UTX Regulates Human Neural Differentiation and Dendritic Morphology by Resolving Bivalent Promoters.

ABSTRACT: UTX, a H3K27me3 demethylase, plays an important role in mouse brain development. However, so little is known about the function of UTX in human neural differentiation and dendritic morphology. In this study, we generated UTX-null human embryonic stem cells using CRISPR/Cas9, and differentiated them into neural progenitor cells and neurons to investigate the effects of UTX loss of function on human neural development. The results showed that the number of differentiated neurons significantly reduced after loss of UTX, and that the dendritic morphology of UTX KO neurons tended to be simplified. The electrophysiological recordings showed that most of the UTX KO neurons were immature. Finally, RNA sequencing identified dozens of differentially expressed genes involved in neural differentiation
