Abstract:
The hedgehog pathway, initially discovered in Drosophila by two Nobel laureates, Dr. Eric Wieschaus and Dr. Christiane Nüsslein-Volhard, is a major regulator for cell differentiation, tissue polarity, and cell proliferation. Studies from many laboratories--including ours--reveal activation of this pathway in most basal cell carcinomas and nearly one third of extracutaneous human cancers, including medulloblastomas and gastrointestinal and prostate cancers. Even more exciting is the discovery and synthesis of specific signaling antagonists for the hedgehog pathway, which have significant clinical implications in novel cancer therapeutics. This review discusses the current understanding of the hedgehog signaling pathway and its activation in human cancers. It also discusses putative and confirmed signaling antagonists and their perspectives in therapeutic applications.

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...
