Identification of differentially expressed genes and pathways for myofiber characteristics in soleus and extensor digitorum longus muscles between chicken breeds differing in meat quality

ABSTRACT: In the modern chicken industry, fast-growing broilers have undergone strong artificial selection for muscle growth, which has led to remarkable phenotypic variations compared with slow-growing chickens. However, the molecular mechanism underlying these phenotypes differences remains unknown. In this study, a systematic identification of candidate genes and new pathways related to myofiber development and composition in chicken Soleus muscle has been made using gene expression profiles of two distinct breeds: Qingyuan partridge (QY), a slow-growing Chinese breed possessing high meat quality and Cobb 500 (CB), a commercial fast-growing broiler line. Agilent cDNA microarray analyses were conducted to determine gene expression profiles of soleus and extensor digitorum longus muscle sampled at sexual maturity age of QY (112 d) and CB (42 d).

Differences in gene expression between fast and slow muscle or between normal and denervated slow muscles

Differences in gene expression between fast and slow muscle or between normal and denervated slow muscles

Project description:Fast and slow skeletal muscles show different characteristics and phenotypes. This data obtained from microarray includes the comparison of normal fast plantaris and slow soleus muscles of adult rats. Characters of slow muscle are strongly dependent on the level of muscular activity. Denervation silences the muscular activity. Therefore, we determined the effects of denervation on gene expression in slow soleus muscle of adult rats. Denervation was performed by transection (~5 mm) of left sciatic nerve at the gluteal level. No treatments were made in the normal control rats. Sampling of soleus and/or plantaris was performed in both normal and experimental groups 28 days after the surgery.

Fold change of expression in Aseel (an indigenous chicken breed) as compared to broiler chicken in muscle of 18th day of embryonic stage

Project description:The expression of genes were analysed in muscle of 18th day of embryonic stage between Aseel, an indigenous slow-growing chicken, and control broiler, a fast-growing broiler chicken line. The whole embryo was collected in TRIZOL and total RNA was isolated. The expression profile of gene was determined in 64k Agilent chicken microarray chip. The Cy3 dye was used for detection. The fold change of expression was analysed in Aseel as compared to broiler chicken line.

The MuSK-BMP pathway maintains myofiber size in slow muscle through regulation of Akt-mTOR signaling

Project description:Myofiber size regulation is critical in health, disease, and aging. MuSK (muscle-specific kinase) is a BMP (bone morphogenetic protein) co-receptor that promotes and shapes BMP signaling that is expressed at all neuromuscular junctions and is also present extrasynaptically in the slow soleus muscle. To investigate the role of the MuSK-BMP pathway in vivo we generated mice lacking the BMP-binding MuSK Ig3 domain. These ∆Ig3-MuSK mice are viable and fertile with innervation levels comparable to wild type. In 3-month-old mice myofibers are smaller in the slow soleus, but not in the fast TA. Here we use bulk RNA-seq to perform transcriptomic analysis of slow and fast mouse muscle. RNAseq analysis revealed soleus-selective decreases in RNA metabolism and protein synthesis pathways as well as dysregulation of IGF1 pathway components. Moreover, Akt-mTOR signaling is reduced in soleus but not TA. We propose that the MuSK-BMP pathway acts extrasynaptically to maintain myofiber size in slow muscle by promoting protein synthetic pathways including the IGF1-Akt-mTOR signaling. These results reveal a novel mechanism for regulating myofiber size in slow muscle and introduce the MuSK-BMP pathway as a target for promoting muscle growth and combatting atrophy.

Effect of deletion of ERRalpha, ERRbeta and/or ERRgamma on gene expression in soleus and extensor digitorum longus (EDL) skeletal muscles

Project description:The three estrogen related receptors (ERRs) are regulators of oxidative metabolism in many cell types, yet their roles in skeletal muscle have not been elucidated. To address the roles and significance of ERRs for skeletal muscle mitochondria and muscle function, we generated mice lacking combinations of ERRs specifically in skeletal muscle. We then compared the impact of ERR loss on the transcriptomes of EDL and soleus, i.e., muscles rich in glycolytic or oxidative fibers, respectively. Our findings highlight an essential role of ERRs for skeletal muscle oxidative metabolism and identify broad classes of ERR-dependent gene programs in muscle. They also suggest a high degree of functional redundancy among muscle ERR isoforms for the protection of oxidative capacity, with ERR isoform-specific phenotypes being driven primarily, but not exclusively, by their relative levels in different muscles. To compare the relative contributions of ERRs for oxidative capacity in glycolytic and oxidative skeletal muscles, we generated mice lacking one or two ERRs specifically in skeletal muscle. We then performed gene expression profiling analysis using data obtained from RNA-seq of soleus and EDL muscles of WT and ERR KO mice .

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.
