Exposure of Drosophila melanogaster tissue culture cells to 37°C (heat shock) or to arsenite induces a severe deacetyl-ation of core histones and blocks the methylation of histone H3 and H4. Heat shock induces the methylation of histone H2b. These results are discussed in view of chromatin structure and function.
