Knocking down the fwe lose-A and lose-B isoforms through expression of fwedsRNA.Scer\UAS.Shp under the control of Scer\GAL4GMR.PF results in an almost complete reduction in the physiological peripheral photoreceptor cell death seen in control pupae.
Expression of fwedsRNA.P\T.Scer\UAS.Shp in the loser cells under the control of Scer\GAL4αTub84B.PBb does not suppress the increase in wild type 'loser' clone splitting seen when cell competition is induced in the wing disc through generation of wild type clones in super-competitive MycαTub84B.PBb-expressing tissue.
