Abstract excerpt
Dlx transcription factors are implicated in patterning the mammalian jaw, based on their nested expression patterns in the first branchial arch (primordium for jaw) and mutant phenotypes; inactivation of Dlx1 and Dlx2 (Dlx1/2-/-) causes defects in the upper jaw, whereas Dlx5/6(-/-) results in homeotic transformation of the lower jaw into upper jaw. Therefore, the 'Dlx codes' appear to regionalize the jaw...
