Expression of Hsap\TP53Scer\UAS.cPa under the control of Scer\GAL4GMR.PF results in greatly reduced eyes with a disruption in ommatidial structure. Ommatidia are fused and show a complete loss of bristles. Eye discs show extensive apoptosis. There are no detectable effects on cell cycle distribution or cell size in the eye disc compared to wild type.
