Induced expression of FasC and reaper mRNAs in Drosophila cell transformants. Schneider cells transformed with either pMT-FasC (A, C, and D) or pMT-rpr (B and E) were treated with 0.5 mM CuSO4 for the indicated times. Poly(A)+ RNA (0.5 μg per lane) was resolved by electrophoresis on 1.5% agarose gels containing 2.2 M formaldehyde and was analyzed by Northern hybridization using the cDNA for the human Fas cytoplasmic region (A), reaper (B, C), and rp49 (D, E) as probes.
