p63 maintains keratinocyte proliferative capacity through regulation of Skp2–p130 levels

Abstract excerpt

p63 is a master regulator of proliferation and differentiation in stratifying epithelia, and its expression is frequently altered in carcinogenesis. However, its role in maintaining proliferative capacity remains unclear. Here, we demonstrate that hypoproliferation and loss of differentiation in organotypic raft cultures of primary neonatal human foreskin keratinocytes (HFKs) depleted of the α and β isoforms of...
