Retinol Dehydrogenase 10 Reduction Mediated Retinol Metabolism Disorder Promotes Diabetic Cardiomyopathy in Male Mice.

ABSTRACT: In this study, we identify disordered cardiac retinol metabolism in type 2 diabetic male mice and patients characterized by retinol overload, all-trans retinoic acid deficiency. By supplementing type 2 diabetic male mice with retinol or all-trans retinoic acid, we demonstrate that both cardiac retinol overload and all-trans retinoic acid deficiency promote diabetic cardiomyopathy. Mechanistically, by constructing cardiomyocyte-specific conditional retinol dehydrogenase 10-knockout male mice and overexpressing retinol dehydrogenase 10 in male type 2 diabetic mice via adeno-associated virus, we verify that the reduction in cardiac retinol dehydrogenase 10 is the initiating factor for cardiac retinol metabolism disorder and results in diabetic cardiomyopathy. Therefore, we suggest that the reduction of cardiac retinol dehydrogenase 10 and its mediated disorder of cardiac retinol metabolism is a new mechanism underlying diabetic cardiomyopathy.

Retinol Dehydrogenase 10 Reduction Mediated Retinol Metabolism Disorder Promotes Diabetic Cardiomyopathy

Project description:Diabetic cardiomyopathy (DCM) is a primary myocardial injury induced by diabetes mellitus (DM) with a complex pathogenesis. In this study, we identified disordered cardiac retinol metabolism in T2DM mice and patients characterized by retinol (vitamin A, Rol) overload, all-trans retinoic acid (atRA) deficiency and retinoic acid receptors (RARs) reduction, and demonstrated that both cardiac Rol overload and atRA deficiency promote DCM by supplementing T2DM mice with Rol or atRA. Mechanically, by constructing cardiomyocyte-specific conditional RDH10-knockout mice and overexpressing RDH10 in T2DM mice via adeno-associated virus, we verified that the reduction in cardiac retinol dehydrogenase 10 (RDH10) is the initiating factor for cardiac retinol metabolism disorder and its resulting DCM. Additionally, lipotoxicity and ferroptosis contribute to the effect of retinol metabolism disorder on DCM. Based on these results, we suggest that the reduction of cardiac RDH10 and its mediated disorder of cardiac retinol metabolism is a new mechanism underlying DCM.

Title Page Cardiac Gene Therapy Rescues Diabetic Cardiomyopathy and Lowers Blood Glucose

Project description:Diabetic cardiomyopathy, an increasingly global epidemic and a major cause of heart failure with preserved ejection fraction (HFpEF), is associated with hyperglycemia, insulin resistance, and intra-cardiomyocyte calcium mishandling. Here we identify that, in db/db mice with type 2 diabetes induced HFpEF, abnormal remodeling of cardiomyocyte transverse-tubule microdomains occurs with downregulation of the membrane scaffolding protein cardiac bridging integrator 1 (cBIN1). Transduction of cBIN1 by AAV9 gene therapy can restore transverse-tubule microdomains to normalize intracellular distribution of calcium handling proteins and, surprisingly, glucose transporter 4 (GLUT4). Cardiac proteomics revealed that AAV9-cBIN1 normalizes components of calcium handling and GLUT4 translocation machineries. Functional studies further identified that AAV9-cBIN1 normalizes insulin-dependent glucose uptake in diabetic cardiomyocytes. Phenotypically, AAV9-cBIN1 rescues cardiac lusitropy, improves exercise intolerance, and ameliorates hyperglycemia in diabetic mice. Restoration of transverse-tubule microdomains can improve cardiac function in the setting of diabetic cardiomyopathy, and also improve systemic glycemic control.

Project description:Diabetic cardiomyopathy is a major health problem world wide. CTRP9 is a secreted glycoprotein, which is mainly expressed in endothelial cells of the heart. In this study, we investigated the impact of CTRP9 on diabetic cardiomyopathy induced by high fat diet feeding. While the lack of CTRP9 in knock-out mice aggravated the disease, AAV9 mediated cardiac CTRP9 overexpression ameliorated diastolic cardiac dysfunction under these conditions. Mechanistically, we found that CTRP9 is required for insulin dependent cardiac glucose uptake and metabolism and that it counteracts cardiac inflammation.

Differential analysis of mitochondria-associated reticulum membranes (MAMs) between standard diet-fed and high fat high sucrose diet fed mice

Project description:Type 2 diabetic cardiomyopathy (DCM) has been linked to Ca2+ signaling alterations, notably a decreased mitochondrial Ca2+ uptake. Uncovering of Ca2+ microdomains between cardiac mitochondria and reticulum launched a new investigation avenue for cardiometabolic diseases. We here aimed to study if the impairment of mitochondrial Ca2+ handling could be due to a dysregulation of the reticulum-mitochondria interactions or of the mitochondrial Ca2+ uniporter in the diabetic mice heart. Phenotypic alterations of the type 2 diabetic mouse heart, was done using an in vivo obesogenic high fat high sucrose diet fed mouse model (HFHSD: 20% proteins, 36% lipids). The composition of the cardiac MAM fractions between standard diet-fed (SD) mice and HFHSD (HF) mice at 16 weeks was analysed by MS-based quantitative proteomics.

Transcription profiling of rat ventricle samples from streptozotocin (STZ)-diabetic animals to investigate mitochondrial long-chain free fatty acid export

Project description:Cardiomyopathy in type 1 diabetic patients is characterized by early onset diastolic and late onset systolic dysfunction. The mechanism underlying development of diastolic and systolic dysfunction in diabetes remains unknown. We used microarrays to detail the ventricle gene expression changes that underly development of diabetic cardiomyopathy. We identified distinct classes of up-regulated genes during this process. Experiment Overall Design: 150g male Wistar rats (Harlan) we injected with 65 mg/kg streptozotocin to induce Type 1 diabetes. Four replicates of Control and Diabetic rat ventricles were removed and frozen at Three time points for total RNA isolation and hybridization on the Affymetrix RG-U34A microarray. The 3 day samples show a baseline for initial diabetic changes in the ventricle. The 28 day samples show changes associated with diastolic dysfunction in diabetes. The 42 day samples show changes associated with both diastolic and systolic dysfunction in type 1 diabetic rat ventricles.

Role of micro-RNAs in pathophysiology of diabetic cardiomyopathy.

Project description:Diabetic cardiomyopathy (DCM), occurs independent of Hypertension, Coronary artery disease, or any other known cardiac disease and is characterized by myocardial fibrosis, myocytes loss and hypertrophy. The molecular mechanisms leading to these diseased cardiac phenotype are still being elucidated. A small number of studies have demonstrated that altered expression of several microRNAs are associated with ischemia , mechanical overload, or cardiovascular biology; however, much work is still required to identify individual or group of microRNAs and their role in the pathophysiology of diabetic cardiomyopathy. The aim of present study was to identify the expression of individual or group of microRNAs associated with myocytes hypertrophy and myocardial fibrosis during DCM. MicroRNAs expression profiles were studied in myocardium from High Fat diet and streptozotocin (STZ) induced diabetic (n=4) and non-diabetic (n=2) Wistar rats. All normalized and filtered microRNAs (n=780) processed for differential expression study using unpaired T-test in Gene spring in which unpaired comparison has been performed as test vs. control. After unpaired T-test, total 72 microRNAs were found to be significantly expressed with P-value ≤0.05. Differentially expression analysis was performed and at fold Change cut off ≥ 1.0, all 780 microRNA passed and 39 out of 780 microRNAs were differentially expressed on fold Change cut-off ≥1.5. These results indicate that during the development and progression of DCM, various microRNAs were differentially expressed and may participate in the regulation of various signaling pathways leading to myocytes hypertrophy, apoptosis and cardiac fibrosis.

Monoamine oxidase-dependent pro-survival signaling in diabetic hearts [total RNA]

Project description:Diabetes leads to cardiomyopathy and heart failure, the leading cause of death for diabetic patients. Monoamine oxidase (MAO)-dependent reactive oxygen species (ROS) formation contributes to the development of diabetic cardiomyopathy by inducing mitochondrial and cardiomyocyte dysfunction. Yet, it is unclear whether, in addition to the direct effects exerted by MAO-dependent ROS on mitochondria, MAO activity is able to post-transcriptionally regulate cardiomyocyte function and survival in diabetes. To this aim, we performed gene and miRNA expression profiling in cardiac tissue from a mouse model of type 1 diabetes (T1D) with or without pharmacological MAO inhibition. We found that MAO-dependent ROS generation in T1D hearts leads to profound transcriptomic changes, affecting autophagy and pro-survival pathways activation. MAO activity in T1D hearts affected expression levels of miR-133a-3p, -193a-3p, and -27a-3p that target insulin-like growth factor receptor 1 (Igf1r), growth factor receptor bound protein 10 and inositol polyphosphate 4 phosphatase type 1A, respectively, all components of the Igf1r/PI3K/Akt signaling pathway. Indeed, Akt activation was significantly downregulated in T1D hearts, whereas MAO inhibition restored the activation of this pro-survival pathway. The present study provides an important link between MAO activity, transcriptomic changes, and activation of pro-survival signaling and autophagy in diabetic cardiomyopathy.
