The transcriptomic signature of myostatin inhibitory influence on the differentiation of mouse C2C12 myoblasts


ABSTRACT: GDF8 (myostatin) is a unique cytokine strongly affecting the skeletal muscle phenotype in human and animals. The aim of the present study was to elucidate the molecular mechanism of myostatin influence on the differentiation of mouse C2C12 myoblasts, using the global-transcriptome analysis with the DNA microarray technique. Treatment with exogenous GDF8 strongly affected the growth and development of C2C12 mouse myoblasts. This was manifested by the inhibition of proliferation and differentiation as well as the impairment of cell fusion. DNA microarray analysis revealed 778 genes regulated by GDF8 in differentiating myoblasts (543 down-regulated and 235 up-regulated). Ontological analysis revealed their involvement in 17 types of biological processes, 10 types of molecular functions and 68 different signaling pathways. The effect of GDF8 was mainly mediated by the disruption of the cell cycle, calcium and insulin signaling pathways and expression of cytoskeletal and muscle specific proteins. The identified key-genes that could play a role as GDF8 targets in differentiating myoblasts are: Mef2, Hgf, Ilb1, Itgb1, Edn1, Ppargc1a. After scanning of hybridized microarrays, quantitation of slide images was performed using Feature Extraction Software (Agilent) using default parameters. The raw data were normalized by Loess normalization method, and then the normalized raw data was exported to GeneSpring GX 11.0.5 (Agilent, Santa Clara, CA). For identification of genes significantly altered in cell compared with the control normal gene set, total detected entities were filtered by flags (present, marginal) to remove very low signal entities and to select reproducible signal values of entities among the replicated experiments, respectively. In statistical analysis, separated for experiment with myoblasts treated with GDF8 ([C2C12]-[GDF8]1-4) was used t-test unpaired (p < 0.05) and fold change over 1.6. Analysis of GO and signaling pathway was carried out using GeneSpring GX 12 (Agilent), KEGG and PANTHER Classification System (http://www.pantherdb.org/). In the analysis of signaling pathways using Panther, a total of 68 cellular pathways were identified.
