Structural Basis for Cholesterol Transport-like Activity of the Hedgehog Receptor Patched.
Yunxiao Zhang,David Bulkley,Yao Xin,Kelsey J. Roberts,Daniel Asarnow,Ashutosh Sharma,Benjamin R. Myers,Wonhwa Cho,Yifan Cheng,Philip A. Beachy +9 more
TL;DR: Cholesterol activity in the inner leaflet of the plasma membrane is reduced by PTCH1 expression but rapidly restored by Hedgehog stimulation, suggesting thatPTCH1 regulates Smoothened by controlling cholesterol availability.

Smoothened stimulation by membrane sterols drives Hedgehog pathway activity
Ishan Deshpande,Jiahao Liang,Danielle S. Hedeen,Kelsey J. Roberts,Yunxiao Zhang,Betty Ha,Naomi R. Latorraca,Bryan Faust,Ron O. Dror,Philip A. Beachy,Benjamin R. Myers,Benjamin R. Myers,Aashish Manglik +12 more
TL;DR: The crystal structure of active mouse SMO in complex with the SAG21k agonist and a stabilizing intracellular binding nanobody reveals the structural basis of SMO regulation by PTCH1, and suggests a strategy for overcoming clinical resistance to SMO inhibitors.

The Stromal Niche for Epithelial Stem Cells: A Template for Regeneration and a Brake on Malignancy
TL;DR: Understanding and therapeutic harnessing of the role of stroma in cancer restraint may hinge on knowledge of the signaling programs elaborated by the stromal niche.

Hedgehog pathway activation through nanobody-mediated conformational blockade of the Patched sterol conduit.
Yunxiao Zhang,Wan Jin Lu,David Bulkley,Jiahao Liang,Arthur Ralko,Shuo Han,Kelsey J. Roberts,Li A,Wonhwa Cho,Yifan Cheng,Yifan Cheng,Aashish Manglik,Philip A. Beachy +12 more
TL;DR: An agonist is developed, a conformation-specific nanobody that potentially targets the conformational changes of the Hedgehog receptor Patched1 and potently activates the pathway in vivo, facilitating mechanistic studies of Hedgehog pathway activation and the engineering of pathway activating agents for therapeutic use.

Structural basis for cholesterol transport-like activity of the Hedgehog receptor Patched
Yunxiao Zhang,David Bulkley,Kelsey J. Roberts,Yao Xin,Daniel Asarnow,Ashutosh Sharma,Benjamin R. Myers,Wonhwa Cho,Yifan Cheng,Philip A. Beachy +9 more
TL;DR: Patched expression indeed reduces cholesterol activity in the inner leaflet of the plasma membrane, in a manner antagonized by Hedgehog stimulation and with implications for regulation of Smoothened.
