(Submitter supplied) The molecular mechanisms underlying the sex differences in human muscle morphology and function remain to be elucidated. The purpose of the study was to detect the sex differences in the skeletal muscle transcriptome in both the resting state and following anabolic stimuli, resistance exericse.

(Submitter supplied) A common characteristic of aging is the loss of skeletal muscle (sarcopenia) which can lead to falls and fractures. MicroRNAs (miRNA) are novel post-transcriptional modulators of gene expression with a potential role as a regulator of skeletal muscle mass and function. The purpose of this study was to profile miRNA expression patterns in aging human skeletal muscle using a miRNA array followed by in-depth functional and network analysis. more...

(Submitter supplied) Comparative effects of Duchenne Muscular Dystrophy (DMD) and Aging in skeletal muscle Expression profiling established by microarray technology provides a powerful tool by which complex pathways can be assembled. The pathophysiology of Duchenne Muscular Dystrophy (DMD) is a complex process involving many pathways downstream of the primary genetic insult (lack of dystrophin). Similarly, the mechanisms implicated in muscle aging are only partially understood. more...

(Submitter supplied) Sarcopenia is an age-associated loss of skeletal muscle mass and strength that increases the risk of disability. Calorie restriction (CR), the consumption of fewer calories while maintaining adequate nutrition, mitigates sarcopenia and many other age-related diseases. To identify potential mechanisms by which CR preserves skeletal muscle integrity during aging, we used mRNA-Seq for deep characterization of gene regulation and mRNA abundance in skeletal muscle of old mice compared with old mice subjected to CR. more...

(Submitter supplied) Human aging is associated with skeletal muscle atrophy and functional impairment (sarcopenia). Multiple lines of evidence suggest that mitochondrial dysfunction is a major contributor to sarcopenia. We evaluated whether healthy aging was associated with a transcriptional profile reflecting mitochondrial impairment and whether resistance exercise could reverse this signature to that approximating a younger physiological age. more...
