TL;DR
Scientists studied all the proteins in mitochondria (the tiny powerhouses inside our cells) to understand how they work and what goes wrong when people get sick with diseases like cancer, diabetes, and brain problems. By mapping out which proteins do what jobs in mitochondria, researchers can better figure out why these diseases happen and how to fix them.

Summary
Researchers conducted a comprehensive review of mitochondrial proteomics - the study of proteins within cellular powerhouses called mitochondria. These organelles control energy production and multiple cellular pathways. The scientists examined how protein analysis can reveal mitochondrial dysfunction in various diseases including inherited metabolic disorders, cancer, diabetes, and neurological conditions. They outlined systematic approaches for analyzing mitochondrial protein pathways and their connections to disease development. The review emphasizes that comprehensive protein analysis with rigorous data interpretation is essential for understanding how mitochondrial problems contribute to disease and could enable better research into potential treatments.
Abstract
Introduction: Mitochondria contain multiple pathways including energy metabolism and several signaling and synthetic pathways. Mitochondrial proteomics is highly valuable for studying diseases including inherited metabolic disorders, complex and common disorders like neurodegeneration, diabetes, and cancer, since they all to some degree have mitochondrial underpinnings. Areas covered: The main mitochondrial functions and pathways are outlined, and systematic protein lists are presented. The main energy metabolic pathways are as follows: iron-sulfur cluster synthesis, one carbon metabolism, catabolism of hydrogen sulfide, kynurenines and reactive oxygen species (ROS), and others, described with the aim of laying a foundation for systematic mitochondrial pathway analysis based on proteomics data. The links of the proteins and pathways to functional effects and diseases are discussed. The disease examples are focussed on inherited metabolic disorders, cancer, neurological, and cardiovascular disorders. Expert opinion: To elucidate the role of mitochondria in health and disease, there is a need for comprehensive proteomics analyses with stringent, systematic data treatment for proper interpretation of mitochondrial pathway data. In that way, comprehensive hypothesis-based research can be performed based on proteomics data.
