    Necroptosis, necrosis characterized by RIPK3-MLKL activation, has been proposed as a mechanism of doxorubicin (DOX)-induced cardiomyopathy. We showed that rapamycin, an mTORC1 inhibitor, attenuates cardiomyocyte necroptosis. Here we examined role of MLKL in DOX-induced myocardial damage and protective effects of rapamycin. Cardiomyopathy was induced in mice by intraperitoneal injections of DOX (10 mg/kg, every other day) and followed for 7 days. DOX-treated mice showed a significant decline in LVEF assessed by cardiac MRI (45.5 ± 5.1% vs. 65.4 ± 4.2%), reduction in overall survival rates, and increases in myocardial RIPK3 and MLKL expression compared with those in vehicle-treated mice, and those changes were prevented by administration of rapamycin (0.25 mg/kg) before DOX injection. In immunohistochemical analyses, p-MLKL signals were detected in the cardiomyocytes of DOX-treated mice, and the signals were reduced by rapamycin. Mlkl+/- and Mlkl-/- mice were similarly resistant to DOX-induced cardiac dysfunction, indicating that a modest reduction in MLKL level is sufficient to prevent the development of DOX-induced cardiomyopathy. However, evidence of cardiomyocyte necrosis assessed by C9 immunostaining, presence of replacement fibrosis, and electron microscopic analyses was negligible in the myocardium of DOX-treated mice. Thus, MLKL-mediated signaling contributes to DOX-induced cardiac dysfunction primarily by a necrosis-independent mechanism, which is inhibitable by rapamycin.

    Necroptosis, a form of necrosis, and alterations in mitochondrial dynamics, a coordinated process of mitochondrial fission and fusion, have been implicated in the pathogenesis of cardiovascular diseases. This study aimed to determine the role of mitochondrial morphology in canonical necroptosis induced by a combination of TNFα and zVAD (TNF/zVAD) in H9c2 cells, rat cardiomyoblasts. Time-course analyses of mitochondrial morphology showed that mitochondria were initially shortened after the addition of TNF/zVAD and then their length was restored, and the proportion of cells with elongated mitochondria at 12 h was larger in TNF/zVAD-treated cells than in non-treated cells (16.3 ± 0.9% vs. 8.0 ± 1.2%). The knockdown of dynamin-related protein 1 (Drp1) and fission 1, fission promoters, and treatment with Mdivi-1, a Drp-1 inhibitor, had no effect on TNF/zVAD-induced necroptosis. In contrast, TNF/zVAD-induced necroptosis was attenuated by the knockdown of mitofusin 1/2 (Mfn1/2) and optic atrophy-1 (Opa1), proteins that are indispensable for mitochondrial fusion, and the attenuation of necroptosis was not canceled by treatment with Mdivi-1. The expression of TGFβ-activated kinase (TAK1), a negative regulator of RIP1 activity, was upregulated and the TNF/zVAD-induced RIP1-Ser166 phosphorylation, an index of RIP1 activity, was mitigated by the knockdown of Mfn1/2 or Opa1. Pharmacological TAK1 inhibition attenuated the protection afforded by Mfn1/2 and Opa1 knockdown. In conclusion, the inhibition of mitochondrial fusion increases TAK1 expression, leading to the attenuation of canonical necroptosis through the suppression of RIP1 activity.

    AIMS/INTRODUCTION: We previously showed that upregulation of myocardial adenosine monophosphate deaminase (AMPD) is associated with pressure overload-induced diastolic dysfunction in type 2 diabetes hearts. Here, we examined involvement of AMPD localized in the endoplasmic reticulum-mitochondria interface in mitochondrial Ca2+ overload and its pathological significance. MATERIALS AND METHODS: We used type 2 diabetes Otsuka Long-Evans Tokushima Fatty rats (OLETF) and non-diabetes Long-Evans Tokushima Otsuka Fatty rats (LETO) as well as AMPD3-overexpressing H9c2 cells and human embryonic kidney 293 cells. RESULTS: OLETF, but not LETO, showed diastolic dysfunction under the condition of phenylephrine-induced pressure overload. The levels of 90-kDa AMPD3 in outer mitochondrial membranes/endoplasmic reticulum and mitochondria-associated endoplasmic reticulum membrane (MAM) fractions were significantly higher in OLETF than in LETO. The area of the MAM quantified by electron microscopic analysis was 57% larger, mitochondrial Ca2+ level under the condition of pressure overload was 47% higher and Ca2+ retention capacity in MAM-containing crude mitochondria isolated before the pressure overloading was 21% lower in OLETF than in LETO (all P-values <0.05). Transfection of FLAG-AMPD3 in cells resulted in significant enlargement of the MAM area, and impairment in pyruvate/malate-driven adenosine triphosphate-stimulated and uncoupler-stimulated mitochondrial respiration compared with those in control cells. CONCLUSIONS: The findings suggest that 90-kDa AMPD3 localized in the endoplasmic reticulum-mitochondria interface promotes formation of the MAM, inducing mitochondrial Ca2+ overload and dysfunction in type 2 diabetes hearts.

    Systemic branched-chain amino acid (BCAA) metabolism is dysregulated in cardiometabolic diseases. We previously demonstrated that upregulated AMP deaminase 3 (AMPD3) impairs cardiac energetics in a rat model of obese type 2 diabetes, Otsuka Long-Evans-Tokushima fatty (OLETF). Here, we hypothesized that the cardiac BCAA levels and the activity of branched-chain α-keto acid dehydrogenase (BCKDH), a rate-limiting enzyme in BCAA metabolism, are altered by type 2 diabetes (T2DM), and that upregulated AMPD3 expression is involved in the alteration. Performing proteomic analysis combined with immunoblotting, we discovered that BCKDH localizes not only to mitochondria but also to the endoplasmic reticulum (ER), where it interacts with AMPD3. Knocking down AMPD3 in neonatal rat cardiomyocytes (NRCMs) increased BCKDH activity, suggesting that AMPD3 negatively regulates BCKDH. Compared with control rats (Long-Evans Tokushima Otsuka [LETO] rats), OLETF rats exhibited 49% higher cardiac BCAA levels and 49% lower BCKDH activity. In the cardiac ER of the OLETF rats, BCKDH-E1α subunit expression was downregulated, while AMPD3 expression was upregulated, resulting in an 80% lower AMPD3-E1α interaction compared to LETO rats. Knocking down E1α expression in NRCMs upregulated AMPD3 expression and recapitulated the imbalanced AMPD3-BCKDH expressions observed in OLETF rat hearts. E1α knockdown in NRCMs inhibited glucose oxidation in response to insulin, palmitate oxidation, and lipid droplet biogenesis under oleate loading. Collectively, these data revealed previously unrecognized extramitochondrial localization of BCKDH in the heart and its reciprocal regulation with AMPD3 and imbalanced AMPD3-BCKDH interactions in OLETF. Downregulation of BCKDH in cardiomyocytes induced profound metabolic changes that are observed in OLETF hearts, providing insight into mechanisms contributing to the development of diabetic cardiomyopathy.

  • Nuclear translocation of MLKL enhances necroptosis by a RIP1/RIP3-independent mechanism in H9c2 cardiomyoblasts. Reviewed

    Accumulating evidence suggests that necroptosis of cardiomyocytes contributes to cardiovascular diseases. Lethal disruption of the plasma membrane in necroptosis is induced by oligomers of mixed lineage kinase domain-like (MLKL) that is translocated to the membrane from the cytosol. However, the role played by cytoplasmic-nuclear shuttling of MLKL is unclear. Here, we tested the hypothesis that translocation of MLKL to the nucleus promotes the necroptosis of cardiomyocytes. Activation of the canonical necroptotic signaling pathway by a combination of TNF-α and zVAD (TNF/zVAD) increased nuclear MLKL levels in a RIP1-activity-dependent manner in H9c2 cells, a rat cardiomyoblast cell line. By use of site-directed mutagenesis, we found a nuclear export signal sequence in MLKL and prepared its mutant (MLKL-L280/283/284A), though a search for a nuclear import signal was unsuccessful. MLKL-L280/283/284A localized to both the cytosol and the nucleus. Expression of MLKL-L280/283/284A induced necroptotic cell death, which was attenuated by GppNHp, an inhibitor of Ran-mediated nuclear import, but not by inhibition of RIP1 activity or knockdown of RIP3 expression. GppNHp partly suppressed H9c2 cell death induced by TNF/zVAD treatment. These results suggest that MLKL that is translocated to the nucleus via RIP1-mediated necroptotic signaling enhances the necroptosis of cardiomyocytes through a RIP1-/RIP3-independent mechanism.

    Background:

    Fulminant myocarditis presentation (FMP) is a rare and severe presentation of myocarditis. The natural history of FMP and its clinical features associated with poor outcomes are incompletely understood because there is a lack of generalizable evidence.

    Methods:

    This multicenter retrospective cohort study included patients hospitalized with histologically proven myocarditis who underwent catecholamine or mechanical support from 235 cardiovascular training hospitals across Japan between April 2012 and March 2017. Clinical features and the prognostic predictors of death or heart transplantation within 90 days on the basis of clinical and pathologic findings were determined using the Kaplan-Meier method, log-rank test, and Cox regression analysis.

    Results:

    This study included 344 patients with histologically proven FMP (median age, 54 years; 40% female). The median follow-up was 600 days (interquartile range, 36 to 1599 days) and the cumulative risk of death or heart transplantation at 90 days was 29% (n=98). Results from multivariable Cox regression analysis showed that older age, nonsinus rhythm, low left ventricular wall motion (&lt;40%) on admission, and ventricular tachycardia or fibrillation on admission day were associated with worse 90-day survival. Severe histologic damage (damaged cardiomyocytes comprising ≥50% of the total cardiomyocytes) was associated with a worse 90-day prognosis in patients with lymphocytic myocarditis.

    Conclusions:

    The results from analyses of data from this multicenter registry demonstrated that patients with FMP are at a higher risk of death or heart transplantation in real-world settings. These observations inform which clinical and pathologic findings may be useful for prognostication in FMP.

    SIRT3 is an NAD+-dependent protein deacetylase localized in mitochondria. Several studies reported localization of SIRT3 in the cytoplasm or nucleus, but data of these studies were not consistent. We detected expression of mitochondrial (SIRT3mt) and cytoplasmic (SIRT3ct) Sirt3 mRNAs in the mouse brain, and we also found SIRT3 immunostaining of mitochondria and cytoplasm in the brain and cultured neural cells. However, expression levels of SIRT3ct in COS cells transfected with SIRT3ct cDNA were much lower than those of SIRT3mt. We found that SIRT3ct but not SIRT3mt was promptly degraded by ubiquitin-dependent degradation, in which SIRT3ct degradation was mediated mainly by ubiquitination of NH2-terminal methionine and partly by that of lysine residues of SIRT3ct. SIRT3ct expression level was significantly enhanced by the treatment of cells with staurosporine or H2O2. H2O2 treatment promoted nuclear translocation of SIRT3ct and induced histone H3 deacetylation and superoxide dismutase 2 expression. Overexpression of SIRT3ct decreased cell death caused by H2O2 at levels similar to those achieved by overexpression of SIRT3mt. Knockdown of Sirt3 mRNA increased cell death caused by amyloid-β (Aβ), and overexpression of SIRT3ct suppressed the toxic function of Aβ in PC12 cells. These results indicate that SIRT3ct promotes cell survival under physiological and pathological conditions.

    Multiple factors regulate glucagon-like peptide-1 (GLP-1) secretion, but a group of apparently healthy subjects showed blunted responses of GLP-1 secretion in our previous study. In this study, we examined whether the reduction in GLP-1 secretory capacity is associated with increased extent of coronary artery stenosis in non-diabetic patients. Non-diabetic patients who were admitted for coronary angiography without a history of coronary interventions were enrolled. Coronary artery stenosis was quantified by Gensini score (GS), and GS ≥ 10 was used as an outcome variable based on its predictive value for cardiovascular events. The patients (mean age, 66.5 ± 8.8 years; 71% males, n = 173) underwent oral 75 g-glucose tolerant tests for determination of glucose, insulin and active GLP-1 levels. The area under the curve of plasma active GLP-1 (AUC-GLP-1) was determined as an index of GLP-1 secretory capacity. AUC-GLP-1 was not correlated with fasting glucose, AUC-glucose, serum lipids or indices of insulin sensitivity. In multivariate logistic regression analysis for GS ≥ 10, AUC-GLP-1 < median, age and hypertension were selected as explanatory variables, though fasting GLP-1 level was not selected. The findings suggest that reduction in GLP-1 secretory capacity is a novel independent risk factor of coronary stenosis.

    BACKGROUND: The risk of contrast-induced nephropathy (CIN) is high in patients with chronic kidney disease (CKD). However, the mechanism of CIN in CKD is not fully understood. Here, we prepared a clinically relevant model of CIN and examined the role of necroptosis, which potentially cross-talks with autophagy, in CIN. METHODS: In Sprague-Dawley rats, CKD was induced by subtotal nephrectomy (SNx, 5/6 nephrectomy) 4 weeks before induction of CIN. CIN was induced by administration of a contrast medium (CM), iohexol, following administration of indomethacin and N-omega-Nitro-L-arginine methyl ester. Renal function and tissue injuries were assessed 48 h after CM injection. RESULTS: Serum creatinine (s-Cre) and BUN were increased from 0.28 ± 0.01 to 0.52 ± 0.02 mg/dl and from 15.1 ± 0.7 to 29.2 ± 1.2 mg/dl, respectively, after SNx alone. CM further increased s-Cre and BUN to 0.69 ± 0.03 and 37.2 ± 2.1, respectively. In the renal tissue after CM injection, protein levels of receptor-interacting serine/threonine-protein kinase (RIP) 1, RIP3, cleaved caspase 3, and caspase 8 were increased by 64 ~ 212%, while there was reduction in LC3-II and accumulation of p62. Necrostatin-1, an RIP1 inhibitor, administered before and 24 h after CM injection significantly suppressed elevation of s-Cre, BUN and urinary albumin levels, kidney injury molecule-1 expression and infiltration of CD68-positive macrophages in renal tissues after CM injection. CONCLUSION: The results suggest that necroptosis of proximal tubular cells contributes to CIN in CKD and that suppression of protective autophagy by pro-necroptotic signaling may also be involved.

    BACKGROUND: We previously reported that upregulated AMP deaminase (AMPD) contributes to diastolic ventricular dysfunction via depletion of the adenine nucleotide pool in a rat model of type 2 diabetes (T2DM), Otsuka Long-Evans-Tokushima Fatty rats (OLETF). Meanwhile, AMPD promotes the formation of substrates of xanthine oxidoreductase (XOR), which produces ROS as a byproduct. Here, we tested the hypothesis that a functional link between upregulated AMPD and XOR is involved in ventricular dysfunction in T2DM rats. METHODS AND RESULTS: Pressure-volume loop analysis revealed that pressure overloading by phenylephrine infusion induced severer left ventricular diastolic dysfunction (tau: 14.7 ± 0.8 vs 12.5 ± 0.7 msec, left ventricular end-diastolic pressure: 18.3 ± 1.5 vs 12.2 ± 1.3 mmHg, p < 0.05) and ventricular-arterial uncoupling in OLETF than in LETO, non-diabetic rats, though the baseline parameters were comparable in the two groups. While the pressure overload did not affect AMPD activity, it increased XOR activity both in OLETF and LETO, with OLETF showing significantly higher XOR activity than that in LETO (347.2 ± 17.9 vs 243.2 ± 6.1 μg/min/mg). Under the condition of pressure overload, myocardial ATP level was lower, and levels of xanthine and uric acid were higher in OLETF than in LETO. Addition of exogenous inosine, a product of AMP deamination, to the heart homogenates augmented XOR activity. OLETF showed 68% higher tissue ROS levels and 47% reduction in mitochondrial state 3 respiration compared with those in LETO. Overexpression of AMPD3 in H9c2 cells elevated levels of hypoxanthine and ROS and reduced the level of ATP. Inhibition of XOR suppressed the production of tissue ROS and mitochondrial dysfunction and improved ventricular function under the condition of pressure overload in OLETF. CONCLUSIONS: The results suggest that increases in the activity of XOR and the formation of XOR substrates by upregulated AMPD contribute to ROS-mediated diastolic ventricular dysfunction at the time of increased cardiac workload in diabetic hearts.

    The present study evaluated the accuracy of interstitial glucose measurements by flash glucose monitoring (FGM) and continuous glucose monitoring (CGM). Five diabetes patients simultaneously underwent FGM (FreeStyle Libre Pro) and CGM (iPro™2), and their glucose levels were compared with venous blood and capillary blood glucose levels. The range of daily venous blood glucose levels (30 measurements) was 70-245 mg/dL, with a median of 138 mg/dL. There were good correlations of glucose levels measured by FGM (r2  = 0.90, mean absolute relative difference 8.2 ± 5.6%), CGM (r2  = 0.86, mean absolute relative difference 9.2 ± 9.1%) and capillary blood (r2  = 0.87, mean absolute relative difference 7.2 ± 7.2%) with venous blood glucose levels. The accuracy of FGM measurements was also shown against CGM, with 99.9% of the FGM values (1,279 measurements) being within the Parkes error grid zones A and B. The results suggest that the accuracy of FGM is similar to that of CGM, and that FGM is a useful tool for determining daily glucose profile.

    糖尿病性心筋症は発症早期には左室拡張機能障害を呈する。我々は肥満2型糖尿病モデルラットであるOLETFの左室心筋を用い、糖尿病合併心筋において、AMP deaminase (AMPD) 活性亢進によるATPレベルの低下と酸化ストレス増加が拡張能機能障害に寄与することから、AMPD活性制御が糖尿病性心筋症の新たな治療標的になり得ることを報告した。本研究ではAMPDの細胞内局在に着目して検討を行なっている。
    左室心筋各細胞分画におけるAMPDの局在をウェステンブロット法で解析したところ、主要なアイソフォームである90-kDa AMPD3はOLETFにおいて非糖尿病対照ラットであるLETOと比較して小胞体や小胞体-ミトコンドリア接触(MAM)領域においてその発現レベルが有意に上昇していた。電子顕微鏡による観察では心筋のMAM領域はOLETFにおいてLETOと比較して有意に広かった。また、H9c2細胞においてFLAG-AMPD3をトランスフェクションしたところ、対照ベクターと比較して有意にMAM領域が広くなったことから、OLETFにおけるMAM領域の拡大はAMPD3発現増加が関与する可能性が示唆された。左室後負荷を増大させた状態で採取した心筋ミトコンドリアのCa2+濃度はOLETFにおいてLETOよりも有意に高く、AMPD3を過剰発現したH9c2細胞のミトコンドリアにおいてもCa2+濃度が上昇した。さらに、H9c2細胞において過酸化水素暴露によるミトコンドリア膜電位の低下はAMPD3の過剰発現で増悪し、発現抑制で軽減した。細胞外フラックスアナライザーを用いた解析ではAMPD過剰発現によりミトコンドリア呼吸鎖複合体Iの機能異常が生じた。これらの成績からMAMに局在するAMPD3は、そのレベルが過剰になるとミトコンドリアカルシウム負荷による機能異常を惹起すると考えられる。

    We found increased cardiomyocyte expression of nuclear p-MLKL, an executor of necroptosis, in patients with nonischemic dilated cardiomyopathy (NICM), but its clinical significance remains unclear. Endomyocardial biopsy specimens were obtained from 57 patients with NICM (56±15 years old, 68% male). Nuclear p-MLKL levels were determined by immunostaining against phospho-Ser358-MLKL. Using median nuclear p-MLKL expression levels, patients were classified into a high nuclear p-MLKL group and a low nuclear p-MLKL group. Adverse event was defined as composite of death or admission for heart failure or ventricular arrhythmia. Results of Kaplan-Meier survival curve analyses showed that the adverse event-free survival rate was lower in the high nuclear p-MLKL group than in the low nuclear p-MLKL group (4% vs. 31%, p=0.021). Enhanced expression of nuclear p-MLKL in cardiomyocytes predicts future adverse events, suggesting possible involvement of necroptosis in progression of NICM.

    This study examined if necroptosis of cardiomyocytes contributes to progression of chronic heart failure and if dysregulation of lysosomes in autophagy is involved in necroptotic death of cardiomyocytes. Results of experiments using isolated cardiomyocytes indicated that inflammatory cytokines, but not other humoral factors, mainly trigger necroptotic signaling and that there are two mechanisms of necroptotic cell death downstream of the signaling, cell membrane damages and suppression of autophagy via inhibition of a master transcriptional factor of lysosomes, in cardiomyocytes. Involvement of necroptotic signaling in chronic heart failure was supported by results of immun-ohistochemical analysis of endomyocardial biopsies from patients.

    The role of AMP deaminase (AMPD) in the left ventricular diastolic dysfunction in diabetic cardiomyopathy has been examined. Activity of AMPD was upregulated in the myocardium of type 2-diabetic rats, contributing to the manifestation of latent diastolic dysfunction via depletion of adenine nucleotide pool and ATP. Furthermore, we found that the activity of AMPD is regulated by microRNA 301b-mediated translational modification of ts protein expression level. Finally, AMPD3 also elevated the level of IMP and its downstream purine metabolic pathway molecules, substrates of xanthine oxidase (XO), resulting in production of excess reactive oxygen species (ROS) via XO-mediated reaction. The increased ROS aggravated the state 3 respiration of the mitochondria and suppressed ATP production. These finding indicate that upregulation of AMPD induced left ventricular diastolic dysfunction of diabetic hearts through both excess ATP degradation and insufficient ATP production.

    Significant roles of mTOR complex 1 (mTORC1) in heart failure have been shown in animal models of heart failure. However, contribution of mTORC1 to pathogenesis of human heart failure has not been characterized. By use of endomyocardial biopsy specimens, we found that mTORC1 activity was higher in patients with heart failure than in controls. Furthermore, autophagy in cardiomyocytes was impaired by activation of necroptotic signals via suppression of autolysosome formation. Inhibition of mTORC1 by rapamycin restored the autophagic flux in cardiomyocytes. The effect of rampamycin was mediated by novel inhibitory phosphorylation of RIP1 and led to cardiomyocyte protection from necroptosis. Taken together, the findings suggest that aberrant mTORC1 activation is a therapeutic target in heart failure.

    We investigated the molecular mechanisms by which activity of GSK-3beta promotes opening of mitochondrial permeability transition pore (mPTP). The experiments yielded the following results:
    (1) Interaction of GSK-3beta with voltage dependent anion channel 2 mediate mitochondrial translocation of GSK-3beta. (2) Lysine 15 at the N terminus of GSK-3beta plays an important role in the function of N-terminal region as a mitochondria targeting signal. (3) ERK and Akt, upstream kinases of GSK-3beta, translocate to the mitochondria and are dephosphorylated in response to oxidative stress. (4) Dusp5 and PHLPP-1, specific phosphatases for ERK and Akt, respectively, also undergo mitochondrial translocation under oxidative stress.

    This study showed that, in contrast to its role in necrosis, mitochondrial permeability transition (MPT) does not directly trigger cell death in necroptosis of cardiomyocytes and that necroptotic signals significantly inhibit autophagy, which is potentially modulated by MPT, leading to exaggeration of necroptotic cardiomyocyte death. Sequestration of p62 from p62-LC3-II interaction by increased p62-RIP1 interaction and inhibition of fusion of autophagosomes with lysosomes were proposed to be mechanisms by which necroptotic signals inhibits autophagy.

    The aim of this study was to characterize roles of protein kinases in regulation of mitochondrial permeability transition pore (mPTP) opening. We found that interaction of cyclophilin D (CypD) and inorganic phosphate carrier (PiC) determines the threshold for mPTP opening and that translocation of GSK-3beta via its interaction with VDAC2 and subsequent interaction with complex III promotes mPTP opening by enhanced production of reactive oxygen species. Inactivation of GSK-3beta by PI3K-Akt signaling or by activation of the mitochondrial KATP channel was found to increase threshold for mPTP opening and also to accelerate re-closure of opened mPTP, leading to protection from cell necrosis.

    Nuclear translocation of SIRT1 suppresses cardiomyocyte death in failing hearts. We demonstrated that phosphorylation of Ser517 of SIRT1 by Akt/PI3K contributed to the nuclear translocation. Furthermore, we identified proteins whose binding to SIRT1 change during oxidative stress, using immunoprecipitation, 2D gel electrophoresis and mass spectrometry. The physiological significance of the protein-protein interaction is currently under investigation. To translate the cardioprotective function of activation or nuclear translocation of SIRT1, we first analyzed a characteristics of OLETF rats, obese insulin-resistant type 2 diabetes rats, as an in vivo animal model for heart failure. In this model, diastolic dysfunction was induced under pressure overload, but not physiological conditions, and the mechanisms that trigger the functional impairment was explored in detail. We are currently investigating whether and how SIRT1 modifies the development of diastolic dysfunction.

    This study aimed to clarify role of connexin-43 (Cx43) in a major cytoprotective signaling, PI3K-Akt-GSK-3β signaling in cardiomyocytes. We found that Cx43 in the sarcolemma contributes to activation of class I_B P13K as a co-factor of β subunit of G proteins. This role of Cx43 is specific to regulation of class I_B P13K and is not required for activation of class I_A PI3K. Cx43 in mitochondria, being necessary for redox signaling by activated mitochondrial ATP-sensitive K^+ channel, was found to be dispensable in PI3K-Akt-GSK-3β signaling by G-protein coupled receptors.

    SIRT1 shuttled between the nuclei and cytoplasm. Nuclear SIRT1 suppressed oxidative stress-induced cell death by up-regulating Mn-SOD. SIRT1 accumulated in nuclei in cardiomyocytes of failing hearts probably as an endogenous adaptive mechanism and activation of SIRT1 by resveratrol reduced the mortality in cardiomyopathic hamsters. These findings suggest that SIRT1 activator may be a novel therapeutic approach for chronic heart failure.

    本研究では長寿蛋白ヒストン脱アセチル化酵素SIRT1の心不全での機能について検討し,一部の結果を既に報告した(J Biol Chem,2007)。さらに,その活性化薬レスベラトロールの心不全への効果をin vitro,in vivoの両面で検討中である。
    (1)SIRT1による細胞死の抑制
    EGFPにて標識した野生型SIRT1(WT),SIRT1の核移行シグナルに点変異を挿入することにより細胞質に局在するよう改変した変異体(mtNLS),または脱アセチル化酵素不活性変異体(H355Y)を作成し,親近し亜房に導入した。WT(核型)はアンチマイシンAやアンジオテンシンIIといった酸化ストレスによる細胞死を抑制するのに対して,この細胞保護効果はmtNLS(細胞質型)またはH355Yが導入された細胞では細胞保護効果は認められなかった。
    (2)SIRT1が酸化ストレスによる細胞死を抑制する機序
    WT(核型)およびmtNLS(細胞質型)をC2C12細胞に導入し内因性の酸化ストレス消去酵素の発現レベルを解析したところ,WT(核型)を導入した場合のみMnSODの発現が亢進した。またsiRNA法でMnSODの発現を抑制すると細胞死の抑制効果が消失した。
    (3)SIRT1活性化薬レスベラトロールの心不全に対する効果
    レスベラトロールを遺伝的拡張型心筋症の動物モデルであるTO2ハムスターに投与し,明らかな心不全が発症する生後35週齢の時点で通常の食餌のみを与えた個体と,心重量/体重比,左室心筋線維化,心筋BNPのmRNA発現,心エコーにより測定した左室駆出率を比較検討した。いずれの結果もレスベラトロールが心不全の重症度を軽減していた。
