Fetus Sound Stimulation: Cilia Memristor Effect of Signal Transduction
BACKGROUND This experimental study evaluates fetal middle cerebral artery (MCA) circulation after the defined prenatal acoustical stimulation (PAS) and the role of cilia in hearing and memory and could explain signal transduction and memory according to cilia optical-acoustical properties. METHODS PAS was performed twice on 119 no-risk term pregnancies. We analyzed fetal MCA circulation befor...
متن کاملThe Mammalian Cos2 Homolog Kif7 Plays an Essential Role in Modulating Hh Signal Transduction during Development
The Hedgehog (Hh) signaling pathway regulates development in animals ranging from flies to humans. Although its framework is conserved, differences in pathway components have been reported. A kinesin-like protein, Costal2 (Cos2), plays a central role in the Hh pathway in flies. Knockdown of a zebrafish homolog of Cos2, Kif7, results in ectopic Hh signaling, suggesting that Kif7 acts primarily a...
متن کاملMultisite interaction with Sufu regulates Ci/Gli activity through distinct mechanisms in Hh signal transduction.
The tumor suppressor protein Suppressor of fused (Sufu) plays a conserved role in the Hedgehog (Hh) signaling pathway by inhibiting Cubitus interruptus (Ci)/Glioma-associated oncogene homolog (Gli) transcription factors, but the molecular mechanism by which Sufu inhibits Ci/Gli activity remains poorly understood. Here we show that Sufu can bind Ci/Gli through a C-terminal Sufu-interacting site ...
متن کاملPlanarian Hh signaling regulates regeneration polarity and links Hh pathway evolution to cilia.
The Hedgehog (Hh) signaling pathway plays multiple essential roles during metazoan development, homeostasis, and disease. Although core protein components are highly conserved, the variations in Hh signal transduction mechanisms exhibited by existing model systems (Drosophila, fish, and mammals) are difficult to understand. We characterized the Hh pathway in planarians. Hh signaling is essentia...
متن کاملTransduction physiology of olfactory receptor cilia.
Electro-olfactograms (EOGs) evoked by 8 odorants from frog olfactory epithelia during ciliary regrowth and during epithelial regeneration were analyzed. During ciliary regrowth following detergent-induced ciliary removal, EOG amplitudes initially increase proportionately with ciliary length. EOGs reach maximal amplitudes after 2 days of growth, when cilia are 40 micron long. Therefore olfactory...
