RNA-seq from tibialis muscles from rats aged 15 months (adult) and 27 months (old)

Project description:To gain new insights into molecular changes in skeletal muscle aging and disease with a special focus on differential alternative splicing and senescence, we performed RNA-seq on tibialis muscles from 15 months old (adult, a) and 27 months old (old, o) rats. Whole (w) muscle samples were prepared for both age groups (w/a and w/o). Additionally, for both age groups, muscle fibers were isolated. For adult rats, this resulted in one group (f/a). For old rats, fibers were subjected to Laser capture microdissection guided by expression of aging markers Tmem158 and Cdkn1a, giving rise to two groups, aging marker-positive fibers (f/o+) and aging marker-negative fibers (f/o-). The entire experiment comprises 5 groups (w/a, w/o, f/a, f/o+, f/o-), with 5 animals per group, ie. 25 samples total.

Muscle-specific cellular and molecular adaptations to late-life voluntary concurrent exercise in mice [NovoGene]

Project description:Aged mice (22-24 mo) underwent Progressive weighted wheel running (PoWeR) for 8 weeks. RNA-seq on soleus and plantaris muscles was conducted on untrained and PoWeR trained mice. RNA from soleus and plantaris of young mice (4-6 months old) was used as a comparator (Englund et al. 2021 Function)

Genomic and proteomic profiling reveals reduced mitochondrial function and disruption of the neuromuscular junction driving rat sarcopenia

Project description:Molecular mechanisms underlying sarcopenia, the age-related loss of skeletal muscle mass and function, remain unclear. To identify molecular changes that correlated best with sarcopenia and might contribute to its pathogenesis, we determined global gene expression profiles in muscles of rats aged 6, 12, 18, 21, 24, and 27 months. These rats exhibit sarcopenia beginning at 21 months. Correlation of the gene expression versus muscle mass or age changes, and functional annotation analysis identified gene signatures of sarcopenia distinct from gene signatures of aging. Specifically, mitochondrial energy metabolism (e.g., tricarboxylic acid cycle and oxidative phosphorylation) pathway genes were the most downregulated and most significantly correlated with sarcopenia. Also, perturbed were genes/pathways associated with neuromuscular junction patency (providing molecular evidence of sarcopenia-related functional denervation and neuromuscular junction remodeling), protein degradation, and inflammation. Proteomic analysis of samples at 6, 18, and 27 months confirmed the depletion of mitochondrial energy metabolism proteins and neuromuscular junction proteins. Together, these findings suggest that therapeutic approaches that simultaneously stimulate mitochondrogenesis and reduce muscle proteolysis and inflammation have potential for treating sarcopenia.

Proteome profiling in aging rat brain by LC-MS/MS

Project description:This study investigated proteome profile in the hippocampus, medial prefrontal cortex (mPFC), and striatum of 14, 18, 23, and 27 months old rats in order to see the effect of aging on proteins in these regions. Using ultrahigh performance liquid chromatography coupled with Q Exactive HF Orbitrap mass spectrometry, we identified 1074 proteins in the hippocampus, 871 proteins in the mPFC, and 241 proteins the striatum. Ninety-seven, 25, and 5 of these proteins were differentially expressed with age in the hippocampus, mPFC, and striatum, respectively. Overall, aging causes divergent protein changes in specific brain regions, with the most prominent changes observed in the late-aged.
