Species-specific rewiring of definitive endoderm developmental gene activation via endogenous retroviruses through TET1-mediated demethylation

Transposable elements (TEs) are the major sources of lineage-specific genomic innovation and comprise nearly half of the human genome, but most of their functions remain unclear. Here, we identify that a series of endogenous retroviruses (ERVs), a TE subclass, regulate the transcriptome at the definitive endoderm stage with in vitro differentiation model from human embryonic stem cell. Notably, these ERVs perform as enhancers containing binding sites for critical transcription factors for endoderm lineage specification. Genome-wide methylation analysis shows most of these ERVs are derepressed by TET1-mediated DNA demethylation. LTR6B, a representative definitive endoderm activating ERV, contains binding sites for FOXA2 and GATA4 and governs the primate-specific expression of its neighboring developmental genes such as ERBB4 in definitive endoderm. Together, our study proposes evidence that recently evolved ERVs represent potent de novo developmental regulatory elements, which, in turn, fine-tune species-specific transcriptomes during endoderm and embryonic development.
