Apcdd1 regulates expression of both positive and negative targets of BMP signaling in Xenopus embryos. In situ hybridization of morpholino-depleted (A1MO), or Apcdd1 overexpressing embryos. Embryos were injected at the 4-cell stage dorsally (A-C, double in situ hybridization for chordin and LacZ RNA as injection marker, in red), or 1 cell stage (D–R). Control embryos were injected solely with LacZ RNA (1 ng). A-F. Spemann organizer genes: chordin is not affected by apcdd1 depletion (B) (n = 18 embryos), but inhibited by apcdd1 RNA (A1 RNA) overexpression (n = 23 embryos), consistent with the inhibition of the maternal, dorsal Wnt pathway; gsc is unaffected by either treatment (n = 15 and n = 12 embryos, respectively, E, F). G-L. The ventral marker and BMP target sizzled is expanded by Apcdd1 depletion (n = 23, I, J), and restored by expression of a MO-resistant apcdd1 RNA (n = 21 embryos, K, L). M-R. The early neural marker and negative BMP target sox2 is inhibited by Apcdd1 depletion (n = 27 embryos, O, P, arrows in O indicate a hole in the ventral expression pattern), and partially restored by expression of Apcdd1 RNA (n = 17 embryos, Q, R). |
