Mini Review
Chromatin Organization and Transcriptional Regulation at TADs and Loops Depleted Pachytene Stage during Spermatogenesis
Author(s): Zhengyu Luo and Xiaoyuan Song*
In mammals, high-order chromatin structures are reorganized during spermatogenesis. Topologically Associating
Domains (TADs) and chromatin loops are almost lost at the pachytene stage while CTCF and cohesion are still
bound on pachytene chromatin, and the promoters and enhancers on pachytene chromatin remain open. The fact
that pachytene chromatin is actively transcribed when TADs and chromatin loops are lost indicates that gene
transcriptional regulation at pachytene stage can be independent of TADs and chromatin loops. TADs and
chromatin loops loss is also found in CTCF and cohesion acute degraded cells in vitro. In this review, we discuss the
reorganized chromatin organization during spermatogenesis, especially at pachytene stage. We also discuss recent
progress in our understanding about fine-scale chromatin structures beyond TADs and chromatin loops and their.. View More»
