Enhancer-promoter association determines cell specificity in mouse pluripotent cells
Enhancer-promoter association is emerging as a common pattern to determine gene function in eukaryotes. However, it remains as an uncultivated land on how its diversity influences gene expression. In this study, we select three defined Sox2 associated enhancers, representing different distal interaction categories, to further explore its biological effects. We construct three enhancer-knock-out cells via CRISPR/Cas9 system in mouse embryonic stem cells. With multiple-level evidences, we realize these associations carried out various biological features. Embryonic cell specific association determines cell proliferation and cell cycle and also involves in cardiac function, which has been validated in vivo. On the other hand, the common or indirect association prefers to regulate cell metabolic process and nerve development in cell function. Our study will enable an alternative way for gene spatiotemporal regulation study and advance our understanding of its diversity since first described decades ago.
