Abstract

The physiological activities of estrogens are thought to be mediated by specific nuclear receptors, ERα and ERβ. However, certain tissues, such as the bone, that are highly responsive to estrogens only express a low level of these receptors. Starting from this apparent contradiction, we have evaluated the potentials of two related receptors ERRα and ERRβ to intervene in estrogen signaling. ERα, ERRα and ERRβ bind to and activate transcription through both the classical estrogen response element (ERE) and the SF-1 response element (SFRE). In contrast, ERβ DNA-binding and transcriptional activity is restricted to the ERE. Accordingly, the osteopontin gene promoter is stimulated through SFRE sequences, by ERRα as well as by ERα, but not by ERβ. Analysis of the cross-talk within the ER/ERR subgroup of nuclear receptors thus revealed common targets but also functional differences between the two ERs.
