RNA-seq analysis of skeletal muscle-specific Crls1 knockout (MUCKO) mice reveals fiber-type-dependent transcriptional remodeling in Soleus and EDL

ABSTRACT: Cardiolipin (CL) is a mitochondria-specific phospholipid essential for inner membrane architecture and respiratory chain function. To determine how loss of CL biosynthesis affects skeletal muscle transcriptional programs in a fiber-type-dependent manner, we generated skeletal muscle-specific Crls1 knockout mice (MUCKO) and performed bulk mRNA sequencing on two functionally distinct muscles: the oxidative Soleus and the glycolytic Extensor Digitorum Longus (EDL). RNA-seq was performed on MUCKO and littermate control mice for both muscle types, enabling comparison of CL-depletion-induced gene expression changes across oxidative and glycolytic fiber contexts. This dataset supports findings that cardiolipin loss drives fiber-type-specific transcriptional and metabolic adaptations, including differential regulation of proteostasis and lipid-handling pathways between oxidative and glycolytic muscle.

Advanced fiber type-specific protein profiles derived from adult murine skeletal muscle

Project description:Skeletal muscle is a heterogeneous tissue consisting of blood vessels, connective tissue, and muscle fibers. The last are highly adaptive and can change their molecular composition depending on external and internal factors, such as exercise, age, and disease. Thus, examination of the skeletal muscles at the fiber type level is essential to detect potential alterations. Therefore, we established a protocol in which myosin heavy chain isoform immunolabeled muscle fibers were laser microdissected and separately investigated by mass spectrometry to develop advanced proteomic profiles of all murine skeletal muscle fiber types. Our in-depth mass spectrometric analysis revealed unique fiber type protein profiles, confirming fiber type-specific metabolic properties and revealing a more versatile function of type IIx fibers. Furthermore, we found that multiple myopathy-associated proteins were enriched in type I and IIa fibers. To further optimize the assignment of fiber types based on the protein profile, we developed a hypothesis-free machine-learning approach (available at: https://github.com/mpc-bioinformatics/FiPSPi), identified a discriminative peptide panel, and confirmed our panel using a public data set.

Cold induced transcriptome change in skeletal muscle

Project description:Exposure to cold temperatures is known to mimic the effects of exercise, protecting against obesity and improving metabolic health. Cold is known to act through the sympathetic nervous systems and -adrenergic signaling, but here we report that cold temperature can directly activate a variety of gene programs in muscle independent of -adrenergic signaling.

Transcriptional analysis of genes regulating the mitochondrial dNTP pool in muscle cells.

Project description:Mutations in genes involved in dNTP metabolism can lead to tissue-specific mitochondrial depletion syndromes (MDS), likely because the expression of key enzymes is reduced to critical levels in post mitotic cells. Our goal was to establish an in vitro skeletal muscle cell model to study the muscle specificity of MDS associated with mitochondrial dNTP pool imbalance. We performed a comprehensive analysis at the mRNA level of enzymes and transporters responsible for dNTP pool imbalance in muscle cells in vitro and in vivo. Agilent Mouse Oligo Arrays 4x44K were utilized to examine expression levels in proliferating and differentiated C2C12 cells as well as in the mouse EDL (fast glycolytic) and soleus (slow oxidative) muscles. The comparison of mRNA expression profiles supports the reliability of our in vitro cell system. Proliferating mouse C2C12 myoblasts were collected at about 50 percent confluence. Myoblasts were then induced to differentiate in vitro into myotubes that were harvested after 96 hours and further purified to reduce the contribution of mononucleated cells present in the culture. Gene expression in C2C12 myoblasts and myotubes was compared with fully differentiated muscle fibers in vivo. To this aim, the extensor digitorum longus (EDL) and soleus hind limb muscles were isolated from adult CD1 mice. These muscles were selected because they have different metabolic (glycolytic vs. oxidative) and twitching (fast vs. slow) properties. Triplicate total RNA samples were submitted to gene expression profiling.

Proteome of FAO deficient mouse model

Project description:Objective: Skeletal muscle is a heterogeneous and dynamic tissue that adapts to functional demands and substrate availability by modulating muscle fiber size and type. The concept of muscle fiber type relates to its contractile (slow or fast) and metabolic (glycolytic or oxidative) properties. Here, we tested whether disruptions in muscle oxidative catabolism are sufficient to prompt parallel adaptations in energetics and contractile protein composition. Conclusion: The loss of mitochondrial long-chain fatty acid oxidation elicits an adaptive response involving conversion of oxidative muscle towards a metabolic profile that resembles a glycolytic muscle but that is not accompanied by changes in myosin heavy chain isoforms. These data suggest that shifts in muscle catabolism are not sufficient to drive shifts in the contractile apparatus but are sufficient to drive adaptive changes in metabolic properties.

Transcription profiling of skeletal muscle from wild type and PGC-1 beta transgenic mice

Project description:Skeletal muscle must perform a wide range of kinds of work, and different fiber types have evolved to accommodate these different tasks. The attributes of fibers are determined in large part by the coordinated regulation of oxidative capacity, as reflected by mitochondrial content, and the specific makeup of myofibrillar proteins. Adult muscle fibers contain four myosin heavy chain isotypes: I, IIa, IIx and IIb. Type I and IIa fibers have slower twitches and are rich in mitochondria, while type IIb fibers are fast-twitch and predominantly glycolytic. The intermediate IIx fibers are less well understood. Previous work had shown that the transcriptional coactivator PGC-1 alpha could drive the formation of type I and IIa muscle fibers. We show here that mice with transgenic expression of PGC-1 beta in skeletal muscle results in marked induction of IIx fibers. The fibers in transgenic mice are rich in mitochondria and are highly oxidative. As a result, PGC-1 beta transgenic animals can perform oxidative activity for longer and at higher work loads than wild type animals. In cell culture, PGC-1 beta coactivates the MEF2 family of transcription factors to stimulate the MHC IIx promoter. Together, these data indicate that PGC-1 beta is sufficient to drive the formation in vivo of highly oxidative fibers with type IIx characteristics.

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.
