... pharyngeal endoderm, in the ascidian Ciona intestinalis . We found that knockout of Hox1 causes posterior-to-anterior transformation of the endostyle identity, and that Hox1 represses Otx expression and anterior identity, and vice versa. Furthermore, alteration of the regional identity of the endostyle...
