Figure 6
ahctf1 heterozygosity restricts DNA replication in dox-treated TO(krasG12V)T/+ hepatocytes in the presence and absence of Tp53.
(a) Representative maximum intensity projection images of EdU incorporation (white puncta) into TO(krasG12V)T/+ livers of the indicated ahctf1 and tp53 genotypes. Scale bar 25 µm. (b) Quantification of the percentage of EdU-positive nuclei per Hoechst 33342-positive nuclei (n ≥ 25). (c) Impact of ahctf1 heterozygosity and homozygous tp53 mutation on liver volume in dox-treated TO(krasG12V)T/+ larvae (n ≥ 17). (d) RT-quantitative PCR (RT-qPCR) analysis of mRNA expression of the cell cycle regulators, cdkn1a and cdkn2a/b and (e) tp63 and tp73 expression in TO(krasG12V)T/+ micro-dissected livers of the indicated ahctf1 and tp53 genotypes (n = 3 biological replicates). Data are expressed as mean ± standard error of the mean (SEM). Significance was assessed using a one-way analysis of variation (ANOVA) with Tukey’s multiple comparisons test.
