The human skeletal muscle transcriptome – sex differences, alternative splicing and tissue homogeneity assessed with RNA sequencing

ABSTRACT: The amount of RNA sequencing data on skeletal muscle is very limited. We have analyzed a large set of human muscle biopsy samples and provide extensive information on the baseline skeletal muscle transcriptome, including completely novel protein-coding transcripts.

Stockholm dataset for ageing prototype diagnostic

Project description:Muscle biopsy samples from healthy male subjects at the baseline belonging to either <29y or >59y age range. These samples were used to design a prototype of multi-tissue molecular diagnostic of healthy physiological age. Resting skeletal muscle sample after an overnight fast. related to GSE18583

Baseline skeletal muscle gene expression

Project description:Muscle biopsy samples were obtained from two groups of male subjects prior to endurance training. The samples were used to predict training responses. Baseline gene expression involving 30 probe sets was able to classify subjects into high and low responders. Resting skeletal muscle sample after an overnight fast.

Contractile activity-specific transcriptome response to acute endurance exercise and training in human skeletal muscle

Project description:In our study, we investigated for contractile activity-specific changes in the transcriptome in untrained and trained (after an aerobic training programme) human skeletal muscle. The second goal was to examine effect of aerobic training on gene expression in muscle at baseline (after long term training). Seven untrained males performed the one-legged knee extension exercise (for 60 min) with the same relative intensity before and after a 2 month aerobic training programme (1 h/day, 5/week). Biopsy samples were taken at rest (baseline condition, 48 h after exercise), 1 and 4 h after the one-legged exercise from m. vastus lateralis of either leg. Comparison of gene expression in exercised leg with that in non-exercised [control] leg allowed us to identify contractile activity-specific genes in both untrained and trained skeletal muscle, i.e., genes that play a key role in adapting to acute exercise, regardless of the level of fitness. RNA-sequencing (84 samples in total; ~47 million reads/sample) was performed by NextSeq 500 and HiSeq 2500 (Illumina). Two months aerobic training increased the aerobic capacity of the knee-extensor muscles (power at anaerobic threshold in the incremental one-legged and cycling tests), the maximum rate of ADP-stimulated mitochondrial respiration in permeabilized muscle fibres and amounts of oxidative phosphorylation proteins. Contractile activity-specific changes in the transcriptome in untrained and trained human skeletal muscle were revealed for the first time. After 2 month aerobic training, transcriptome responses specific for contractile activity in trained muscle substantially decreased relative to those in untrained muscle. We found out that adaptation of skeletal muscle to regular exercise is associated not only with a transient change in the transcriptome after each stress (acute exercise), but also with a marked change in baseline expression of many genes after repeated stress (e.g., long term training).

The muscle proteome reflects changes in mitochondrial function, cellular stress and proteolysis after 14 days of unilateral lower limb immobilization in active young men

Project description:Skeletal muscle unloading due to joint immobilization induces skeletal muscle atrophy. However, the skeletal muscle proteome response to limb immobilization has not been investigated using SWATH methods. This study quantitatively characterized the muscle proteome at baseline, and after 3 and 14 d of unilateral lower limb (knee-brace) immobilization in 18 healthy young men (25.4 ±5.5 y, 81.2 ±11.6 kg). All muscle biopsies were obtained from the vastus lateralis muscle. Unilateral lower limb immobilization was preceded by four-weeks of exercise training to standardise acute training history, and 7 days of dietary provision to standardise energy/macronutrient intake. Dietary intake was also standardised/provided throughout the 14 d immobilization period.

Vastus lateralis muscle biopsy: post-expedition vs. pre-expedition

Project description:To define the skeletal muscle adaptations induced by exercise performed at high altitude hypoxia, we investigated if the gene expression profile of Vastus lateralis muscle was affected by 5000 m-above-sl-expedition. Two-condition experiment, Vastus lateralis muscle biopsy post-expedition vs Vastus lateralis muscle biopsy pre-expedition. Five volunteers/climbers. Biological replicates: 1 pre-expedition sample, 1 post-expedition sample.
