Project description:To explore the unique pathogenesis of DCM and analyzed the differences in gene expression, associated pathways and immune cell infiltration among different organs that are targeted by high glucose by bioinformatics-based strategy. In order to find the specific factors that trigger DCM, we contrasted the gene profile of DCM to that of other diabetic diseases including diabetic peripheral neuropathy (DPN) and nephropathy (DN). we performed RNA-seq and miRNA sequencing on heart tissue from db/db mice to explore the transcriptome alterations in DCM pathogenesis including lncRNA, miRNA and mRNA.

Project description:Diabetic cardiomyopathy (DCM), a common complication of diabetes, is defined as ventricular dysfunction in the absence of underlying heart disease. Noncoding RNAs (ncRNAs), including long noncoding RNAs (lncRNAs) and microRNAs (miRNAs), play a crucial role in the development of DCM. Weighted Gene Co-Expression Network Analysis (WGCNA) was used to identify key modules in DCM-related pathways. DCM-related miRNA-mRNA network and DCM-related ceRNA network were constructed by miRNA-seq to identify hub genes in these modules. We identified five hub genes that are associated with the onset of DCM, including Troponin C1 (Tnnc1), Phospholamban (Pln), Fatty acid binding proteins 3 (Fabp3), Popeye domain containing 2 (Popdc2), and Tripartite Motif-containing Protein 63 (Trim63). miRNAs that target the hub genes were mainly involved in TGF-β and Wnt signaling pathways. GO BP enrichment analysis found these miRNAs were involved in the signaling of TGF-β and glucose homeostasis. Q-PCR results found the gene expressions of Pln, Fabp3, Trim63, Tnnc1, and Popdc2 were significantly increased in DCM. Our study identified five hub genes (Tnnc1, Pln, Fabp3, Popdc2, Trim63) whose associated ceRNA networks are responsible for the onset of DCM.

Project description:Diabetic cardiomyopathy (DCM) is a specific form of cardiomyopathy that is independent of coronary artery disease and hypertension. Exploring the transcriptomics and proteomics of DCM is of great significance for understanding the biology of the disease and for guiding new therapeutic targets for the potential therapeutic effect of spermine (SPM).

Project description:Diabetes is associated with cardiovascular complications. microRNAs translocate into subcellular organelles to modify genes involved in diabetic cardiomyopathy. However, functional properties of subcellular Ago2, a core microRNA, remain elusive. We elucidated the function and mechanism of subcellular localized Ago2 on mouse models for diabetes mellitus and diabetic cardiomyopathy. Ago2 decreased in cardiomyocyte mitochondria in both models. Overexpression of mitochondrial Ago2 attenuated diabetes-induced cardiac dysfunction. Ago2 recruited TUFM, a mitochondria translation elongation factor, to activate translation of electron transport chain (ETC) subunits and decrease reactive oxygen species. Malonylation, a post-translational modification of Ago2, reduced the importing of Ago2 into mitochondria in diabetic cardiomyopathy. Ago2 malonylation was regulated by a cytoplasmic-localized short isoform of SIRT3 through a previously unknown demalonylase function. Our results reveal that the SIRT3–Ago2–CYTB axis links glucotoxicity to cardiac ETC imbalance, providing new mechanistic insights and the basis to develop mitochondria targeting therapies for diabetic cardiomyopathy.
