RAR-specific pharmacological reagents affect expression of Tg(12XRARE-ef1a:gfp), while pharmacological reagents specific for other nuclear hormone receptors do not. (A) Untreated control embryo. (B) Ro41-5253, a RARα-specific antagonist, inhibits reporter expression. (C) AM580, a RARα-specific agonist, activates ectopic reporter expression. Arrows (ventral eye) and arrowheads (anterior spinal cord) in B and C indicate where restricted expression is normally found in an untreated embryo (A). (D) The pan-RXR agonist methoprene acid (Biomol.com) does not affect reporter expression. Agonists of (E) PPARα (GW7647), (F) PPARδ (GW0742), and (G) PPARγ (GW1929) do not activate the reporter. The pan-PPAR antagonist LY171883(H) and the PPARα specific antagonist GW6471 (I) do not inhibit reporter expression. All PPAR-related reagents were purchased from Sigma. All images are lateral views, with anterior up and dorsal to the right |
