Hedgehog-GLI Signaling in Human Disease represents the first compilation of up-to-date reviews by top-level scientists in this important field of research. The chapters cover a wide spectrum of related interests, from the molecular bases of morphogen function, to human genetics to cancer research. The aim of the book is to disseminate information on this exciting field, to allow students, scientists and the public in general to gain access current information from research leaders and to provide a book that encompasses different aspects of research showing the fusion of basic research in model systems and medicine. This is a timely primer on how a system of cell communication, Hedgehog-GLI signaling, plays a critical role in human disease and thus provides the background for the development of novel and rational therapies.
