Fig. 3. daf-15 and let-363 metabolic defect. Fat accumulation was
assayed by Sudan black staining in L3 larvae grown at 20°C; daf-2
dauer larvae were formed constitutively at 25°C. (A) Wild-type N2, (B)
daf-2(e1370), (C) daf-15(m81), (D) let-363(h111),
(E) daf-16(mgDf47), (F) daf-16(mgDf47); daf-15(m81). All
mutants except for the daf-16 single mutant accumulate abnormally
high levels of fat relative to wild type. The entire experiment was performed
twice, with at least 30 animals observed each time. Fat accumulation in
daf-15(m81) and let-363(h111) was also confirmed by Nile red
staining (data not shown).
