Biomedicines 2024; 12:1314. [PMID: 38927520 PMCID: PMC11201699 DOI: 10.3390/biomedicines12061314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 05/08/2024] [Accepted: 06/11/2024] [Indexed: 06/28/2024] Open
Abstract
Myocardial infarction (MI) often leads to heart failure (HF) through acute or chronic maladaptive remodeling processes. This establishes coronary artery disease (CAD) and HF as significant contributors to cardiovascular illness and death. Therefore, treatment strategies for patients with CAD primarily focus on preventing MI and lessening the impact of HF after an MI event. Myocardial fibrosis, characterized by abnormal extracellular matrix (ECM) deposition, is central to cardiac remodeling. Understanding these processes is key to identifying new treatment targets. Recent studies highlight SGLT2 inhibitors (SGLT2i) and GLP-1 receptor agonists (GLP1-RAs) as favorable options in managing type 2 diabetes due to their low hypoglycemic risk and cardiovascular benefits. This review explores inflammation's role in cardiac fibrosis and evaluates emerging anti-diabetic medications' effectiveness, such as SGLT2i, GLP1-RAs, and dipeptidyl peptidase-4 inhibitors (DPP4i), in preventing fibrosis in patients with diabetes post-acute MI. Recent studies were analyzed to identify effective medications in reducing fibrosis risk in these patients. By addressing these areas, we can advance our understanding of the potential benefits of anti-diabetic medications in reducing cardiac fibrosis post-MI and improve patient outcomes in individuals with diabetes at risk of HF.

Effect of GLP-1 Receptor Agonist on Ischemia Reperfusion Injury in Rats with Metabolic Syndrome. Pharmaceuticals (Basel) 2024; 17:525. [PMID: 38675485 PMCID: PMC11053642 DOI: 10.3390/ph17040525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/14/2024] [Accepted: 04/15/2024] [Indexed: 04/28/2024] Open
Abstract
Metabolic syndrome (MetS) represents an important factor that increases the risk of myocardial infarction, and more severe complications. Glucagon Like Peptide-1 Receptor Agonists (GLP-1RAs) exhibit cardioprotective potential, but their efficacy in MetS-related myocardial dysfunction has not been fully explored. Therefore, we aimed to assess the effects of exenatide and dulaglutide on heart function and redox balance in MetS-induced rats. Twenty-four Wistar albino rats with induced MetS were divided into three groups: MetS, exenatide-treated (5 µg/kg), dulaglutide-treated (0.6 mg/kg). After 6 weeks of treatment, in vivo heart function was assessed via echocardiography, while ex vivo function was evaluated using a Langendorff apparatus to simulate ischemia-reperfusion injury. Heart tissue samples were analyzed histologically, and oxidative stress biomarkers were measured spectrophotometrically from the coronary venous effluent. Both exenatide and dulaglutide significantly improved the ejection fraction by 3% and 7%, respectively, compared to the MetS group. Histological analyses corroborated these findings, revealing a reduction in the cross-sectional area of cardiomyocytes by 11% in the exenatide and 18% in the dulaglutide group, indicating reduced myocardial damage in GLP-1RA-treated rats. Our findings suggest strong cardioprotective potential of GLP-1RAs in MetS, with dulaglutide showing a slight advantage. Thus, both exenatide and dulaglutide are potentially promising targets for cardioprotection and reducing mortality in MetS patients.

Abstract
Amaç: Mezenkimal kök hücreler, çeşitli protokoller kullanılarak in vitro koşullarda kolaylıkla
kardiyomiyositlere farklılaşabilir. Ancak bu protokollerde kullanılan ajanların hücre canlılığı üzerinde bazı
olumsuz etkileri olduğu bildirilmiştir. Azasitidin mezenkimal kök hücreleri kalp kası hücrelerine
farklandırmak için kullanılmaktadır. Bu çalışmanın amacı, bir GLP-1 reseptör agonisti olan Eksenatid'in
insan yağ dokusu kaynaklı kök hücrelerinin kardiyomiyositlere farklılaşması ve canlılığı üzerindeki
etkilerini araştırmaktır.
Gereç ve Yöntem: Azasitidin ve Eksenatid'in insan yağ doku kaynaklı mezenkimal kök hücreler
üzerinde hücre canlılığı ve proliferasyonu üzerindeki etkileri ile sitotoksisite testleri yapıldı. Farklılanma
protokolü için, hücreler dört hafta boyunca Azasitidin ve Eksenatid ile inkübe edildi. Hücrelerin morfolojik
değişiklikleri izlendi ve kardiyomiyojenik farklılaşma belirteçlerinin (cTnI, GATA4 ve MYH7)
ekspresyonları immünohistokimyasal olarak değerlendirildi. Ayrıca kültürlerdeki kardiyak troponin I
(cTnI) seviyeleri enzime bağlı immünosorbent testi kullanılarak ölçüldü. Veriler, tek yönlü varyans analizi
(ANOVA) ve post-hoc testi ile değerlendirildi.
Bulgular: İnsan yağ doku kaynaklı mezenkimal kök hücreler üzerine Azasitidin uygulaması, kontrole
grubuna kıyasla hücre canlılığını önemli ölçüde azaltırken (%54.4) hücrelerin Azasitidin+Eksenatid ile
uygulaması doza bağlı bir şekilde hücre ölümünü önledi. Azasitidin ve Eksenatid uygulanan hücreler,
kardiyomiyojenik farklılaşma ile uyumlu önemli morfolojik değişiklikler ve kardiyomiyojenik belirteçlerde
artış gösterdi. Ayrı ayrı ve birlikte uygulama yapılan gruplarda cTnI seviyeleri kontrole göre anlamlı
derecede yüksek bulundu.
Sonuç: Bu bulgular GLP-1 reseptör agonisti Eksenatid'in, Azasitidin uygulamasının neden olduğu hücre
hasarını azaltarak İnsan yağ doku kaynaklı mezenkimal kök hücrelerin kardiyomiyojenik farklılaşması
üzerinde faydalı etkileri olabileceğini düşündürmektedir.

Abstract
Fibrosis can occur in various organs, leading to structural destruction, dysfunction, and even organ failure. Hence, organ fibrosis is being actively researched worldwide. Glucagon-like peptide-1 (GLP-1), a naturally occurring hormone, binds to a G-protein-coupled receptor widely distributed in the pancreas, kidney, lung, heart, gastrointestinal tract, and other organs. Synthetic GLP-1 analogs can be used as GLP-1 receptor agonists (GLP-1RAs) for treating diabetes mellitus. In recent years, GLP-1RAs have also been found to exert anti-inflammatory, antioxidant, and cardiovascular protective effects. GLP-1RAs have also been shown to inhibit fibrosis of solid organs, such as the lung, heart, liver, and kidney. In this review, we discuss the advancements in research on the role of GLP-1RAs in the fibrosis of the heart, lung, liver, kidney, and other organs to obtain new clues for treating organ fibrosis.

Abstract
A series of polyethylenimine (PEI)-based CQDs have been synthesized via a hydrothermal method by mixing linear PEI with linear citric acid (CA with COOH groups, PEICA), linear glucose (G with OH groups, PEIG), cyclic hyaluronic acid (HA with COOH groups, PEIHA) and cyclic boron nitride (BN with OH groups, PEIBN). PEICA had the best labeling effect (100.00 ± 0.26%) and the lowest cytotoxicity (100.89 ± 18.00%) for mesenchymal stem cells (MSCs), followed by PEIG (91.83 ± 7.60%; 92.84 ± 5.56%), PEIHA (84.34 ± 7.87%; 61.27 ± 11.34%) and PEIBN (1.33 ± 0.84%; 22.72 ± 11.47%). The labeling effect of PEIHA for MSCs is lower than that of PEIG because the surface potential of PEIHA (6.58 mV) is higher than that of PEIG (0.50 mV). For PEIBN, it is likely that the precursor (BN) is less biocompatible than CA, HA and glucose. Thus, the linear acid (CA) is more appropriate to react with PEI for synthesizing CQDs with high labeling performance for MSCs. The control experimental results show that factors (such as surface potential, aromatic component, etc.) may all contribute to MSC labeling by PEICA. This work is helpful to design CQDs with high MSC labeling efficiency.

Abstract
Introduction Mesenchymal stem cells (MSCs) are a promising resource for tissue regeneration and repair. However, their clinical application is hindered by technical limitations related to MSC enrichment at the target sites. Methods MSCs were labeled with magnetic Fe3O4 nanoparticles (NPs). We analyzed the effects of NP on cell proliferation, stem cell characteristics, and cytokine secretion. Furthermore, we induced NP-labeled MSC migration with an external magnetic field toward laser-induced skin wounds in rats and evaluated the associated anti-inflammatory effects. Results Fe3O4 NP application did not adversely affect MSC characteristics. Moreover, Fe3O4 NP-labeled MSCs presented increased anti-inflammatory cytokine and chemokine production compared with unlabeled MSCs. Furthermore, MSCs accumulated at the injury site and magnetic targeting promoted NP-labeled MSC migration toward burn injury sites in vivo. On day 7 following MSC injection, reduced inflammation and promoted angiogenesis were observed in the magnetically targeted MSC group. In addition, anti-inflammatory factors were upregulated, whereas pro-inflammatory factors were downregulated within the magnetically targeted MSC group compared with those in the PBS group. Conclusion This study demonstrates that magnetically targeted MSCs contribute to cell migration to the site of skin injury, improve anti-inflammatory effects and enhance angiogenesis compared with MSC injection alone. Therefore, magnetically targeted MSC therapy may be an effective treatment approach for epithelial tissue injuries.

Abstract
Myocardial infarction (MI) is one of the leading causes of death worldwide. Mesenchymal stem cell (MSC) transplantation is considered a promising approach and has made significant progress in preclinical studies and clinical trials for treating MI. However, hurdles including poor survival, retention, homing, and differentiation capacity largely limit the therapeutic effect of transplanted MSCs. Many strategies such as preconditioning, genetic modification, cotransplantation with bioactive factors, and tissue engineering were developed to improve the survival and function of MSCs. On the other hand, optimizing the hostile transplantation microenvironment of the host myocardium is also of importance. Here, we review the modifications of MSCs as well as the host myocardium to improve the efficacy of MSC-based therapy against MI.

Abstract
Epidemiological evidence supports a reduced prevalence of Thoracic Aortic Aneurysm (TAA) and Abdominal Aortic Aneurysm (AAA) in patients with Diabetes (DM). The mechanisms underlying this negative association are unknown. Some studies support that hyperglycemia has effects on the Extracellular Matrix (ECM), resulting in collagen cross-links and altered proteolytic activity, which ultimately counteracts aneurysm formation. However, recent experimental research indicates that incretin- based anti-diabetic therapy and Glucagon-Like Peptide-1 (GLP-1) may reduce the formation of TAA. GLP-1 is a peptide hormone, released from intestinal L-cells in response to hormonal, neural and nutrient stimuli. In addition to potentiation of meal-stimulated insulin secretion, GLP-1 signaling exerts numerous pleiotropic effects on various tissues, including protective effects on the myocardium and vascular endothelium. Recent studies also report protective effects of GLP-1 based therapy on the formation of aneurysms in animal models and direct effects of GLP-1 signaling on the molecular mechanisms suggested to influence TAA formation, including inflammation, proteolytic activity and collagen composition. In this narrative review, we present the available evidence for effects of GLP-1 on experimental aneurysm development and discuss the potential role of GLP-1 in aneurysm formation based on available data from pre-clinical and clinical studies.

Abstract
Mitochondrial injury and defective autophagy are common in diabetic cardiomyopathy. Recent evidence supports benefits of glucagon-like peptide-1 (GLP-1) agonists exendin-4 (Exe) and liraglutide (LIRA) against diabetic cardiomyopathy. This study was designed to examine the effect of Exe and LIRA on glucose-induced cardiomyocyte and mitochondrial injury, oxidative stress, apoptosis, and autophagy change. Cardiomyocytes isolated from adult mice and H9c2 myoblast cells were exposed to high glucose (HG, 33 mM) with or without Exe or LIRA. Cardiac contractile properties were assessed including peak shortening, maximal velocity of shortening/relengthening (±dL/dt), time to PS, and time-to-90% relengthening (TR90). Superoxide levels, apoptotic proteins such as cleaved caspase-3, Bax, and Bcl-2, and autophagy proteins including Atg5, p62, Beclin-1, LC3B, and mTOR/ULK1 were evaluated using Western blot. Mitochondrial membrane potential (MMP) changes were assessed using JC-1, and autophagosomes were determined using GFP-LC3. Cardiomyocyte exposure to HG exhibited prolonged TR90 associated with significantly decreased PS and ±dL/dt, the effects of which were partly restored by GLP-1 agonists, the effects of which were negated by the mTOR activator 3BDO. H9c2 cell exposure to HG showed increased intracellular ROS, apoptosis, MMP loss, dampened autophagy, and elevated p-mTOR and p-ULK1, the effects of which were nullified by the GLP-1 agonists. These results suggested that GLP-1 agonists rescued glucose toxicity likely through induction of mTOR-dependent autophagy.

Novel insights into cardiomyocytes provided by atomic force microscopy. Semin Cell Dev Biol 2017; 73:4-12. [PMID: 28687239 DOI: 10.1016/j.semcdb.2017.07.003] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2017] [Revised: 06/29/2017] [Accepted: 07/03/2017] [Indexed: 01/04/2023]
Abstract
Cardiovascular diseases (CVDs) are the number one cause of death globally, therefore interest in studying aetiology, hallmarks, progress and therapies for these disorders is constantly growing. Over the last decades, the introduction and development of atomic force microscopy (AFM) technique allowed the study of biological samples at the micro- and nanoscopic level, hence revealing noteworthy details and paving the way for investigations on physiological and pathological conditions at cellular scale. The present work is aimed to collect and review the literature on cardiomyocytes (CMs) studied by AFM, in order to emphasise the numerous potentialities of this approach and provide a platform for researchers in the field of cardiovascular diseases. Original data are also presented to highlight the application of AFM to characterise the viscoelastic properties of CMs.
