Biological Information

Background Information:

The estrogen-related receptors ERRα, ERRβ, and ERRγ form a subfamily of orphan nuclear receptors that share significant homology with the estrogen receptors ERα and ERβ to possess the potential to positively and negatively regulate estrogen responsiveness. The ER agonist diethylstilbestrol (DES) and the selective ER modulator (SERM) 4-hydroxytamoxifen (4-OHT) have been identified as ERR antagonists. The rational development of synthetic ligands on ERR targets may be useful in improving the treatment of menopause, metabolic disorders, osteoporosis, serum lipids, breast and other cancers.

Testing Information

Procedure Summary:

"Test compound and/or vehicle is incubated with the 2.5 nM‡ estrogen related receptor beta (ERRβ)-LBD and coactivator peptide for 1 hour at RT. Determination of the amount of complex formed is read spectrofluorimetrically at 520 nm/490 nm. Test compound-induced increase fluorescence by 50 percent or more (≥50%) relative to the 30 μM GSK4716 response indicates possible ERRβ receptor agonist activity. Test compound-induced inhibition of 10 μM GSK4716-induced fluorescence response by 50 percent or more (≥50%) indicates receptor antagonist activity.

Incubation:

1 hr at RT

Control Inhibitor:

4-Hydroxytamoxifen

Control Activator:

GSK4716

Criteria For Significance:

≥ 50% decrease in fluorescence relative to GSK4716 response, ≥ 50% increase in fluorescence relative to GSK4716 response

Test Concentration / Dose:

Compounds are screened at 10, 3, 1, 0.3, 0.1, 0.03, 0.01 and 0.003 μM

Test Sample Requirements:

75 μl of 10 mM stock or 1 mg (pre-weighed) powder (assuming FW ≦500 and purity 100%)
