Polycomb group proteins in cell cycle progression and cancer

Cell Cycle. 2004 Apr;3(4):396-400. Epub 2004 Apr 1.

Abstract

Epigenetic deregulation of gene expression is emerging as key mechanism in tumorigenesis. Deregulated activity of the chromatin remodeling Polycomb Repressive Complex 2 (PRC2) has recently been shown to be a frequent event in human tumors. Here we discuss these findings and speculate on the role of the PRC2 complex in controlling gene expression during normal cellular proliferation and cancer development.
