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
