Differential miRNA expression of inherently high- and low-active inbred mice

ABSTRACT: To further our understanding of the biological mechanisms regulating voluntary physical activity levels, we measured differential miRNA expression in two strains of mice that have been repeatedly shown to have inherently high and low voluntary physical activity levels measured by wheel running. RNA from skeletal muscle (soleus and extensor digitorum longus (EDL)) and nucleus accumbens in the brain tissues were evaluated by microarray. There were no other variables besides inherent strain differences. Thirteen miRNAs from nucleus accumbens, 22 from soleus, and nine miRNAs from EDL were determined to be differentially expressed by microarray analysis. RT-qPCR validated mir-342b-3p and 466d-3p to be differentially expressed in the NA, and miR-466b-3p in the soleus.

Comparative Transcriptome Analysis between SOL and EDL Muscle in Yorkshire pigs using Affymetrix microarray

Project description:Skeletal muscle is heterogeneous in nature and distinguished as red muscle and white muscle because of their myofiber composition. Soleus (SOL) is a typical red muscle and extensor digitorum longus (EDL) is a typical white muscle. In this study, we compared the transcriptome difference of soleus and extensor digitorum longus from three 10-week-old Yorkshire boars with porcine Affymetrix microarray.

Expression data from skeletal muscles of Ts1Cje and disomic C57BL/6 mice

Project description:To determine the gene expression profile of extensor digitorum longus (EDL) and soleus (SO) muscles of wild-type and Ts1Cje mouse model of Down Syndrome (DS). Two types of skeletal muscles (EDL and SO) were harvested from both Ts1Cje and its disomic littermate.

miRNA expression in fast and slow skeletal muscle of wild type and SOD1-G93A mice

Project description:Amyotrophic lateral sclerosis (ALS) is a lethal motor neuron disease that progressively debilitates neuronal cells that control voluntary muscle activity. In a mouse model of ALS that expresses mutated human superoxide dismutase 1 (SOD1-G93A) skeletal muscle is one of the tissues affected early by mutant SOD1 toxicity. Fast-twitch and slow-twitch muscles are differentially affected in ALS patients and in the SOD1-G93A model, fast-twitch muscles being more vulnerable. We used miRNA microarrays to investigate miRNA alterations in fast-twitch (EDL) and slow-twitch (soleus) skeletal muscles of symptomatic SOD1-G93A animals and their age-matched wild type littermates. At age of 90 days RNA was extracted from extensor digitorum longus (EDL) and soleus (SOL) muscles of male SOD1-G93A animals and their age-matched wild type male littermates. RNA was hybridized on Affymetrix Multispecies miRNA-2_0 Array.

Subcellular localization analysis of long non-non coding RNAs (lncRNAs) in skeletal muscle myofibers

Project description:In order to study the subcellular localization of lncRNAs in myofibers of skeletal muscle, single myofibers were isolated from Soleus, Extensor Digitorum Longus (EDL) and Tibialis Anterior (TA) of 9 mice. RNA was extracted from nuclei and cytoplasmic fractions of 5-10 isolated myofibers and than separately hybridized on microarrays. Preferential expression in nuclear or cytoplasmic compartment of each lncRNA was determined.

Global gene expression analysis highlights microgravity sensitive key genes in soleus and EDL of 30 days space flown mice

Project description:Microgravity exposure as well as chronic muscle disuse are two of the main causes of physiological adaptive skeletal muscle atrophy in humans and murine animals in physiological condition. The aim of this study was to investigate, at both morphological and global gene expression level, skeletal muscle adaptation to microgravity in mouse soleus and extensor digitorum longus (EDL). Adult male mice C57BL/N6 were flown aboard the BION-M1 biosatellite for 30 days on orbit (BF) or housed in a replicate flight habitat on Earth (BG) as reference flight control. In this study, we investigated for the first time gene expression adaptation to 30 days of microgravity exposure in mouse soleus and EDL, highlighting potential new targets for improvement of countermeasures able to ameliorate or even prevent microgravity-induced atrophy in future spaceflights.

Skeletal muscle myonuclei-specific ChIP-Seq of H3K4me3 and H3K27ac

Project description:Skeletal muscle is a heterogeneous tissue. To study the myo-specific epigenetic landscape in the slow soleus and fast extensor digitorum longus (EDL) muscle, myonuclei were purified with PCM1 -an endogenous mark specific for mature myonuclei. Chromatin immunoprecipitation sequencing (ChIP-Seq) was performed using antibodies against the histone marks H3K4me3 and H3K27ac. Comparison of the differently enriched areas between the two muscles shows that the epigenetic landscape reflects the functional properties of the muscles, each with a distinct regulatory program involving distal regulatory enhancers.
