vas regulatory elements drive expression of an RNAi-resistant (coding sequence contains silent mutations so that it is no longer recognised by Tm1dsRNA.shRNA2.UAS) Tm1-C isoform tagged with EGFP.
The delocalization of the axis-determination factor osk mRNA characteristic for egg chambers expressing Tm1dsRNA.shRNA2.Scer\UAS under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 is rescued by co-expression of Tm1vas.C.RNAi-res.T:Avic\GFP-EGFP.
