Abstract

Cells possessing widely different physiological and morphological features have been treated with substances known to stimulate the differentiation of erythroleukemia cells. Only short fatty acids are capable of causing a hyperacetylation of the core histones and of enhancing the level of an H1-like protein in Chinese hamster ovary cells. While the time courses of a butyrate-mediated acetylation are similar for all cells, the maximum histone acetyl contents are much higher for the transformed cell of a given type. A withdrawal of butyrate rapidly (within 45 min) gives rise to a 'hypoacetylated state' for fibroblasts and transformed fibroblast (epithelial) cells from which there is a slow recovery. Lymphoid cells, on the other hand, display a marked persistance of the highly acetylated forms of histone H4.
