We assessed feeding-related developmental anomalies in the LgDel mouse model of Chromosome 22q11 Deletion Syndrome (22q11DS), a common developmental disorder that frequently includes perinatal dysphagia - debilitating feeding, swallowing and nutrition difficulties from birth onward - within its phenotypic spectrum. LgDel pups gain significantly less weight during the first postnatal weeks, and have several signs of respiratory infections due to food aspiration. Most 22q11 genes are expressed in anlagen of craniofacial and brainstem regions critical for feeding and swallowing, and diminished expression in LgDel embryos apparently compromises development of these regions. Palate and jaw anomalies indicate divergent oro-facial morphogenesis. Altered …
Conserved Structural Domains In Foxd4l1, A Neural Forkhead Box Transcription Factor, Are Required To Repress Or Activate Target Genes, Steven L. Klein, Karen M. Neilson, John Orban, Sergey Yaklichkin, Jennifer Hoffbauer, Kathy Mood, Ira O. Daar, Sally Ann Moody

FoxD4L1 is a forkhead transcription factor that expands the neural ectoderm by down-regulating genes that promote the onset of neural differentiation and up-regulating genes that maintain proliferative neural precursors in an immature state. We previously demonstrated that binding of Grg4 to an Eh-1 motif enhances the ability of FoxD4L1 to down-regulate target neural genes but does not account for all of its repressive activity. Herein we analyzed the protein sequence for additional interaction motifs and secondary structure. Eight conserved motifs were identified in the C-terminal region of fish and frog proteins. Extending the analysis to mammals identified a high scoring …
