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. WebAbstract. SummaryRecent findings indicate that mammalian Sonic hedgehog (Shh) signal transduction occurs within primary cilia, although the cell biological mechanisms underlying both Shh signaling and ciliogenesis have not been fully elucidated. We show that an uncharacterized TBC domain-containing protein, Broad-minded (Bromi), is required for ...

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, … WebPrimary cilia are antenna-like cell structures that protrude in a single copy from the surface of most vertebrate cell types to detect extracellular cues that regulate embryonic …
WebSonic hedgehog protein (SHH) is encoded for by the SHH gene. The protein is named after the character Sonic the Hedgehog.. This signaling molecule is key in regulating embryonic morphogenesis in all animals. SHH controls organogenesis and the organization of the central nervous system, limbs, digits and many other parts of the body. Sonic hedgehog is … WebApr 4, 2012 · Primary cilia are nearly ubiquitous, at least in vertebrate cells, and it has become apparent that they play an essential role in the intracellular transduction of a range of stimuli. Most notable among these is Sonic Hedgehog. In this article we briefly summarize the structure and biogenesis of primary cilia.
WebSep 1, 2012 · Primary cilia and graded Sonic Hedgehog signaling Primary cilia and graded Sonic Hedgehog signaling Sasai, Noriaki; Briscoe, James 2012-09-01 00:00:00 Cilia are evolutionary‐conserved microtubule‐containing organelles protruding from the surface of cells. They are classified into two types—primary and motile cilia. WebJan 3, 2024 · ARL13B is a regulatory GTPase highly enriched in cilia. Complete loss of Arl13b disrupts cilia architecture, protein trafficking and Sonic hedgehog signaling. To determine whether ARL13B is required within cilia, we knocked in a cilia-excluded variant of ARL13B (V358A) and showed it retains all known biochemical function. We found that …
