UAS regulatory sequences drive expression of an artificial microRNA (shRNA) targeting otu.
egg chamber, with Scer\GAL4VP16.nanos.UTR, Scer\GAL4VP16.otu, Scer\GAL4nanos.PG
Expression of otudsRNA.shRNA.Scer\UAS under the control of all three of the drivers Scer\GAL4otu.T:Hsim\VP16, Scer\GAL4nos.PG and Scer\GAL4nos.UTR.T:Hsim\VP16 results in a tumorous egg chamber phenotype.
