Assessing candidate DLX‐regulated genes in the first pharyngeal arch of chick embryos
Abstract Background Insights into the development and evolution of asymmetrical jaws will require an understanding of the gene regulatory networks that underpin the differential morphogenesis of the maxillary and mandibular domains of the first pharyngeal arch in a variety of gnathostomes.

Targeted Disruption of Hotair Leads to Homeotic Transformation and Gene Derepression
Long noncoding RNAs (lncRNAs) are thought to be prevalent regulators of gene expression, but the consequences of lncRNA inactivation in vivo are mostly unknown. Here, we show that targeted deletion of mouse Hotair lncRNA leads to derepression of hundreds

Novel regulation of the homeotic gene Scr associated with a crustacean leg-to-maxilliped appendage transformation. [PDF]
Homeotic genes are known to be involved in patterning morphological structures along the antero-posterior axis of insects and vertebrates. Because of their important roles in development, changes in the function and expression patterns of homeotic genes ...

Control of Arabidopsis apical-basal embryo polarity by antagonistic transcription factors. [PDF]
Plants, similarly to animals, form polarized axes during embryogenesis on which cell differentiation and organ patterning programs are orchestrated. During Arabidopsis embryogenesis, establishment of the shoot and root stem cell populations occurs at ...

Homeobox genes in normal and abnormal vasculogenesis [PDF]
Homeobox containing genes are a family of transcription factors regulating normal development and controlling primary cellular processes (cell identity, cell division and differentiation) recently enriched by the discovery of their interaction with ...

_Limusaurus_ and bird digit identity [PDF]
_Limusaurus_ is a remarkable herbivorous ceratosaur unique among theropods in having digits II, III and IV, with only a small metacarpal vestige of digit I. This raises interesting questions regarding the controversial identity of avian wing digits.
