Expression of molecular markers for digestive organs and brain is reduced in the morha4/ha4 mutant. (A–B) The expression of dla was examined using whole-mount in situ hybridization at 3 dpf. All lateral views, anterior to the left. (C–J) The expression of fabp2, fabp10a, ptf1a, and ins was examined using whole-mount in situ hybridization at 3.5 dpf. All dorsal views, anterior to the top. Although the expression of dla, fabp2, and fabp10a was slightly reduced, the ptf1a expression was markdly reduced at 3 or 3.5 dpf in the morha4/ha4 mutants (A–H). In contrast, the ins expression in the morha4/ha4 mutant did not change at these developmental stages (I, J). Control larvae were sibling WT or morha4/+ larvae and had normal phenotypes.
