SCRIB and neoplasm: In the second model, the tumour is induced via the QF2-QUAS mediated overexpression of RasV12 and scrib RNAi (Fig. 1A) in the eye, allowing us to knockdown or overexpress genes of interest in the muscles of tumour-bearing animals using drivers such as MhcGAL4 or Mef2GAL4 (Fig. 1A).
