induces involution-related genes in HC11 cells and cooperates
with p53 in inducing apoptosis. The non-transformed mouse mammary epithelial
cell line HC11 was transiently transfected with constructs expressing the
indicated proteins, and harvested after 2 days. (A) Northern analysis of the
indicated genes in total RNA from representative samples are shown. (B) The
flow cytometric quantification of arrested (G1 DNA content) and (C) apoptotic
cells (sub-G1 DNA content) represents the means ± s.d. of six to eight
samples from three to four independent experiments.
