Beyond The Disease, May 4, 2026

For the first at a major cancer conference, mitochondria were the subject of a crucial and well-attended session on how cancers actively recruit and transfer mitochondria into the fast growth operations. MitoWorld’s Alex Sercel and Gordon Freedman report on the session led by Yosuke Togashi, Okayama University, with panel members Simon Grelet, University of South Alabama and Luca, Gattinoni, University of Regensburg.

A recent paper in Cancer Letters by a multi-institute research team led by Francisca Alcayaga-Miranda, with Nicolás Georges-Calderón as first author, showed that melanoma cells release abnormal mitochondria into the extracellular compartment. Their findings describe a novel tumor-intrinsic mitochondrial quality control mechanism and also point to possible biomarkers for the disease.

Transplantation of healthy mitochondria has been proposed as a treatment for several serious diseases, but the methodology for accomplishing this has been missing. Recently, a research team, led by Botond Roska, developed a system for transplanting mitochondria to specific cell types. Their MitoCatch system is an exciting advance in harnessing mitochondria in therapies. The results were published in Nature.

In Glutathione, Mitochondria and Breast Cancer Metastasis, MitoWorld editor Gary Howard describes a recent paper in Cancer Discovery by a research team led by Kivanç Birsoy. Comparing the metabolics of normal and breast cancer cells, they found that metastasis of the cancer cells relied on mitochondrial glutathione. This discovery provides insights into the process of metastasis and implicates glutathione as a potential therapeutic target for breast cancer.

A paper published in Science Advances by a multi-institute research team describes a unique mechanism in mitochondria that might be a therapeutic target in patients with acute myeloid leukemia. The team was led by Kelsey H. Fisher-Wellman.
