The study uncovers a human-specific regulatory mechanism involving endogenous retroviruses (ERVs), particularly HERVK LTR5Hs, which influence gene expression and lineage specification during early human development, using a stem cell-based blastoid model. Repression of LTR5Hs impairs blastoid formation, alters lineage allocation, and affects the expression of key genes like ZNF729, a human-specific gene regulated by a nearby LTR5Hs insertion that is essential for blastoid formation and proliferation. The work highlights the evolutionary role of ERVs as enhancers shaping human-specific developmental features.

A recent study reveals that ancient viral DNA embedded in our genome, particularly the MER11 family of transposable elements, plays a significant role in regulating gene expression during early human development. Researchers developed a new classification method to better understand these elements and found that the youngest subfamily, MER11_G4, has a strong ability to activate gene expression and has evolved distinct regulatory functions, contributing to primate evolution.
