Expert Review of Proteomics
|January 20, 2021
Summary
Regular exercise protects against disease and extends healthspan by improving muscle physiology. Proteomic studies reveal how muscle adapts to physical activity, offering new insights into exercise benefits.
Area of Science:
- Exercise physiology
- Proteomics
- Muscle biology
Background:
- Striated muscle is key to physical work and exercise benefits.
- Exercise counters age-related physiological decline and prevents non-communicable diseases.
- Proteomic analysis of muscle reveals exercise's protective effects.
Purpose of the Study:
- To review key findings in muscle exercise physiology from the last decade.
- To highlight insights gained from proteomic surveys of muscle.
- To discuss new methods for dynamic proteome profiling in muscle adaptation.
Main Methods:
- Liquid-chromatography tandem mass spectrometry (LC-MS/MS) of peptide digests.
- Proteomic analysis of muscle mitochondrial fractions.
- Enrichment techniques for post-translational modifications (phosphorylation, acetylation, ubiquitination).
Main Results:
- LC-MS/MS is a primary method for muscle proteomic studies.
- Site-specific analysis of post-translational modifications is a growing interest.
- Dynamic proteome profiling offers insights into protein turnover (synthesis and degradation).
Conclusions:
- Proteomic surveys provide valuable insights into muscle adaptation to exercise.
- Emerging dynamic proteome profiling methods enhance understanding of muscle plasticity.
- Exercise proteomics is crucial for understanding healthspan extension and disease prevention.

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

2.1K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
