FIGURE 5.

Elovl1 knockdown suppresses lipid consumption in the yolk and lipid utilization in the swim bladder. Oil-Red-O staining was performed to visualize the neutral lipids in developing embryos at 4 and 5 dpf. Note that neutral lipids accumulate in the yolk (compare B with D) as well as on the surface of swim bladder epithelium (compare F and H) in MOelovl1-injected embryos. Embryos are presented in lateral views (A–D) with the anterior aspect to the left. Dissected swim bladders from the wild type and knockdown embryos are presented in dorsal views (E–H) with the anterior aspect to the left.
