Little is known about how the generation of specific neuronal types at stereotypic positions within the hindbrain is linked to Hox gene-mediated patterning. Here, we show that during neurogenesis, Hox paralog group 2 genes control both anteroposterior (A-P) and dorsoventral (D-V) patterning. Hoxa2 and Hoxb2 differentially regulate, in a rhombomere-specific(More)
Little is known about the genetic pathways involved in the early steps of inner ear morphogenesis. Hoxa1 is transiently expressed in the developing hindbrain; its targeted inactivation in mice results in severe abnormalities of the otic capsule and membranous labyrinth. Here we show that a single maternal administration of a low dose of the vitamin A(More)
Early organization of the vertebrate brainstem is characterized by cellular segmentation into compartments, the rhombomeres, which follow a metameric pattern of neuronal development. Expression of the homeobox genes of the Hox family precedes rhombomere formation, and analysis of mouse Hox mutations revealed that they play an important role in the(More)
Guanylate-binding proteins (GBPs) were originally described as proteins that are strongly induced by interferons and are capable of binding to agarose-immobilized guanine nucleotides. hGBP1, the first of two members of this protein family in humans, was recently shown to represent a novel type of GTPase that hydrolyzes GTP predominantly to GMP. We now(More)
