Abstract excerpt
Vertebrate Hox genes are required for the proper organization of structures along the rostrocaudal axis. Hoxd-11 is expressed in the posterior part of the embryo, up to the level of prevertebra 27, and its expression boundary is reproduced by a Hoxd-11/lacZ transgene. Expression of this transgene anterior to prevertebra 27 is prevented by the silencing activity of a cis-acting element, region IX. Using transgenic...
