Some patterns of histone methylation are linked to human gene activation, and other patterns are linked to gene repression. By combining chromatin immunoprecipitation with new Solexa 1G sequencing technology, Artem Barski at the National Institutes of Health and colleagues from the University of California, Los Angeles, generated genome-wide maps for histone methylations and correlated methylation events with different levels of gene expression.1 The researchers saw differences in methy
