Their works demonstrated that, in mouse embryonic stem cells (ESC), these regions essentially correspond to the most highly expressed genes, and to cis-regulatory sequences like super-enhancers, that belong to the active A chromosomal compartment. They include both cell type-specific genes, such as pluripotency genes in ESC, and housekeeping genes associated with nuclear bodies, such as histone and snRNA genes that are central components of Histone Locus Bodies and Cajal bodies. These results, which are in agreement with the recently proposed \u201cphase separation model\u201d for transcription control (Hnisz et al., 2017, Cell 169,13-23), suggest that nuclear bodies might play a central role in organizing the active chromosomal compartment in mammals.<img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-3734 aligncenter\" src=\"http:\/\/www.igmm.cnrs.fr\/wp-content\/uploads\/2018\/10\/HSR-seq-eng-450x273.jpg\" alt=\"\" width=\"450\" height=\"273\" srcset=\"https:\/\/www.igmm.cnrs.fr\/wp-content\/uploads\/2018\/10\/HSR-seq-eng-450x273.jpg 450w, https:\/\/www.igmm.cnrs.fr\/wp-content\/uploads\/2018\/10\/HSR-seq-eng.jpg 700w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>Baudement M-O., Cournac A., Court F., Seveno M., Parrinello H., Reynes C., Sabatier R., Bouschet T., Yi Z., Sallis S., Tancelin M., Rebouissou C., Cathala G., Lesne A., Mozziconacci* J., Journot* L. and Forn\u00e9* T. \u00ab High-salt Recovered Sequences are associated with the active chromosomal compartment and with large ribonucleoprotein complexes including nuclear bodies \u00bb.
