Nuclear orphan receptor Nor-1 contributes to depressive behavior in the Wistar-Kyoto rat model of depression.

The current study explored the effects of prolonged antidepressant treatment on mRNA levels of two nuclear receptors in specific brain regions of an animal model of depression, the Wistar-Kyoto (WKY) rat. Both nuclear receptors have been implicated in the development or treatment of depression. The expression of nuclear orphan receptor-1 (Nor-1), a member of the NR4A nuclear orphan receptor family, is induced by electroconvulsive shock, an effective treatment for depression.
