Note Loss of the Y chromosome from individual metaphases is common in metaphase cells from both PHAstimulated lymphocytes and spontaneously dividing bone marrow cells. The frequency of Y loss is greater in older men, and the size of the 45,X,-Y cell population probably increases gradually with advancing age. (In females, a corollary loss of one X chromosome also occurs with advancing age.) This...
Polycomb group (PcG) proteins form transcriptional repressor complexes with well-established functions during cell-fate determination. Yet, the mechanisms underlying their regulation remain poorly understood. Here, we extend the role of Polycomb complexes in the temporal control of neural progenitor cell (NPC) commitment by demonstrating that the PcG protein Ezh2 is necessary to prevent the pre...
