Project description:Soleus muscle has the most abundant H19 expression compared to other skeletal muscle tissues. In order to identify genes regulated by long noncoding RNA H19 in skeletal muscle, we performed RNA-Seq with dissected WT and H19KO soleus muscles from 21 week old mice. Among the differentially expressed genes, we found skeletal muscle - overexpressed gene DUSP27, which potentially plays an important role in regulating skeletal muscle glucose metabolisim by regulating the activitiy of AMPK, might be a target of H19 mediated regulation.

Project description:Dystrophin proteomic regulation in Muscular Dystrophies (MD) remains unclear. We report that a long noncoding RNA (lncRNA) H19 associates with dystrophin. To investigate the biological roles of this interaction in vivo, we performed mass spectrometry analysis of dystrophin and its associated proteins in H19-proficient and -deficient C2C12 myotubes. Mass spectrometry data indicated that in H19-proficient myotubes, dystrophin associates with components of dystrophin-associated protein complex (DPC); however, in H19-deficient myotubes, dystrophin associated with UBA1, UB2G1, TRIM63 ubiquitin E3 ligase and ubiquitin. In H19-deficient myotubes, dystrophin was post-translationally modified with K48-linked poly-ubiquitination at Lys3577 (referred to as Ub-DMD). This mass spectrometry study demonstrated that lncRNA H19, associates with dystrophin and inhibits E3 ligase-dependent Ub-DMD formation and its subsequent proteasomal degradation. Based on this study, H19 RNA oligonucleotides conjugated with a muscle homing ligand Agrin (referred to as AGR-H19) and Nifenazone, a TRIM63-specific small molecule inhibitor, reverses the dystrophin degradation in iPSC-derived skeletal muscle cells from Becker Muscular Dystrophy patients. Furthermore,treatment of mdx mice with exon-skipping reagent, in combination with either AGR-H19 or Nifenazone, dramatically stablized dystrophin, preserved skeletal/cardiac muscle histology, and improved strength/heart function. In summary, this mass spectrometry study paves the way to meaningful targeted therapeutics for BMD and certain DMD patients.

Project description:We analyzed the functional role of DOR (Diabetes and Obesity Regulated gene) (also named Tp53inp2) in skeletal muscle. We show that DOR has a direct impact on skeletal muscle mass in vivo. Thus, using different transgenic mouse models, we demonstrate that while muscle-specific DOR gain-of-function results in reduced muscle mass, loss-of-function causes muscle hypertrophy. DOR has been described as a protein with two different functions, i.e., a nuclear coactivator and an autophagy regulator (Baumgartner et. al., PLoS One, 2007; Francis et. al., Curr Biol, 2010; Mauvezin et. al., EMBO Rep, 2010; Nowak et. al., Mol Biol Cell, 2009). This is why we decided to analyze which of these two functions could explain the phenotype observed in our mice models. In this regard, we performed a transcriptomic analysis using microarrays looking for genes differentially expressed in the quadriceps muscle of WT and SKM-Tg mice as well as in C and SKM-KO animals. Surprisingly, only a reduced number of genes were dysregulated upon DOR manipulation and most of the genes underwent mild changes in expression. These data strongly suggest that DOR does not operate as a nuclear co-factor in mouse skeletal muscle under the conditions subjected to study. In contrast, DOR enhances basal autophagy in skeletal muscle and promotes muscle wasting when autophagy is a contributor to muscle loss. To determine the functional role of DOR in skeletal muscle, we generated transgenic mice (SKM-Tg) overexpressing DOR specifically in skeletal muscle under the Myosin-Light Chain 1 promoter/enhancer. The open reading frame of DOR was introduced in an EcoRI site in the MDAF2 vector, which contains a 1.5 kb fragment of the MLC1 promoter and 0.9 kb fragment of the MLC1/3 gene containing a 3' muscle enhancer element (Rosenthal et. al., PNAS, 1989; Otaegui et. al., FASEB J, 2003). The fragment obtained after the digestion of this construct with BssHII was the one used to generate both transgenic mouse lines. Nontransgenic littermates were used as controls for the transgenic animals (Wt). In addition, a muscle-specific DOR knock-out mouse line (SKM-KO) was also generated by crossing homozygous DOR loxP/loxP mice with a mouse strain expressing Cre recombinase under the control of the Myosin-Light Chain 1 promoter (Bothe et. al., Genesis, 2000). Deletion of exons 3 and 4 driven by Cre recombinase caused the ablation of DOR expression. Non-expressing Cre DOR loxP/loxP littermates were used as controls for knockout animals (C). Four-month-old male mice were used in all experiments. Mice were in a C57BL/6J pure genetic background.
