UASp regulatory sequences (in the pVALIUM22 vector) drive expression of an shRNA construct targeting Cdc42.
nurse cell, with Scer\GAL4VP16.osk
Expression of Cdc42dsRNA.shRNA.Scer\UAS.P\T under the control of Scer\GAL4osk.T:Hsim\VP16 results in defects in nurse cell dumping, resulting in an enlarged nurse cell compartment in egg chambers.
