Congestive heart failure model representing aortic banding induced hypertrophy: A study to analyse extent of pressure overload and alteration in myocardial structure and function. IJC HEART & VASCULATURE 2021; 34:100755. [PMID: 33816767 PMCID: PMC8008182 DOI: 10.1016/j.ijcha.2021.100755] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 03/04/2021] [Accepted: 03/05/2021] [Indexed: 11/23/2022]
Abstract
Congestive Heart failure (CHF) is a severe pathology representing a major public health problem in industrialized nations which is increasing in prevalence and incidence. The aortic banding rat model provides steady progression of cardiac dysfunction under chronic pressure overload. Present study evaluated two abdominal aortic constriction techniques including constriction of aorta above renal arteries and between renal arteries. The extent of constriction was varied with 22 G and 24 G needles and the duration for evaluation of CHF was also varied by terminating the banded animals after 6 and 8 weeks of banding. Various hemodynamic, ECG and tissue parameters were evaluated after banding to see the progression of CHF. The findings revealed that the constriction of the aorta above both renal arteries with 24 G needle is a better technique amongst other tested banding techniques as the rate of progression of CHF was found to be maximum with it. On the basis of above study, it was concluded that, aortic banding above both renal arteries with 24 G needle is a better technique for induction of pressure overload and for further observation in transition of the cardiac compensatory to decompensatory phase, the duration of the model needs to be prolonged.

Abstract
Comprehensively understanding pharmacological functions of natural products is a key issue to be addressed for the discovery of new drugs. Unlike some single-target drugs, natural products always exert diverse therapeutic effects through acting on a "network" that consists of multiple targets, making it necessary to develop a systematic approach, e.g., network pharmacology, to reveal pharmacological functions of natural products and infer their mechanisms of action. In this work, to identify the "network target" of a natural product, we perform a functional analysis of matrine, a marketed drug in China extracted from a medical herb Ku-Shen (Radix Sophorae Flavescentis). Here, the network target of matrine was firstly predicted by drugCIPHER, a genome-wide target prediction method. Based on the network target of matrine, we performed a functional gene set enrichment analysis to computationally identify the potential pharmacological functions of matrine, most of which are supported by the literature evidence, including neurotoxicity and neuropharmacological activities of matrine. Furthermore, computational results demonstrated that matrine has the potential for the induction of macropinocytosis and the regulation of ATP metabolism. Our experimental data revealed that the large vesicles induced by matrine are consistent with the typical characteristics of macropinosome. Our verification results also suggested that matrine could decrease cellular ATP level. These findings demonstrated the availability and effectiveness of the network target strategy for identifying the comprehensive pharmacological functions of natural products.

Abstract
Matrine is a widely used Chinese herbal medicine that has historically been used in the treatment of inflammation and cancer. However, the antimetastatic effects and associated molecular mechanisms of matrine on nasopharyngeal carcinoma (NPC) remain to be elucidated. Therefore, the aims of the present study were to assess the antimetastatic effects of matrine on NPC, and identify the underlying mechanisms. Matrine inhibited the proliferation of NPC cells in vitro and in vivo. Furthermore, matrine inhibited the migration and invasion of NPC tumor cells at doses below the toxic range. Following treatment with matrine for 24 h, there was a decrease in the protein expression levels and activities of matrix metalloproteinase (MMP)‑2 and MMP‑9 in NPC‑039 cells. In addition, matrine markedly reduced the expression levels of p65 and p50 in the nuclei. Combined treatment of matrine with helenalin, a nuclear factor‑κB (NF‑κB) inhibitor resulted in a synergistic reduction in MMP‑2 and MMP‑9 expression levels, and the invasive capabilities of the NPC‑039 cells were also reduced. In conclusion, matrine inhibits NPC cell migration and invasion by suppressing the NF‑κB pathway. These results suggest that matrine may be a potential therapeutic agent for NPC.

J Mol Med (Berl) 2015; 93:663-74. [PMID: 25595602 DOI: 10.1007/s00109-015-1251-9] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2014] [Revised: 12/15/2014] [Accepted: 01/06/2015] [Indexed: 01/22/2023]
Abstract
UNLABELLED Left ventricular (LV) function influences outcomes in right ventricular (RV) failure. Carvedilol reduces mortality in LV failure and improves RV function in experimental pulmonary arterial hypertension (PAH). However, its impact on ventricular-ventricular interactions and LV function in RV afterload is unknown. We investigated effects of carvedilol on biventricular fibrosis and function in a rat model of persistent PAH. Rats were randomized into three groups: Sham controls, PAH, and PAH + carvedilol. Severe PAH was induced by 60 mg/kg subcutaneous monocrotaline. In the treatment group, oral carvedilol (15 mg/kg/day) was started 2 weeks after monocrotaline injection and continued for 3 weeks until the terminal experiment. Echocardiography and exercise performance were performed at baseline and repeated at the terminal experiment with hemodynamic measurements. LV and RV myocardium were analyzed for hypertrophy, fibrosis, and molecular signaling by protein and mRNA analysis. PAH and PAH + carvedilol rats experienced severely elevated pulmonary arterial pressures and RV hypertrophy. Despite similar RV systolic pressures, carvedilol reduced biventricular collagen content (RV fibrosis area; 13.4 ± 6.5 vs. 5.5 ± 2.7 %, p < 0.001) and expression of transforming growth factor-β1 (TGFβ1) (RV TGFβ1/glyceraldehyde 3-phosphate dehydrogenase (GAPDH) ratio; 1.16 ± 0.39 vs. 0.57 ± 0.22, p < 0.01) and connective tissue growth factor (CTGF) (RV CTGF/GAPDH ratio; 0.49 ± 0.06 vs. 0.35 ± 0.17, p < 0.05). RV pro-apoptotic caspase-8 was increased in PAH compared to controls and was significantly reduced in both ventricles compared to PAH animals by carvedilol. Tissue effects were accompanied by improved biventricular systolic and diastolic performance and exercise treadmill distance (36 ± 30 vs. 80 ± 33 m, p < 0.05). In RV pressure-load, carvedilol improves biventricular fibrosis and function through abrogation of TGFβ1-CTGF signaling. KEY MESSAGE • RV afterload caused biventricular injury and dysfunction through TGFβ1-CTGF signaling. • Carvedilol reduced biventricular TGFβ1-CTGF signaling, fibrosis, and apoptosis. • Carvedilol improved cardiac output and biventricular function. • Improved fibrosis and hemodynamics occurred despite persistent RV afterload.

Abstract
Matrine, an alkaloid isolated from the traditional Chinese medicine Sophora flavescens AIT has exhibited a number of therapeutic effects on cardiovascular and liver diseases. The purpose of the present study was to investigate whether matrine has a protective effect on heart failure in rats. Coronary artery ligation was used to induce a heart failure (CHF) model in rats. Four weeks following the procedure, the rats were treated with different doses of matrine for one month. Histopathological examination demonstrated that matrine treatment alleviated myocardial hypertrophy and cardiac fibrosis in failing hearts. Furthermore, matrine administration also inhibited the increase of plasma aspartate amino transferase, creatine phosphokinase and lactate dehydrogenase levels in CHF rats. The rats with heart failure exhibited a significant reduction in ejection fraction and fractional shortening, as well as an increase in the left ventricular end systolic dimension, and matrine attenuated this decline in heart function. Further investigation demonstrated that matrine treatment also inhibited the upregulation of Bax and increase in the Bcl‑2 expression in the failing hearts. Furthermore, the upregulation of β3-adrenoreceptor (AR) and endothelial nitric oxide synthase proteins following heart failure were also attenuated by matrine. In conclusion, matrine had a preventive role in heart failure in rats at least in part by inhibiting myocardial apoptosis and the β3-AR pathway.

Abstract
OBJECTIVES This study was designed to investigate the cardioprotective effects of matrine on regulation of endothelial nitric oxide synthase (eNOS) and asymmetric dimethylarginine (ADMA) in isoproterenol-induced acute myocardial ischaemic rats. METHODS Male Sprague-Dawley rats were pretreated with matrine (200, 100 and 50 mg/kg) orally for 10 days. Acute myocardial injury was induced in rats by subcutaneous injection of isoproterenol. Serum and haemodynamic parameters, histopathological variables and expression of protein levels were analysed. KEY FINDINGS Oral administration of matrine (200, 100 and 50 mg/kg) significantly attenuated isoproterenol-induced cardiac necrosis and left ventricular dysfunction. Matrine treatment restored impaired ventricular Akt and eNOS protein expression with concomitant increased phosphorylation of Akt (Ser473) and eNOS (Ser1177), and also restored glycogen synthase kinase 3β activity, as indicated by increased phosphorylation at Ser 9. Moreover, treatment with matrine had no effect on the isoproterenol-induced elevated protein arginine methyltransferase 1 protein expression, but could significantly normalize the reduced dimethylarginine dimethylaminohydrolase 2 expression and attenuate the increased serum level of ADMA. The expression of catechol-o-methyltransferase and monoamine oxidase did not differ among all groups (all P > 0.05). CONCLUSIONS Our results suggested that matrine protects against isoproterenol-induced myocardial ischaemia via eNOS and ADMA pathway.

Abstract
OBJECTIVES This study was designed to explore the effect and mechanism of matrine, an active component of Chinese traditional medicine, on isoproterenol-induced acute cardiotoxicity in rats. METHODS Acute myocardial injury was induced in rats by daily subcutaneous injection of isoproterenol (85 mg/kg) for two days. Haemodynamic and biochemical parameters were measured and histopathological examination was performed. KEY FINDINGS Chronic oral administration of matrine (50, 100 or 200 mg/kg per day for 10 days) significantly reduced the release of lactic dehydrogenase, glutamic oxaloacetic transaminase and creatine kinase after isoproterenol-induced myocardial ischaemic injury, improved the left ventricular (LV) dysfunction, including increased LV systolic pressure (LVSP), maximum rate of developed LV pressure (LV dP/dt(max)) and minimum rate of developed LV pressure (LV dP/dt(min)), increased the activity of superoxide dismutase, catalase and glutathione peroxidase, and also decreased the content of the lipid peroxidation product malondialdehyde in plasma and myocardial tissues in rats. Acute oral administration of matrine at a dose of 100 or 200 mg/kg for two days also had a cardioprotective effect on this rat model. The protective role of matrine on isoproterenol-induced myocardial damage was further confirmed by histopathological examination. There were no significant changes in heart rate and blood pressure in all experimental groups. CONCLUSIONS Our results suggest that matrine has a significant cardioprotection against isoproterenol-induced cardiotoxicity through its antioxidant property.

Abstract
OBJECTIVE Patients with hypertensive left-ventricular hypertrophy (LVH) have lower coronary flow reserve (CFR). Whether carvedilol can improve CFR of patients with hypertensive LVH is unknown. We aimed to investigate the effects of carvedilol on CFR in patients with hypertensive LVH. METHODS Sixty-three patients were randomly divided into two groups for treatment with carvedilol or metoprolol. The peak diastolic coronary flow velocity in the left anterior descending coronary artery at rest and at maximal vasodilation with dipyridamole infusion was recorded by transesophageal echocardiography (TEE), then CFR was calculated at baseline and at the end of 6 months of therapy. Left-ventricular mass index (LVMI) was calculated by 2-D echocardiography. Endothelium-dependent and -independent reactivity of the brachial artery was measured. Levels of plasma endothelin-1 (ET1), nitric oxide (NO) and other metabolites were monitored and analyzed before and after 6-month therapy. RESULTS Both blood pressure and heart rate decreased significantly in the two treatment groups after therapy (p<0.05). With carvedilol treatment, LVMI was lower (p<0.05), endothelium function of the brachial artery was higher (p<0.05), and peak diastolic coronary flow velocity at rest and at maximal vasodilation after dipyridamole infusion was significantly higher (p<0.05) than with metoprolol treatment, which led to a significantly higher CFR (p<0.05). Changes in CFR and LVMI with carvedilol treatment were inversely correlated (R(2)=0.474, p=0.036). With carvedilol treatment, plasma level of ET-1 was lower, but that of NO was significantly higher than with metoprolol treatment (both p<0.05). CONCLUSIONS The CFR of patients with hypertensive LVH but not coronary artery disease could increase with 6-month carvedilol therapy.

Abstract
The present study was designed to assess the effect of matrine, an active component of Chinese traditional medicine, on angiotensin II (Ang II)-induced hyperplastic growth of cardiac fibroblasts in vitro. Cardiac fibroblasts were prepared from hearts of neonatal Kunming mice by collagenase disruption. Cultured cardiac fibroblasts were either not treated, treated with 0.1 microM Ang II, or matrine (2.0 approximately 4.0 mM) plus Ang II for 12-72 hr. Cell morphology was monitored under an inverted phase contrast microscope. Number of cells was counted with a haemocytometer. Cell apoptosis was determined by propidium iodide/Hoechst 33342 staining and flow cytometry. The cleaved caspase-3 fragment expression, anti-apoptotic Bcl-2 and pro-apoptotic Bax protein expressions were also studied. The results show that Ang II stimulation resulted in hyperplastic growth of cardiac fibroblasts. Matrine significantly, dose and time dependently inhibited Ang II-induced cell proliferation. Matrine addition to the culture medium led to most cells being arrested in the G1 phase of the cell cycle, the fraction of cells in S phase was markedly decreased compared to control and Ang II alone groups. Cell apoptosis in matrine treatment group was markedly increased, accompanied by down-regulation in Bcl-2/Bax ratio and up-regulation in cleaved caspase-3 activity. These results suggest that matrine can induce apoptosis and thereby inhibit Ang II-induced hyperplasic growth of cardiac fibroblasts. The regulations of matrine on Bcl-2/Bax expression and caspase-3 activation may be the pro-apoptotic mechanisms involved.
