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.

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.

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.

Project description:Identification of gravisensitive gene 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 787 (373 upregulated and 414 downregulated) and 923 (491 upregulated and 432 downregulated) genes out of 28000 was altered respectively at least 2-fold of 7 and 14 days TS, which represented 397 (233 upregulated and 164 downregulated) genes of common alteration. By using real-time PCR assays, we verified the microarray data using some of the expected genes.

Project description:In this work we employed classic skeletal muscle unloading rat model to determine how hindlimb suspension (HS) affects functional activity of skeletal muscle progenitor cells (SMPC). We have purified SMPC from m. soleus from control rats and after 1, 3, 7 and 14 days of exposure (HS1, HS3, HS7, HS14).
