Cancer cells exploit host cell mitochondria
On March 22, 2026, researchers announced that tumor cells exploit nerve cells by directly siphoning functional mitochondria through nanotubes, a process validated in human cancer tissue and observed across various cancer types, including breast and prostate cancer. As of March 22, 2026, this 'energy theft' provides cancer cells with a metabolic advantage, enhancing their survival and proliferation, particularly during metastasis. A new method called MitoTRACER was developed to identify these mitochondria-receiving cancer cells, which were found in higher numbers at metastatic sites in mouse models of breast cancer. This mechanism extends beyond nerve cells, as cancer cells also acquire mitochondria from immune cells, specifically T cells, through nanotubes, highlighting a broader strategy for energy acquisition. This builds on earlier discoveries, such as the finding on August 1, 2025, that breast cancer cells steal mitochondria from neurons to fuel metastasis, increasing ATP content and metastatic capacity.

Tumor Cells Siphon Mitochondria from Nerve Cells via Nanotubes
Tumor cells can acquire energy from nerve cells by directly siphoning functional mitochondria through nanotubes, a process validated in human cancer tissue and observed across various cancer types, including breast and prostate cancer. This 'energy theft' provides cancer cells with a metabolic advantage, enhancing their survival and proliferation, particularly during metastasis.
Researchers develop MitoTRACER to identify cancer cells absorbing neuronal mitochondria
Researchers have developed a method called MitoTRACER to identify cancer cells that have absorbed mitochondria from nerve cells, enabling them to gain a metabolic advantage for spread. In mouse models of breast cancer, these mitochondria-receiving cells were found in higher numbers at metastatic sites, indicating a significant role for neuronal mitochondria in cancer progression.
Cancer Cells Acquire Mitochondria from Nerve and Immune Cells via Nanotubes
Cancer cells have been found to acquire mitochondria not only from nerve cells but also from immune cells, specifically T cells, through the formation of nanotubes. This highlights a broader mechanism by which cancer cells exploit their microenvironment to enhance survival and proliferation. Researchers are exploring these multifaceted strategies for energy acquisition, including 'energy waves' on cell membranes, which may offer new avenues for cancer staging and drug targeting.

Researchers discover breast cancer cells steal mitochondria from neurons to fuel metastasis
Researchers discovered that breast cancer cells can steal mitochondria from neurons to fuel their metastasis, leading to increased ATP content and greater metastatic capacity. This mechanism involves intimate physical contacts between neurons and cancer cells, facilitating the transfer of these energy-producing organelles. Blocking nerves in primary tumors reduced this mitochondria transfer, suggesting a potential therapeutic target.
