Project description:The first GSSM of V. vinifera was reconstructed (MODEL2408120001). Tissue-specific models for stem, leaf, and berry of the Cabernet Sauvignon cultivar were generated from the original model, through the integration of RNA-Seq data. These models have been merged into diel multi-tissue models to study the interactions between tissues at light and dark phases.
Project description:Analysis of the function of miR-1/133a clusters in Physiology of the adult heart. Analysis of transcriptome was perfromed for heart tissue isolated from WT (n=7), miR-1-1/133a KO (mouse chromosome 2; n=4) and miR-1-2/133a-1 KO (mouse chromosome 18; n=5) animals.
Project description:To identify the potential microRNAs (miRNAs) involved in the regulation of cardiomyocyte (CM) proliferation during homeostasis and injury, RNA sequencing (RNA-seq) in mouse cardiac ventricles was performed on postnatal day 1, 7, and 28 (P1, P7, and P28). Significant upregulation of MiR-128 was found in P7 hearts as compared to P1. To further specify the effect of miR-128 in the heart, RNA-Seq was performed in control mice (Ctrl) and miR-128 overexpression mice (miR-128OE) on P7. These data provide novel insights into the mechanisms by which adult CMs exit the cell cycle arrest and is fundamental for therapeutic manipulation to stimulate endogenous CM proliferate in cardiac regeneration.
Project description:In the current study we examined several proteomic- and RNA-Seq-based datasets of cardiac-enriched, cell-surface and membrane-associated proteins in human fetal and mouse neonatal ventricular cardiomyocytes. By integrating available microarray and tissue expression profiles along with MGI phenotypic analysis, we identified 173 membrane-associated proteins that are cardiac-enriched, conserved amongst eukaryotic species, and have not yet been linked to a ‘cardiac’ Phenotype-Ontology. To highlight the utility of this dataset, we selected several proteins to investigate more carefully, including FAM162A, MCT1, and COX20, to show cardiac enrichment, subcellular distribution and expression patterns in disease. Three-dimensional imaging was used to validate subcellular localization and expression in adult mouse ventricular cardiomyocytes. FAM162A, MCT1, and COX20 were differentially expressed at the transcriptomic and proteomic levels in multiple models of mouse and human heart diseases and may represent potential diagnostic and therapeutic targets for human dilated and ischemic cardiomyopathies. Altogether, we believe this comprehensive cardiomyocyte membrane proteome dataset will prove instrumental to future investigations aimed at characterizing heart disease markers and/or therapeutic targets for heart failure.
Project description:To explore the role of miR-22 targeting in different tissues in adult mice, we generated a miR-22 null mouse model and profiled expression in muscle, heart, liver, kidney and white adipose tissue.
