Label-Free LC-MS/MS Proteomics Analyses Reveal Proteomic Changes Accompanying MSTN KO in C2C12 Cells
Analysis of the proteome of myostatin (MSTN) knockout (KO) mouse C2C12 cells has proven valuable to studies investigating the molecular mechanisms by which MSTN regulates skeletal muscle development. To identify new protein/pathway alterations and candidate biomarkers for skeletal muscle development, we compared proteomic profiles of MSTN KO C2C12 cells (KO) with corresponding wild-type cells (NC) using a label-free liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique. A total of 2637 proteins were identified and quantified in KO cells. Among these proteins, 77 proteins were significantly differentially expressed, 38 upregulated, and 39 downregulated, in MSTN KO C2C12 cells. These significantly altered proteins are involved in metabolic processes, developmental processes, immune system processes, and the regulation of other biological processes. Enrichment analysis was utilized to link these alterations to biological pathways, which are predominantly related to oxidative phosphorylation, protein digestion and absorption, mitochondrion localisation, antigen processing and presentation, the MAPK signaling pathway, the PPAR signaling pathway, the PI3K-Akt signaling pathway, and the JAK-STAT signaling pathway. Upregulation of several proteins, including epoxide hydrolase, tropomyosin 1, Cyb5a, HTRA1, Cox6a1, CD109, Synap29, and Ugt1a6, likely enhanced skeletal muscle development, the immune system, and energy metabolism. Collectively, our results present a comprehensive proteomics analysis of MSTN KO C2C12 myoblast cells; we hypothesize that MSTN KO could activate p38MAPK signaling pathway by CDC42, and we further deciphered the function of MSTN in the regulation of skeletal muscle development, immune processes, and mitochondrial energy metabolism.
