The following issues are briefly addressed: (i) nucleosome and histone modifications by both the ATP-dependent remodeling complexes and the histone acetyltransferases and their roles in gene activation; (ii) competitive binding of histones and transcription factors on gene promoters, and transcription repression by nucleosomes; and (iii) influences of linker histone HI on gene regulation. Meanwhile, the significance and impact of these new research progresses, as well as issues worthwhile for further study are commented.展开更多
