Raises a question worth testing. It does not answer one.
This is a narrative review of mitochondrial transfer mechanisms in tumors and their potential role in metabolic plasticity, stress tolerance, and therapy resistance. The article synthesizes mechanistic and cell-biological evidence and identifies regulatory 'gatekeepers' as candidate intervention targets, but does not report original empirical data or clinical validation of these concepts.
Narrative review. Tumor cells and tumor microenvironment; no specific patient population studied.
Mitochondrial transfer occurs via actin-based tunneling nanotubes, extracellular vesicle-mediated export and uptake, and contact-dependent mechanisms Transfer can buffer oxidative stress, compensate for mtDNA damage, and restore oxidative phosphorylation in recipient cells MIRO1/2-TRAK-motor coupling and EV biogenesis/uptake modules identified as regulatory 'gatekeepers' constraining transfer efficiency
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The review identifies potential therapeutic targets (mitochondrial transfer conduits and regulatory gatekeepers) and emphasizes the need for methodological rigor in validating mitochondrial exchange. Clinicians should view this as conceptual foundation work requiring subsequent empirical and clinical validation before translation.

What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Mitochondrial transfer has emerged as a previously underappreciated mode of intercellular communication with major implications for tumor biology. Beyond their cell-autonomous roles in bioenergetics and signalling, mitochondria can be exchanged between cells as intact organelles or as mitochondrial cargo, thereby reshaping the metabolic state, stress tolerance and therapy responsiveness of recipient cells. In tumors, mitochondrial transfer can buffer oxidative stress, compensate for mtDNA damage and restore oxidative phosphorylation, enabling metabolic plasticity and contributing to immune dysfunction within the tumor microenvironment. This review synthesized current evidence for the structural routes and regulatory logic of mitochondrial exchange in cancer, spanning actin-based tunneling nanotubes, extracellular vesicle-mediated export and uptake, and other contact-dependent mechanisms. We highlight actionable "gatekeepers" that constrain transfer efficiency, including conduit biogenesis programs, MIRO1/2-TRAK-motor coupling that licenses mitochondrial trafficking, and EV biogenesis/uptake modules, as well as microenvironmental triggers such as hypoxia and redox stress. We also evaluate emerging methodological standards required to distinguish bona fide organelle transfer from dye leakage or indirect cargo exchange, and discuss how orthogonal validation (genetic reporters, mtDNA barcoding and functional rescue assays) can improve rigor and comparability across studies. By integrating current findings, this article aims to provide a theoretical foundation and strategic guidance for targeting tumor metabolic regulation and improving precision oncology approaches.
