BACKGROUND: The interplay between 3D genomic structure and transposable elements (TE) in regulating cell state-specific gene expression program is largely unknown. Here, we explore the utilization of TE-derived enhancers in naïve and expanded pluripotent states by integrative analysis of genome-wide Hi-C-defined enhancer interactions, H3K27ac HiChIP profiling and CRISPR-guided TE proteomics landscape. RESULTS: We find that short interspersed nuclear elements (SINEs) are the more involved TEs in the active chromatin and 3D genome architecture. In particular, mammalian-wide interspersed repeat (MIR), a SINE family member, is highly associated with naïve-specific genomic interactions compared to the expanded state. Primarily, in the naïve pluripotent state, MIR enhancer is co-opted by ESRRB for naïve-specific gene expression program. This ESRRB and MIR enhancer interaction is crucial for the formation of loops that build a network of enhancers and super-enhancers regulating pluripotency genes. We demonstrate that loss of a ESRRB-bound MIR enhancer impairs self-renewal. We also find that MIR is co-bound by structural protein complex, ESRRB-YY1, in the naïve pluripotent state. CONCLUSIONS: Altogether, our study highlights the topological regulation of ESRRB on MIR in the naïve potency state.
