2 is required for heart and gut LR patterning
in zebrafish. (A-D) Live 2-day-old control (A),
2 morphant
(B), Ncx4a morphant (C) and A23187-treated (D) embryos. (E-G)
2
morphants that exhibited normal (E), absent (F) or reversed (G) cardiac
looping after 2 days of development. Ventral view, with anterior to the top.
v, ventricle; a, atrium. (H-J) 2-day-old
2 morphants with normal
(H), straight (I) or reversed (J) positions of gut, liver and pancreas. Dorsal
view, with anterior to the top. li, liver; p, pancreas. (K) Bar chart
detailing the heart and gut laterality phenotypes of uninjected embryos and
those injected with CTL-MO,
2-MO,
2-SP-MO, Ncx4a-MO and
Ncx4a-SP-MO. The effects of
2-SP-MO and Ncx4a-SP-MO on RNA processing
are shown in the upper and lower panels, respectively, on the right.
