Identifying the mechanism of cancer progression by cell-cell communication

Mitochondrial function is frequently impaired in human cancers; however, the mechanism by which mitochondrial defect contributes to tumor growth and progression is not known. Using the Drosophila genetic mosaic technique, Igaki and colleagues found that defects in mitochondrial function cooperate with oncogenic Ras activation to induce tumor progression and metastasis of surrounding benign tumors through the secretion of Unpaired (an IL-6 homolog) and Wingless (a Wnt homolog).
