Huang Y, Gu W, Qin Z, Jin Y. Bromuconazole exposure induces cardiac dysfunction by upregulating the expression LEF1. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 933:173113. [PMID: 38735319 DOI: 10.1016/j.scitotenv.2024.173113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 04/18/2024] [Accepted: 05/08/2024] [Indexed: 05/14/2024]
Abstract
With the wide application of bromuconazole (BRO), a kind of triazole fungicide, the environmental problems caused by BRO have been paid more and more attention. In this study, adult male zebrafish were exposed to environmental related concentration and the maximum non-lethal concentration for zebrafish larvae (0,50 ng/L and 7.5 mg/L) for 7 days, respectively. Zebrafish exposed to BRO exhibited a significant reduction in body length and an increase in fatness index, indicating adverse physiological changes. Notably, the exposed zebrafish showed enlarged heart ventricular volumes and thinner heart walls. Transcriptome analysis of heart samples showed that BRO exposure mainly affected pathways related to cardiac energy metabolism. In addition, the amount of ATP in the heart tissue was correspondingly reduced, and the expression levels of genes related to controlling ion balance and myosin synthesis in the heart were also altered. The study extended its findings to the rat cardiomyocytes (H9C2), where similar cardiotoxic effects including changes in transcription of genes related to energy metabolism and heart function were also observed, suggesting a potential universal mechanism of BRO-induced cardiotoxicity. In a doxorubicin (DOX) induced larval zebrafish heart failure model, the expression of lymphoid enhancer-binding factor 1(LEF1), a key gene in the Wnt/β-catenin signaling pathway, was significantly increased in larval zebrafish and adult fish heart tissues and cardiomyocytes, suggesting that LEF1 might play an important role in BRO-induced cardiotoxicity. Taken together, BRO exposure could interfere with cardiac function and metabolic capacity by abnormal activation the expression of LEF1. The study emphasized the urgent need for monitoring and regulating BRO due to its harmful effects on the hearts of aquatic organisms.

Abstract
This study aimed to investigate the molecular mechanisms underlying the protective effects of cyclooxygenase (cox) inhibitors against myocardial hypertrophy.Rat H9c2 cardiomyocytes were induced by mechanical stretching. SD rats underwent transverse aortic constriction to induce pressure overload myocardial hypertrophy. Rats were subjected to echocardiography and tail arterial pressure in 12W. qPCR and western blot were used to detect the expression of Notch-related signaling. The inflammatory factors were tested by ELISA in serum, heart tissue, and cell culture supernatant.Compared with control, levels of pro-inflammatory cytokines IL-6, TNF-α, and IL-1β were increased and anti-inflammatory cytokine IL-10 was reduced in myocardial tissues and serum of rat models. Levels of Notch1 and Hes1 were reduced in myocardial tissues. However, cox inhibitor treatment (aspirin and celecoxib), the improvement of exacerbated myocardial hypertrophy, fibrosis, dysfunction, and inflammation was parallel to the activation of Notch1/Hes1 pathway. Moreover, in vitro experiments showed that, in cardiomyocyte H9c2 cells, application of ~20% mechanical stretching activated inflammatory mediators (IL-6, TNF-α, and IL-1β) and hypertrophic markers (ANP and BNP). Moreover, expression levels of Notch1 and Hes1 were decreased. These changes were effectively alleviated by aspirin and celecoxib.Cox inhibitors may protect heart from hypertrophy and inflammation possibly via the Notch1/Hes1 signaling pathway.

Neuroepithelial cell-transforming 1 promotes cardiac fibrosis via the Wnt/β-catenin signaling pathway. iScience 2023; 26:107888. [PMID: 37766986 PMCID: PMC10520536 DOI: 10.1016/j.isci.2023.107888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 07/15/2023] [Accepted: 09/07/2023] [Indexed: 09/29/2023] Open
Abstract
This study found that the level of neuroepithelial cell-transforming gene 1 protein (NET1) was significantly increased in a mouse cardiac fibrosis model. Moreover, the expression level of NET1 was increased in cardiac fibrosis induced by TGF-β1, suggesting that NET1 was involved in the pathological process of cardiac fibrosis. Overexpression of NET1 promoted β-catenin expression in the nucleus and significantly increased the proliferation and migration of cardiac fibroblasts. NET1 may form a complex with β-catenin through GSK3β. Knockdown of β-catenin alleviated the effects of NET1 overexpression on collagen production and cell migration. In the heart of NET1 knockout mice, NET1 knockout can reduce the expression of β-catenin, α-SMA, and collagen content induced by MI. In conclusion, NET1 may regulate the activation of Wnt/β-catenin and TGF/Smads signaling pathway, promote collagen synthesis in fibroblasts, and participate in cardiac fibrosis. Thus, NET1 may be a potential therapeutic target in cardiac fibrosis.

Abstract
The release of inflammatory cytokines, namely tumor necrosis factor-α (TNF-α), plays an important role in the pathogenesis of cardiomyopathy. TNF-α increases in plasma and in myocardium of heart failure patients. We aimed to investigate the role of TNF-α inhibitor (infliximab; IFX) in regulating dilated cardiomyopathy (DCM) induced in rats. DCM was induced in rats by doxorubicin (DOX; 3.5 mg. kg-1 , i.p) twice weekly for 3 weeks (21 mg. kg-1 cumulative dose). DCM rats were treated with RPL (1 mg. kg-1 orally, daily), IFX (5 mg. kg-1 ; i.p. once) or their combination for 4 weeks starting next day of last DOX dose. Echocardiography was conducted followed by a collection of blood and left ventricle (LV) for biochemical and histological investigations. DCM rats revealed deteriorated cardiac function (increased CK-MB activity, LVIDs, LVIDd, ESV, and EDV, while decreased EF% and FS%), hypertrophy (increased HW/TL, β-MHC, and α-actin), inflammation (increased IL-1β, IL-6, and TNF-α). The activation of Wnt/β-catenin along with increased gene expression of RAS components (RENIN, ACE, and AT1) were evident. LV architecture also revealed abnormalities and some degree of fibrosis. Treatment with RPL and/or IFX suppressed TNF-α and consequently improved most of these parameters suppressing Wnt/β-catenin/RAS axis. Combined RPL and IFX treatment was the best among all treatments. In conclusion, Wnt/β-catenin/RAS axis is implicated in DOX-induced cardiomyopathy. The upstream TNF-α was proved for the first time in-vivo to stimulate this axis where its inhibition by RPL or IFX prevented DCM. Targeting this axis at two points using RPL and IFX showed better therapeutic efficacy.

Abstract
Myocardial hypertrophy (MH) is an independent risk factor for cardiovascular disease, which in turn lead to arrhythmia or heart failure. Therefore, attention must be paid to formulation of therapeutic strategies for MH. Puerarin is a key bioactive ingredient isolated from Pueraria genera of plants that is beneficial for the treatment of MH. However, its molecular mechanism of action has not been fully determined. In the present study, 40 µM puerarin was demonstrated to be a safe dose for human AC16 cells using Cell Counting Kit‑8 assay. The protective effects of puerarin against MH were demonstrated in AC16 cells stimulated with isoproterenol (ISO). These effects were characterized by a significant decrease in surface area of cells (assessed using fluorescence staining) and mRNA and protein expression levels of MH‑associated biomarkers, including atrial and brain natriuretic peptide, assessed using reverse transcription‑quantitative PCR and western blotting, as well as β‑myosin heavy chain mRNA expression levels. Mechanistically, western blotting demonstrated that puerarin inhibited activation of the Wnt signaling pathway. Puerarin also significantly decreased phosphorylation of p65; this was mediated via crosstalk between the Wnt and NF‑κB signaling pathways. An inhibitor (Dickkopf‑1) and activator (IM‑12) of the Wnt signaling pathway were used to demonstrate that puerarin‑mediated effects alleviated ISO‑induced MH via the Wnt signaling pathway. The results of the present study demonstrated that puerarin pre‑treatment may be a potential therapeutic strategy for preventing ISO‑induced MH and managing MH in the future.

Abstract
Calcium dysregulation and mitochondrial dysfunction are key elements in the development of sepsis-induced cardiac dysfunction. Evidences have suggested that inhibition of Wnt/β-Catenin signalling prevents cardiac dysfunction and remodelling in surgical, hypertension and pressure overload models. The present study investigated the effects of Wnt/β-Catenin inhibitor on calcium overload and mitochondrial dysfunction in rat sepsis model of cardiomyopathy. Induction of sepsis by cecal ligation puncture (CLP) resulted in the up-regulation of cardiac β-catenin transcriptional levels and cardiac dysfunction depicted by increased serum lactate dehydrogenase, CK-MB levels reduced maximum (dp/dt max.) and minimum developed pressure (dp/dt min.), increased LVEsDP and relaxation constant tau values. Moreover, oxidative and inflammatory stress, immune cell infiltration, increased myeloperoxidase activity, enhanced caspase-3 activity and fibronectin protein levels were observed in septic rat's heart. Also, septic rat's heart displayed mitochondrial dysfunction due to mPTP opening, increased calcium up-regulation in left ventricular apex tissues and whole heart, increased collagen staining, necrosis and structural damage. Pre-treatment with Wnt/β-Catenin antagonist attenuated sepsis-induced serum and tissue biochemical changes, cardiac dysfunction and structural alterations by inhibiting mitochondrial mPTP opening and restricting calcium overloading in cardiac tissue.

Abstract
The Wnt signaling pathway regulates physiological processes such as cell proliferation and differentiation, cell fate decisions, and stem cell maintenance and, thus, plays essential roles in embryonic development, but also in adult tissue homeostasis and repair. The Wnt signaling pathway has been associated with heart development and repair and has been shown to be crucially involved in proliferation and differentiation of progenitor cells into cardiomyocytes. The investigation of the role of the Wnt signaling pathway and the regulation of its expression/activity in atrial fibrillation has only just begun. The present minireview (I) provides original data regarding the expression of Wnt signaling components in atrial tissue of patients with atrial fibrillation or sinus rhythm and (II) summarizes the current state of knowledge of the regulation of Wnt signaling components' expression/activity and the contribution of the various levels of the Wnt signal transduction pathway to the processes of the development, maintenance, and progression of atrial fibrillation.

Abstract
Background Cardiac hypertrophy usually results in heart failure and is an important cause of mortality worldwide. Wnt/β-catenin signaling pathway hyper-activation is involved in the pathogenesis and progression of cardiac hypertrophy. Wnt-C59 is a small molecular compound, which strongly and specifically targets at Porcupine to pharmacologically inhibit Wnt palmitoylation, secretion, and other biological activities. However, the role of Wnt-C59 in cardiac hypertrophy remains unknown. Material/Methods We performed transverse aortic constriction (TAC) in adult male mice to induce pressure overload and establish an in vivo model of cardiac hypertrophy. Angiotensin II (Ang-II) was utilized to culture cardiomyocyte to establish a model of in vitro cardiomyocyte hypertrophy. Daily administration of Porcupine inhibitor Wnt-C59 was performed for 4 weeks after TAC surgery. Results Wnt-C59 significantly improved cardiac function and enhanced survival of mice subjected to TAC surgery. Histologically, Wnt-C59 attenuated TAC-induced increase in heart mass, cross-section area of cardiomyocyte, cardiac fibrosis, cardiomyocyte apoptosis, and expression of the hypertrophic biomarkers β-MHC, ANP, and BNP. TAC-induced oxidative stress was also ameliorated by Wnt-C59. Wnt-C59 attenuated Ang-II-induced in vitro cardiomyocyte hypertrophy, as indicated by decreased cell size and lower expression of ANP, BNP, and β-MHC. Moreover, Wnt/β-catenin activation was blocked by Wnt-C59 in cardiac hypertrophy, as indicated by decreased protein expression of Wnt3a and β-catenin and the Wnt target genes cyclin D1 and c-Myc. Conclusions Collectively, Porcupine inhibitor Wnt-C59 attenuates pressure overload-induced cardiac hypertrophic via interruption of the Wnt/β-catenin signaling pathway, and it might be a promising drug for patients with cardiac hypertrophy.

Abstract
AIMS Cardiac hypertrophy is one of most important risk factors for cardiovascular mortality. Activation of Wnt/β-catenin signaling pathway is acknowledged to be an important mechanism for pathogenesis of cardiac hypertrophy. Polyphyllin I (PPI), a component in the traditional Chinese medicinal herb, has shown anticancer effect partially via interruption of Wnt/β-catenin signaling pathway. Our aim was to test whether PPI attenuates cardiac hypertrophy. MATERIALS AND METHODS Adult male C57BL/6J mice were subjected to either pressure overload generated by transverse aortic constriction (TAC) or sham surgery (control group). Angiotensin-II (Ang-II) was used to induce cardiomyocyte hypertrophy in vitro. PPI was intraperitoneally administrated daily for 4 weeks after TAC surgery and then cardiac function was determined by echocardiography and histological analysis was performed. KEY FINDINGS PPI significantly ameliorated cardiac dysfunction of mice subjected to TAC. Meanwhile, PPI attenuated TAC induced cardiac hypertrophy indicated by blunted increase in heart mass, cross section area of cardiomyocyte, cardiac fibrosis and expression of hypertrophic biomarkers ANP, BNP and β-MHC. In addition, PPI also ameliorated Ang-II induced cardiomyocyte hypertrophy in vitro. Importantly, PPI decreased protein expression of active β-catenin/total β-catenin, phosphorylation of GSK3β and Wnt target genes c-myc, c-jun, c-fos and cyclin D1 and its anti-hypertrophic effect was blunted by supplementation of Wnt 3a. SIGNIFICANCE Our results suggest that PPI attenuates cardiac dysfunction and attenuate development of pressure over-load induced cardiac hypertrophic via suppressing Wnt/β-catenin signaling pathway. PPI might be a candidate drug for treatment of cardiac hypertrophy.

Abstract
Cytochrome P450 (P450) enzymes are superfamily of monooxygenases that hold the utmost diversity of substrate structures and catalytic reaction forms amongst all other enzymes. P450 enzymes metabolize arachidonic acid (AA) to a wide array of biologically active lipid mediators. P450-mediated AA metabolites have a significant role in normal physiological and pathophysiological conditions, hence they could be promising therapeutic targets in different disease states. P450 monooxygenases mediate the (ω-n)-hydroxylation reactions, which involve the introduction of a hydroxyl group to the carbon skeleton of AA, forming subterminal hydroxyeicosatetraenoic acids (HETEs). In the current review, we specified different P450 isozymes implicated in the formation of subterminal HETEs in varied tissues. In addition, we focused on the role of subterminal HETEs namely 19-HETE, 16-HETE, 17-HETE and 18-HETE in different organs, importantly the kidneys, heart, liver and brain. Furthermore, we highlighted their role in hypertension, acute coronary syndrome, diabetic retinopathy, non-alcoholic fatty liver disease, ischemic stroke as well as inflammatory diseases. Since each member of subterminal HETEs exist as R and S enantiomer, we addressed the issue of stereoselectivity related to the formation and differential effects of these enantiomers. In conclusion, elucidation of different roles of subterminal HETEs in normal and disease states leads to identification of novel therapeutic targets and development of new therapeutic modalities in different disease states.

Abstract
Development of cardiomyopathy (CM) is dependent upon several factors. However, the reaction of the immune response against myocardial tissue due to microbial and viral infections plays an important role in this disease. Therefore, the purpose of this study is to investigate the relationship between HLAs and their pathogenic mechanisms in the incidence of CM. Relevant literature was identified by a PubMed search (1989-2017) of English-language papers using the terms "Cardiomyopathy", "Human leukocyte antigen or HLA", "immune response", and "polymorphism". If CM patients are afflicted with viral and microbial infections, HLA class II molecules, which are not expressed on myocardial tissue in normal conditions, are mainly expressed on it. As a result, these HLAs present self- antigens and provoke autoimmune responses against myocardial tissue. On the other hand, the occurrence of polymorphism as well as disrupted expression of miRNAs can affect HLA expression, leading to hypertrophy and fibrosis of cardiac muscle. Finally, it is inferred that the expression evaluation of HLAs as well as identification of polymorphisms in their coding genes can be effective diagnostic factors in the detection of people susceptible to CM.

Abstract
The liver abundantly expresses various drug-metabolizing enzymes and, thus, plays a central role in drug metabolism. In this regard, cytochrome P450 (CYP) is responsible for drug metabolism in the liver. Therefore, since CYP3A4 accounts for approximately 30% of the CYPs, the prediction of hepatic CYP3A4-mediated pharmacokinetics is essential for drug development. Human induced pluripotent stem cell-derived hepatocytes (hiHep) have become a major model of drug metabolism in drug development studies. However, drug metabolizing activities, such as those involving CYP3A4, are lower in hiHep than in human primary hepatocytes (HPHs). Recently, it was revealed that celecoxib upregulates the expression of CYPs to normal levels through the activation of signal transducer and transcriptional activation factor 5 (STAT5). Therefore, we investigated whether celecoxib treatment could normalize the low drug metabolism activities in hiHep. The mRNA expression levels of hepatic markers [asialoglycoprotein receptor 1 (ASGR1) and tyrosine aminotransferase (TAT)] and metabolic enzymes (UDP-glucuronosyltransferase 1A1 and CYP3A4) in hiHep significantly increased after celecoxib treatment. These mRNA expression levels were 7-, 1/3-, 1/2-, and 1/10-fold of the HPHs cultured for 48 hours, respectively. Furthermore, CYP3A4 activity significantly increased. To investigate the mechanism of CYP3A4 mRNA upregulation, we analyzed the phosphorylation of STAT5 after celecoxib treatment and found it to be significantly increased. Moreover, the increase in CYP3A4 mRNA expression was attenuated by cotreatment with STAT5 inhibitor. These results suggest that celecoxib promotes hepatocyte differentiation of hiHep by activating STAT5 and is useful for the generation of functional hiHep.

An essential role for Wnt/β-catenin signaling in mediating hypertensive heart disease. Sci Rep 2018; 8:8996.

Abstract
Activation of the renin-angiotensin system (RAS) is associated with hypertension and heart disease. However, how RAS activation causes cardiac lesions remains elusive. Here we report the involvement of Wnt/β-catenin signaling in this process. In rats with chronic infusion of angiotensin II (Ang II), eight Wnt ligands were induced and β-catenin activated in both cardiomyocytes and cardiac fibroblasts. Blockade of Wnt/β-catenin signaling by small molecule inhibitor ICG-001 restrained Ang II-induced cardiac hypertrophy by normalizing heart size and inhibiting hypertrophic marker genes. ICG-001 also attenuated myocardial fibrosis and inhibited α-smooth muscle actin, fibronectin and collagen I expression. These changes were accompanied by a reduced expression of atrial natriuretic peptide and B-type natriuretic peptide. Interestingly, ICG-001 also lowered blood pressure induced by Ang II. In vitro, Ang II induced multiple Wnt ligands and activated β-catenin in rat primary cardiomyocytes and fibroblasts. ICG-001 inhibited myocyte hypertrophy and Snail1, c-Myc and atrial natriuretic peptide expression, and abolished the fibrogenic effect of Ang II in cardiac fibroblasts. Finally, recombinant Wnt3a was sufficient to induce cardiomyocyte injury and fibroblast activation in vitro. Taken together, these results illustrate an essential role for Wnt/β-catenin in mediating hypertension, cardiac hypertrophy and myocardial fibrosis. Therefore, blockade of this pathway may be a novel strategy for ameliorating hypertensive heart disease.

Resveratrol Co-Treatment Attenuates the Effects of HIV Protease Inhibitors on Rat Body Weight and Enhances Cardiac Mitochondrial Respiration. PLoS One 2017; 12:e0170344.

Abstract
Since the early 1990s human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) emerged as a global health pandemic, with sub-Saharan Africa the hardest hit. While the successful roll-out of antiretroviral (ARV) therapy provided significant relief to HIV-positive individuals, such treatment can also elicit damaging side-effects. Here especially HIV protease inhibitors (PIs) are implicated in the onset of cardio-metabolic complications such as type-2 diabetes and coronary heart disease. As there is a paucity of data regarding suitable co-treatments within this context, this preclinical study investigated whether resveratrol (RSV), aspirin (ASP) or vitamin C (VitC) co-treatment is able to blunt side-effects in a rat model of chronic PI exposure (Lopinavir/Ritonavir treatment for 4 months). Body weights and weight gain, blood metabolite levels (total cholesterol, HDL, LDL, triglycerides), echocardiography and cardiac mitochondrial respiration were assessed in PI-treated rats ± various co-treatments. Our data reveal that PI treatment significantly lowered body weight and cardiac respiratory function while no significant changes were found for heart function and blood metabolite levels. Moreover, all co-treatments ameliorated the PI-induced decrease in body weight after 4 months of PI treatment, while RSV co-treatment enhanced cardiac mitochondrial respiratory capacity in PI-treated rats. This pilot study therefore provides novel hypotheses regarding RSV co-treatment that should be further assessed in greater detail.

Klotho inhibits angiotensin II-induced cardiomyocyte hypertrophy through suppression of the AT1R/beta catenin pathway. Biochem Biophys Res Commun 2016; 473:455-61.

Abstract
Myocardial hypertrophy is an independent risk factor for cardiac morbidity and mortality. The antiaging protein klotho reportedly possesses a protective role in cardiac diseases. However, the precise mechanisms underlying the cardioprotective effects of klotho remain unknown. This study was aimed to determine the effects of klotho on angiotensin II (Ang II)-induced hypertrophy in neonatal rat cardiomyocytes and the possible mechanism of actions. We found that klotho significantly inhibited Ang II-induced hypertrophic growth of neonatal cardiomyocytes, as evidenced by decreased [(3)H]-Leucine incorporation, cardiomyocyte surface area and β-myosin heavy chain (β-MHC) mRNA expression. Meanwhile, klotho inhibited Ang II-stimulated activation of the Wnt/β-catenin pathway in cardiomyocytes, as evidenced by decreased protein expression of active β-catenin, downregulated protein and mRNA expression of the β-catenin target genes c-myc and cyclin D1, and increased β-catenin phosphorylation. Inhibition of the Wnt/β-catenin pathway by the specific inhibitor XAV939 markedly attenuated Ang II-induced cardiomyocyte hypertrophy. The further study revealed that klotho treatment significantly downregulated protein expression of Ang II receptor type I (AT1R) but not type II (AT2R). The AT1R antagonist losartan inhibited Ang II-stimulated activation of the Wnt/β-catenin pathway and cardiomyocyte hypertrophy. Our findings suggest that klotho inhibits Ang II-induced cardiomyocyte hypertrophy through suppression of the AT1R/β-catenin signaling pathway, which may provide new insights into the mechanism underlying the protective effects of klotho in heart diseases, and raise the possibility that klotho may act as an endogenous antihypertrophic factor by inhibiting the Ang II signaling pathway.
