This improvement did not result from a significant loss of tumor mass, as the tumor burden on day 6 AEL was similar between rasV12scrib1, rasV12scrib1kay3 and rasV12scrib1ets21cLONG RNAi clones, and we observed only a slight reduction of GFP-positive tissue upon ftz-f1 RNAi (Fig. 3C-F). This evidence concerns the gene NR5A1 and neoplasm.
