Project description:Transgenic overexpression of Galgt2 in the skeletal muscles of mdx mice inhibits the development of disease pathology associated with muscular dystrophy. This is the case both in transgenic mice, where Galgt2 overexpression occurs from embryonic timepoints onward and in mdx mice where Galgt2 is overexpressed in the early postnatal period using Adeno-associated virus (AAV). Here, we use gene expression profiling to compare transcriptional changes resulting from embryonic and postnatal Galgt2 overexpression in mdx skeletal muscle. A surprising number of changes were in genes known to ameliorate muscular dystrophy when overexpressed (agrin, integrin alpha 7, ADAM12, Bcl2) or to cause muscular dystrophy when mutated (collagen VI (alpha1,alpha2), plectin 1, dystroglycan, selenoprotein N1, integrin alpha7, biglycan, dysferlin). Several genes involved in calcium homeostasis were also changed. In Galgt2 transgenic mice, where embryonic overexpression of Galgt2 in skeletal muscles alters neuromuscular development and muscle growth, the number of gene expression changes was vastly greater, however, 14% of genes altered in postnatal AAV-Galgt2 infected mdx muscles were also changed with embryonic overexpression. These experiments suggest that postnatal overexpression of Galgt2 inhibits muscular dystrophy in mdx mice via induction of a group of genes that, in aggregate, can govern membrane stability, membrane repair, calcium homeostasis, and apoptosis.

Experiment Overall Design: Microarrays were done in three groups at a time. 1) Transgenic Overexpression of Galgt2 - comprised to Wild Type (WT), Galgt2 Transgenic (CT), Dystrophin-Deficient (mdx), and Galgt2 Transgenic and Dystrophin-Deficient (CTmdx) each in duplicate 2) AAV-Mediated Galgt2 Gene Delivery in to the mdx gastrocnemius muscle in the postnatal period - comprised of AAVGalgt2 and PBS each in duplicate, and 3) Myoblasts and myotubes - comptised of one sample each of C1C12 myoblasts and myotubes, C2C12 myoblasts and myotubes stably transfected with Galgt2

Project description:Duchenne muscular dystrophy (DMD) is an X-linked recessive disease caused by deleterious mutations in the DMD gene, rendering non-functional forms or complete absence of the protein dystrophin. Eccentric contraction-induced force loss is the most robust and reproducible phenotype of dystrophin-deficient skeletal muscle, yet the molecular mechanisms underlying force loss remain obscure. To this end, we utilized the mdx mouse model of DMD, which displays extreme sensitivity to eccentric contractions. An existing mouse line from our lab that overexpresses cytoplasmic gamma-actin specifically in skeletal muscle (mdx/Actg1-TG) was shown to significantly protect mdx muscle against contraction-induced force loss. To understand the mechanism behind this protection, we performed iTRAQ proteomics on mdx/Actg1-TG tibialis anterior (TA) muscle versus non-transgenic littermate controls to identify differentially-expressed proteins that may afford protection upon gamma-actin overexpression.

Project description:Analysis of gene expression profile of Tibialis anterior (TA) skeletal muscle tissues with Notch1 intracellular domain (N1ICD) overexpression. Skeletal myogenesis involves sequential activation, proliferation, self-renewal/differentiation and fusion of myogenic stem cells (satellite cells). Notch signaling is known to be essential for the maintenance of satellite cells, but its function in late-stage myogenesis, i.e. post-differentiation myocytes and post-fusion myotubes, is unknown. Here we use muscle creatine kinase (MCK)-Cre to induce N1ICD expression in multinucleated myotubes. We found that myotube-specific Notch1 activation improved muscle regeneration and exercise performance of mdx mice, a model of Duchenne Muscular Dystrophy (DMD). Agilent microarray was performed to compare gene expression in mdx control and N1ICD-overexpressing mdx muscles. The results may provide mechanistic insights into how Notch1 activation in myotubes modulate muscle function.

Project description:CD4+Foxp3+ regulatory T cells (Tregs) accumulate in skeletal muscle from dystrophin-deficient mdx mice. Analysis of global gene expression in muscles from mdx mice treated with anti-CD25 compared with muscles from mdx mice treated with control antibody revealed that Tregs partially protect mdx mice from muscle pathology and promote muscle repair/regeneration.
