Craniofacial Defects

Tricho-rhino-phalangeal syndromes (TRPS) are caused by mutation or deletion of TRPS1, a gene encoding a GATA transcription factor. These disorders are characterized by abnormalities of the hair, face, and selected bones. Rare cases of individuals with TRPS displaying supernumerary teeth have been reported, but none of these has been examined molecularly. We used two different approaches to investigate a possible role of TRPS1 during tooth development. We looked at the expression of Tprs1 during mouse tooth development and analyzed the craniofacial defects of Trps1 mutant mice. In parallel, we investigated whether a 17-year-old Thai boy with clinical features of TRPS and 5 supernumerary teeth had mutation in TRPS1. We report here that Trps1 is expressed during mouse tooth development, and that an individual with TRPS with supernumerary teeth has the amino acid substitution A919V in the GATA zinc finger of TRPS1. These results suggest a role for TRPS1 in tooth morphogenesis.

ABSTRACT The Caenorhabditis elegans run gene encodes a Runt domain factor. Runx1, Runx2, and Runx3 are the three known mammalian homologs of run. Runx1, which plays an essential role in hematopoiesis, has been identified at the breakpoint of chromosome translocations that are responsible for human leukemia. Runx2 plays an essential role in osteogenesis, and inactivation of one allele of Runx2 is responsible for the human disease cleidocranial dysplasia. To understand the role of run in C. elegans, we used transgenic run::GFP reporter constructs and a double-stranded RNA-mediated interference method. The expression of run was detected as early as the bean stage exclusively in the nuclei of seam hypodermal cells and lasted until the L3 stage. At the larval stage, expression of run was additionally detected in intestinal cells. The regulatory elements responsible for the postembryonic hypodermal seam cells and intestinal cells were separately located within a 7.2-kb-long intron region. This is the first report demonstrating that an intron region is essential for stage-specific and cell type-specific expression of a C. elegans gene. RNA interference analysis targeting the run gene resulted in an early larva-lethal phenotype, with apparent malformation of the hypodermis and intestine. These results suggest that run is involved in the development of a functional hypodermis and gut in C. elegans. The highly conserved role of the Runt domain transcription factor in gut development during evolution from nematodes to mammals is discussed.

ABSTRACTPattern recognition receptors allow animals to sense microbe associated molecular patterns and mount effective immune responses. It is not clear howCaenorhabditis elegansrecognizes pathogenic microbes in absence of classical pattern recognition pathways. Here, we asked if sensory neurons ofC. elegansallow it to distinguish between pathogens. Exposure ofC. elegansto a Gram positive bacteriumEnterococcus faecalisor to a Gram negative bacteriumPseudomonas aeruginosashowed predominantly pathogen-specific signatures. Using nematodes defective in sensory perception, we show that neuronal sensing is essential to mount pathogen specific immune response. OSM-6 expressing, ciliated neurons exert non-cell autonomous control of immune effector production via an OSM-6-FSHR-1 GPCR axis as well as an OSM-6-HLH-30/TFEB transcription factor axis duringE. faecalisinfection. OSM-6-FSHR-1 axis also controls immune response toP. aeruginosa. In all, this study delineates essential role of sensory perception in the regulation of pathogen-specific immunity inC. elegans.
