Abstract
Dendrobium officinale polysaccharide (DP) was prepared with lactic acid bacterium fermentation to overcome the large molecular weight and complex structure of traditional DP for improving its functional activity and application range in this work. The structure was analyzed, and then the functional activity was evaluated using a mouse model of alcoholic liver damage. The monosaccharide compositions were composed of four monosaccharides: arabinose (0.13%), galactose (0.50%), glucose (24.38%), and mannose (74.98%) with a molecular weight of 2.13 kDa. The connection types of glycosidic bonds in fermented D. officinale (KFDP) were →4)-β-D-Manp(1→, →4)-β-Glcp(1→, β-D-Manp(1→, and β-D-Glcp(1→. KFDP exhibited an excellent protective effect on alcoholic-induced liver damage at a dose of 80 mg/kg compared with polysaccharide separated and purified from D. officinale without fermentation (KDP), which increased the activity of GSH, GSH-Px, and GR and decreased the content of MDA, AST, T-AOC, and ALT, as well as regulated the level of IL-6, TNF-α, and IL-1β to maintain the normal functional structure of hepatocytes and retard the apoptosis rate of hepatocytes. The results proved that fermentation degradation is beneficial to improving the biological activity of polysaccharides. The potential mechanism of KFDP in protecting alcoholic liver damage was inhibiting the expression of miRNA-150-5p and targeting to promote the expression of Pik3r1. This study provides an important basis for the development of functional foods.

Neuronal Stem Cells from Late-Onset Alzheimer Patients Show Altered Regulation of Sirtuin 1 Depending on Apolipoprotein E Indicating Disturbed Stem Cell Plasticity. Mol Neurobiol 2024; 61:1562-1579.

Abstract
Late-onset Alzheimer's disease (AD) is a complex multifactorial disease. The greatest known risk factor for late-onset AD is the E4 allele of the apolipoprotein E (APOE), while increasing age is the greatest known non-genetic risk factor. The cell type-specific functions of neural stem cells (NSCs), in particular their stem cell plasticity, remain poorly explored in the context of AD pathology. Here, we describe a new model that employs late-onset AD patient-derived induced pluripotent stem cells (iPSCs) to generate NSCs and to examine the role played by APOE4 in the expression of aging markers such as sirtuin 1 (SIRT1) in comparison to healthy subjects carrying APOE3. The effect of aging was investigated by using iPSC-derived NSCs from old age subjects as healthy matched controls. Transcript and protein analysis revealed that genes were expressed differently in NSCs from late-onset AD patients, e.g., exhibiting reduced autophagy-related protein 7 (ATG7), phosphatase and tensin homolog (PTEN), and fibroblast growth factor 2 (FGF2). Since SIRT1 expression differed between APOE3 and APOE4 NSCs, the suppression of APOE function in NSCs also repressed the expression of SIRT1. However, the forced expression of APOE3 by plasmids did not recover differently expressed genes. The altered aging markers indicate decreased plasticity of NSCs. Our study provides a suitable in vitro model to investigate changes in human NSCs associated with aging, APOE4, and late-onset AD.

CNS Neurosci Ther 2023; 29:3598-3611. [PMID: 37308778 PMCID: PMC10580367 DOI: 10.1111/cns.14291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 04/06/2023] [Accepted: 05/24/2023] [Indexed: 06/14/2023] Open
Abstract
BACKGROUND Neuronal abnormalities are closely associated with major depressive disorder (MDD). Available evidence suggests a role for microRNAs (miRNAs) in regulating the expression of genes involved in MDD. Hence, miRNAs that can be potential therapeutic targets need to be identified. METHODS A mouse model of chronic unpredictable stress (CUS) was used to evaluate the function of miRNAs in MDD. miR-144-5p was screened from the hippocampi of CUS mice based on sequencing results. Adenovirus-associated vectors were used to overexpress or knockdown miR-144-5p in mice. BpV(pic) and LY294002 were used to determine the relationship between miR-144-5p target genes PTEN and TLR4 in neuronal impairment caused by miR-144-5p deficiency. Western blotting, immunofluorescence, ELISA immunosorbent assay, and Golgi staining were used to detect neuronal abnormalities. Serum samples from healthy individuals and patients with MDD were used to detect miR-144-5p levels in the serum and serum exosomes using qRT-PCR. RESULTS miR-144-5p expression was significantly decreased within the hippocampal dentate gyrus (DG) of CUS mice. Upregulation of miR-144-5p in the DG ameliorated depression-like behavior in CUS mice and attenuated neuronal abnormalities by directly targeting PTEN and TLR4 expression. Furthermore, miR-144-5p knockdown in normal mice led to depression-like behavior via inducing neuronal abnormalities, including abnormal neurogenesis, neuronal apoptosis, altered synaptic plasticity, and neuroinflammation. miR-144-5p deficiency-mediated neuronal impairment was mediated by PI3K/Akt/FoxO1 signaling. Furthermore, miR-144-5p levels were downregulated in the sera of patients with MDD and associated with depressive symptoms. Consistently, serum exosome-derived miR-144-5p levels were decreased in patients with MDD. CONCLUSION miR-144-5p plays a vital role in regulating neuronal abnormalities in depression. Our findings provide translational evidence that miR-144-5p is a new potential therapeutic target for MDD.

Abstract
Due to the limited capacity of the adult mammalian brain to self-repair and regenerate, neurological diseases, especially neurodegenerative disorders and stroke, characterized by irreversible cellular damage are often considered as refractory diseases. Neural stem cells (NSCs) play a unique role in the treatment of neurological diseases for their abilities to self-renew and form different neural lineage cells, such as neurons and glial cells. With the increasing understanding of neurodevelopment and advances in stem cell technology, NSCs can be obtained from different sources and directed to differentiate into a specific neural lineage cell phenotype purposefully, making it possible to replace specific cells lost in some neurological diseases, which provides new approaches to treat neurodegenerative diseases as well as stroke. In this review, we outline the advances in generating several neuronal lineage subtypes from different sources of NSCs. We further summarize the therapeutic effects and possible therapeutic mechanisms of these fated specific NSCs in neurological disease models, with special emphasis on Parkinson's disease and ischemic stroke. Finally, from the perspective of clinical translation, we compare the strengths and weaknesses of different sources of NSCs and different methods of directed differentiation, and propose future research directions for directed differentiation of NSCs in regenerative medicine.

Potential Regulation of miRNA-29 and miRNA-9 by Estrogens in Neurodegenerative Disorders: An Insightful Perspective. Brain Sci 2023; 13:brainsci13020243.

Abstract
Finding a link between a hormone and microRNAs (miRNAs) is of great importance since it enables the adjustment of genetic composition or cellular functions without needing gene-level interventions. The dicer-mediated cleavage of precursor miRNAs is an interface link between miRNA and its regulators; any disruption in this process can affect neurogenesis. Besides, the hormonal regulation of miRNAs can occur at the molecular and cellular levels, both directly, through binding to the promoter elements of miRNAs, and indirectly, via regulation of the signaling effects of the post-transcriptional processing proteins. Estrogenic hormones have many roles in regulating miRNAs in the brain. This review discusses miRNAs, their detailed biogenesis, activities, and both the general and estrogen-dependent regulations. Additionally, we highlight the relationship between miR-29, miR-9, and estrogens in the nervous system. Such a relationship could be a possible etiological route for developing various neurodegenerative disorders.

Abstract
Background Exosomes derived from the bone marrow mesenchymal stem cell (MSC) have shown great potential in spinal cord injury (SCI) treatment. This research was designed to investigate the therapeutic effects of miR-26a-modified MSC-derived exosomes (Exos-26a) following SCI. Methods Bioinformatics and data mining were performed to explore the role of miR-26a in SCI. Exosomes were isolated from miR-26a-modified MSC culture medium by ultracentrifugation. A series of experiments, including assessment of Basso, Beattie and Bresnahan scale, histological evaluation, motor-evoked potential recording, diffusion tensor imaging, and western blotting, were performed to determine the therapeutic influence and the underlying molecular mechanisms of Exos-26a in SCI rats. Results Exos-26a was shown to promote axonal regeneration. Furthermore, we found that exosomes derived from miR-26a-modified MSC could improve neurogenesis and attenuate glial scarring through PTEN/AKT/mTOR signaling cascades. Conclusions Exosomes derived from miR-26a-modified MSC could activate the PTEN-AKT-mTOR pathway to promote axonal regeneration and neurogenesis and attenuate glia scarring in SCI and thus present great potential for SCI treatment.

Abstract
Rapid and extensive bone loss, one of the skeletal complications after spinal cord injury (SCI) occurrence, drastically sacrifices the life quality of SCI patients. It has been demonstrated that microRNA (miRNA) dysfunction plays an important role in the initiation and development of bone loss post-SCI. Nevertheless, the effect of miR-19b-3p on bone loss after SCI is unknown and the accurate mechanism is left to be elucidated. The present work was conducted to explore the role of miR-19b-3p/phosphatase and tensin homolog deleted on chromosome ten (PTEN) axis on osteogenesis after SCI and further investigates the underlying mechanisms. We found that miR-19b-3p level was increased in the femurs of SCI rats with decreased autophagy. The overexpression of miR-19b-3p in bone marrow mesenchymal stem cells (BMSCs) targeted down-regulation of PTEN expression, facilitated protein kinase B (Akt) and mammalian target of rapamycin (mTOR) phosphorylation, and thereby suppressing BMSCs osteogenic differentiation via autophagy. Besides, the inhibiting effects of miR-19b-3p on osteogenic differentiation of BMSCs could be diminished by autophagy inducer rapamycin. Meanwhile, bone loss after SCI in rats was also reversed by antagomir-19b-3p treatment, suggesting miR-19b-3p was an essential target for osteogenic differentiation via regulating autophagy. These results indicated that miR-19b-3p was involved in bone loss after SCI by inhibiting osteogenesis via PTEN/Akt/mTOR signalling pathway.

Abstract
Isoflurane (ISO) is an anesthesia and can result in neuron injury. A previous study has indicated that microRNA-302b-3p (miR-302b-3p) exerts a crucial function in modulating cerebral ischemia/reperfusion damage-induced neuronal injury. We sought to examine the role of miR-302b-3p in ISO-induced neuronal injury. In the present study, the effects of miR-302b-3p on ISO-induced neuron injury were investigated by MTT and TUNEL assays. We discovered that ISO stimulation led to miR-302b-3p upregulation and neuronal injury. MiR-302b-3p silencing exerted protective effects against ISO induced neuronal injury. In addition, phosphatase and tensin homologue deleted on chromosome 10 (PTEN) was a direct downstream target gene of miR-302b-3p. MiR-302b-3p targets the 3'UTR of PTEN to inhibit its mRNA expression, and further reduces its protein expression. Silencing of PTEN partially reversed the protecting effects of silenced miR-302b-3p on ISO-induced injury of hippocampal neurons. Further, miR-302b-3p activated the AKT signaling pathway in neurons exposed to ISO by downregulation of PTEN. Finally, in vivo studies revealed that silencing of miR-302b-3p alleviates ISO-induced injury and spatial memory impairment of rats partly by upregulation of PTEN. Overall, our findings indicated that miR-302b-3p targets PTEN to activate the AKT pathway, and silencing of miR-302b-3p plays a neuroprotective role in ISO-induced neuronal injury by the PTEN/AKT pathway, suggesting miR-302b-3p as a crucial target for ISO-induced neuronal injury.

[PMID: 32993796 PMCID: PMC7523391 DOI: 10.1186/s13287-020-01936-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 08/28/2020] [Accepted: 09/15/2020] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Currently, numerous animal studies have shown that exposure to commonly used general anesthetics during pregnancy may cause neurocognitive impairment in the offspring. Reportedly, exposure to sevoflurane during mid-trimester of pregnancy can inhibit proliferation of neural stem cells (NSCs) and lead to early apoptosis. Whether exposure to sevoflurane during pregnancy affects the differentiation of NSCs remains unclear. METHODS In the present study, pregnant rats were exposed to 3% sevoflurane once for 2 h on gestational day 14 (G14) or 3 times for 2 h on G13, G14, and G15. Next, the differentiation of NSCs was measured using neuron marker β-tubulin III and astrocyte marker glial fibrillary acidic protein (GFAP) in fetal brain tissues 24 h and 72 h after anesthesia and in hippocampus on postnatal day 28. Primary cultured rat NSCs were exposed to 4.1% sevoflurane to explore the mechanism. RESULTS The results showed that during mid-trimester, multiple exposures to sevoflurane can cause premature differentiation of NSCs in developing brains of offspring and lead to long-term neuron reduction and astrocyte proliferation in hippocampus. The data from the present study indicated that repeated exposure to sevoflurane downregulated atrophin-1 (ATN1) expression and caused early differentiation of NSCs. Overexpression of ATN1 via lentivirus transfection attenuated the influence of sevoflurane. Using dual luciferase assay, ATN1 was found to be a target gene of microRNA-410-3p (miR-410-3p). MiR-410-3p suppression via lentivirus transfection recovered the ATN1 expression and differentiation of NSCs. CONCLUSIONS The results from the present study demonstrated that repeated exposure to sevoflurane leads to early differentiation of NSCs and long-term effects via the miR-410-3p/ATN1 pathway.

Abstract
Background Spinal cord injury (SCI) is a debilitating neuropathological condition that significantly affects the quality of life. The present study is basic research examining the underlying mechanisms of NEAT1 and miR-29a in regulating LPS-induced PC-12 cell injury. Material/Methods The model of cell injury was induced by the treatment of PC-12 cells with LPS. The expressions of NEAT1, miR-29a, and inflammatory cytokines were measured by real-time quantitative polymerase chain reactions (RT-qPCR). Cell proliferation and apoptosis were evaluated by CCK-8 and flow cytometry, respectively. Finally, the target between miR-29a and NEAT1 as well as miR-29a and BCL2L11 was investigated by luciferase and RNA pull-down assays. Results Knockdown of NEAT1 can inhibit inflammatory cytokine expression and PC-12 cell apoptosis and promote PC-12 cell proliferation by targeting miR-29a. However, the variation caused by NEAT1 knockdown can be reversed by the silencing of miR-29a and the overexpression of BCL2L11, which is the direct target gene of miR-29a. Conclusions High NEAT1 levels can increase LPS-induced injury in PC-12 cells through the miR-29a/BCL2L11 pathway. lncRNA NEAT1 may, therefore, be a promising target for SCI treatment.

Abstract
Neural stem cells (NSCs) can generate new neurons to repair brain injury and central nervous system disease by promoting neural regeneration. MicroRNAs (miRNAs) involve in neural development, brain damage, and neurological diseases repair. Recent reports show that several miRNAs express in NSCs and are important to neurogenesis. Neurites play a key role in NSC-related neurogenesis. However, the mechanism of NSC neurite generation is rarely studied. We surprisingly noticed that the neurites increased after bone morphogenetic protein (BMP) treatment in rat NSCs. This process was accompanied by the dynamic change of miRNA-29. Then we discovered that miR-29a regulated neural neurites in rat hippocampus NSCs. Overexpression of miR-29a reduced the cell soma area and promoted the neurite outgrowth of NSCs. Cell soma area became small, whereas the number of neurite increased. Moreover, neurite complexity increased dramatically, with more primary and secondary branches after miR-29a overexpression. In addition, miR-29a overexpression still maintained the stemness of NSCs. Besides, we identified that miR-29a can promote the neurite outgrowth by targeting extracellular matrix-related genes like Fibrillin 1 (Fbn1), Follistatin-like 1 (Fstl1), and laminin subunit gamma 2 (Lamc2). These findings may provide a novel role of miR-29a to regulate neurite outgrowth and development of NSCs. We also offered a possible theoretical basis to the migration mechanism of NSCs in brain development and damage repair.

Abstract
Retinoic acid can cause many types of cells, including mouse neuroblastoma Neuro-2A cells, to differentiate into neurons. However, it is still unknown whether microRNAs (miRNAs) play a role in this neuronal differentiation. To address this issue, real-time polymerase chain reaction assays were used to detect the expression of several differentiation-related miRNAs during the differentiation of retinoic acid-treated Neuro-2A cells. The results revealed that miR-124 and miR-9 were upregulated, while miR-125b was downregulated in retinoic acid-treated Neuro-2A cells. To identify the miRNA that may play a key role, miR-124 expression was regulated by transfection of miRNA mimics or inhibitors. Morphological analysis results showed that inhibition of miR-124 expression reversed the effects of retinoic acid on neurite outgrowth. Moreover, miR-124 overexpression alone caused Neuro-2A cells to differentiate into neurons, and its inhibitor could block this effect. These results suggest that miR-124 plays an important role in retinoic acid-induced differentiation of Neuro-2A cells.

Abstract
Prostate cancer (PCa) is considered as a common visceral cancer in males and the sixth major cause of cancer-related deaths in males worldwide. Significant diagnostic and therapeutic advances have been made in the past decades. However, an improved understanding of their molecular mechanism is still needed. In the present research, we first detected the expression of miR-146b by quantitative real-time PCR (qRT-PCR) and found that miR-146b expression was increased in PCa. Subsequently, we found that miR-146b play an important role in the viability and proliferation capacity of PCa cells functionally. To explore the mechanism, we performed western blot to examine the autophagy-related markers, and found that miR‑146b may promote autophagy in PCa cells via activation of PTEN/AKT/mTOR signaling pathway. Furthermore, we performed the dual luciferase reporter assay to clarify the relationship between miR-146b and PTEN. In conclusion, this study demonstrated that miR-146b inhibited autophagy in PCa by targeting the PTEN/Akt/mTOR signaling pathway, and it could be a potential candidate for application in the treatment of PCa.

Abstract
AIM Although miR-29 has emerged as a crucial non-coding RNA in the regulation of pathological cardiac hypertrophy, further exploration of its specific mechanisms is necessary to resolve controversy about its major role in this condition. This study therefore evaluated the role of miR-29a and whether it acts through the PTEN/AKT/mTOR pathway. METHODS In this study, a rat model of pressure-induced cardiac hypertrophy was established by transverse aortic constriction and verified by echocardiography, histological analysis and quantitative RT-PCR. At the cellular level, we explored the role of miR-29a in angiotensin II-stimulated hypertrophic H9c2 cardiomyoblasts by transfecting the cells with miR-29a inhibitor and mimic. The relationship between miR-29a and the signalling pathway was investigated with dual luciferase reporter assays, immunofluorescence analysis and Western blotting. We also examined whether autophagy is involved in the regulatory mechanism of miR-29a through transmission electron microscopy and detection of autophagy-associated proteins. RESULTS The results showed that miR-29a was upregulated both in rats 4 weeks after surgery and in 10-6 M angiotensin II-stimulated cells. In contrast, inhibition of miR-29a partially attenuated angiotensin II-induced hypertrophy. Additionally, bioinformatics analysis revealed that PTEN was one of the target genes of miR-29a, which was also verified by luciferase assay. The results of immunofluorescence and Western blotting indicated that overexpression of miR-29a inhibited the expression of PTEN, activated the AKT/mTOR pathway and suppressed autophagy, which ultimately led to cardiac hypertrophy. CONCLUSION In pathological cardiac hypertrophy, miR-29a was overexpressed and promoted cardiac hypertrophy by regulating the PTEN/AKT/mTOR pathway and suppressing autophagy.

Abstract
Hepatocellular carcinoma (HCC) is known as a frequent type of primary cancer in the liver, and it is the third-most common cause of cancer-related death all over the world. However, the molecular mechanism in the progression of HCC is still unclear. The current study was designed to investigate the expression and function of microRNA-34a (miR-34a) in HCC. In HCC tissues and cells, the expression levels of miR-34a were analyzed by quantitative real-time polymerase chain reaction. The association between the level of miR-34a and hexokinase (HK)-1 was also investigated via luciferase reporter assay. Cell viability and proliferation were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and flow cytometry. To assess whether miR-34a can limit tumor growth in vivo, animal models and terminal deoxynucleotidyl transferase dUTP nick end labeling assay were used for examining the role of miR-34a on the development of HCC and cell apoptosis. The expression level of miR-34a was reduced in HCC samples and cells. The expression of miR-34a was associated with the viability and proliferation capacity of HCC cells, and miR-34a could inhibit HCC cells proliferation by inhibiting HK1. In the mouse model of HCC, volumes and weight of the tumors were significantly decreased by transfection with miR-34a mimic compared with the control group. Furthermore, miR-34a mimics could induce apoptosis in a greater proportion of cells compared with the control group. Taken together, the data may provide some novel insights into the molecular mechanism of miR-34a and HK1 in the progression of HCC. Thus, miR-34a/HK1 axis might be a novel promising therapeutic target for treating HCC.

Abstract
Background Glioblastoma is a malignant brain tumor characterized by rapid growth, diffuse invasion and therapeutic resistance. We recently used microRNA expression profiles to subclassify glioblastoma into five genetically and clinically distinct subclasses, and showed that microRNAs both define and contribute to the phenotypes of these subclasses. Here we show that miR-29a activates a multi-faceted growth and invasion program that promotes glioblastoma aggressiveness. Methods microRNA expression profiles from 197 glioblastomas were analyzed to identify the candidate miRNAs that are correlated to glioblastoma aggressiveness. The candidate miRNA, miR-29a, was further studied in vitro and in vivo. Results Members of the miR-29 subfamily display increased expression in the two glioblastoma subclasses with the worst prognoses (astrocytic and neural). We observed that miR-29a is among the microRNAs that are most positively-correlated with PTEN copy number in glioblastoma, and that miR-29a promotes glioblastoma growth and invasion in part by targeting PTEN. In PTEN-deficient glioblastoma cells, however, miR-29a nevertheless activates AKT by downregulating the metastasis suppressor, EphB3. In addition, miR-29a robustly promotes invasion in PTEN-deficient glioblastoma cells by repressing translation of the Sox4 transcription factor, and this upregulates the invasion-promoting protein, HIC5. Indeed, we identified Sox4 as the most anti-correlated predicted target of miR-29a in glioblastoma. Importantly, inhibition of endogenous miR-29a decreases glioblastoma growth and invasion in vitro and in vivo, and increased miR-29a expression in glioblastoma specimens correlates with decreased patient survival. Conclusions Taken together, these data identify miR-29a as a master regulator of glioblastoma growth and invasion.

Abstract
OBJECTIVE Neural stem cells (NSCs) are multipotent stem cells that generating various neural cells, including neurons, astrocytes and oligodendrocytes. This showed that NSCs is an ideal candidate in the application of neural disease treatment. In the current study, we established a simple and efficient method to promote the viability and induce the differentiation of NSCs by stimulating with magnesium. METHODS The proliferation and differentiation of NSCs was determined by MTT assay and immunostaining. The behavior alteration was measured by rotorod test and Morris water maze. RESULTS Magnesium enhanced proliferation in NSCs. The ratio of Nestin+, Ki67+ and GFAP+ progenitor cells was increased in the presence of magnesium. Besides, magnesium induced the glial differentiation instead of neuronal differentiation in NSCs. By contrast, transplantation of Mg2+-treated NSCs in vivo generated more neurons. In established PD models, transplantation of Mg2+-treated NSCs could improve the symptoms and recover the memory. CONCLUSION We established a simple and efficient way to promote the proliferation and induce the differentiation of NSCs. More importantly, this may also facilitate to develop a new method to neural disorder treatment.

Abstract
Myocardial ischemia-reperfusion (I/R) injury is thought to have its detrimental role in coronary heart disease (CHD), which is considered as the foremost cause of death all over the world. However, molecular mechanism in the progression of myocardial I/R injury is still unclear. The goal of this study was to investigate the expression and function of microRNA-140 (miR-140) in the process of myocardial I/R injury. The miR-140 expression level was analyzed in the myocardium with I/R injury and control myocardium using quantitative real-time polymerase chain reaction. Then the relation between the level of miR-140 and YES proto-oncogene 1 (YES1) was also investigated via luciferase reporter assay. Assessment of myocardial infarct size measurement of serum myocardial enzymes and electron microscopy analysis were used for analyzing the effect of miR-140 on myocardial I/R injury. We also used Western blot analysis to examine the expression levels of the mitochondrial fission-related proteins, Drp1 and Fis1. miR-140 is downregulated, and YES1 is upregulated after myocardial I/R injury. Overexpression of miR-140 could reduce the increase related to myocardial I/R injury in infarct size and myocardial enzymes, and it also could inhibit the expression of proteins related to mitochondrial morphology and myocardial I/R-induced mitochondrial apoptosis by targeting YES1. Taken together, these findings may provide a novel insight into the molecular mechanism of miR-140 and YES1 in the progression of myocardial I/R injury. MiR-140 might become a promising therapeutic target for treating myocardial I/R injury.
