The hedgehog signalling pathway is a conserved mechanism which acts in inductive processes in both vertebrate and invertebrate development to direct growth and patterning. In Drosophila, the secreted Hedgehog protein acts as a signal to induce non-autonomous activation in adjacent cells of either the decapentaplegic or wingless genes (both of which encode growth factor-like molecules), via inac...
The extraordinary electronic and mechanical properties of graphene have stimulated intense research on developing simple methods for the large-scale synthesis of graphene. High-quality large-area graphene films prepared by the chemical vapor deposition of various carbon-containing molecules on arbitrary substrates could meet the requirements of large-area electronic applications. For the indust...
Developmental pathways are networks of genes that act coordinately to establish the body plan. Disruptions of genes in one pathway can have effects in related pathways and may result in serious dysmorphogenesis or cancer. Environmental exposures can be associated with poor pregnancy outcomes, including dysmorphic offspring or children with a variety of diseases. An important goal of environment...
This work presents a novel three-dimensional (3-D) scattering model to predict the path loss of a microcellular radio channel in an urban environment. The analytical scattering model combined with a patched-wall model predicts the median path loss more accurately than the conventional analytical ray-tracing model in the cases studied. Comparing the path loss with the measured one at 1.8 GHz dem...
Patched 1 (Ptch1) has epithelial, stromal and systemic roles in murine mammary gland organogenesis, yet specific functions remain undefined. Cre-recombinase-mediated Ptch1 ablation in mammary epithelium increased proliferation and branching, but did not phenocopy transgenic expression of activated smoothened (SmoM2). The epithelium showed no evidence of canonical hedgehog signaling, and hyperpr...
Patched-1 (Ptch1) has epithelial, stromal, and systemic roles in murine mammary gland organogenesis, yet specific functions remain undefined. Cre-recombinase-mediated Ptch1 ablation in mammary epithelium increased proliferation and branching, but did not phenocopy transgenic expression of activated Smoothened (SmoM2). Epithelium showed no evidence of canonical hedgehog signaling, and hyperproli...
Recent evidence suggests that Ca(2+)-permeable AMPA receptors display rapid, short-lasting current facilitation. In this study, we investigated the properties of AMPA receptor-mediated synaptic currents in medial septal neurons of the rat in an in vitro slice preparation. Immunocytochemistry with a selective antibody to the GluR2 subunit revealed that both choline acetyltransferase-containing a...
Mutations in PATCHED (PTC), the human homolog of the Drosophila patched gene, have been identified in most exons of the gene in patients with the basal cell nevus syndrome and in sporadic basal cell carcinomas. We have screened the 23 PTC exons for mutations using single strand conformation polymorphism analysis of DNA from 86 basal cell nevus syndrome probands, 26 sporadic basal cell carcinoma...
