Inactivation of p16 in Human Mammary Epithelial Cells by CpG Island Methylation
1 Apr 1998
Abstract excerpt
Proliferation of human mammary epithelial cells (HMEC) is limited to a few passages in culture due to an arrest in G1 termed selection or mortality stage 0, M0. A small number of cells spontaneously escape M0, continue to proliferate in culture, and then enter a second mortality stage, M1, at which they senesce. Evidence that M0 involves the Rb pathway comes from the observation that expression of human...
