In many metazoans, germ cells are separated from somatic lineages early in development and maintain their identity throughout life. Here we show that a Polycomb group (PcG) component, Enhancer of Zeste [E(z)] H3K27me3-specific methyltransferase, maintains germline identity in Drosophila adult testes...

12 genome-wide microarrays to investigate the Tetrahymena thermophila gene expression changes in TRX1 and EZL2 gene knockout and hydroxyurea (HU) treatment conditions. For the TRR1 knockout (KO) condition, wild type (WT427) cells and TRX1 KO cells were cultured using 1XSPP, 30 degrees, 100 rpm shaki...

Formation of the blood from self-renewing hematopoietic stem cells to terminal lineages necessarily involves epigenomic modifications of the genome to control regulator and signature gene expression. By analysing the global expression profiles of hematopoietic stem cells (HSCs), in vivo differentiat...

Chromatin modifications have been implicated in the self-renewal and differentiation of embryonic stem cells (ESCs). However, the function of histone variant H2A.Z in ESCs remains unclear. We show that H2A.Z is highly enriched at promoters and enhancers and is required for both efficient self-renewa...
