the catheter to CS ostium was 100%. Only one pig experienced a hematoma after the sheath was pulled out. All swine recovered without serious complications, such as perforation of coronary vein and pericardial tamponade. Therefore, this method of placing CS catheter is simple, safe and reliable, which may offer help for related research.

Evolution of Coronary Flow in an Experimental Slow Flow Model in Swines: Angiographic and Pathological Insights. BIOMED RESEARCH INTERNATIONAL 2015; 2015:623986. [PMID: 26539516 PMCID: PMC4619871 DOI: 10.1155/2015/623986] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Revised: 08/06/2015] [Accepted: 08/09/2015] [Indexed: 12/22/2022]
Abstract
Objective. Pathomechanism of coronary slow flow phenomenon remains largely unclear now. Present study observed the pathological and angiographic evolution in a pig model of coronary slow flow. Methods. Coronary slow flow was induced by repeat coronary injection of small doses of 40 µm microspheres in 18 male domestic pigs and angiographic and pathological changes were determined at 3 hours, 7 days, and 28 days after microspheres injection. Results. Compared to control group treated with coronary saline injection (n = 6) and baseline level, coronary flow was significantly reduced at 3 hours and 7 days but completely recovered at 28 days after coronary microsphere injection in slow flow group. Despite normal coronary flow at 28 days after microsphere injection, enhanced myocardial cytokine expression, left ventricular dysfunction, adverse remodelling, and ischemia/microembolism related pathological changes still persisted or even progressed from 3 hours to 28 days after coronary microsphere injection. Conclusions. Our results show that this large animal slow flow model could partly reflect the chronic angiographic, hemodynamic, and pathological changes of coronary slow flow and could be used to test new therapy strategies against the slow flow phenomenon.

Abstract
PURPOSE To assess the acute effects of methylprednisone treatment (MPT) on coronary microembolization (CME) by cardiac cine, first-pass perfusion, and delayed gadolinium enhancement magnetic resonance imaging (DE-MRI) in an experimental swine model. MATERIALS AND METHODS Microembolization was established by intracoronary infusion of microspheres into the left anterior artery. Swine received placebo (n = 12) or methylprednisolone (n = 10, 30 mg/kg) intravenously 30 minutes before microembolization. Perfusion and DE-MRI was performed 6 hours after microembolization. Cine MR images of pre-/post-CME were obtained using 1.5T scanner. RESULTS Cine MRI demonstrated relative amelioration of the post-CME myocardial contractile dysfunction in the glucocorticoid-treated group compared to the placebo group (P < 0.001). Post-CME target myocardial perfusion parameters decreased in both groups after microembolization. The extent of these decreases were the same for the embolized-to-control area ratio of maximum upslope (P = 0.245; 95% confidence interval of the difference [CID], -0.041/0.148) and time to peak ratio (P = 0.122; 95% CID, -0.201/0.026); however, the maximum signal intensity was higher in the glucocorticoid-treated group (P = 0.012; 95% CID, 0.023/0.156). DE-MRI revealed patchy hyperenhancement in all placebo pigs (n = 12/12) after microembolization, but no hyperenhanced regions in the glucocorticoid-pretreated pigs (n = 0/10). CONCLUSION Standard, readily available, cardiac MRI techniques are useful in demonstrating post-CME myocardial dysfunction and the acute effects of glucocorticoid treatment on CME. Glucocorticoid pretreatment improves myocardial contractile dysfunction, prevents hyperenhancement, and partially ameliorates the decline of myocardial perfusion in the embolized area.
