“…Steroid receptors belong to a class of ligand-activated nuclear receptors that include thyroid hormone, retinoic acid, retinoid X, and 15-deoxy-∆ 12,14 prostaglandin J2 receptors (Evans, 1988;Beato, 1989;Glass, 1994;Mangelsdorf et al, 1995). These receptors regulate gene transcription by binding to specific sites on DNA.…”
