Ntl Regulates wnt8 and wnt3a Expression without Intervening Protein Synthesis (A-F) The expression of wnt8 and (G-J) wnt3a in control EtOH-treated or dex-treated embryos injected with ntl-GR mRNA. (B) Continuous treatment with dex until shield stage increased wnt8 expression compared to (A) controls. (C-F) Chx treatment at shield stage followed by dex treatment for 1 or 2 hr also increased wnt8 expression. (G-J) Chx treatment at 75% epiboly followed by 2 hr of dex treatment increased wnt3a expression. Control embryos were treated with EtOH (A) or EtOH plus chx (C, E, G, and I). (A)-(H) are ventral views, animal pole at top; (I) and (J) are vegetal views. |
