Mechano-regulated tenascin-C orchestrates muscle repair.

Tenascin-C (TNC) is a mechano-regulated, morphogenic, extracellular matrix protein that is associated with tissue remodeling. The physiological role of TNC remains unclear because transgenic mice engineered for a TNC deficiency, via a defect in TNC secretion, show no major pathologies. We hypothesized that TNC-deficient mice would demonstrate defects in the repair of damaged leg muscles, which would be of functional significance because this tissue is subjected to frequent cycles of mechanical d ...[more]

A Dach2-Hdac9-Myog-Gdf5 signaling system regulates regeneration of neuromuscular synapses

Project description:Muscle denervation due to injury, disease or aging results in impaired motor function. Restoring neuromuscular communication requires axonal regrowth and regeneration of neuromuscular synapses. Muscle activity inhibits neuromuscular synapse regeneration. The mechanism by which muscle activity regulates regeneration of synapses is poorly understood. Dach2 and Hdac9 are activity-regulated transcriptional co-repressors that are highly expressed in innervated muscle and suppressed following muscle denervation. Here, we report that Dach2 and Hdac9 inhibit regeneration of neuromuscular synapses. Importantly, we identified Myog and Gdf5 as muscle-specific Dach2/Hdac9-regulated genes that stimulate neuromuscular regeneration in denervated muscle. Interestingly, Gdf5 also stimulates presynaptic differentiation and inhibits branching of regenerating neurons. Finally, we found that Dach2 and Hdac9 suppress miR206 expression, a microRNA involved in enhancing neuromuscular regeneration. RNAseq on innervated and 3 day denervated adult soleus muscle from wildtype mice is compared with that from 3 day denervated soleus muscle from Dach2/Hdac9 deleted mice to identify Dach2/Hdac9-regulated genes.

MicroRNA expression in rat soleus muscle during atrophy induced by hindlimb suspension

Project description:The objective of the study was to identify microRNAs expressed in the rat soleus muscle and determine if their expression was changed in response to hindlimb suspension. The microRNA expression profile (Sanger miRBase 9.0) of the rat soleus muscle was determined in the following three groups: control (C), hindlimb suspended for 2 days (HS-2) or 7 days (HS-7). Three replicates were performed for each group.

Targeted genetical genomic to identify genetic mechanisms affecting complex traits: example of meat pH in the chicken

Project description:Abstract:Genetical genomics has been suggested and proven to be a powerful approach to study the genotype-phenotype gap. However, the relatively low power of these experiments (usually related to the high cost) has hindered fulfilment of its promise, especially for loci (QTL) of moderate effects. One strategy to overcome the issue is to use a targeted approach: to focus the experiment on one QTL of particular interest. It has two clear advantages: (i) It reduces the problem to a simple comparison between different genotypic groups at the QTL and (ii) it is a good starting point to investigate downstream effects of the QTL. In the present study, from 698 F2 birds used for QTL mapping, gene expression profiles of 24 (12 from each homozygote genotypes at the QTL) were investigated. The targeted QTL was located on chromosome 1 and affected initial pH of meat. The biological mechanisms controlling this trait can be similar to those affecting malignant hyperthermia or muscle fatigue in human. The gene expression study identified ten strong local signals (potentially cis-eQTL) which were markedly more significant compared to the rest of the genome. The differentially expressed genes all mapped to a region < 1 Mb, suggesting a remarkable reduction of the QTL interval compared to the linkage study. These results combined with analysis of downstream effect of the QTL (using gene network analysis) suggest that the QTL is controlling pH by governing oxidative stress. The eQTL results were reproducible with using as few as 4 arrays on pooled samples (with lower significance level). The results demonstrate that this cost effective approach is promising not only for characterization of a QTL also for studying its downstream effects. there are 24 samples from to different genotypes. Each group of genotype has 12 samples. The two groups are compared using a dye balanced design.

Effect of insulin insufficiency on ultrastructure and function in skeletal muscle

Project description:Decreased insulin availability and high blood glucose levels, the hallmark features of poorly controlled diabetes, drive disease progression and are associated with decreased skeletal muscle mass. We have shown that mice with -cell dysfunction and normal insulin sensitivity have decreased skeletal muscle mass. This project asks how insulin deficiency impacts on the structure and function of the remaining skeletal muscle in these animals. Methods: Skeletal muscle function was determined by measuring exercise capacity and specific muscle strength prior to and after insulin supplementation for 28 days in 12-week-old mice with conditional -cell deletion of the ATP binding cassette transporters ABCA1 and ABCG1 (β-DKO mice). Abca1 and Abcg1 floxed (fl/fl) mice were used as controls. RNAseq was used to quantify changes in transcripts in soleus and extensor digitorum longus muscles. Skeletal muscle and mitochondrial morphology were assessed by transmission electron microscopy. Myofibrillar Ca2+ sensitivity and maximum isometric single muscle fibre force were assessed using MyoRobot biomechatronics technology. Results: RNA transcripts were significantly altered in β-DKO mice compared to fl/fl controls (32 in extensor digitorum longus and 412 in soleus). Exercise capacity and muscle strength were significantly decreased in β-DKO mice compared to fl/fl controls (p = 0.012), and a loss of structural integrity was also observed in skeletal muscle from the β-DKO mice. Supplementation of β-DKO mice with insulin restored muscle integrity, strength and expression of 13 and 16 of the dysregulated transcripts in and extensor digitorum longus and soleus muscles, respectively. Conclusions: Insulin insufficiency due to -cell dysfunction perturbs the structure and function of skeletal muscle. These adverse effects are rectified by insulin supplementation.
