Abstract
Aberrant activation of the Hedgehog (Hh) signaling pathway contributes to many forms of cancer. Primary cilia are Hh signal transduction centers. Two papers in a recent issue of Nature Medicine () show that mutating cilia can increase or reduce the rates of tumorigenesis depending on how the Hh pathway is disrupted. [Copyright &y& Elsevier]
