Panax notogiseng saponin inhibits ischemia-induced apoptosis by activating PI3K/Akt signal pathway in cardiomyocytes

The panax notoginseng saponin(PNS) had been clinically used for the treatment of cardiovascular diseases and stroke in China.It had been demonstrated that PNS could protect cardiomyocytes from injury induced by ischemi- a,but the underlying molecular mechanisms of this protective effect were still unclear.This study was aimed to investigate the protective effect and molecular mechanisms of PNS on apoptosis in H9c2 cells in vitro and rat myocardial ischemia injury model in vivo.Annexin-V/PI assay shew that PNS could protect H9c2 cells from apoptosis induced by serum, glucose and oxygen deprivation(SGOD) in a dose-dependent manner.However,the anti-apoptotic effect of PNS was reversed by LY294002,a specific PI3K inhibitor.This antiapoptotic effect of PNS was confirmed by JC-1,a specific probe of mitochondrial membrane potential staining.PNS could significantly increase phos-Akt in H9c2 cells by Western blot assays and its effect could be inhibited by LY294002.Furthermore,PNS could improve ischemic-induced left ventricular function as reflected by EF,LVDd and LVDs.PNS could also inhibited cellular apoptosis in myocardial tissues in ischemic rats by TUNEL assay.PNS administration also increased the expression of phos-Akt in rat ischemic myocardial tissues.These results suggested that PNS could protect myocardial cells from apoptosis induced by ischemia in vitro model and in vivo model through activating-PI3K/Akt signal pathway which may be meaningful for further understanding the molecular mechanisms of cardiac protection of PNS.And the results might be useful in treatment of myocardial ischemia in future.

β3-adrenoceptor Impacts Apoptosis in Cultured Cardiomyocytes via Activation of PI3K/Akt and p38MAPK

β3-adrenoceptor（β3-AR） has been shown to promote myocardial apoptosis. However, the exact physiological role and importance of this receptor in the human myocardium, and its underlying mode of action, have not been fully elucidated. The present study aimed to determine the effects of β3-AR on the promotion of myocardial apoptosis and on norepinephrine（NE） injury. We analyzed NE-induced cardiomyocyte（CM） apoptosis by using a TUNEL and an annexin V/propidium iodide apoptosis assay. Furthermore, we investigated the NE-induced expression of the apoptosis marker genes Akt and p38 MAPK, their phosphorylated counterparts p-Akt and p-p38 MAPK, caspase-3, Bcl-2, and Bax. In addition, we determined the effect of a 48-h treatment with a β3-AR agonist and antagonist on expression of these marker genes. β3-AR overexpression was found to increase CM apoptosis, accompanied by an increased expression of caspase-3, bax/bcl-2, and p-p38 MAPK. In contrast, the β3-blocker reduced apoptosis of CMs and the associated elevated Akt expression. We identified a novel and potent anti-apoptosis mechanism via the PI3K/Akt pathway and a pro-apoptosis pathway mediated by p38 MAPK.

Effect of microRNA-208a on mitochondrial apoptosis of cardiomyocytes of neonatal rats

Objective: To explore the effect and mechanism of microRNA-208a(mi R-208a) in the mitochondrial apoptosis of cardiomyocytes of neonatal rats. Methods: The primary cultured cardiomyocytes of neonatal rats were added into the hypoxia incubator for the hypoxia induction. The overexpression system for mi R-208 a of cardiomyocytes of neonatal rats was built. The l ow cytometry assay was employed to detect the incidence of apoptosis in the overexpressed mi R-208 a. The mitochondrial staining technique was used to detect the change in the mitochondrial morphology of over-expressed mi R-208 a. The bioinformatic analysis was chosen to analyze and predict the target gene of mi R-208 a. Results: Firstly, the primary culture system of cardiomyocytes of neonatal rats was successfully built. The mi R-208 a was over-expressed in cardiomyocytes of neonatal rats by mi R-208 a Mimics. Results of flow cytometry assay showed that the over-expressed mi R-208 a could signii cantly reduce the incidence of apoptosis; while results of mitochondrial staining indicated the change in the mitochondrial morphology of over-expressed mi R-208 a and the mitochondrialfission process was inhibited. In conclusion, it was supposed that mi R-208 a could inhibit the activation of mitochondrialfission process to keep the cardiomyocytes from apoptosis. Conclusions: The over-expressed mi R-208 a can reduce the incidence of apoptosis in the cardiomyocytes of neonatal rats, signii cantly change the mitochondrial morphology and inhibit the mitochondrial fission process.

Overexpression of angiopoietin-1 reduces doxorubicin-induced apoptosis in cardiomyocytes

Doxorubicin （Dox） is a major anticancer chemotherapeutic agent. However, it causes cardiomyopathy due to the side effect of cardiomyocyte apoptosis. We have previously reported that angiopoietin-1 significantly reduced myocardial infarction after ischemic injury and protected cardiomyocytes from oxidative stress-induced apoptosis. It is hypothesized that angiopoietin-1 may protect cardiomyocytes from Dox-induced apoptosis. Cardiomyocytes H9C2 were transfected with adenovirus expressing angiopoietin-1 （Ad5-Ang-1） 24 h before the cells were chal- lenged with Dox at a concentration of 2 ~tmol/L. Ad5-GFP served as the vector control. Cardiomyocyte apoptosis was evaluated using Annexin V-FITC staining and caspase-3 and caspase-8 activity was determined by Western blotting. The results showed that Dox treatment significantly induced cardiomyocyte apoptosis as evidenced by the greater number of Annexin V-FITC stained cells and increases in caspase-3 and caspase-8 activity. In contrast, overexpression of angiopoietin-1 significantly prevented Dox-induced cardiomyocyte apoptosis. To elucidate the mechanisms by which angiopoietin-1 protected cells from Dox-induced apoptosis, we analyzed both extrinsic and intrinsic apoptotic signaling pathways. We observed that angiopoietin-1 prevented Dox-induced activation of both extrinsic and intrinsic apoptotic signaling pathways. Specifically, angiopoietin-1 prevented DOX-induced in- creases in FasL and Bax levels and cleaved caspase-3 and caspase-8 levels in H9C2 cells. In addition, overexpres- sion of angiopoietin-1 also activated the pro-survival phosphoinositide-3 kinase （PI3K）/Akt signaling pathway and decreased Dox-induced nuclear factor-kappaB （NF-~：B） activation. Our data suggest that promoting the expression of angiopoietin-1 could be a potential approach for reducing Dox-induced cardiomyocyte cytoxicity.

Sanguinarine Attenuates Lipopolysaccharide-induced Inflammation and Apoptosis by Inhibiting the TLR4/NF-KB Pathway in H9c2 Cardiomyocytes

The inflammatory response is involved in the pathogenesis of the most common types of heart disease. Sanguinarine （SAN） has various pharmacological properties such as anti-inflammatory, antioxidant, antibacterial, antitumor, and immune-enhancing properties. However, few studies have investigated the effects of SAN on lipopolysaceharide （LPS）-induced inflammatory and apoptotic responses in H9c2 cardiomyocytes. Therefore, in this study, H9c2 cells were co-treated with SAN and LPS, and the mRNA levels of pro-inflammation markers and the apoptosis rate were measured to clarify the effect of SAN on cardiac inflammation. The underlying mechanism was further investigated by detecting the activation of Toll-like receptor （TLR）4/nuclear faetor-κB （NF-κB） signaling pathways. As a result, increased mRNA expression of interleukin （IL）-1β, IL-6, and TNFα induced by LPS was attenuated after SAN treatment; LPS-induced apoptosis ofHge2 cardiomyocytes and cleaved-caspase 8, 9, 3 were all significantly reduced by SAN. Further experiments showed that the beneficial effect of SAN on blocking the inflammation and apoptosis of H9c2 cardiomyocytes induced by LPS was associated with suppression of the TLR4/NF-κB signaling pathway. It was suggested that SAN suppressed the LPS-induced inflammation and apoptosis of H9c2 cardiomyocytes, which may be mediated by inhibition of the TLR4/NF-κB signaling pathway. Thus, SAN may be a feasible therapy to treat sepsis patients with cardiac dysfunction.

Activation of calcium-sensing receptors is associated with apoptosis in a model of simulated cardiomyocytes ischemia/reperfusion

Objective： Calcium-sensing receptors （CaSRs） are G-protein coupled receptors which maintain systemic calcium homeostasis and participate in hormone secretion, activation of ion channels, cell apoptosis, proliferation, and differentiation. Previous studies have shown that CaSRs induce apoptosis in isolated adult rat heart and in normal neonatal rat cardiomyocytes by G-protein-PLC-IP3 signaling transduction. However, little knowledge is presently available concerning the role of CaSRs in the apoptosis induced by ischemia and reperfusion in neonatal cardiomyocytes. Methods： Primary neonatal rat ventricular cardiomyocytes were incubated in ischemiamimetic solution for 2 h, and then re-incubated in normal culture medium for 24 h to establish a model of simu- lated ischemia/reperfusion （I/R）. Cardiomyocyte apoptosis was detected by terminal deoxynucleotidyl transferase- mediated dUTP nick end labeling （TUNEL）. The expression of CaSRs mRNA was detected by real-time reverse transcription polymerase chain reaction （RT-PCR）. In addition, the expressions of caspase-3 and Bcl-2 were analyzed by western blot. Results： The simulated I/R enhanced the expression of CaSRs and cardiomyocyte apoptosis. GdCl3, a specific activator of CaSRs, further increased the expression of CaSRs and cardiomyocyte apoptosis, along with up-regulation of caspase-3 and down-regulation of Bcl-2. Conclusion： CaSRs are associated with UR injury and apoptosis in neonatal rat ventricular cardiomyocytes via suppressing Bcl-2 and promoting caspase-3 expression.

Effects of Hypoxia on Oxidative Stress, Autophagy and Apoptosis in Cardiomyocytes

Coronary heart disease (CHD) is a hypoxia related disease. However, the relationship of the hypoxia-induced oxidative stress, autophagy and apoptosis in cardiomyocyte remains unclear. In this study, we used CoCl2 to mimic hypoxic conditions in H9c2 cardiomyocytes and study the effects of CoCl2-induced hypoxia on oxidative stress, apoptosis and autophagy, as well as the relationships among these processes. Cell viability and levels of ROS, LC3-II, p62, caspase-3 and PARP were assessed. The viability and morphology of cardiomyocytes were affected by hypoxia, and hypoxia enhanced levels of ROS and the levels of the LC3-II, p62, caspase-3 and PARP proteins in H9c2 cells in a dose-dependent manner. ROS levels rise gradually in the presence of hypoxia;however, it shrinks when hypoxia reaches a certain level. Caspase-3 and PARP levels were raised with the increasing of hypoxia level. Enhanced level of LC3 and decreased levels of p62 in hypoxic cells indicate that autophagy levels are in accord with hypoxia. Based on these results, hypoxia induces oxidative stress, apoptosis and autophagy in cardiomyocytes. Autophagy is a double-edged sword. At a low level, autophagy can resist oxidative stress and protect cardiomyocytes from oxidative stress, while high level autophagy can promote apoptosis of cardiomyocytes.

MicroRNA-34a Regulates High Glucose-induced Apoptosis in H9c2 Cardiomyocytes

Hyperglycemia is an important initiator of cardiovascular disease, contributing to the de- velopment of cardiomyocyte death and diabetic complications. The purpose of the present study was to investigate whether high glucose state could induce apoptosis of rat cardiomyocyte cell line H9c2 through microRNA-mediated Bcl-2 signaling pathway. The expression of miR-34a and Bcl-2 mRNA was detected by using real-time PCR. Western blotting was used to examine the changes in apop- tosis-associated protein Bcl-2. Apoptosis of H9c2 cells was tested by using flow cytometry. The results showed that the expression of miR-34a was significantly elevated and that of Bcl-2 was strongly re- duced, and apoptosis of cardiomyocytes was apparently increased in the high-glucose-treated H9c2 cells as compared with normal-glucose-treated controls. In addition, we identified Bcl-2 gene was the target of miR-34a, miR-34a mimics reduced the expression of Bcl-2 and increased glucose-induced apoptosis, but miR-34a inhibitor acted as the opposite mediator. Our data demonstrate that miR-34a contributes to high glucose-induced decreases in Bcl-2 expression and subsequent cardiomyocyte apoptosis.

Nonhematopoietic erythropoietin derivative protects cardiomyocytes from hypoxia/reoxygenation-induced apoptosis

Objective：Carbamylated EPO（CEPO） is a derivative of erythropoietin（EPO） by subjecting it to carbamylation. It does not stimulate erythropoiesis, but effectively protects tissue from injury. The present study was to investigate the effect of CEPO treatment using in vitro models of hypoxia/reoxygenation（H/R）. Methods：Cardiomyocytes were exposed to hypoxia（95% N2 and 5% CO2） for 1 hour followed by 4 hours of reoxygenation（95% O2 and 5% CO2）. CEPO was administered after hypoxia, just before reoxygenation. The apoptotic cardiomyocytes were determined by flow cytometry. The level of protein was assessed by western blot analysis. Results： CEPO treatment significantly decreased the apoptotic cardiomyocytes by 54.20% compared with H/R group. Western blot analysis showed that CEPO administration increased the level of Bcl-2（an antiapoptotic protein） by 62.22% compared with H/R group. Conclusion： Acute administration of CEPO protected cardiomyocytes from H/R-induced apoptosis. CEPO protected cardiomyocytes with a concomitant upregulation of Bcl-2 after H/R injury.

Influence of Silencing Soluble Epoxide Hydrolase with RNA Interference on Cardiomyocytes Apoptosis Induced By Doxorubicin

In order to investigate the influence of silencing soluble epoxide hydrolase（sEH） with double-stranded small interfering RNA（siRNA） on cardiomyocytes apoptosis induced by doxorubicin（DOX）,two plasmids containing siRNA sequences specific to sEH were constructed and transfected into the primary cultured cardiomyocytes by using FuGENE HD transfection agents.The mRNA and protein expression levels of sEH were detected by semiquantitative RT-PCR and Western blotting respectively,and the plasmids that silenced sEH most significantly were selected,and renamed EH-R.The plasmids carrying a nonspecific siRNA coding sequence（PCN） served as the negative control.Cardiomyocytes were divided into four groups：control group,DOX group,PCN＋DOX group,and EH-R＋DOX group.Apoptosis of cardiomyocytes was induced by DOX at a concentration of 1 μmol/L.Apoptosis rate of cardiomyocytes was determined by flow cytometery.The protein expression levels of Bcl-2 and Bax were detected by Western blotting.The results showed that the expression of sEH was down-regulated by EH-R plasmid.The expression levels of sEH mRNA and protein in the EH-R＋DOX group were significantly decreased as compared with other groups（P0.01）.As compared with the control group,the apoptosis rate of cardiomyocytes in three DOX-treated groups was obviously increased,the expression levels of Bax increased,and those of Bcl-2 decreased（P0.01）.However,the expression levels of Bax were decreased,those of Bcl-2 increased and the apoptosis rate of cardiomyocytes obvi-ously decreased in EH-R＋DOX group when compared with those in the DOX group and the PCN＋DOX group（P0.01 for each）.It was concluded that the recombinant plasmids could be successfully constructed,and transfected into the primary cultured cardiomyocytes.They could ameliorate the DOX-induced cardiomyocytes apoptosis by selectively inhibiting the expression of sEH with RNAi and increasing the expression of Bcl-2.

miR-208a Promotes Apoptosis in H9c2 Cardiomyocytes by Targeting GATA4

Background:microRNAs are crucial for cardiovascular development and are associated with congenital heart disease(CHD).Recent studies have shown that microRNAs play a role in heart development and is closely related to CHD.The present study investigated the underlying mechanism of microRNA-208a(miR-208a)in“simple”CHD.Material and Methods:Reverse transcription-quantitative PCR(RT-qPCR)demonstrated miR-208a expression levels in children with CHD(n=27)compared with normal controls(n=29),in cardiomyocytes from embryo 10(E10)to post-birth(P7)and organs in adult rats in healthy rats.Apoptosis of H9c2 cells after transfection with miR-208a detected by TUNEL assay.B-cell lymphoma(Bcl)-2,an anti-apoptotic gene,was detected by RT-qPCR,as well as Gata4.After 48h overexpression of miR-208a,GATA4 was detected via western blotting.Dual luciferase reporting system was used to identify the binding sites of miR-208a to Gata4.Results:Expression of miR-208a was upregulated in the CHD group via the control group(p<0.01).At P7,miR-208a had the highest expression(p<0.01),and which was highest in myocardiocytes via other organs or tissues(p<0.01)in adult rats.The number of apoptotic cells increased significantly post-transfection with miR-208a(p<0.01),while decreased with the miR-208a inhibitor via the control group(p<0.01).Compared with the control group,there was no significant difference in the expression level of Bcl-2 after miR-208a overexpression(p>0.05).The present study proved that miR-208a binds directly to the 3´-UTR of Gata4 at site 1,363-1,369 bp.Expression of GATA4 decreased after miR-208a overexpression(p<0.01),but increased following transfection with a miR-208a inhibitor via the control group(p<0.05).Conclusions:Our study demonstrated that miR-208a downregulates Bcl-2 by directly targeting GATA4,which may cause CHD.miR-208a may become a new biomarker or therapeutic target for CHD in the future.

Mechanical stretch induces mitochondria-dependent apoptosis in neonatal rat cardiomyocytes and G_(2)/M accumulation in cardiac fibroblasts

Heart remodeling is associated with the loss of cardiomyocytes and increase of fibrous tissue owing to abnormal mechanical load in a number of heart disease conditions. In present study,a well-described in vitro sustained stretch model was employed to study mechanical stretch-induced responses in both neonatal cardiomyocytes and cardiac fibroblasts. Cardiomyocytes,but not cardiac fibroblasts,underwent mitochondria-dependent apoptosis as evidenced by cytochrome c (cyto c) and Smac/DIABLO release from mitochondria into cytosol accompanied by mitochondrial membrane potential (△ψm) reduction,indicative of mitochondrial permeability transition pore (PTP)opening. Cyclosporin A,an inhibitor of PTP,inhibited stretch-induced cyto c release,△ψm reduction and apoptosis,suggesting an important role of mitochondrial PTP in stretch-induced apoptosis. The stretch also resulted in increased expression of the pro-apoptotic Bcl-2 family proteins,including Bax and Bad,in cardiomyocytes,but not in fibroblasts. Bax was accumulated in mitochondria following stretch. Cell permeable Bid-BH3 peptide could induce and facilitate stretch-induced apoptosis and △ψm reduction in cardiomyocytes. These results suggest that Bcl-2 family proteins play an important role in coupling stretch signaling to mitochondrial death machinery,probably by targeting to PTP. Interestingly,the levels of p53 were increased at 12 h after stretch although we observed that Bax upregulation and apoptosis occurred as early as 1 h. Adenovirus delivered dominant negative p53 blocked Bax upregulation in cardiomyocytes but showed partial effect on preventing stretch-induced apoptosis,suggesting that p53 was only partially involved in mediating stretch-induced apoptosis. Furthermore,we showed that p21 was upregulated and cyclin B l was downregulated only in cardiac fibroblasts,which may be associated with G2/M accumulation in response to mechanical stretch.

Dihydroartemisinin ameliorates palmitate-induced apoptosis in cardiomyocytes via regulation on miR-133b/Sirt1 axis

Excessive fat ectopically deposited in the non-adipose tissues is considered as one of the leading causes of myopathy.The aim of this study was to investigate the role of Dihydroartemisinin(DHA)in palmitate(PAL)-incubated H9c2 cells(lipotoxicity-induced cell injury model).Cell viability of PAL-treated cells was determined by MTT assay,and apoptotic regulators were examined by qRT-PCR and western blot analysis,in the absence or in the presence of DHA,respectively.Expression levels of miR-133b and Sirt1 were also evaluated by qRT-PCR and western blotting examination.PAL decreased the viability of H9c2 cells and enhanced the expression of apoptotic genes.DHA reversed the effect of PAL on cell viability and lowed the level of Caspase3 and Bax.It also lowered the expression of miR-133b,while enhanced the expression of Bcl-2.Sirt1 was revealed as target of miR-133b through transcriptional regulation and the process was affected by DHA.DHA partially protected against the PAL-induced lipotoxicity by influencing the expression of miR-133b that hindered the activity of Sirt1.DHA may be used as a potential treatment in clinical management for lipotoxicity induced heart complications.
