Mitochondrial metabolic enzyme and transporter

Mitochondrial metabolic enzyme and transporter represent a broad class of proteins essential for cellular energy production, biosynthesis, and signaling. This group includes enzymes involved in the tricarboxylic acid (TCA) cycle, fatty acid oxidation, and oxidative phosphorylation, as well as the SLC25 family of mitochondrial carrier proteins that transport metabolites across the inner mitochondrial membrane (Palmieri, 2013, Molecular Aspects of Medicine). In various pathologies, especially cancer, these metabolic pathways are often hijacked to support increased biosynthetic demands and redox balance, a phenomenon known as metabolic reprogramming (Vander Heiden & DeBerardinis, 2017, Cell). Therapeutic strategies targeting these components include inhibitors of mutant isocitrate dehydrogenase (IDH1/2) and glutaminase (GLS), which have shown clinical efficacy in hematologic malignancies and solid tumors (DiNardo et al., 2018, NEJM). Despite their potential, the ubiquitous nature of mitochondrial function across healthy tissues poses significant risks for systemic toxicity and narrow therapeutic windows (Zong et al., 2016, Molecular Cancer).
