Abstract

RORα and RORγ are expressed in human skin cells that produce the noncalcemic 20‐hydroxyvitamin D 3 [20(OH)D 3 ] and 20,23‐dihydroxyvitamin D 3 [20,23(OH) 2 D 3 ]. Chinese hamster ovary (CHO) cells stably expressing a Tet‐on RORα or RORγ expression vector and a ROR‐responsive element (RORE)‐LUC reporter, and a mammalian 2‐hybrid model examining the interaction between the ligand binding domain (LBD) of RORα or RORγ with an LBD‐interacting LXXLL‐peptide, were used to study ROR‐antagonist activities. These assays revealed that 20(OH)D 3 and 20,23(OH) 2 D 3 function as antagonists of RORα and RORγ. Moreover, 20(OH)D 3 inhibited the activation of the promoter of the Bmal1 and G6pase genes, targets of RORα, and 20(OH)D 3 and 20,23(OH) 2 D 3 inhibited Il17 promoter activity in Jurkat cells overexpressing RORα or RORγ. Molecular modeling using crystal structures of the LBDs of RORα and RORγ revealed docking scores for 20(OH)D 3 , 20, 23(OH) 2 D 3 and 1,25(OH) 2 D 3 similar to those of the natural ligands, predicting good binding to the receptor. Notably, 20(OH)D 3 , 20,23(OH) 2 D 3 , and 1,25(OH) 2 D 3 inhibited RORE‐mediated activation of a reporter in keratinocytes and melanoma cells and inhibited IL‐17 production by immune cells. Our study identifies a novel signaling pathway, in which 20(OH)D 3 and 20,23(OH) 2 D 3 act as antagonists or inverse agonists of RORα and RORγ, that opens new possibilities for local (skin) or systemic regulation.—Slominski, A.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
