Metastatic dissemination is of poor prognosis for cancer patients. When exploring glucose metabolism in metastatic progenitor cells, we recently found that several different dysfunctions sharing the ability of inducing mitochondrial superoxide production also promote tumor metastasis. Selective targeting of mitochondrial superoxide prevented spontaneous metastasis in mice, opening a new avenue for therapy.
