Anal Cell Pathol (Amst) 2023; 2023:4500810. [PMID: 38077523 PMCID: PMC10710365 DOI: 10.1155/2023/4500810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 11/03/2023] [Accepted: 11/13/2023] [Indexed: 12/18/2023] Open
Abstract
Background In the present study, we aimed to find out whether luteolin (Lut) pretreatment could ameliorate myocardial ischemia/reperfusion (I/R) injury by regulating the lncRNA just proximal to XIST (JPX)/microRNA-146b (miR-146b) axis. Methods We established the models in vitro (HL-1 cells) and in vivo (C57BL/6J mice) to certify the protection mechanism of Lut pretreatment on myocardial I/R injury. Dual luciferase reporter gene assay was utilized for validating that JPX could bind to miR-146b. JPX and miR-146b expression levels were determined by RT-qPCR. Western blot was utilized to examine apoptosis-related protein expression levels, including cleaved caspase-9, caspase-9, cleaved caspase-3, caspase-3, Bcl-2, Bax, and BAG-1. Apoptosis was analyzed by Annexin V-APC/7-AAD dualstaining, Hoechst 33342 staining, as well as flow cytometry. Animal echocardiography was used to measure cardiac function (ejection fraction (EF) and fractional shortening (FS) indicators). Results miR-146b was demonstrated to bind and recognize the JPX sequence site by dual luciferase reporter gene assay. The expression level of miR-146b was corroborated to be enhanced by H/R using RT-qPCR (P < 0.001 vs. Con). Moreover, JPX could reduce the expression of miR-146b, whereas inhibiting JPX could reverse the alteration (P < 0.001 vs. H/R, respectively). Western blot analysis demonstrated that Lut pretreatment increased BAG-1 expression level and Bcl-2/Bax ratio, but diminished the ratio of cleaved caspase 9/caspase 9 and cleaved caspase 3/caspase 3 (P < 0.001 vs. H/R, respectively). Moreover, the cell apoptosis change trend, measured by Annexin V-APC/7-AAD dualstaining, Hoechst 33342 staining, along with flow cytometry, was consistent with that of apoptosis-related proteins. Furthermore, pretreatment with Lut improved cardiac function (EF and FS) (P < 0.001 vs. I/R, respectively), as indicated in animal echocardiography. Conclusion Our results demonstrated that in vitro and in vivo, Lut pretreatment inhibited apoptosis via the JPX/miR-146b axis, ultimately improving myocardial I/R injury.

Abstract
ABSTRACT Six-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase 2 (PFKFB2) is a key regulator of glycolytic enzyme. This study identified whether PFKFB2 can regulate myocardial ferroptosis in ischemia/reperfusion (I/R) injury. Mice myocardial (I/R) injury and H9c2 cells oxygen-glucose deprivation/reperfusion (OGD/R) models were established. PFKFB2 expression was enhanced in I/R mice and OGD/R H9c2 cells. Overexpression of PFKFB2 improves heart function in I/R mice. Overexpression of PFKFB2 inhibits I/R and OGD/R-induced ferroptosis in mice and H9c2 cells. Mechanistically, overexpression of PFKFB2 activates the adenosine monophosphate-activated protein kinase (AMPK). AMPK inhibitor compound C reverses effect of PFKFB2 overexpression in reducing ferroptosis under OGD/R treatment. In conclusion, PFKFB2 protects hearts against I/R-induced ferroptosis through activation of the AMPK signaling pathway.

Abstract
Background Cardiovascular tissue engineering (CTE) is a promising technique to treat incurable cardiovascular diseases, such as myocardial infarction and ischemic cardiomyopathy. Plenty of studies related to CTE have been published in the last 30 years. However, an analysis of the research status, trends, and potential directions in this field is still lacking. The present study applies a bibliometric analysis to reveal CTE research trends and potential directions. Methods On 5 August 2022, research articles and review papers on CTE were searched from the Web of Science Core Collection with inclusion and exclusion criteria. Publication trends, research directions, and visual maps in this field were obtained using Excel (Microsoft 2009), VOSviewer, and Citespace software. Results A total of 2,273 documents from 1992 to 2022 were included in the final analysis. Publications on CTE showed an upward trend from 1992 [number of publications (Np):1] to 2021 (Np:165). The United States (Np: 916, number of citations: 152,377, H-index: 124) contributed the most publications and citations in this field. Research on CTE has a wide distribution of disciplines, led by engineering (Np: 788, number of citations: 40,563, H-index: 105). "Functional maturation" [red cluster, average published year (APY): 2018.63, 30 times], "cell-derived cardiomyocytes" (red cluster, APY: 2018.43, 46 times), "composite scaffolds" (green cluster, APY: 2018.54, 41 times), and "maturation" (red cluster, APY: 2018.17, 84 times) are the main emerging keywords in this area. Conclusion Research on CTE is a hot research topic. The United States is a dominant player in CTE research. Interdisciplinary collaboration has played a critical role in the progress of CTE. Studies on functional maturation and the development of novel biologically relevant materials and related applications will be the potential research directions in this field.

Abstract
BACKGROUND Acute myocardial infarction is a major health problem and is the leading cause of death worldwide. Myocardial apoptosis induced by myocardial infarction injury is involved in the pathophysiology of heart failure. Therapeutic stem cell therapy has the potential to be an effective and favorable treatment for ischemic heart disease. Exosomes derived from stem cells have been shown to effectively repair MI injury-induced cardiomyocyte damage. However, the cardioprotective benefits of adipose tissue-derived mesenchymal stem cell (ADSC)-Exos remain unknown. This study aimed to investigate the protective effects of exosomes from ADSC on the hearts of MI-treated mice and to explore the underlying mechanisms. METHODS Cellular and molecular mechanisms were investigated using cultured ADSCs. On C57BL/6J mice, we performed myocardial MI or sham operations and assessed cardiac function, fibrosis, and angiogenesis 4 weeks later. Mice were intramyocardially injected with ADSC-Exos or vehicle-treated ADSCs after 25 min following the MI operation. RESULTS Echocardiographic experiments showed that ADSC-Exos could significantly improve left ventricular ejection fraction, whereas ADSC-Exos administration could significantly alleviate MI-induced cardiac fibrosis. Additionally, ADSC-Exos treatment has been shown to reduce cardiomyocyte apoptosis while increasing angiogenesis. Molecular experiments found that exosomes extracted from ADSCs can promote the proliferation and migration of microvascular endothelial cells, facilitate angiogenesis, and inhibit cardiomyocytes apoptosis through miRNA-205. We then transferred isolated exosomes from ADSCs into MI-induced mice and observed decreased cardiac fibrosis, increased angiogenesis, and improved cardiac function. We also observed increased apoptosis and decreased expression of hypoxia-inducible factor-1α and vascular endothelial growth factor in HMEC-1 transfected with a miRNA-205 inhibitor. CONCLUSION In summary, these findings show that ADSC-Exos can alleviate cardiac injury and promote cardiac function recovery in MI-treated mice via the miRNA-205 signaling pathway. ADSC-Exos containing miRNA205 have a promising therapeutic potential in MI-induced cardiac injury.

Abstract
The imbalance of mitochondrial fission and fusion dynamics causes ischemic cardiomyocyte apoptosis and heart injury by affecting mitophagy. Regulation of mitochondrial dynamics is an important therapeutic strategy for ischemic heart diseases. Considering the important roles of MORN motifs in heart diseases and chloroplast fission, we aimed to investigate the possible role of MORN repeat-containing protein 4 (MORN4) in the progression of myocardial infarction (MI), ischemic cardiomyocyte apoptosis, mitochondrial dynamics, and mitophagy. We found that in the MI mouse, MORN4 knockdown remarkably accelerated cardiac injury and fibrosis with deteriorating cardiac dysfunction. Sphingosylphosphorylcholine (SPC) alleviated ischemic cardiomyocyte apoptosis and heart injury through increased level of MORN4, indicating a vital function of MORN4 in heart with SPC used to clarify the molecular mechanisms underlying the functions of MORN4. Mechanistically, we found that MORN4 directly binds to MFN2 and promotes the phosphorylation of MFN2 S442 through Rho-associated protein kinase 2 (ROCK2), which mediates beneficial mitophagy induced by mitochondrial dynamics, while SPC promoted the binding of MORN4 and MFN2 and the process. Taken together, our data reveal a new perspective role of MORN4 in ischemic heart injury, and report that SPC could regulate myocardial mitochondrial homeostasis by activating the MORN4-MFN2 axis during the ischemic situation, this finding provides novel targets for improving myocardial ischemia tolerance and rescue of acute myocardial infarction.

Abstract
Adipose-derived stem cells (ADSCs) are a type of adult mesenchymal stem cell that show a repair effect on ischemic tissues owing to their capacity for endothelial differentiation. MicroRNA-221/222 (miR-221/222) has been extensively studied in endothelial cells (ECs). However, the mechanism that regulates ADSCs differentiation into ECs remains unknown. In this study, we investigated the effects of miR-221/222-overexpression/silence in ADSCs on endothelial differentiation by constructing lentiviral vectors. Differentiation capacity was assessed by measuring the expression of endothelial markers (CD31, CD34, and CD144). In addition, low-density lipoprotein (LDL) uptake and tube-like formation were performed for evaluation of functional characterization. The PTEN/PI3K/AKT/mTOR signaling pathway was investigated using western blotting to clarify the action mechanism of this gene. The revascularization of miR-221/222-transfeted ADSCs was further verified in a rat hind limb ischemia model. The results confirmed that transfection with miR-221/222 promoted the expression of endothelial markers, LDL uptake, and tube-like formation. As expected, the PI3K/AKT signaling pathway was effectively activated when ADSCs showed high expression of miR-221/222 during endothelial differentiation. Furthermore, injection of miR-221/222 transfected ADSCs significantly improved rat hindlimb ischemia, as evidenced by increased blood flow and structural integrity and reduce inflammatory infiltration. The results of this study suggest that miR-221/222 is essential for endothelial differentiation of ADSCs and provides a novel strategy for modulating vascular formation and ischemic tissue regeneration.

Abstract
Asiaticoside is a natural triterpene compound derived from Centella asiatica, possessing confirmed cardioprotective property. However, the roles of asiaticoside in regulating oxygen-glucose deprivation/reoxygenation (OGD/R)-caused cardiomyocyte dysfunction remain largely obscure. Human cardiomyocyte AC16 cells were stimulated with OGD/R to mimic myocardial ischemia/reperfusion injury and treated with asiaticoside. Cytotoxicity was investigated by CCK-8 assay and lactate dehydrogenase (LDH) release analysis. Autophagy- and Wnt/β-catenin signaling-related protein levels were measured via western blotting. Asiaticoside (0-20 μM) did not induce cardiomyocyte cytotoxicity. Asiaticoside (20 μM) mitigated OGD/R-induced autophagy, cytotoxicity, oxidative stress, and myocardial injury. Rapamycin, an autophagy inductor, reversed the influences of asiaticoside on autophagy, cytotoxicity, oxidative stress, and myocardial injury, whereas 3-methyadanine, an autophagy inhibitor, played an opposite effect. Asiaticoside (20 μM) attenuated OGD/R-induced Wnt/β-catenin signaling inactivation, which was reversed after transfection with si-β-catenin. Transfection with si-β-catenin attenuated the influences of asiaticoside on autophagy, cytotoxicity, oxidative stress, and myocardial injury. In conclusion, asiaticoside protected against OGD/R-induced cardiomyocyte cytotoxicity, oxidative stress, and myocardial injury via blunting autophagy through activating the Wnt/β-catenin signaling, indicating the therapeutic potential of asiaticoside in myocardial ischemia/reperfusion injury.

ALOX15-launched PUFA-phospholipids peroxidation increases the susceptibility of ferroptosis in ischemia-induced myocardial damage. Signal Transduct Target Ther 2022; 7:288.

Abstract
Myocardial ischemia/reperfusion (I/R) injury is a classic type of cardiovascular disease characterized by injury to cardiomyocytes leading to various forms of cell death. It is believed that irreversible myocardial damage resulted from I/R occurs due to oxidative stress evoked during the reperfusion phase. Here we demonstrate that ischemia triggers a specific redox reaction of polyunsaturated fatty acids (PUFA)-phospholipids in myocardial cells, which acts as a priming signaling that initiates the outbreak of robust oxidative damage in the reperfusion phase. Using animal and in vitro models, the crucial lipid species in I/R injury were identified to be oxidized PUFAs enriched phosphatidylethanolamines. Using multi-omics, arachidonic acid 15-lipoxygenase-1 (ALOX15) was identified as the primary mediator of ischemia-provoked phospholipid peroxidation, which was further confirmed using chemogenetic approaches. Collectively, our results reveal that ALOX15 induction in the ischemia phase acts as a “burning point” to ignite phospholipid oxidization into ferroptotic signals. This finding characterizes a novel molecular mechanism for myocardial ischemia injury and offers a potential therapeutic target for early intervention of I/R injury.

Wu Q, Liu F, Shen T, Zhang W. Multiple pathways are responsible to the inhibitory effect of butorphanol on OGD/R-induced apoptosis in AC16 cardiomyocytes. J Appl Toxicol 2021; 42:830-840. [PMID: 34708435 DOI: 10.1002/jat.4260] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 09/28/2021] [Accepted: 10/11/2021] [Indexed: 12/15/2022]
Abstract
Ischemic heart disease is the leading cause of cardiovascular mortality, which is related to cardiac myocyte apoptosis. Butorphanol is an opioid receptor agonist with potential cardioprotective function. The purpose of this work is to explore the function and mechanism of butorphanol in oxygen and glucose deprivation/reperfusion (OGD/R)-induced cardiomyocyte apoptosis. The overlapping targets of ischemic heart disease and butorphanol were analyzed according to GeneCards, ParmMapper, Cytoscape, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Human cardiomyocyte AC16 cells were incubated with butorphanol and then stimulated with OGD/R. Cell injury was investigated by Cell Counting Kit-8, lactate dehydrogenase (LDH) assay kit, TUNEL staining, caspase-3 activity assay kit, and Western blotting. The proteins in signaling pathways were measured using Western blotting. A total of 93 overlapping targets of ischemic heart disease and butorphanol were obtained. Pathway analysis exhibited that these targets might be involved in multiple signaling pathways. Butorphanol alone showed little cytotoxicity to cardiomyocytes, and it protected against OGD/R-induced viability inhibition, LDH release, cell apoptosis, and increase of caspase-3 activity and expression levels of cleaved caspase-3 and Bim. Butorphanol promoted the activation of the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/forkhead box O (FoxO) and hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) pathways and attenuated the activation of the mitogen-activated protein kinase (MAPK) signaling in OGD/R-treated cardiomyocytes. In conclusion, butorphanol prevents OGD/R-induced cardiomyocyte apoptosis through activating the PI3K/Akt/FoxO and HIF-1α/VEGF pathways and inactivating the MAPK pathway.
