Figure 4From: Deficiency of the p53/p63 target Perp alters mammary gland homeostasis and promotes cancerMany human breast cancer cell lines exhibit reduced Perp expression compared with untransformed cells. Western blot analysis of Perp levels in multiple human breast cancer cell lines and in untransformed human and mouse mammary epithelial cell lines (MCF10A and EpH4, respectively). Wild-type and Perp-/- mouse (msker) keratinocytes and normal human epidermal keratinocytes (NHEK) demonstrated that the antibody recognizes Perp. β-Actin served as a loading control.Back to article page
