abstract = {Topologically associating domains (TADs) and chromatin
architectural loops impact promoter-enhancer interactions,
with CCCTC-binding factor (CTCF) defining TAD borders and
loop anchors. TAD boundaries and loops progressively
strengthen upon embryonic stem (ES) cell differentiation,
underscoring the importance of chromatin topology in
ontogeny. However, the mechanisms driving this process
remain unclear. Here we show a widespread increase in
CTCF-RNA-binding protein (RBP) interactions upon ES to
neural stem (NS) cell differentiation. While dispensable in
ES cells, RBPs reinforce CTCF-anchored chromatin topology in
NS cells. We identify Pantr1, a non-coding RNA, as a key
facilitator of CTCF-RBP interactions, promoting chromatin
maturation. Using acute CTCF degradation, we find that,
through its insulator function, CTCF helps maintain neuronal
gene silencing in NS cells by acting as a barrier to
untimely gene activation during development. Altogether, we
reveal a fundamental mechanism driving developmentally
linked chromatin structural consolidation and the
contribution of this process to the control of gene
expression in differentiation.},
