The novel peptide HEADY specifies apical fate in a simple radially symmetric metazoan

Article Abstract:

The novel peptide HEADY of a simple, radially symmetric metazoan, Hydra, has been found to specify apical fate. HEADY is a short amidated peptide and the HEADY gene transcripts accumulate at the apical organizing center. If HEADY function is disrupted by dsRNA-mediated interference, severe head formation defects result. This study has given insight into how first asymmetry is specified in lower metazoans.

Dickkopf related genes are components of the positional value gradient in Hydra

Article Abstract:

The role of Dickkopf protein family related genes' expression in the regeneration and axis formation of hydra is analyzed. These genes, like Dickkopf, counteract Wnt signaling.
