UAS regulatory sequences drive expression of an artificial microRNA (shRNA) targeting bam.
egg chamber, with Scer\GAL4VP16.nanos.UTR, Scer\GAL4VP16.otu, Scer\GAL4nanos.PG
Expression of bamdsRNA.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.
