Nuclear Orphan Receptors Control Cholesterol Catabolism [PDF]

open access: yesCell, 1999
The multiple roles of metabolites and nuclear orphan receptors in regulating cholesterol homeostasis are summarized in Figure 3Figure 3. A complex interplay of intermediates and transcription factors serves to regulate the expression of dozens of genes, all in an attempt to control the levels of potentially toxic but essential hydrophobic molecules ...

NR4A Orphan Nuclear Receptors in Cardiovascular Biology. [PDF]

open access: yesDrug Discov Today Dis Mech, 2009
The NR4A orphan nuclear receptor subfamily is comprised of the highly homologous receptors Nur77 (NR4A1), Nurr1 (NR4A2), and NOR1 (NR4A3). These evolutionarily conserved and ancient receptors function as ligand-independent transcription factors that regulate the expression of overlapping target genes. As early response genes, the basal expression level

Nuclear Receptors: Lonesome orphans [PDF]

open access: yesCurrent Biology, 1995
Nuclear receptors typically bind to DNA as homodimers or heterodimers, but increasing numbers of orphan receptors have been identified that bind DNA as monomers.

Nuclear Hormone Receptors and Their Ligands: Metabolites in Control of Transcription

open access: yesCells, 2020
Nuclear hormone receptors are a family of transcription factors regulated by small molecules derived from the endogenous metabolism or diet. There are forty-eight nuclear hormone receptors in the human genome, twenty of which are still orphans.

Small Heterodimer Partner and Innate Immune Regulation [PDF]

open access: yesEndocrinology and Metabolism, 2016
The nuclear receptor superfamily consists of the steroid and non-steroid hormone receptors and the orphan nuclear receptors. Small heterodimer partner (SHP) is an orphan family nuclear receptor that plays an essential role in the regulation of glucose ...

CXR, a chicken xenobiotic-sensing orphan nuclear receptor, is related to both mammalian pregnane X receptor (PXR) and constitutive androstane receptor (CAR) [PDF]

open access: yes, 2000
Nuclear receptors constitute a large family of ligand-modulated transcription factors that mediate cellular responses to small lipophilic molecules, including steroids, retinoids, fatty acids, and exogenous ligands. Orphan nuclear receptors with no known

Identification of an endogenous ligand bound to a native orphan nuclear receptor. [PDF]

open access: yesPLoS ONE, 2009
Orphan nuclear receptors have been instrumental in identifying novel signaling pathways and therapeutic targets. However, identification of ligands for these receptors has often been based on random compound screens or other biased approaches.
