The regulation of gene expression involves multiple levels of control, from those that are inheritable to those that are highly responsive to environmental changes. In this issue of Genes & Development, Dong and colleagues (pp. 1159-1173) demonstrate that the dynamically controlled immune response transcription factor NF-kappaB may, in fact, have a role in regulating heterochromatin and gene expression at large distances from its actual target sequences and genes.
基因表达的调控涉及多个层面的控制,从可遗传的层面到对环境变化高度敏感的层面。在本期《基因与发育》中,董及其同事(第1159 - 1173页)证明,动态控制的免疫反应转录因子NF-κB实际上可能在远离其实际靶序列和基因的区域调控异染色质和基因表达。
