Camptothecin-Induced Apoptosis Is Decreased in BAXA and BAXB Mutant Zebrafish, Related to Figure 1

(A) Global analysis without end-gap penalty of protein sequence homology between human BAK1 (transcripts 202 and 203), BAX (only major transcripts, alpha and beta) and zebrafish BAXA and BAXB. Prefix h, human; prefix zf, zebrafish. Although BAXB has been suggested to be the zebrafish functional equivalent of human BAK (Kratz et al., 2006), neither it nor BAXA had significant homology to either human BAK transcript. Identity (red) (%), similarity (%), (global/local score).

(B) Comparison of protein sequence homology between human BAX alpha and zebrafish BAXA. Relevant BH domains of BAX are showed in colored boxes.

(C) Representative inverted fluorescence images of 2 dpf larvae that are WT, BAXA mutant or BAXB mutant treated with camptothecin and incubated with acridine orange to detect apoptotic cells.

(D) Quantification of camptothecin-induced apoptosis (See STAR Methods) in WT, BAXA mutant or BAXB mutant fish from (C) in the area within red dashed line. ^∗p < 0.05; ^∗∗p < 0.01; ^∗∗∗p < 0.001 (one-way ANOVA with Tukey’s post-test). Representative of 3 independent experiments.
