Gene expression data from DMD patient hiPSC-derived myoblasts treated with fenofibrate, ginsenoside Rd or DMSO

Project description:Drug development costs a significant amount of time and resources for new pharmaceutical drugs. However, the progress has been limited for orphan diseases such as Duchenne muscular dystrophy (DMD). By using human induced pluripotent stem cells (hiPSCs), here we show an exemplary drug screening campaign and the identification of two potential drugs effective in a DMD mouse model. We developed a DMD-hiPSC screening platform utilizing high-content imaging to identify hit compounds that enhance myogenic fusion abilities of patient-specific myoblasts. Among 1524 compounds (Johns Hopkins Clinical Compound library), two hit compounds restored in vitro fusion defects of DMD patient hiPSC-derived myoblasts. Transcriptional profiling revealed that the function of two hit compounds, ginsenoside Rd (natural product, ginseng extract) and fenofibrate (FDA-approved drug), are associated with FLT3 signaling and TGF-β signaling, respectively. The preclinical tests in mdx mice show that the treatment of the two hit compounds can ameliorate the skeletal muscle and behavioral phenotypes caused by DYSTROPHIN deficiency, suggesting therapeutic potential of these two compounds. Our study demonstrates the feasibility of early-stage drug development for rare diseases using symptom-relevant cells derived from patient-specific hiPSCs.

Correction of the exon 2 duplication in DMD myoblasts by a single CRISPR/Cas9 system

Project description:Exonic duplications account for 10-15% of all mutations in Duchenne muscular dystrophy (DMD), a severe hereditary neuromuscular disorder. We report a novel CRISPR (Clustered Regularly Interspaced Short Palindromic Repeat)/Cas9-based strategy to correct the most frequent (exon 2) duplication in the DMD gene by targeted deletion, and tested the efficacy of such an approach in patient-derived myogenic cells. We demonstrate restoration of wild-type dystrophin expression at transcriptional and protein level in myotubes derived from genome-edited myoblasts in the absence of selection. Removal of the duplicated exon was achieved by the use of only one gRNA directed against an intronic duplicated region, thereby increasing editing efficiency and reducing the risk of off-target effects. This study opens a novel therapeutic perspective for patients carrying disease-causing duplications independently from the duplication extension.

Loss of full-length dystrophin expression causes major cell-autonomous abnormalities in proliferating myoblasts

Project description:Duchenne muscular dystrophy (DMD) is a severely debilitating and incurable neuromuscular disease. Its conspicuous feature is the absence of dystrophin in myofibers and therefore most therapeutic approaches focus on some form of its re-expression there. However, increasing body of evidence points at an early developmental onset of DMD and severe abnormalities were uncovered in dystrophic muscle stem cells. In this study, we explore gene expression changes in primary myoblasts from mice lacking expression of the full length dystrophin transcript. Total RNA extracted from primary myoblasts isolated from gastrocnemii of 8 week old male Dmd-mdx (MDX - lacking the full length dystrophin transcript), Dmd-mdx-βgeo (BGEO - lacking all dystrophin expression) and control mice (WT) were subjected to RNA sequencing following ribodepletion, and analysed for the differential expression of genes between groups and the enrichment of gene ontology categories or pathways.

The effect of fenofibrate on endothelial cells

Outer membrane vesicle and outer membrane of Haemophilus influenzae Rd KW20, Rd ∆yrbE and Rd ∆vacJ

Project description:Bacterial outer membrane vesicles (OMVs) have important biological roles in pathogenesis and intercellular interactions, but a general mechanism of OMV formation is lacking. Here we show that the VacJ/Yrb ABC transport system, a proposed phospholipid (PL) transporter, is involved in OMV formation. Deletion or repression of VacJ/Yrb increases OMV production in two distantly related Gram-negative bacteria, Haemophilus influenzae and Vibrio cholerae. Within our studies we also analyzed the proteome of the OMV and outer membrane (OM) and found no massive alteration in Haemophilus influenzae Rd KW20, Rd ∆yrbE and Rd ∆vacJ. Lipidome analyses demonstrate that OMVs from VacJ/Yrb-defective mutants in H. influenzae are enriched in PLs and certain fatty acids. Furthermore, we demonstrate that OMV production and regulation of the VacJ/Yrb ABC transport system respond to iron starvation. Our results suggest a new general mechanism of OMV biogenesis based on PL accumulation in the outer leaflet of the outer membrane. This mechanism is highly conserved among Gram-negative bacteria, provides a means for regulation, can account for OMV formation under all growth conditions, and might have important pathophysiological roles in vivo.

The effect of fenofibrate on endothelial cells

Project description:Fenofibrate is a synthetic ligand for the nuclear receptor peroxisome proliferator-activated receptor (PPAR) alpha, but there are reports that fenofibrate affects endothelial cells in PPARa-independent manner. In order to identify PPARa-dependently and PPARa-independently regulated transcripts we generated microarray data from human endothelial cells treated with fenofibrate with and without siRNA-mediated knock-down of PPARa. In this study, we generated microarray data from human umbilical vein endothelial cells (HUVECs) treated with fenofibrate. Time 0 indicates the start point of observation immediately prior to exposure to the 25umol fenofibrate. There are five time points (2, 4, 6, 8, and 18hours) (n=3 at each time point). The control is untreatment HUVEC (n=4).
