<i>Nom1</i> expression in the developing zebrafish.

<p>(A–D) Lateral views, anterior to the left. (E, F) Dorsal views, anterior to the top. (A) <i>nom1</i> has a strong maternal expression at 4-cell stage. (B–C) Non-specific ubiquitous <i>nom1</i> expression is evident at 10-somite stage and 1 dpf. (D, E) At 2 dpf, <i>nom1</i> expression in brain and liver is more apparent. (F) In addition to brain, <i>nom1</i> is strongly expressed in pancreas and weakly in intestine at 3 dpf. (G) RT-PCR analysis shows that <i>nom1</i> transcript is present at all embryonic stages.
