Fig. 4

Both of the major ENS neuronal subtypes are reduced in uhrf1 mutants. Confocal images of dissected intestines from wildtypes (A,C,E,G) and uhrf1 mutants (B,D,F,H) stained for expression of the pan-neuronal marker Elavl, and either nNOS or 5-HT. In both proximal (B,F) and distal (D,H) intestine, uhrf1 mutants have fewer enteric neurons than wildtype siblings at 5 dpf (proximal A,E; distal C,G) as quantified in (I). Both nNOS and 5-HT expressing ENS neuronal subtypes show similar reductions at 5 dpf [Elavl (green), nNOS or 5-HT (magenta)] as quantified in (J,K). Arrows point to examples of nNOS or 5-HT positive neurons. (I) Quantification of Elavl positive cells per 200 μm of proximal or distal intestine in wildtype (blue) or mutant (red) [wildtype n = 30 (proximal), n = 29 (distal); uhrf1−/− n = 29 (proximal), n = 30 (distal)]. (J–K) Quantification of Elavl and nNOS (J) and 5-HT (K) positive cells per 200 μm proximal or distal intestine in wildtype (blue) and mutant (red) [nNOS: wildtype n = 11 (proximal), n = 15 (distal); uhrf1−/− n = 17 (proximal), n = 17 (distal); 5-HT: wildtype n = 17 (proximal), n = 14 (distal); uhrf1−/− n = 15 (proximal), n = 13 (distal)]. Asterisk in B indicates autofluorescent background common to uhrf1 mutant intestines. Scale bar = 50 μm in A-H. Unpaired t-test: **** = p < 0.0001; ** = p < 0.01.
