EL0587	HOXA-AS	HOXA gene	RNA-DNA	regulation	We have investigated the intergenic, noncoding transcriptomes of mammalian HOX clusters. We show that "opposite strand transcription" from the intergenic spacer regions in the human HOXA cluster correlates with the activity state of adjacent HOXA genes. This noncoding transcription is regulated by the retinoic acid morphogen and follows the colinear activation pattern of the cluster. Opening of the cluster at sites of activation of intergenic transcripts is accompanied by changes in histone modifications and a loss of interaction with Polycomb group (PcG) repressive complexes.	17185360
