microRNAs and muscle disorders.
MicroRNAs (miRNAs) are a class of non-coding regulatory RNAs of approximately 22 nucleotides in length. miRNAs are highly conserved across a number of species, including plants, worms and humans. miRNAs regulate gene expression post-transcriptionally, primarily by associating with the 3' untranslated region (UTR) of their regulatory target mRNAs. Recent work has begun to reveal roles for miRNAs...
متن کاملMicroRNAs in the regeneration of skeletal muscle.
MicroRNAs (miRNAs) have emerged as critical regulators of numerous biological processes by modulating gene expression at the post-transcriptional level. The discovery of miRNAs as new and important regulators of gene expression is expected to broaden our biological understanding of the regulatory mechanism in muscle by adding another dimension of regulation to the diversity and complexity of ge...
متن کاملRole of microRNAs in skeletal muscle hypertrophy
Skeletal muscle comprises approximately 40% of body weight, and is important for locomotion, as well as for metabolic homeostasis. Adult skeletal muscle mass is maintained by a fine balance between muscle protein synthesis and degradation. In response to cytokines, nutrients, and mechanical stimuli, skeletal muscle mass is increased (hypertrophy), whereas skeletal muscle mass is decreased (atro...
متن کاملMicroRNAs in Muscle: Characterizing the Powerlifter Phenotype
Powerlifters are the epitome of muscular adaptation and are able to generate extreme forces. The molecular mechanisms underpinning the significant capacity for force generation and hypertrophy are not fully elucidated. MicroRNAs (miRs) are short non-coding RNA sequences that control gene expression via promotion of transcript breakdown and/or translational inhibition. Differences in basal miR e...
متن کامل01-P004 MicroRNAs in muscle development
revealed a marked reduction in radial thickness starting at E13.5, and defective postnatal cortical layering. Whereas the former was due to neuronal apoptosis starting at E12.5, which was the earliest detectable phenotype, the latter reflected dramatic impairment of neuronal differentiation. Remarkably, the primary target cells of Dicer ablation, the neuroepithelial cells, and the neurogenic pr...
