Cooperative regulation of p53 by modulation of ternary complex formation with CBP/p300 and HDM2.

abstract：:Canonical Wnt signaling has been implicated in an AP axis polarizing mechanism in most animals, despite limited evidence from arthropods. In the long-germ insect, Drosophila, Wnt signaling is not required for global AP patterning, but in short-germ insects including Tribolium castaneum, loss of Wnt signaling affects d...
