ΔNp63α-Mediated Activation of Bone Morphogenetic Protein Signaling Governs Stem Cell Activity and Plasticity in Normal and Malignant Mammary Epithelial Cells

16 Dec 2012

Abstract excerpt

Genetic analysis of TP63 indicates that ΔNp63 isoforms are required for preservation of regenerative stasis within diverse epithelial tissues. In squamous carcinomas, TP63 is commonly amplified, and ΔNp63α confers a potent survival advantage. Genome-wide occupancy studies show that ΔNp63 promotes bidirectional target gene regulation by binding more than 5,000 sites throughout the genome; however, the subset of...
