Adult Wing Precursor Imaginal Cells of Drosophila melanogaster Absence of Chinmo in imaginal cells suppresses wing growth (left) compared to control wing precursor tissue (middle), while overexpression of the Chinmo gene induces tissue overgrowth, as occurs in processes tumors (right). Credit: IBE Researchers discover Chimno, the gene responsible for the juvenile stage in insects. This gene is present in mammals and could play a key role in cancerous processes. The study, which was published in the journal eLife and led by the Institute for Evolutionary Biology (IBE, CSIC-UPF) and the IRB Barcelona, has revealed that the Chinmo gene is responsible...
