Differences in Metabolic Programming Define the Site of Breast Cancer Cell Metastasis

Although metabolic reprogramming is a hallmark of oncogenic transformation and growth of primary tumor cells, little is known about how metabolic alterations impact metastasis. In this issue of Cell Metabolism, Dupuy et al. (2015) show that primary breast cancer cells display metabolic heterogeneity, and that their distinct metabolic programs define their sites of metastasis
