Molecular insights into human soleus muscle atrophy development: long-term dry immersion effects on the transcriptomic profile and post-translational signaling

Project description:Muscle disuse results in complex signaling alterations followed by structural and functional changes, such as atrophy, force decrease and slow-to-fast fiber-type shift. Little is known about human skeletal muscle signaling alterations under long-term muscle disuse. In this study, we describe the effects of 21-day dry immersion on human postural soleus muscle. We performed both transcriptomic analysis and Western blots to describe the states of the key signaling pathways regulating soleus muscle fiber size, fiber-type, and metabolism. 21-day dry immersion resulted in both slow-type and fast-type myofibers atrophy, downregulation of rRNA content, and mTOR signaling. 21-day dry immersion also leads to slow-to-fast fiber-type and gene expression shift, upregulation of p-eEF2, p-CaMKII, p-ACC content and downregulation of NFATc1 nuclear content. It also caused massive gene expression alterations associated with calcium signaling, cytoskeletal parameters, and downregulated mitochondrial signaling (including fusion, fission, and marker of mitochondrial density).

Rapid changes in transcriptomic profile and mitochondrial function in human soleus muscle after three-day dry immersion

Project description:We aimed to explore the effect of the 3-day dry immersion - a model of physical unloading - on mitochondrial function, transcriptomic and proteomic profiles in a slow-twitch m. soleus of six healthy females. We registered that a marked reduction (25-34%) in the ADP-stimulated respiration in permeabilized muscle fibers was not accompanied by a decrease in the content of mitochondrial enzymes (mass spectrometry-based quantitative proteomics), hence it is related to the disruption in regulation of respiration. We detected a widespread change in the transcriptomic profile (RNA-seq) upon dry immersion. Down-regulated mRNAs were strongly associated with mitochondrial function, as well as with lipid metabolism, glycolysis, insulin signaling, and various transporters. Despite the substantial transcriptomic response, we found no effect on the content of highly abundant proteins (sarcomeric, mitochondrial, chaperon and extracellular matrix-related, etc.) that may be explained by long half-life of these proteins. We suggest that during short-term disuse the content of some regulatory (and usually low abundant) proteins such as cytokines, receptors, transporters, transcription regulators is largely determined by its mRNA concentration. These mRNAs revealed in our work may serve as putative targets for the future studies aimed at developing the approaches for the prevention of muscle deconditioning-induced by disuse.

PROTEOMIC CHARACTERIZATION OF DRY BLOOD SPOTS OF HEALTHY WOMEN DURING SIMULATION THE MICROGRAVITY EFFECTS USING DRY IMMERSION

Project description:This study is unique in that it was the first time that it was the female response to microgravity simulated by 3-day dry immersion that was analyzed. The result of the choice of the object of research fell on dry blood spots, since the technique of capillary blood sampling is less invasive and allows sampling with a greater frequency. This allows researchers to analyze the changes caused by dry immersion in stages and observe the unfolding of the adaptive response taking into account the time of exposure to the experimental conditions.

Jakyak-gamcho-tang ameliorates dexamethasone (DEX)-induced muscle atrophy and muscle dysfunction [Gastrocnemius and Soleus]

Project description:Jakyak-gamcho-tang (JGT) is a herbal medicine that has been traditionally prescrived for pain control including muscular pain. Muscle atrophy is a disease that is characterized with a gradual muscle loss. Muscle atrophy is clearly observed in experimental animals that receive a repeated high-dose of an artificial glucocorticoid, dexamethasone (DEX). This transcriptome analysis aims to investigate the changes in global gene expression profiles in gastrocnemius (GA) and soleus (SO) muscle tissues from mice with DEX-induced muscle atrophy in the presence or absence of JGT co-treatment.

RNA-Seq transcriptome profiling of soleus from adult and aged mice following disuse muscle atrophy and recovery

Project description:Rodent hind limb unloading was used as a model for reduced muscle activity and eventual atrophy. After a 10 day period of unloading, mice in this study were “reloaded” for 3 days and regained use of their hind limbs. We report the application of Next-generation sequencing (NGS) technology for high-throughput profiling of mRNA in soleus muscle of adult (6 mo) and aged (22-24 mo) mice. Our goal was to determine the effects of hind limb unloading and reloading on mRNA profiles in soleus muscle and compare between adult and aged mice. We find that there are distinct response in the profile of fatty acid oxidation, TCA cycle, ETC oxidative phosphorylation gene expression patterns in response to unloading and reloading. The repsonses are generally simialr between young and old mice.

Integrated Proteomic and Metabolomic Analysis of Muscle Atrophy Induced by Hindlimb Unloading

Project description:Skeletal muscle atrophy, which is induced by factors such as disuse, spaceflight, certain medications, neurological disorders, and malnutrition, is a global health issue lacking effective treatment. Hindlimb unloading is a commonly used model for muscle atrophy. However, the underlying mechanism of muscle atrophy induced by hindlimb unloading remains unclear, particular from the perspective of myocyte proteome and metabolism. We first used mass spectrometry for proteomic sequencing and untargeted metabolomics to analyze soleus muscle changes in rats with hindlimb unloading. The study found 1052 proteins and 377 metabolites (with MS2 name) differentially expressed between HU group and CON group. Proteins like ACTN3, MYH4, MYBPC2, and MYOZ1, typically found in fast-twitch muscles, were upregulated, along with metabolism-related proteins GLUL, GSTM4, and NDUFS4. Metabolites arachidylcarnitine and 7,8-dihydrobiopterin, and pathways like histidine, taurine, and hypotaurine metabolism were linked to muscle atrophy. Protein and metabolism joint analysis revealed that some pathways such as glutathione metabolism, ferroptosis and lysosome pathways were likely to be involved in soleus atrophy. In this study, we have applied integrated deep proteomic and metabolomic analysis. The upregulation of proteins which are expressed in fast-twitch fibers indicated the conversion of slow-twitch fibers to fast-twitch fibers under HU. Some metabolism-related proteins have been screened out. Besides, some differentially abundant metabolites and pathways revealed the important role of metabolism in the muscle atrophy of soleus. Our study provides insights into the pathogenesis and treatment of muscle atrophy that results from unloading by integrating the proteomics and metabolomics of soleus muscles.

Expression profiling of soleus muscle under the effect of simulated spaceflight

Project description:Spaceflight imposes the risk of skeletal muscle atrophy for astronauts. The understanding of muscle atrophy because of spaceflight is limited, but continued efforts are essential for developing countermeasures of this effect. A distinct difference between spaceflight-induced muscle atrophy and other forms of atrophy is the additional effect of cosmic rays in outer space. To study spaceflight-induced muscle atrophy, we performed two ground-based models of microgravity in a low dose radiation environment and studied transcriptional changes in rat soleus muscle using microarray technology.

miRNAs expression of soleus response to simulated microgravity

Project description:Identification of gravisensitive miRNAs expression in rat soleus muscle exposed to 7 and 14 days of Hindlimb suspension (HS) simulated microgravity. Microgravity causes muscle atrophy possibly due to muscle wasting overtake regeneration. Results provide insight into the molecular mechanisms regulating muscle atrophy. The expression of 23 out of 174 miRNAs was found to change at least 2-fold of 7 and/or 14 days of TS. By using real-time PCR assays, we verified the microarray data using some of the expected genes.
