... focussed on the tritocerebrum shows that inactivation of vnd results in regionalized axonal patterning defects, which are comparable with the brain phenotype caused by mutation of the Hox gene labial ( lab ). However, in contrast to lab activity in specifying tritocerebral neuronal identity ,vnd...

... by differential Hox gene action, based on differential spatiotemporal expression patterns, protein sequence differences, interactions with co-factors and regulation of specific downstream genes. During embryonic development of the Drosophila brain, the Hox gene labial is required for the regionalized...

... that bind heterodimers of Labial -type Hox and PBC proteins. Normally, multimerized Labial-PBC binding sites are sufficient to trigger a Labial-specific activation response in either Drosophila or mouse embryos. Here we find that the 21 bp sequence element plays an important role in Deformed specificity...

... of Drosophila and mammals. We then carry out a genetic analysis of the labial gene in embryonic brain development. Our analysis shows that loss-of-function mutation and ubiquitous overexpression of labial results in ectopic expression of neighboring regulatory genes. Furthermore, this analysis demonstrates...

...Jens Riese; Gabi Tremml; Mariann Bienz ABSTRACT The Drosophila endoderm is patterned by the signals Decapentaplegic and Wingless secreted from the visceral mesoderm. This induction culminates in a precise pattern of spatially restricted expression of labial , a selector gene with a role in cell...

The extracellular dpp protein migrates from the visceral mesoderm across the apposing endodermal cell layer in a region of the endoderm that expresses the homeotic gene labial (lab) . Mesodermal expression of dpp is required...
