Fig. 5. Regulation of en2 expression and ß-catenin stability by
PP2A:B56
in the neural ectoderm at stage 14. (A) RT-PCR showing that
en2 is reduced by PP2A:B56
morpholino at stage 14. (B-E)
Whole-mount in situ hybridization showing pax2.1 (B,C) and
XHR1 (D,E) are not reduced by PP2A:B56
morpholino injection at
stage 14. (B,D) Control embryos; (C,E) embryos injected with PP2A:B56
morpholino unilaterally. (F) Western blot showing injected ß-catenin was
less stable in the neural ectoderm of PP2A:B56
knockdown embryos. EFGP
was used as a control for both injection and loading.
