Sonic hedgehog cilia

WebSep 26, 2024 · Primary cilia are antenna-like structures that develop on the surface of quiescent G 0 -phase cells and receive extracellular signals including sonic hedgehog (Shh) for embryogenesis and adult tissue homeostasis. In mammalian cells, cholesterol activates the seven-transmembrane protein Smoothened to transduce the Shh signal. WebThe sonic hedgehog signaling pathway is essential to the development and homeostasis of brain. Aberrant sonic hedgehog signaling is increased in refractory epileptic lesions and may involve the etiology of epilepsy. Thus, new inhibitors of Smoothened, a key signal transducer of this signaling pathway are urgently need for refractory epilepsy.

WebMar 20, 2024 · Hedgehog (Hh) signaling pathway plays an essential role during vertebrate embryonic development and tumorigenesis. It is already known that Sonic hedgehog (Shh) pathway is important for the evolution of radio and chemo-resistance of several types of tumors. Most of the brain tumors are resistant to chemotherapeutic drugs, consequently, … WebSep 2, 2008 · Previous studies suggested that primary cilia mediate sonic hedgehog (Shh) signaling. Here, we find that loss of ALNP cilia leads to abrogated Shh activity, increased cell cycle exit, and morphological abnormalities in ALNPs.
