Acute disruption of select steroid receptor coactivators prevents reproductive behavior in rats and unmasks genetic adaptation in knockout mice.

Estrogen (E) and progesterone exert profound influence on development and reproduction. In vitro, steroid receptor coactivators (SRCs) are nuclear proteins that interact with DNA-bound steroid receptors to potentiate their transcriptional efficiency. We examined the effects of antisense oligonucleotides to SRC-1, SRC-2, and SRC-3 on female sexual behavior and steroid receptor-mediated transcription.
