Histone crotonylation is implicated in transcriptional regulation. Here, the authors perform genome-wide mapping of histone crotonylation in mouse and human early embryos. Suppression of histone crotonylation results in developmental arrest at 2-cell stage due to impaired transcriptional activity. Embryos from aged female mice exhibit diminished histone crotonylation, while sodium crotonate supplementation facilitates blastocyst formation.
