Dorsal view of a pupa that carries hand-GFP and org-1-RFP and in which RNAi against Myc was induced ( org-1>>UAS-dsRNA-Myc). The video starts at late stage P3 and shows that knockdown of Myc abolishes dedifferentiation of the AMs into mononucleate myoblasts, suggesting a pivotal role of the Yki target Myc in the genetic control of the AM dedifferentiation process. Frame rate is 4 frames per second.
