3D model of amphioxus steroid receptor complexed with estradiol [PDF]

open access: yes, 2009
The origins of signaling by vertebrate steroids are not fully understood. An important advance was the report that an estrogen-binding steroid receptor [SR] is present in amphioxus, a basal chordate with a similar body plan as vertebrates.

An optimized protocol with a stepwise approach to identify specific nuclear receptor ligands from cultured mammalian cells

open access: yesSTAR Protocols, 2021
Summary: Here, we describe an optimized protocol to identify specific nuclear receptor ligands. First, to rule out any compound interference with luciferase activity per se, we describe an in vitro assay assessing potential inhibition or activation of ...

Pregnane X receptor and constitutive androstane receptor modulate differently CYP3A-mediated metabolism in earlyand late-stage cholestasis [PDF]

open access: yes, 2017
AIM: To ascertain whether cholestasis affects the expression of two CYP3A isoforms (CYP3A1 and CYP3A2) and of pregnane X receptor (PXR) and constitutive androstane receptor (CAR).
