  • 文章类型: Journal Article
    越来越多的证据表明,摄入反式脂肪酸(TFA)会增加许多疾病的风险,比如心血管疾病。最近,我们小组发现,某些天然硫化合物(异硫氰酸烯丙酯[AITC]和二烯丙基二硫化物[DADS])在热处理过程中促进脂肪酸酯的顺式至反式异构化。然而,关于脂肪酸异构化的信息很少。在这项研究中,我们研究了在AITC和DADS存在下,氧气和α-生育酚(抗氧化剂)对油酸(18:1)甲酯(OA-ME)异构化的影响。此外,评估了同时使用AITC和DADS的效果。我们的结果表明,氧气增强了AITC诱导的反式异构化,并且发现DADS在加热期间促进反式异构化但抑制AITC诱导的反式异构化。α-生育酚抑制了AITC和DADS诱导的反式异构化。这些结果表明,可以通过设计烹饪方法和一起使用的食品成分来控制由硫化合物诱导的脂肪酸的反式异构化。
    Growing evidence indicates that the intake of trans fatty acids (TFAs) increases the risk of numerous diseases, such as cardiovascular diseases. Recently, our group found that certain natural sulfur compounds (allyl isothiocyanate [AITC] and diallyl disulfide [DADS]) promote cis to trans isomerization of fatty acid esters during heat treatment. However, little information is available on the fatty acid isomerization with them. In this study, we investigated the effects of oxygen and α-tocopherol (antioxidant) on isomerization of oleic acid (18:1) methyl ester (OA-ME) in the presence of AITC and DADS. Furthermore, the effect of the simultaneous use of AITC and DADS was evaluated. Our results indicate that oxygen enhances the AITC-induced trans isomerization, and DADS was found to promote trans isomerization but inhibit AITC-induced trans isomerization during heating. Both AITC- and DADS-induced trans isomerization were inhibited by α-tocopherol. These results indicate that the trans isomerization of fatty acids induced by sulfur compounds can be controlled by devising a cooking process and the food ingredients used together.

    芥菜(BrassicajunceaL.)的生物增感特性得到了探索,来自其次级代谢产物,特别是异硫氰酸烯丙酯(AITC),在芥子苷等芥子油苷的酶分解过程中产生。本研究考察了丽苏市开发的八个芥菜品种,韩国,关注它们的遗传特征,AITC浓度和芥子油苷的腈形成率。结果表明,化感作用,很大程度上取决于AITC浓度和酶活性,因品种而异。Sinigrin和AITC分别占79%和36%,分别,芥子油苷及其水解产物。品种“Nuttongii”显示出抑制杂草的显着潜力,在27.47±6.46µmoleg-1处表现出最高的AITC浓度。这些结果突显了根据芥子油苷的概况和水解产物的产量选择芥子菜品种进行生物熏蒸的重要性。该研究还确定了对AITC和腈形成的显着遗传影响,这表明表硫特异性蛋白调节可以增强化感作用和其他有益作用。总的来说,这项研究强调了芥末作为一种可持续的,环保替代传统除草剂。
    Leaf mustard (Brassica juncea L.) is explored for its biofumigant properties, derived from its secondary metabolites, particularly allyl isothiocyanate (AITC), produced during the enzymatic breakdown of glucosinolates like sinigrin. The research examines eight leaf mustard cultivars developed in Yeosu city, South Korea, focusing on their genetic characteristics, AITC concentration and nitriles formation rates from glucosinolates. Results indicate that the allelopathic effects, largely dependent on AITC concentration and enzymatic activity, vary across cultivar. Sinigrin and AITC constitute 79% and 36%, respectively, of glucosinolate and its hydrolysis products. The cultivar \'Nuttongii\' demonstrates significant potential for inhibiting weeds, exhibiting the highest AITC concentration at 27.47 ± 6.46 µmole g-1 These outcomes highlight the importance of selecting mustard cultivars for biofumigation based on their glucosinolate profiles and hydrolysis product yields. The study also identifies a significant genetic influence on AITC and nitrile formation, suggesting that epithiospecifier protein modulation could enhance both allelopathic and other beneficial effects. Collectively, the research underscores the promise of mustard as a sustainable, environmentally friendly alternative to traditional herbicides.

    奥氮平,广泛处方的非典型抗精神病药,通过制造大量严重的代谢和心血管不良反应,最终降低预期寿命和患者依从性,对患者的健康构成巨大风险。其异质受体结合谱使得难以指出相关副作用的具体原因或治疗。越来越多的证据表明,瞬时受体电位(TRP)通道亚家族Ankyrin1(TRPA1)在2型糖尿病和肥胖的发病机制中具有重要作用。在这样的背景下,我们旨在研究使用异硫氰酸烯丙酯(AITC)和HC-030031(TRPA1激动剂和拮抗剂,分别)。结果发现,经过6周的治疗,AITC预防奥氮平诱导的体重和肥胖改变;血清,和肝脏炎症标志物;糖脂代谢;和下丘脑食欲调节,营养传感,炎症和TRPA1通道信号调节基因。此外,在存在HC-030031(TRPA1拮抗剂)的情况下,这些效应中的一些不存在,表明TRPA1激动作用在减轻奥氮平诱导的代谢改变方面具有保护作用.需要补充深入研究来研究TRPA1通道对奥氮平诱导的代谢改变的其他方面的影响。
    Olanzapine, a widely prescribed atypical antipsychotic, poses a great risk to the patient\'s health by fabricating a plethora of severe metabolic and cardiovascular adverse effects eventually reducing life expectancy and patient compliance. Its heterogenous receptor binding profile has made it difficult to point out a specific cause or treatment for the related side effects. Growing body of evidence suggest that transient receptor potential (TRP) channel subfamily Ankyrin 1 (TRPA1) has pivotal role in pathogenesis of type 2 diabetes and obesity. With this background, we aimed to investigate the role of pharmacological manipulations of TRPA1 channels in antipsychotic (olanzapine)-induced metabolic alterations in female mice using allyl isothiocyanate (AITC) and HC-030031 (TRPA1 agonist and antagonist, respectively). It was found that after 6 weeks of treatment, AITC prevented olanzapine-induced alterations in body weight and adiposity; serum, and liver inflammatory markers; glucose and lipid metabolism; and hypothalamic appetite regulation, nutrient sensing, inflammatory and TRPA1 channel signaling regulating genes. Furthermore, several of these effects were absent in the presence of HC-030031 (TRPA1 antagonist) indicating protective role of TRPA1 agonism in attenuating olanzapine-induced metabolic alterations. Supplementary in-depth studies are required to study TRPA1 channel effect on other aspects of olanzapine-induced metabolic alterations.

    癌症生长是由参与细胞增殖的遗传和表观遗传修饰引发的分子机制。分化,凋亡,和衰老途径。化学预防是导致阻断的癌症治疗的重要策略,倒车,或者阻碍肿瘤发生的多步骤过程,包括其重要的形态发生里程碑的阻塞。正常,肿瘤前,瘤形成,和转移。由于许多原因,与合成药物相比,天然存在的植物化学物质变得越来越受欢迎。包括安全,生物利用度,功效,和容易的可用性。异硫氰酸烯丙酯(AITC)是十字花科所有植物中存在的天然化合物,比如抱子甘蓝,花椰菜,芥末,卷心菜,卷心菜羽衣甘蓝,辣根,还有芥末.几十年来进行的体外和体内研究表明,AITC抑制肿瘤发生,没有任何毒性和不良副作用。AITC的生物利用度非常高,据报道,近90%的口服AITC被吸收。AITC表现出多种药理学性质,其中其抗癌活性对于癌症治疗是最显著的。其抗癌活性是通过选择性调节与氧化应激相关的多种细胞信号通路发挥的,炎症,细胞增殖,细胞周期停滞,凋亡,血管生成,入侵,和转移。这篇综述强调了与(i)抑制致癌活化和诱导抗氧化剂相关的AITC抗癌作用有关的分子靶标的最新知识,(ii)抑制促炎和细胞增殖信号,(iii)诱导细胞周期停滞和凋亡,和(iv)抑制与转移相关的血管生成和侵袭性信号。
    Cancer growth is a molecular mechanism initiated by genetic and epigenetic modifications that are involved in cell proliferation, differentiation, apoptosis, and senescence pathways. Chemoprevention is an important strategy for cancer treatment that leads to blocking, reversing, or impeding the multistep process of tumorigenesis, including the blockage of its vital morphogenetic milestones viz. normal, preneoplasia, neoplasia, and metastasis. Naturally occurring phytochemicals are becoming ever more popular compared to synthetic drugs for many reasons, including safety, bioavailability, efficacy, and easy availability. Allyl isothiocyanate (AITC) is a natural compound present in all plants of the Cruciferae family, such as Brussels sprouts, cauliflower, mustard, cabbage, kale, horseradish, and wasabi. In vitro and in vivo studies carried out over the decades have revealed that AITC inhibits tumorigenesis without any toxicity and undesirable side effects. The bioavailability of AITC is exceedingly high, as it was reported that nearly 90% of orally administered AITC is absorbed. AITC exhibits multiple pharmacological properties among which its anticancer activity is the most significant for cancer treatment. Its anticancer activity is exerted via selective modulation of multiple cell signaling pathways related to oxidative stress, inflammation, cell proliferation, cell cycle arrest, apoptosis, angiogenesis, invasion, and metastasis. This review highlights the current knowledge on molecular targets that are involved in the anticancer effect of AITC associated with (i) inhibition of carcinogenic activation and induction of antioxidants, (ii) suppression of pro-inflammatory and cell proliferative signals, (iii) induction of cell cycle arrest and apoptosis, and (iv) inhibition of angiogenic and invasive signals related to metastasis.

    异硫氰酸烯丙酯(AITC)在十字花科蔬菜中含量丰富,在体外和体内许多类型的人类癌细胞中都具有药理活性,包括抗癌活性。目前,没有可用的信息显示AITC影响人胃癌细胞中DNA损伤和修复相关蛋白的表达。因此,在目前的研究中,我们在体外研究了AITC诱导的AGS和SNU-1细胞对人胃癌的细胞毒性作用,无论是否通过诱导DNA损伤和影响DNA损伤和修复相关的potetins表达。通过流式细胞仪和相差显微镜测定细胞活力和形态变化,分别,结果表明,AITC诱导AGS和SNU-1细胞的细胞形态变化,并呈剂量依赖性地减少了总存活细胞。AITC以剂量依赖性的方式诱导DNA凝聚和损伤,基于细胞核被4'染色,6-二氨基-2-苯基吲哚存在于AGS和SNU-1细胞中。通过蛋白质印迹法测量AGS和SNU-1细胞中DNA损伤和修复相关蛋白的表达。结果表明AITC降低了核因子红系2相关因子2(NRF2),血红素加氧酶-1(HO-1),谷胱甘肽,和过氧化氢酶,但增加超氧化物歧化酶(SOD(Cu/Zn)),和AGS细胞中的一氧化氮合酶(iNOS),然而,在SNU-1细胞中是增加的HO-1。AITC增加DNA依赖性蛋白激酶(DNA-PK),γH2A组蛋白家族成员X在Ser139(γH2AXpSer139)上的磷酸化,AGS细胞中的热休克蛋白90(HSP90)。AITC增加了DNA-PK,DNA损伤检查点蛋白1(MDC1)的介质,γH2AXpSer139,拓扑异构酶IIα(TOPIIα),拓扑异构酶IIβ(TOPIIβ),SNU-1细胞中的HSP90和热休克蛋白70(HSP70)。AITC增加p53,p53pSer15,和p21,但降低了小鼠双分钟2(MDM2)pSer166和O6-甲基鸟嘌呤-DNA甲基转移酶(MGMT)在AGS细胞;除了共济失调毛细血管扩张症和Rad3相关蛋白(ATR)pSer428外,它具有与AITC相似的作用,检查点激酶1(CHK1),和SNU-1细胞中的检查点激酶2(CHK2)。显然,两种细胞对AITC的反应是不同的,尽管如此,所有这些观察结果表明,AITC可能通过诱导DNA损伤来抑制胃癌细胞的生长。
    Allyl isothiocyanate (AITC) is abundant in cruciferous vegetables and it present pharmacological activity including anticancer activity in many types of human cancer cells in vitro and in vivo. Currently, no available information to show AITC affecting DNA damage and repair-associated protein expression in human gastric cancer cells. Therefore, in the present studies, we investigated AITC-induced cytotoxic effects on human gastric cancer in AGS and SNU-1 cells whether or not via the induction of DNA damage and affected DNA damage and repair associated poteins expressions in vitro. Cell viability and morphological changes were assayed by flow cytometer and phase contrast microscopy, respectively, the results indicated AITC induced cell morphological changes and decreased total viable cells in AGS and SNU-1 cells in a dose-dependently. AITC induced DNA condensation and damage in a dose-dependently which based on the cell nuclei was stained by 4\', 6-diamidino-2-phenylindole present in AGS and SNU-1 cells. DNA damage and repair associated proteins expression in AGS and SNU-1 cells were measured by Western blotting. The results indicated AITC decreased nuclear factor erythroid 2-related factor 2 (NRF2), heme oxygenase-1 (HO-1), glutathione, and catalase, but increased superoxide dismutase (SOD (Cu/Zn)), and nitric oxide synthase (iNOS) in AGS cells, however, in SNU-1 cells are increased HO-1. AITC increased DNA-dependent protein kinase (DNA-PK), phosphorylation of gamma H2A histone family member X on Ser139 (γH2AXpSer139 ), and heat shock protein 90 (HSP90) in AGS cells. AITC increased DNA-PK, mediator of DNA damage checkpoint protein 1 (MDC1), γH2AXpSer139 , topoisomerase II alpha (TOPIIα), topoisomerase II beta (TOPIIβ), HSP90, and heat shock protein 70 (HSP70) in SNU-1 cells. AITC increased p53, p53pSer15 , and p21 but decreased murine double minute 2 (MDM2)pSer166 and O6 -methylguanine-DNA methyltransferase (MGMT) in AGS cells; however, it has a similar effect of AITC except increased ataxia telangiectasia and Rad3 -related protein (ATR)pSer428 , checkpoint kinase 1 (CHK1), and checkpoint kinase 2 (CHK2) in SNU-1 cells. Apparently, both cell responses to AITC are different, nonetheless, all of these observations suggest that AITC inhibits the growth of gastric cancer cells may through induction off DNA damage in vitro.

    细胞周期蛋白基因的表达失调可导致癌细胞的不受控制的增殖。含组蛋白去甲基酶Jumonji-C结构域的蛋白5(KDM8,JMJD5)和细胞周期蛋白A1(CCNA1)在细胞周期进程中是关键的。增强癌症治疗的有希望的候选者是异硫氰酸烯丙酯(AITC),一种天然的饮食化疗和表观遗传调节剂。本研究旨在探讨AITC对KDM8/CCNA1轴的影响,以阐明其在口腔鳞状细胞癌(OSCC)肿瘤发生中的作用。使用组织微阵列(TMA)免疫组织化学(IHC)测定评估KDM8和CCNA1的表达。进行了OSCC细胞系的体外实验以及患者来源的肿瘤异种移植(PDTX)和SAS皮下异种移植肿瘤模型的体内实验,以探讨AITC对其表达和细胞增殖的影响。结果显示OSCC患者样品中升高的KDM8和CCNA1水平。AITC在体外和体内对OSCC肿瘤生长均表现出抑制作用。此外,AITC下调KDM8和CCNA1表达,同时诱导口腔癌细胞中组蛋白H3K36me2表达。这些发现强调了AITC对口腔癌的显着抗癌特性,通过靶向KDM8/CCNA1轴破坏细胞周期,突出了其作为口腔癌治疗的治疗选择的潜力。
    The dysregulated expression of cyclin genes can lead to the uncontrolled proliferation of cancer cells. Histone demethylase Jumonji-C domain-containing protein 5 (KDM8, JMJD5) and cyclin A1 (CCNA1) are pivotal in cell cycle progression. A promising candidate for augmenting cancer treatment is Allyl isothiocyanate (AITC), a natural dietary chemotherapeutic and epigenetic modulator. This study aimed to investigate AITC\'s impact on the KDM8/CCNA1 axis to elucidate its role in oral squamous cell carcinoma (OSCC) tumorigenesis. The expression of KDM8 and CCNA1 was assessed using a tissue microarray (TMA) immunohistochemistry (IHC) assay. In vitro experiments with OSCC cell lines and in vivo experiments with patient-derived tumor xenograft (PDTX) and SAS subcutaneous xenograft tumor models were conducted to explore AITC\'s effects on their expression and cell proliferation. The results showed elevated KDM8 and CCNA1 levels in the OSCC patient samples. AITC exhibited inhibitory effects on OSCC tumor growth in vitro and in vivo. Additionally, AITC downregulated KDM8 and CCNA1 expression while inducing histone H3K36me2 expression in oral cancer cells. These findings underscore AITC\'s remarkable anticancer properties against oral cancer, highlighting its potential as a therapeutic option for oral cancer treatment by disrupting the cell cycle by targeting the KDM8/CCNA1 axis.

    我们使用结合单通道电生理和光学记录的方法研究了Daniorerio(斑马鱼)TRPA1通道,以同时评估单通道中的横向迁移率和通道门控。通过两种不同的化学配体激活TRPA1通道:异硫氰酸烯丙酯(AITC)和TRP开关B,导致质膜的通道横向迁移率大大降低。与胆固醇螯合剂甲基-β-环糊精(MβCD)一起孵育,防止由两种化学激动剂诱导的横向迁移率的降低。该结果强烈表明,TRPA1的开放构象可能通过促进通道插入质膜上富含胆固醇的结构域来调节通道的横向迁移率。
    We have studied Danio rerio (Zebrafish) TRPA1 channel using a method that combines single channel electrophysiological and optical recordings to evaluate lateral mobility and channel gating simultaneously in single channels. TRPA1 channel activation by two distinct chemical ligands: allyl isothiocyanate (AITC) and TRPswitch B, results in substantial reduction of channel lateral mobility at the plasma membrane. Incubation with the cholesterol sequestering agent methyl-β-cyclodextrin (MβCD), prevents the reduction on lateral mobility induced by the two chemical agonists. This results strongly suggest that the open conformation of TRPA1 modulates channel lateral mobility probably by facilitating the insertion of the channel into cholesterol-enriched domains at the plasma membrane.

    背景:异硫氰酸烯丙酯(AITC)是一种具有高挥发性的天然产品,可用作缓解土壤传播的植物病害的生物灭菌剂,以及需要连续种植的根结线虫(RKN)等问题。然而,很少有研究评估AITC熏蒸对药用植物的影响。
    结果:AITC显著降低了土壤中RKN的种群数量(p<0.0001),并在播种三七后6个月内表现出优异的RKN病害控制效果(p<0.0001)。经AITC土壤处理后,2年生三七的幼苗成活率约为1.7倍(p=0.1008)。16SrRNA测序表明,AITC处理影响了连续栽培(CC)土壤中的细菌丰富度而不是多样性。此外,AITC处理和未经处理的CC土壤之间具有统计差异的生物标志物表明,Pirellulales(order),Pirellulaceae(科),假单胞菌科(科),假单胞菌(属)在AITC治疗组中发挥重要作用。此外,使用BugBase工具预测的微生物组功能表型表明,AITC处理更有利于通过改变细菌群落结构来改善CC土壤。至关重要的是,我们的研究还表明,AITC土壤处理显著增加了土壤有机质(p=0.0055),总氮(p=0.0054),和有效钾(p=0.0373),这促进了成功的药用植物(黄精)的生存。
    结论:AITC是一种生态友好的土壤处理,影响前10种细菌的丰富度,但不影响多样性。它还可以为有用的农业土壤管理措施提供基础,以减轻土壤疾病。
    Allyl isothiocyanate (AITC) is a natural product with high volatility that is used as a biofumigant to alleviate soil-borne plant diseases, and problems such as root knot nematodes (RKNs) that necessitate continuous cropping. However, little research has assessed the effects of AITC fumigation on medicinal plants.
    AITC significantly reduced the population of RKNs in soil (p < 0.0001) and showed an excellent RKN disease control effect within 6 months after sowing Panax notoginseng (p < 0.0001). The seedling survival rate of 2-year-old P. notoginseng was approximately 1.7-fold higher after soil treatment with AITC (p = 0.1008). 16S rRNA sequencing indicated that the AITC treatment affected bacterial richness rather than diversity in consecutively cultivated (CC) soil. Furthermore, biomarkers with statistical differences between AITC-treated and untreated CC soil showed that Pirellulales (order), Pirellulaceae (family), Pseudomonadaceae (family), and Pseudomonas (genus) played important roles in the AITC-treated group. In addition, the microbiome functional phenotypes predicted using the BugBase tool suggested that AITC treatment is more conducive to improving CC soil through changes in the bacterial community structure. Crucially, our research also suggested that AITC soil treatment significantly increases soil organic matter (p = 0.0055), total nitrogen (p = 0.0054), and available potassium (p = 0.0373), which promotes the survival of a succeeding medicinal plant (Polygonatum kingianum).
    AITC is an ecologically friendly soil treatment that affects the top 10 bacterial richness but not diversity. It could also provide a basis for a useful agricultural soil management measure to alleviate soil sickness.

    心肌梗塞(MI)是缺血性心脏病的一种常见类型,影响全球数百万人。最近,纳米技术已经成为一个非常有前途的领域,具有广泛的应用。进行了当前的探索,以合成壳聚糖-海藻酸钠-聚乙二醇-Ally异硫氰酸酯纳米复合材料(CSP-AIso-NC),并评估其对大鼠异丙肾上腺素(ISO)诱导的MI的有益作用。制备了CSP-AIso-NC,并通过几种表征技术进行了表征。通过施用85mg/kg的ISO2天开始大鼠的MI,并用10和20mg/kg的CSP-AISo-NC治疗1个月。测量心脏重量和体重的变化。用超声心动图评估心脏功能标志物。脂质分布,Na+,K+,和Ca2+离子,心脏生物标志物,抗氧化剂参数,和炎性细胞因子使用相应的测定试剂盒进行评估。对心脏组织进行组织病理学研究。紫外光谱分析显示最大峰在208nm,这证实了CSP-AISo-NCs的形成。FT-IR分析揭示了不同官能团的存在,通过XRD分析证明了CSP-Also-NCs的结晶度。DLS分析表明CSP-Also-NC在146.50nm处的尺寸。CSP-AIso-NC治疗增加了MI大鼠的体重并降低了HW/BW比率。血脂状态降低,对MI大鼠给药的CSP-Aiso-NC中HDL升高。CSP-Aiso-NC减少了LVED,LVEDD,NT-proBNP和LVEF水平升高。氧化应激标志物降低,在MI大鼠中,通过CSP-Aiso-NC治疗增加了抗氧化剂。Na+和Ca+离子被还原,CSP-Also-NC增加了K+离子。白细胞介素-1β和肿瘤坏死因子-α也被耗尽,在MI大鼠的CSP-Aiso-NC中,Nrf-2得到了改善。组织学研究揭示了CSP-Aiso-NC的改善作用。总的来说,我们的结果显示,CSP-Aiso-NC对ISO诱导的MI大鼠有效.因此,它可能是MI治疗的一种有希望的治疗纳米药物。
    Myocardial infarction (MI) is a common type of ischemic heart disease that affects millions of people worldwide. In recent times, nanotechnology has become a very promising field with immense applications. The current exploration was conducted to synthesize the chitosan-sodium alginate-polyethylene glycol-Ally isothiocyanate nanocomposites (CSP-AIso-NCs) and evaluate their beneficial roles against the isoproterenol (ISO)-induced MI in rats. The CSP-AIso-NCs were prepared and characterized by several characterization techniques. The MI was initiated in the rats by the administration of 85 mg/kg of ISO for 2 days and treated with 10 and 20 mg/kg of CSP-AIso-NCs for 1 month. The changes in heart weight and bodyweight were measured. The cardiac function markers were assessed with echocardiography. The lipid profiles, Na+, K+, and Ca2+ ions, cardiac biomarkers, antioxidant parameters, and inflammatory cytokines were assessed using corresponding assay kits. The histopathological study was done on the heart tissues. The UV spectral analysis revealed the maximum peak at 208 nm, which confirms the formation of CSP-AIso-NCs. The FT-IR analysis revealed the occurrence of different functional groups, and the crystallinity of the CSP-AIso-NCs was proved by the XRD analysis. DLS analysis indicated the size of the CSP-AIso-NCs at 146.50 nm. The CSP-AIso-NCs treatment increased the bodyweight and decreased the HW/BW ratio in the MI rats. The status of lipids was reduced, and HDL was elevated in the CSP-AIso-NCs administered to MI rats. CSP-AIso-NCs decreased the LVEDs, LVEDd, and NT-proBNP and increased the LVEF level. The oxidative stress markers were decreased, and the antioxidants were increased by the CSP-AIso-NCs treatment in the MI rats. The Na+ and Ca+ ions were reduced, and the K+ ions were increased by the CSP-AIso-NCs. The interleukin-1β and tumor necrosis factor-α were also depleted, and Nrf-2 was improved in the CSP-AIso-NCs administered to MI rats. The histological study revealed the ameliorative effects of CSP-AIso-NCs. Overall, our outcomes revealed that the CSP-AIso-NCs are effective against the ISO-induced MI rats. Hence, it could be a hopeful therapeutic nanomedicine for MI treatment.
