Neurogenesis requires factors that regulate the decision of dividing progenitors to leave the cell cycle and activate the neuronal differentiation program. It is shown here that the murine runt-related gene Runx1 is expressed in proliferating cells on the basal side of the olfactory epithelium. These include both Mash1+ olfactory receptor neuron (ORN)(More)
The cystic fibrosis transmembrane conductance regulator (CFTR) gene exhibits a tightly regulated pattern of expression in human epithelial cells. The mechanism of this regulation is complex and is likely to involve a number of genetic elements that effect temporal and spatial expression. To date none of the elements that have been identified in the CFTR(More)
The cystic fibrosis transmembrane conductance regulator gene (CFTR) exhibits a complex pattern of expression that shows temporal and spatial regulation, although the control mechanisms are not fully known. We have mapped DNase-I-hypersensitive sites (DHSs) flanking the CFTR gene with the aim of identifying potential regulatory elements. We previously(More)
The cystic fibrosis transmembrane conductance regulator gene (CFTR) shows a tightly regulated pattern of expression with spatial and temporal control. The regulatory elements achieving this appear to lie outside the basal promoter of the gene. We previously identified DNase I hypersensitive sites (DHSs) at -79.5 kb and -20.5 kb with respect to the CFTR(More)
Transcriptional corepressors of the Groucho (Gro)/TLE family play important roles during a variety of developmental pathways, including neuronal differentiation. In particular, they act as negative regulators of neurogenesis, together with Hairy/Enhancer of split (Hes) DNA-binding proteins. The interaction with Hes1 leads to Gro/TLE hyperphosphorylation and(More)
Transcriptional corepressors of the Groucho/transducin-like Enhancer of split (Gro/TLE) family regulate a number of developmental pathways in both invertebrates and vertebrates. They form transcription repression complexes with members of several DNA-binding protein families and participate in the regulation of the expression of numerous genes. Despite(More)
BACKGROUND The cystic fibrosis transmembrane conductance regulator gene (CFTR) shows a complex pattern of expression. The regulatory elements conferring tissue-specific and temporal regulation are thought to lie mainly outside the promoter region. Previously, we identified DNase I hypersensitive sites (DHS) that may contain regulatory elements associated(More)
The CFTR gene exhibits a complex pattern of expression that shows temporal and spatial regulation though the control mechanisms have not been fully elucidated. We have mapped DNase I hypersensitive sites (DHS) flanking the CFTR gene to identify potential regulatory elements. We previously characterized DHS at -79.5 and -20.9 kb with respect to the CFTR(More)
Transcriptional corepressors of the Groucho/transducin-like Enhancer of split (Gro/TLE) family are involved in a variety of cell differentiation mechanisms in both invertebrates and vertebrates. They become recruited to specific promoter regions by forming complexes with a number of different DNA-binding proteins thereby contributing to the regulation of(More)
The cystic fibrosis transmembrane conductance regulator (CFTR) gene shows a complex pattern of expression, with temporal and spatial regulation that is not accounted for by elements in the promoter. One approach to identifying the regulatory elements for CFTR is the mapping of DNase I hypersensitive sites (DHS) within the locus. We previously identified at(More)
