RNAi Screening for Ubiquitin Ligases that Regulate Myofiber Size Identifies a Key Role for UBR4 in Myofiber Hypertrophy in Drosophila and Mice

ABSTRACT: Sequencing of RNA isolated from the tibialis anterior muscles of 6 month old C57BL/6J mice that had been injected and electroporated with either a control non-targeting siRNA (NT) or two different UBR4 targeting siRNA sequences (UBR4 siRNA5 and siRNA7) to deplete UBR4. Muscles were harvested 7 days after electroporation and showed significant loss of UBR4 coincident with hypertrophy of type 2A and 2X myofibers.

Nr2f6 electroporation in tibialis anterior promotes muscle weakness

Project description:Mouse tibialis anterior muscles were electroporated with Nr2f6-myc plasmid or pCMV6 empty vector in the contralateral leg. After 9 days, muscles were collected, and the RNA extracted and processed for microarray analysis.

Depletion of Erk1 and Erk2 MAP kinases in primary human keratinocytes

Project description:We assessed the effect of RNAi-mediated MAP kinase cascade signaling blockade in primary human keratinocytes. Two sets of siRNA targeting different regions of the Erk1/2 genes were used, enabling identification of off-target siRNA effects. Primary human keratinocytes were electroporated with scrambled control siRNA, a pair of siRNA oligomers against Erk1 and Erk2 (set A), or an independent pair of siRNA oligomers against Erk1 and Erk2 (set B). Four days after electroporation, RNA was harvested. Three biological replicates were performed for each of the three siRNA groups.

Dystrophic single myofibers vs. control single myofibers

Project description:MicroRNA-expression profile of dystrophic single fibers compared to wild type single fibers isolated from different muscles of mdx and C57BL mice. Myofibers were isolated from different muscle types (tibialis, diaphragm and quadriceps) of gender- (male) and age- (3 month old and half) matched wt and dystrophic mice. 9 total samples per animal model (C57BL, mdx), 3 replicates per muscle type.

Effect of a myofiber-specific HIRA conditional knockout on gene expression in mouse skeletal muscle at 6 months of age

Project description:We performed gene expression profiling by microarray using RNA extracted from the tibialis anterior of control and Hira myofiber-specific conditional knockout mice at 6 months of age. Hira is a histone chaperone responsible for replication-independent incorporation of histone variant H3.3 at actively transcribed loci. Conditional knockout of Hira in myofibers improved strength and endurance, caused hypertrophy and regeneration, and increased the percentage of type I fibers. These results illustrate the physiological consequences of disrupting Hira-mediated chromatin assembly in myofibers.

Pabpn1-driven cytoskeletal rearrangement induces muscle wasting

Project description:Poly(A) binding protein nuclear 1 (PABPN1) is a multifunctional regulator of mRNA processing. PABPN1 inhibits alternative polyadenylation (APA), and in conditions with reduced PABPN1 levels APA utilization causes genome-wide mRNA dysregulation. PABPN1 levels decline from midlife onwards in Oculopharyngeal Muscular Dystrophy (OPMD) and in aged muscles. Reduced PABPN1 levels cause muscle atrophy by altering mRNA levels of the ubiquitin proteasome system. The effect of PABPN1-mediated APA utilization on the proteome has not been investigated yet. We report the PABPN1-mediated proteome in Tibialis anterior (TA) mouse muscles, signifying functional impact for the mitochondria, cytoskeleton and translation cellular machineries. Central nucleation and split myofibers marked PABPN1-derived muscle histology. We show that up-regulation of the cytoskeletal proteins: Murc, Pfn1 and Csrp3, is highly associated with PABPN1-mediated muscle pathology and with reduced PABPN1 levels. Elevation of PABPN1 levels by sirtinol treatment reversed muscle pathology and restored levels of those cytoskeletal proteins. We suggest that restoration of PABPN1 levels in aged muscles could be a novel therapeutic strategy to mitigate muscle waste.
