Spermatogonia presents well-defined compartment patterns and topological domains. However, chromosome occupancy and compartmentalization are highly re-arranged during prophase\u00a0I, with cohesins bound to active promoters in DNA loops out of the chromosomal axes. Compartment patterns re-emerge in round spermatids, where cohesin occupancy correlates with transcriptional activity of key developmental genes. The compact sperm genome contains compartments with actively transcribed genes but no fine-scale topological domains, concomitant with the presence of protamines. Overall, we demonstrate how genome-wide cohesin occupancy and transcriptional activity is associated with three-dimensional (3D) remodeling during spermatogenesis, ultimately reprogramming the genome for the next generation.<\/div>\n<\/div>\n<div>\u00a0<\/div>\n<div>\u00a0<\/div>\n<div>\u00a0<\/div>\n<div>\u00a0<\/div>\n<div>\u00a0<\/div>\n<div>\u00a0<\/div>\n","protected":false},"excerpt":{"rendered":"<p>ARTICLE| VOLUME 28, ISSUE 2, P352-367.E9, JULY 09, 2019 Covadonga Vara; Andreu Paytuv\u00ed-Gallart ; Yasmina Cuartero ;Paul D.
