Description
| - Background InformationA Polycomb (PcG) body is an orphan nuclear subcompartment characterised by accumulations of Polycomb repressive complex 1 (PRC1) proteins. However, seemingly contradictory reports have appeared that describe the PcG bodies either as protein-based bodies in the interchromatin compartment or chromatin domains. In this respect, molecular crowding is an important factor for the assembly and stability of nuclear subcompartments. In order to settle this contradiction, crowding experiments, that represent a convenient model distinguishing between interchromatin and chromatin compartments, were carried out. ResultsIn sucrose-hypertonically induced crowding, we observed in U-2 OS cells that PcG bodies disappeared, but persisted as nuclear domains characterised by accumulations of DNA. This phenomenon was also observed in cells hypertonically treated with sorbitol and NaCl.
