Dnmt3bb.1is necessary for hematopoietic gene expression.

(a,b) Transmitted light images of 72 hpf control (a) and dnmt3bb.1y258 (b) mutant zebrafish, showing absence of developmental delay or gross morphological abnormalities in dnmt3bb.1y258 mutants. (c-h) Whole mount in situ hybridization of 36 hpf (c,d), 72 hpf (e,f) and 96 hpf (g,h) wild type (WT) sibling (c,e,g) or dnmt3bb.1y258 (d,f,h) mutant animals, probed for cmyb. Cmyb is expressed in dnmt3bb.1 mutant at 36 hpf (arrows) but this expression is strongly reduced by 72 and 96 hpf (arrowheads). (i-l) Whole mount in situ hybridization of 72 hpf tails probed for l-plastin (i,j) and 5 dpf heads probed for rag1 (k,l) from WT sibling (i,k) or dnmt3bb.1 (j,l) mutant animals. Expression of both l-plastin and rag1 is present in controls (arrows) but strongly reduced in dnmt3bb.1 mutant animals (arrowheads). (m) Quantitative RT-PCR analysis of cmyb transcript levels in control (blue columns) or dnmt3bb.1 (red columns) morpholino injected animals at 36, 48, and 72 hpf. Transcript levels are normalized to the reference gene elf1α and to levels in 36 hpf control morphants. (n) Quantitative RT-PCR analysis of 3 dpf l-plastin and 5 dpf rag1transcript levels in control (blue columns) or dnmt3bb.1 (red columns) morpholino-injected animals. Transcript levels are normalized to the reference gene elf1α and to levels in controls. All graphs in panels i and j show mean ± SEM, are representative of three biological replicates. Scale bars = 150 µm in a,b, 50 µm in c,d, 100 µm in e-l.
