There are many ways in which cells may not adequately behave or respond to their environment, and the molecular mechanisms leading to these defects are as diverse as they are many. In this review, we report on how spatial chromatin organization contributes to the proper expression of genes, relating how CTCF — one of its main architects — contributes to gene regulation. We also touch on the emerging role of long noncoding RNAs in shaping chromatin organization and activity. The HOX gene clusters have been used as paradigm in the study of various biological pathways, and the overview we provide gives emphasis to what research on these loci has revealed about chromatin architecture and its regulation in the control of gene expression.
