Objective

To observe the effects of Kangxian Yixin Decoction(抗纤益心方,KYD)on myocardial mitochondrial ridge and its structural proteins mitochondrial inner membrane ridge structure protein 10(Mic10),mitochondrial inner membrane ridge structure protein 60(Mic60)and mitochondrial inner membrane ridge structure protein 19(Mic19)in mice with dilatedcardiomyopathy(DCM),and explore the mechanism of protecting DCM mitochondrial ridge structure and improving mitochondrial energy metabolism.

Methods

According to random number table method,40 cTnTR141W transgenic DCM mice were divided into model group,KYD low-dose group,KYD medium-dose group,KYD high-dose group and captopril group,with 8 mice in each group,and 8 C57BL/6J mice in normal group.Left ventricular end-systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD),ejection fraction(EF)and fraction shorting(FS)were detected by ultrasonography.Myocardial pathological morphology was observed by HE staining,and mitochondrial ultrastructure was observed by electron microscopy.Enzyme-linked immunosorbent assay(ELISA)was used to detect the contents of NT-proBNP and adenosine triphosphate(ATP)in serum of mice.The mRNA and protein expressions of Mic10,Mic60 and Mic19 were detected by Real-time PCR and Western blotting,respectively.

Result

Compared with those in the normal group,in the model group,the levels of LVESD and LVEDD were increased,the levels of FS and EF were decreased(P<0.05),myocardial pathological injury was observed,apoptotic number was increased(P<0.01),NT-proBNP content was increased,ATP content was decreased(P<0.01),mitochondrial ridge structure was damaged and disordered.The mRNA and protein expressions of mitochondrial ridge structure proteins Mic10,Mic60 and Mic19 were decreased(P<0.01). Compared with those in the model group,in the KYD group,the levels of LVESD and LVEDD were decreased,the levels of FS and EF were increased(P<0.05),the myocardial injury was alleviated,the NT-proBNP content was decreased(P<0.01),the apoptosis was decreased,the ATP content was increased(P<0.05),the mitochondrial ridge damage and arrangement disorder were improved and the mRNA and protein expressions of mitochondrial ridge structure proteins Mic10,Mic60 and Mic19 were increased(P<0.01).

Conclusion

KYD can improve DCM mice mitochondrial ridge arrangement disorder,alleviate myocardial cell apoptosis,and improve cardiac function,which may be related to increasing the expression of mitochondrial ridge structural proteins Mic10,Mic60 and Mic19 and improving mitochondrial energy metabolism.

目的

观察抗纤益心方对扩张型心肌病(Dilated cardiomyopathy,DCM)小鼠心肌线粒体内膜嵴重构及其线粒体内膜嵴结构蛋白10(Mitochondrial inner membrane ridge structure protein 10,Mic10)、线粒体内膜嵴结构蛋白60(Mitochondrial inner membrane ridge structure protein 60,Mic60)、线粒体内膜嵴结构蛋白19(Mitochondrial inner membrane ridge structure protein 19,Mic19)的影响,探讨其保护DCM线粒体嵴结构,改善线粒体能量代谢的作用机制。

方法

按照随机数字表法将40只cTnTR141W转基因DCM小鼠分为模型组、抗纤益心方低剂量组、抗纤益心方中剂量组、抗纤益心方高剂量组、卡托普利组,每组8只,另设C57BL/6J小鼠为正常组8只,各组小鼠灌胃8周后,小动物超声仪检测左心室收缩末期内径(Left ventricular end-systolic diameter,LVESD)、左心室舒张末期内径(Left ventricular end-diastolic diameter,LVEDD)、射血分数(Ejection fraction,EF)、缩短率(Fraction shorting,FS),HE染色观察心肌病理形态,电镜观察线粒体超微结构,酶联免疫吸附测定法(Enzyme linked immunosorbent assay,ELISA)检测小鼠血清氨基端前脑钠素(N-terminal brain natriuretic peptide precursor,NT-proBNP)、三磷酸腺苷(Adenosine triphosphate,ATP)含量,TUNEL法检测心肌组织凋亡情况,实时荧光定量聚合酶链式反应(Real-time PCR,RT-PCR)和蛋白免疫印迹法(Western Blotting,WB)分别检测心肌线粒体嵴Mic10、Mic60、Mic19 mRNA和蛋白表达。

结果

与正常组比较,模型组小鼠NT-proBNP含量增加(P<0.01),LVESD和LVEDD升高、FS和EF降低(P<0.05),心肌病理损伤,细胞凋亡数增加(P<0.01),ATP含量降低(P<0.01),线粒体嵴结构受损、排列紊乱,线粒体嵴结构蛋白Mic10、Mic60、Mic19 mRNA和蛋白表达均降低(P<0.01);与模型组比较,抗纤益心方组NT-proBNP含量降低(P<0.05),LVESD和LVEDD降低、FS和EF增加(P<0.05),心肌损伤减轻,细胞凋亡减少,ATP含量增加(P<0.05),线粒体嵴受损及排列紊乱改善,线粒体嵴Mic10、Mic60、Mic19 mRNA和蛋白表达均增加(P<0.01)。

结论

抗纤益心方能够改善DCM小鼠线粒体嵴排列紊乱,减轻心肌细胞凋亡,提高心脏功能,其作用机制可能与增加线粒体嵴结构蛋白Mic10、Mic60、Mic19表达,改善线粒体能量代谢有关。

方法

按照随机数字表法将40只cTnTR141W转基因DCM小鼠分为模型组、抗纤益心方低剂量组、抗纤益心方中剂量组、抗纤益心方高剂量组、卡托普利组,每组8只,另设C57BL/6J小鼠为正常组8只,各组小鼠灌胃8周后,小动物超声仪检测左心室收缩末期内径(Left ventricular end-systolic diameter,LVESD)、左心室舒张末期内径(Left ventricular end-diastolic diameter,LVEDD)、射血分数(Ejection fraction,EF)、缩短率(Fraction shorting,FS),HE染色观察心肌病理形态,电镜观察线粒体超微结构,酶联免疫吸附测定法(Enzyme linked immunosorbent assay,ELISA)检测小鼠血清氨基端前脑钠素(N-terminal brain natriuretic peptide precursor,NT-proBNP)、三磷酸腺苷(Adenosine triphosphate,ATP)含量,TUNEL法检测心肌组织凋亡情况,实时荧光定量聚合酶链式反应(Real-time PCR,RT-PCR)和蛋白免疫印迹法(Western Blotting,WB)分别检测心肌线粒体嵴Mic10、Mic60、Mic19 mRNA和蛋白表达。

结果

与正常组比较,模型组小鼠NT-proBNP含量增加(P<0.01),LVESD和LVEDD升高、FS和EF降低(P<0.05),心肌病理损伤,细胞凋亡数增加(P<0.01),ATP含量降低(P<0.01),线粒体嵴结构受损、排列紊乱,线粒体嵴结构蛋白Mic10、Mic60、Mic19 mRNA和蛋白表达均降低(P<0.01);与模型组比较,抗纤益心方组NT-proBNP含量降低(P<0.05),LVESD和LVEDD降低、FS和EF增加(P<0.05),心肌损伤减轻,细胞凋亡减少,ATP含量增加(P<0.05),线粒体嵴受损及排列紊乱改善,线粒体嵴Mic10、Mic60、Mic19 mRNA和蛋白表达均增加(P<0.01)。

结论

抗纤益心方能够改善DCM小鼠线粒体嵴排列紊乱,减轻心肌细胞凋亡,提高心脏功能,其作用机制可能与增加线粒体嵴结构蛋白Mic10、Mic60、Mic19表达,改善线粒体能量代谢有关。

扩张型心肌病(Dilated cardiomyopathy,DCM)是引起心力衰竭的重要病因,主要特征心肌收缩功能障碍、心脏扩大,病情呈进行性加重,其病因及病理机制尚不完全明确[1-2],目前缺乏有效的治疗手段[3],预后较差。研究表明,线粒体能量代谢在DCM发展过程中具有重要作用[4-5]。线粒体是含有双层膜结构的动态细胞器,其内膜深入基质处突起形成线粒体嵴是线粒体氧化磷酸化的关键位点,亦是产生ATP供能基地[6]。线粒体嵴形态及重构调控细胞多种功能[7],DCM发生时,细胞内活性氧增加,嵴连接被重构以促进凋亡膜间隙蛋白的释放,ATP产能不足,线粒体嵴损伤,嵴形态重构发生,能量代谢障碍,引发心肌重构以及细胞凋亡[8],促使DCM发展。Mic10、Mic60、Mic19为线粒体嵴结构关键蛋白,在维持线粒体嵴结构形成和功能中发挥重要作用[9]。因此,调控线粒体嵴结构蛋白与功能可能成为防治DCM的潜在作用靶点。
中医学认为DCM可归属“心胀”“心衰”“喘证”等范畴,为本虚标实证,本团队王振涛教授长期致力于DCM研究,认为宗气下陷为DCM核心病机,标实责之瘀血、水湿等。“益气升陷”为针对DCM“宗气下陷”的病机所立治法,根据治法拟抗纤益心方,具有益气升陷、活血化瘀功效,临床取得较好效果[10-11],前期研究发现,抗纤益心方能通过减轻细胞凋亡、抑制心肌重构、提高心功能,从而延缓DCM进程,且对线粒体结构和功能及能量代谢具有一定的改善作用[12]。然而,抗纤益心方调节线粒体结构与功能的潜在机制尚未阐明。本研究通过建立DCM小鼠模型,以观察抗纤益心方对DCM小鼠心功能、线粒体超微结构及线粒体嵴结构蛋白Mic10、Mic60、Mic19表达的影响及作用机制,为抗纤益心方治疗DCM提供科学的实验依据。

扩张型心肌病属于临床常见心肌病之一,是导致心力衰竭的重要原因。我国最近一项报道显示其52个月病死率为42.64%[2],其发病率有逐渐上升的趋势。能量代谢障碍是DCM发生发展主要病理过程,而线粒体结构和功能损伤是引起能量代谢障碍,导致DCM的重要因素[13]。临床上通过应用改善心肌能量代谢药物辅酶Q10、磷酸肌酸钠、曲美他嗪等可以起到缓解作用,但效果有限[14-15],因此开发改善线粒体心肌能量代谢药物尤为迫切需要。
中医药治疗DCM具有一定优势,我们团队王振涛教授长期从事DCM研究,根据四十余年临床实践,提出宗气下陷为DCM核心病机,瘀血贯穿于本病始终,故临床治疗以益气升陷活血法为基本治法,根据治法拟定抗纤益心方治疗DCM,疗效获得患者满意。方中黄芪为君药,具有益气升陷功效,发挥直补宗气下陷,直达病所的作用;宗气下陷与脾胃之气密切相关,故臣药用红参补脾胃之气,白术、茯苓健运脾胃,以恢复脾胃功能;益母草、丹参、泽兰活血化瘀利水以解决标实之症;麦冬具有滋心阴而不助湿,为佐药,且可制约补气药的燥性;升麻具有升陷功效,作为使药升提引经作用。前期研究表明,抗纤益心方能够改善DCM小鼠线粒体结构异常,提高线粒体功能作用[12],为进一步探讨抗纤益心方调节线粒体的作用机制提供实验依据。
本实验利用cTnTR141W转基因小鼠成功建立DCM模型,探讨抗纤益心方对调节线粒体嵴作用机制。研究表明,不同因素导致DCM出现心肌病理性损伤,活性氧增加[16],细胞凋亡增加,线粒体嵴破裂、排列紊乱,ATP产生减少,线粒体功能异常,能量代谢障碍[17-18],从而导致DCM心力衰竭。在这一过程中,线粒体嵴结构受损与重构是导致线粒体功能下降加重DCM心力衰竭的重要病理机制。Mic10、Mic60、Mic19是线粒体嵴结构关键蛋白,三者分布于线粒体内膜[19-20],在维持线粒体的正常功能及嵴形态上具有重要作用[21-22]。研究表明,线粒体对不同生理条件的适应高度依赖于线粒体超微结构的调节,特别是在线粒体嵴区室水平上[23],嵴数量和形状的变化决定了线粒体呼吸能力和细胞活力[24-25]。在DCM演变过程中,心肌损伤,线粒体结构与功能出现失调,线粒体嵴结构蛋白Mic10、Mic60、Mic19丢失,线粒体嵴与内膜直接物理接触丧失[26],线粒体内膜边界堆积,嵴受到不可修复的损害,线粒体无法维持其正常的生理功能[27],细胞内重要的生命活动都会受到不同程度的抑制[28-29]。综合以上因素,通过调节线粒体嵴结构蛋白表达,是维持线粒体功能及嵴形态的正常、改善心肌能量代谢、提高心脏功能的潜在作用靶点。研究报道,线粒体嵴结构蛋白Mic10或Mic60或Mic19缺失,线粒体嵴与内膜的连接中断,嵴形态改变,线粒体结构与功能损伤。而通过调节Mic10、Mic60或Mic19表达,可保护线粒体结构和功能,改善能量代谢[30]。
本实验研究显示,模型组NT-proBNP水平明显增加,心脏超声显示心脏FS和EF降低、心功能下降,心肌组织病理心肌出现间质水肿、心肌纤维排列紊乱,纤维胶原沉积,电镜下显示线粒体结构损伤、线粒体双层膜模糊或消失、线粒体嵴数量减少、线粒体嵴破裂、排列紊乱,TUNEL结果显示细胞凋亡率增多,ATP含量降低,同时线粒体嵴结构蛋白Mic10、Mic60、Mic19的mRNA和蛋白表达均明显下调,表明DCM心功能下降,心肌纤维排列紊乱,心肌细胞凋亡增加可能与线粒体嵴相关。通过与模型组比较,抗纤益心方高、中、低剂量干预后,DCM小鼠NT-proBNP水平明显降低,心脏FS和EF增加,心肌组织病理心肌出现间质水肿和纤维胶原沉积减少,心肌损伤减轻,电镜下线粒体形态部分恢复正常、有少量的受损线粒体嵴、嵴排列较整齐,细胞凋亡程度减轻,且线粒体嵴结构蛋白Mic10、Mic60、Mic19的mRNA和蛋白表达明显增加,提示抗纤益心方可能通过上调线粒体嵴结构蛋白表达,保护线粒体结构与功能,改善能量代谢,提高心脏功能。
综上所述,抗纤益心方能够调节DCM心肌线粒体嵴结构蛋白Mic10、Mic60、Mic19表达,促进ATP产能,改善线粒体嵴形态与重构,减少细胞凋亡,提高心脏功能,从而改善DCM。此研究为从调节线粒体能量代谢角度改善DCM药物开发提供一定参考。但DCM发病机制复杂,本研究只表明了抗纤益心方改善DCM机制可能与调节线粒体嵴结构蛋白Mic10、Mic60、Mic19表达,改善线粒体嵴形态与重构及能量代谢有关。未能全面阐述治疗DCM机制,今后仍需进一步研究,以期为中医药改善线粒体嵴结构与功能,治疗DCM提供更加完善的科学实验依据。
