Trithorax dependent changes in chromatin landscape at enhancer and promoter regions drive female puberty

Abstract

Before the onset of puberty, Polycomb proteins repress the expression of Kiss1 in KNDy neurons of the arcuate nucleus. Here, by CRISPR-Cas9-directed epigenome editing and RNAi, the authors show that coordinated action of Mll proteins at the Kiss1 promoter and enhancer is required for correct timing of puberty.
