Mutations in GRK2 cause Jeune syndrome by impairing Hedgehog and canonical Wnt signaling

EMBO Molecular Medicine, 2020
Mutations in genes affecting primary cilia cause ciliopathies, a diverse group of disorders often affecting skeletal development. This includes Jeune syndrome or asphyxiating thoracic dystrophy (ATD), an autosomal recessive skeletal disorder.

A novel site comes into sight

eLife, 2013
Oxysterols modulate the Hedgehog signalling pathway by binding a novel site on the membrane protein Smoothened, which may offer new options for the treatment of cancers linked to this pathway.

A Smo/Gli multitarget hedgehog pathway inhibitor impairs tumor growth [PDF]

, 2019
Pharmacological Hedgehog (Hh) pathway inhibition has emerged as a valuable anticancer strategy. A number of small molecules able to block the pathway at the upstream receptor Smoothened (Smo) or the downstream effector glioma-associated oncogene 1 (Gli1)

Smoothened agonist sterosome immobilized hybrid scaffold for bone regeneration

Science Advances, 2020
Hybrid scaffold with smoothened agonist sterosomes is engineered as a useful bone graft device for more efficacious bone healing. Biomaterial delivery of bioactive agents and manipulation of stem cell fate are an attractive approach to promote tissue ...

Data‐driven performance metrics for neural network learning

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Cholesterol accessibility at the ciliary membrane controls hedgehog signaling

eLife, 2019
Previously we proposed that transmission of the hedgehog signal across the plasma membrane by Smoothened is triggered by its interaction with cholesterol (Luchetti et al., 2016).

Developmental and Repairing Production of Myelin: The Role of Hedgehog Signaling

Frontiers in Cellular Neuroscience, 2018
Since the discovery of its role as a morphogen directing ventral patterning of the spinal cord, the secreted protein Sonic Hedgehog (Shh) has been implicated in a wide array of events contributing to the development, maintenance and repair of the central

Synergistic inhibition of the Hedgehog pathway by newly designed Smo and Gli antagonists bearing the isoflavone scaffold [PDF]

, 2018
Aberrant activation of the Hedgehog (Hh) pathway is responsible for the onset and progression of several malignancies. Small molecules able to block the pathway at the upstream receptor Smoothened (Smo) or the downstream effector Gli1 have thus emerged ...

Cholesterol activates the G-protein coupled receptor Smoothened to promote Hedgehog signaling

eLife, 2016
Cholesterol is necessary for the function of many G-protein coupled receptors (GPCRs). We find that cholesterol is not just necessary but also sufficient to activate signaling by the Hedgehog (Hh) pathway, a prominent cell-cell communication system in ...

Smoothened regulation in response to Hedgehog stimulation [PDF]

Frontiers in Biology, 2015
The Hedgehog (Hh) signaling pathway play critical roles in embryonic development and adult tissue homeostasis. A critical step in Hh signal transduction is how Hh receptor Patched (Ptc) inhibits the atypical G protein-coupled receptor Smoothened (Smo) in the absence of Hh and how this inhibition is release by Hh stimulation.
