摘要
Polycomb group(PcG)proteins were originally identified as suppressors of the homeotic genes in Drosophila[1],controlling segment identity during embryonic development.Then PcG proteins were found to participate in the regulation of various biologic processes,including cell cycle,apoptosis and tumor development[2].It is commonly accepted that the PcG proteins form two
