Project description:Myocardial infarction (MI) is a highly prevalent cardiac emergency, which results in adverse left ventricular remodeling exacerbating progressive heart failure. Inflammation in post-MI is necessary for myocyte repair and wound healing. However, it is also a key component of subsequent heart failure pathology. Myoblasts transplantation after MI have been fulfilled a good effect on cardiac repair, but the occasion, complications of transplantation, and the underlying mechanisms have not been fully elucidated. Here, we found that myoblast transplantation decreased the expression of many pro-inflammatory genes and the activation of inflammation-related signal pathway in heart tissue of pig post MI, which mainly contributed to the improved heart function and attenuated damage of myocardial cells.

Project description:Ischemia, fibrosis, and remodeling lead to heart failure after severe myocardial infarction (MI). Myoblast sheet transplantation is a promising therapy to enhance cardiac function and induce therapeutic angiogenesis via a paracrine mechanism in this detrimental disease. We hypothesized that in a rat model of MI-induced chronic heart failure this therapy could further be improved by overexpression of the antiapoptotic, antifibrotic, and proangiogenic hepatocyte growth factor (HGF) in the myoblast sheets. We studied the ability of wild type (L6-WT) and human HGF-expressing (L6-HGF) L6 myoblast sheet-derived paracrine factors to stimulate cardiomyocyte, endothelial cell, or smooth muscle cell migration in culture. Further, we studied the autocrine effect of hHGF-expression on myoblast gene expression using microarray analysis. We induced MI in Wistar rats by left anterior descending coronary artery (LAD) ligation and allowed heart failure to develop for four weeks. Thereafter, we administered L6-WT (n=15) or L6-HGF (n=16) myoblast sheet therapy. Control rats (n=13) underwent LAD ligation and rethoracotomy without therapy and five rats underwent sham-operation in both surgeries. We evaluated cardiac function with echocardiography at 2 and 4 weeks after therapy administration. We analyzed cardiac angiogenesis and left ventricular architecture from histological sections 4 weeks after therapy. Paracrine mediators from L6-HGF myoblast sheets effectively induced migration of cardiac endothelial and smooth muscle cells but not cardiomyocytes. Microarray data revealed that hHGF-expression modulated myoblast gene expression. In vivo, L6-HGF sheet therapy effectively stimulated angiogenesis in the infarcted and non-infarcted areas. Both L6-WT and L6-HGF therapies enhanced cardiac function and inhibited remodeling in a similar fashion. In conclusion, L6-HGF therapy effectively induced angiogenesis in the chronically failing heart. Cardiac function, however, was not further enhanced by hHGF-expression. Analysis of the L6 rat skeletal myoblast cell line and myoblast cell sheets with constitutive human HGF expression.

Project description:Long non-coding RNAs (lncRNAs) play important roles in diverse biological processes. However, the landscape of lncRNAs is largely unclear in Sus scrofa. Here we performed stranded RNA-seq on total RNA libraries from over 100 samples of Sus scrofa tissues. We identified 10,813 lncRNAs in Sus scrofa, of which 9,075 are novel. 57% of these lncRNAs were conserved in both human and mouse. These conserved lncRNAs tend to be more tissue-specific than pig-specific lncRNAs, and enriched in reproducible organs (i.e. testis and ovary). We characterized a group of lncRNAs potentially involved in the skeletal muscle development. One such lncRNA, a homolog of maternally expressed gene 3 (MEG3), was specifically expressed in the skeletal muscle at early developmental stage. And its expression pattern is conserved in pig and mouse. By over-expressing and knocking down MEG3 in mouse myoblast cell lines, we demonstrated its novel function as a myoblast proliferation suppressor.

Project description:Affymetrix microarray analysis of molecular changes after myocardial infarction. Samples of heart tissue were analyzed after myocardial infarction from WT and reg3beta knock-out mice. Samples from scar tissue and samples adjacent to the scar were analyzed. In the experiment we primarily compared infarction zone of wild-type to infarction zone of knock-out animals, and remote zone of wild-type to remote zone of knock-outs.
