Abstract
Acetylation of nucleosome core histones, which is positively correlated with transcriptional activity, is developmentally regulated in Xenopus. Here we have used the specific histone deacetylase (HDAC)-inhibitor trichostatin A (TSA) to induce precocious histone hyperacetylation in the early frog embryo in order to investigate the potential role of the endogenous changes in chromatin acetylation for the temporally programmed induction of skeletal myogenesis. We show that TSA-treatment (i) selectively blocked the transcriptional induction of the myoD gene, and (ii) severely reduced subsequent muscle differentiation. Both phenotypes required TSA application before gastrulation. This indicates that HDAC activity is required early for the formation of the frog embryonic musculature, apparently for the induction of the MyoD-dependent muscle cell lineage.
