Mitochondria have recently emerged as central regulators of TNBC pathogenesis, functioning beyond their traditional roles as cellular powerhouses. This article synthesizes current understanding of how mitochondrial metabolic reprogramming\u2014particularly the synergistic hyperactivation of oxidative phosphorylation, fatty acid oxidation, and glutamine metabolism\u2014drives TNBC progression, metastasis, and chemoresistance. We further examine the dichotomous roles of mitochondrial dynamics and mitophagy in shaping tumor cell fate, and explore how mitochondria orchestrate diverse programmed cell death pathways and immune modulation. Translational strategies targeting mitochondrial vulnerabilities, including small-molecule inhibitors, nanomaterial-based delivery systems, and combination regimens, are critically evaluated. Despite significant preclinical promise, challenges including tumor selectivity, metabolic plasticity, and clinical translation remain. By integrating mechanistic insights with emerging therapeutic innovations, this perspective highlights the transformative potential of mitochondria-targeted interventions for future TNBC management.<\/jats:p>","DOI":"10.3389\/fonc.2026.1837476","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T04:33:15Z","timestamp":1781757195000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["The
