Differentially modulated transcriptomes of mouse skeletal muscle (gastrocnemius) during postnatal development

Project description:Purpose: During postnatal development the fetal skeletal muscle undergoes a rapid and dramatic transition to adult function through transcriptional and post-transcriptional mechanisms, including alternative splicing (AS) Methods:We performed RNA-seq for high-resolution analysis of transcriptome changes during postnatal mouse skeletal muscle development using RNA from gastrocnemius muscle from embryonic day 18.5, postnatal day 2 (PN2), PN14, PN28, adult (22 weeks). Results: We identified a novel role for AS in several cellular functions including calcium handling and membrane organization during postnatal skeletal muscle development. Furthermore, AS transitions within calcium handling genes are responsive to Celf1 and Mbnl1, RNA-binding proteins with developmentally regulated expression. Conclusions: We identified a novel role for AS in several functional categories during postnatal development including calcium handling, vesicular trafficking and cell junctions.

Identification of differentially expressed genes in fetal and postnatal pig skeletal muscle

Project description:Fetal myogenesis and postnatal skeletal muscle hypertrophy in growing pigs are critical yet poorly understood processes. Global gene expression analyses will increase understanding of these processes by identifying key genes and pathways controlling skeletal muscle development. For this study, a pig 70-mer oligonucleotide microarray was used to identify differentially expressed genes in hind limb skeletal muscle of pigs at 60 days of gestation and 7 weeks of age. This oligonucleotide microarray experiment revealed 162 genes that were differentially expressed between 60 day fetal and 7 week postnatal samples. Relative real-time RT-PCR was used to confirm differential expression of three genes. This experiment identified genes exhibiting different developmental patterns of gene expression in pig skeletal muscle. Oligonucleotide microarrays used for this study consisted of 13,297 70-mer oligos (Pig Array-Ready Oligo Set v. 1.0 and Pig Oligo Extension Set v. 1.0, Qiagen, Inc., Valencia, CA) each spotted once on a single slide . Controls included 76 Arabidopsis thaliana gene spots, 17 beta tubulin spots, 17 glyceraldehyde-3-phosphate dehydrogenase spots, 85 heat shock protein gene spots, 69 ribosomal protein gene spots, 112 randomly generated negative control spots and 470 blanks. The oligonucleotide microarray was screened with samples obtained from pigs at 60 days of gestation and 7 weeks of age postnatal (n = 3 per age). Six oligonucleotide microarray slides were screened. All samples were used twice, labeled once with Cy3 and once with Cy5, and each 60 day gestation sample was randomly paired with two different 7 week postnatal samples.

Analysis of gastrocnemius muscle from chow-fed control and skeletal muscle specific Cpt1b knockout mice

Project description:To determine the transcriptomic effects of Cpt1b loss on skeletal muscle gene expression, we assessed gastrocnemius muscle in chow-fed control and Cpt1b skeletal muscle specific knockout mice using a serial analysis of gene expression strategy. Complementary bioinformatics pathway enrichment studies were performed which indicated that differentially expressed genes between genotypes were predominantly related to various processes include carbohydrate metabolism, lipid metabolism, amino acid metabolism, cell proliferation, and apoptosis.

Study of the signaling modulated by HDAC4 in skeletal muscle in ALS

Project description:BACKGROUND: Histone deacetylase 4 (HDAC4) has been proposed as a target for the treatment of Amyotrophic Lateral Sclerosis (ALS) because it mediates nerve-skeletal muscle interaction and since its expression in skeletal muscle correlates with the severity of the disease. However, our recent studies on the skeletal muscle response upon long-term denervation highlighted the importance of HDAC4 in maintaining muscle integrity. METHODS: To fully identify the yet uncharacterized HDAC4 functions in ALS, we genetically deleted HDAC4 in skeletal muscles of a mouse model of ALS. Body weight, skeletal muscle, innervation and spinal cord were analyzed over time by morphological and molecular analyses. A transcriptome analysis was also performed to delineate the signaling modulated by HDAC4 in skeletal muscle of a mouse model of ALS. FINDINGS: HDAC4 deletion in skeletal muscle caused earlier ALS onset, characterized by body weight loss, muscle denervation and atrophy, and compromised muscle performance in ALS mice, although the main catabolic pathways were not activated. A transcriptome analysis identified the gene networks modulated by HDAC4 in ALS, revealing UCP1 as a top regulator that may be implicated in worsening ALS features. INTERPRETATION: HDAC4 plays an important role in preserving innervations and skeletal muscle in ALS, likely by modulating the UCP1 gene network. Our study highlights a possible risk in considering HDAC inhibitors for the treatment of ALS.

High througuput sequencing of skeletal muscle-specific Site-1 Protease knockout mouse gastrocnemius and soleus

Project description:The processes by which mitochondria respond to cellular energy demands brought on by physiologic and pathophysiologic stimuli are essential to cellular adaptation and organismal survival. Disrupted mitochondrial function is implicated in several human disease states, underscoring the need to elucidate the molecular mechanisms that control mitochondrial function and metabolism. We previously described a patient with a gain-of-function mutation in Site-1 Protease (S1P) who exhibited idiopathic hyperCKemia, myoedema, and altered muscle mitochondrial morphology. To date, S1P has been heavily characterized in liver and bone, with very little known about its potential function in skeletal muscle. In our current study, we generated a skeletal muscle-specific S1P knockout mouse line (S1PsmKO) to examine the role of S1P in skeletal muscle. S1PsmKO mice were overtly normal in their appearance and health. However, examination of 12-week-old S1PsmKO mice showed increased gastrocnemius muscle mass and aged S1PsmKO mice exhibited increased muscle mass in both gastrocnemius and soleus relative to age-matched controls. Moreover, isolated muscle from S1PsmKO exhibited increased maximal mitochondrial respiration relative to floxed littermates (controls). RNA-Seq analysis showed increased transcript numbers of the mitochondrial-resident gene, Mss51 in S1PsmKO gastrocnemius relative to control mice. Mss51 is a member of the TGF-β/MSTN pathway, which controls mitochondrial metabolism. Similar to S1PsmKO muscle, S1P-depleted C2C12 cells also had increased maximal respiration, which was reversed by exogenous MSS51 expression. These data identify S1P as a regulator of muscle mass and mitochondrial metabolism, and implicate S1P as a novel modulator of TGF-β signaling. Method: Male mice were maintained on standard chow diet until 12 weeks of age.
