Involvement of MicroRNAs in the regulation of muscle wasting during catabolic conditions

Abstract

Background: MicroRNAs are important modulators of gene expression but their role in the atrophy program and in muscle loss is unknown. Results: miRNA-206 and miRNA-21 are critical for regulation of the atrophy program after denervation. Conclusion: miRNAs are important for the fine-tuning of the atrophy program. Significance: Modulating miRNA expression is a novel potential therapeutic approach for counteracting muscle loss and weakness in catabolic conditions. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.
