Kuzhandaivel A, Schultz SW, Alkhori L, Alenius M. Cilia-Mediated Hedgehog Signaling in Drosophila. Cell Rep. 2014 Apr 23. pii: S2211-1247(14)00249-6. PMID: 24768000.
From the abstract: "Cilia mediate Hedgehog (Hh) signaling in vertebrates and Hh deregulation results in several clinical manifestations, such as obesity, cognitive disabilities, developmental malformations, and various cancers. ... We demonstrate that several fundamental key aspects of the vertebrate cilia pathway ... are present in Drosophila. ... our data demonstrate that Hh signaling in Drosophila can be mediated by two pathways and that the ciliary Hh pathway is conserved from Drosophila to vertebrates."
