Histone acetylase inhibitor curcumin impairs mouse spermiogenesis-an in vitro study.

ABSTRACT: In the previous study, we unraveled the unique "erasure strategy" during the mouse spermiogenesis. Chromatin associated proteins sequentially disassociated from the spermatid chromosome, which led to the termination of transcription in elongating spermatids. By this process, a relatively naïve paternal chromatin was generated, which might be essential for the zygotic development. We supposed the regulation of histone acetylation played an important role throughout this "erasure" process. In order to verify this hypothesis, we treated mouse spermatids in vitro by histone acetylase (HAT) inhibitor Curcumin. Our results showed an inhibiting effect of Curcumin on the growth of germ cell line in a dose-dependent manner. Accordingly, the apoptosis of primary haploid spermtids was increased by Cu
