E.fanci RNAi#1 adult rectum after I-Cre. F.blm RNAi#1 adult rectum after I-Cre. Papillae false-colored green, DNA in purple in C-F. G.Number PH3+ micronuclei +/− I-Cre in WT vs. fanciRNAi#1 and fanciRNAi#2. Yellow bars= mean. From N=9-27 animals/condition, multiple replicates. H,I.Survival of fanci RNAi#1 adults without (blue) or with (red) I-Cre expression, plotted over time for the indicated diet conditions. Bars= standard error. Each genotype/condition represents 3 replicates with 10 animals/replicate. DAPI=DNA in all images. White scale bar=50μm, yellow scale bar=5μm.
