Abstract:
Epidermal morphogenesis is a complex process that culminates in the formation of a barrier that protects the organism from environmental substances and dehydration. p63, a transcription factor, is essential for normal epidermal morphogenesis as demonstrated by the failure of mice lacking p63 expression to develop an epidermis. However, since two independently generated p63(-/-) mouse models displayed different phenotypes, the role of p63 in epidermal morphogenesis has remained controversial. Furthermore, the tumor susceptibility phenotypes of both p63(-/-) mouse models were strikingly different. In this review, we discuss these conflicting findings and provide evidence for various roles of p63 in the epidermis under normal and pathological conditions.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
