Key pathways regulated by HoxA9,10,11/HoxD9,10,11 during limb development.

ABSTRACT:

Background

The 39 mammalian Hox genes show problematic patterns of functional overlap. In order to more fully define the developmental roles of Hox genes it is necessary to remove multiple combinations of paralogous and flanking genes. In addition, the downstream molecular pathways regulated by Hox genes during limb development remain incompletely delineated.

Results

In this report we examine limb development in mice with frameshift mutations in six Hox genes, Hoxa9,10,11 and Hoxd9,10,11. The mice were made with a novel recombineering method that allows the simultaneous targeting of frameshift mutations into multiple flanking genes. The Hoxa9,10,11 (-/-) /Hoxd9,10,11 (-/-) mutant mice show a reduced ulna and radius that is more severe than seen in Hoxa11 (-/-)/Hoxd11 (-/-) m
