Mass spectrometry-based proteomics approaches to interrogate skeletal muscle adaptations to exercise

Daniel T. Cervone et al.

Summary: Recent studies have found that both acute exercise and chronic exercise training have positive effects on the entire body's physiology, which are mainly attributed to significant changes in tissue-specific proteins. Particularly, skeletal muscle, as the major contributor to exercise, has attracted the attention of exercise scientists who aim to uncover adaptive mechanisms resulting in metabolic benefits and performance enhancements from training. With the emergence of mass spectrometry-based proteomics, researchers are now able to study muscle protein dynamics comprehensively from various perspectives. This review highlights recent literature that employs new workflows and advancements in proteomics to deepen our understanding of training-related changes in skeletal muscle. The authors also emphasize the need to explore untapped areas in skeletal muscle proteomics research and address key considerations when applying mass spectrometry-based analyses, especially in the study of human biology. They further encourage researchers to combine omics data with functional analyses to enhance our knowledge of the complex adaptive responses in skeletal muscle during acute and chronic exercise.

Summary: Proteomics is an essential analytical technique for studying biological systems using different proteins. The study compared the qualitative and quantitative performance of two commonly used proteomics techniques, label-free shotgun and 2D-DIGE, using six technical and three biological replicates of the human prostate carcinoma cell line DU145. The results showed that label-free shotgun quickly provides an annotated proteome but with reduced robustness compared to 2D-DIGE, which offers qualitative and quantitative information on proteoforms and post-translational modifications. However, the 2D-DIGE technique requires more time and manual work. Ultimately, this work highlights the different outputs and applications of these two techniques for biological research.

Mapping the Proteoform Landscape of Five Human Tissues

Bryon S. Drown et al.

Summary: To understand the human body's functions, it is necessary to study the relationship between protein structure and function on a large scale. Proteins' chemical structure is regulated at multiple levels, resulting in various products with different functions within cells. The term "proteoform" encompasses the complexity of chemical composition. Mapping the proteoform landscape in human tissues requires sensitive and comprehensive analytical techniques. In this study, a top-down proteomics approach combining capillary zone electrophoresis and nanoflow reversed-phase liquid chromatography was used to identify and characterize proteoforms from different organs. The combination of these techniques provided enhanced coverage of post-translational modifications and proteoforms. Among the identified proteoforms, a significant percentage had not been reported before. The differential regulation of proteoforms in different organs provides insights into their function and regulation in human health and disease.
