Fig. 4. Hdac4 is a key mediator of the Bap1-deficient phenotype.

Fig. 4

(A) Representative embryos injected at the one-cell stage with 7.5 ng of Bap1MO with or without 16 ng of a morpholino directed against Hdac4 (Hdac4MO) and analyzed at midneurula stage (stage 15, dorsal view, anterior to left) and early tail bud stage (stage 26, lateral view, anterior to left). (B) Summary of results at stages 15 and 26, showing substantial rescue of the Bap1-deficient phenotype with Hdac4MO. (C) Representative embryos treated as above and analyzed by WISH, demonstrating that failed induction of the indicated developmental genes in Bap1-deficient embryos is rescued by Hdac4MO. Caudal view, dorsal up. (D) ChIP–quantitative polymerase chain reaction (qPCR) for indicated gene promoters following ChIP for H3K27ac, confirming that failure to assemble H3K27ac at promoters in Bap1-deficient embryos can be rescued by depletion of Hdac4. Scale bars, 250 μm.
