dtx1 expression is upregulated in Notch-deficient embryos. a The expression of dtx1 was analyzed in mib ta52b homozygous mutants and wild-type siblings through in situ hybridization. The stages are shown in the bottom left corner. Embryos were produced by crossing the parents with heterozygous mutant genotype. Embryos at 8 hpf, 10 hpf, and 16 hpf stages were mixed genotypes containing heterozygous mib ta52b mutation, homozygous mib ta52b mutation, and wild-type mib, and they were grouped according to the substantial difference in dtx1 expression. The results indicate that approximately 75 % of wild-type and heterozygous mib ta52b siblings had unaltered dtx1 expression, whereas approximately 25 % of homozygous mib ta52b mutants had increased dtx1 expression. Embryos at 24 hpf and 48 hpf were grouped according the morphological defects that only appeared in mib ta52b homozygous mutants. c. DAPT treatment was performed at different time points, and the embryos were harvested at different stages as indicated; the results show that DAPT treatment caused upregulation of dtx1 expression. b and d The results of in situ hybridization in a and c were quantitatively confirmed using qPCR analysis, respectively. *, P < 0.05
