Project description:RNA-seq was performed to compare expression pattern of musles taken form two mice strains- mdx and mdx/Runx1f/f, which are double KO carrting a muscle specific ablation of Runx1 using a Myf5-Cre. This comparison revealed the Runx1- responsive gene set in mdx muscles. we could cross this data with prior retrived datd from privous experiments found in this GEO quary, to pinpiont Runx1 target genes in muscle rgeneration

Project description:Quadriceps muscles were harvested from 20-week-old male wild-type, mdx, and mdx TG mice expressing hSSPN and snap frozen in liquid nitrogen. Samples were then prepared for mass spectrometry analysis using a 3 fraction method (cell, soluble ECM and insoluble ECM).

Project description:We found genetic deletion of IKKβ in mdx cardiomyocytes improved cardiac function and normalized calcium transients. We used microarrays to profile gene expression in hearts of mdx mice with intact IKKβ signaling and hearts of mdx mice with IKKβ-deficient cardiomyocytes to identify genes differentially regulated by NF-[kappa]B. signaling in dystrophic hearts.

Project description:The mdx mouse (C57BL/10ScSn-DMDmdx/J), like Duchenne muscular dystrophy (DMD) patients, lacks the protein dystrophin. However, the mdx mouse has a normal lifespan and mild pathology while DMD remains a severe, fatal disease. New mouse models have been developed that are more severely affected but they have not replaced the mdx mouse in DMD research. A few years ago RNA-sequencing (RNA-seq) results of biopsies from DMD and normal human muscle were published but we could not find equivalent data for the mouse. We now report RNA-sequencing of three wild-type and mdx mouse muscles: the flexor digitorum brevis (FDB), the extensor digitorum longus (EDL), and the soleus (SOL). The FDB, a plantar foot muscle is often used for in vivo and ex vivo experiments but may be less affected by the lack of dystrophy than the hindlimb muscles. We compared muscles from 2- and 5-month old mice to investigate the time-course of the mdx pathology. The results show a muscle- and age-dependent parallel between mdx and DMD muscles. Although the FDB is less affected than EDL and SOL at 2 months, the three muscles show, at both ages, activation of close to 100 genes from 7 pathways that are affected in presymptomatic DMD patients and have been called "DMD disease signature".

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.
