Abstract:
A composition is disclosed which is capable of being used for detection, comprising an encapsulated noble metal nanocluster. Methods for preparing the encapsulated noble metal nanoclusters, and methods of using the encapsulated noble metal nanoclusters are also disclosed. In certain embodiments, the noble metal nanoclusters are encapsulated by a dendrimer, a peptide, a small organic or inorganic molecule, or an oligonucleotide. The encapsulated noble metal nanoclusters have a characteristic spectral emission, wherein said spectral emission is varied by controlling the nature of the encapsulating material, such as by controlling the size of the nanocluster, the generation of a dendrimer, the incorporation of a functional group, and wherein said emission is used to provide information about a biological state. The emission is selected from the group consisting of nanocluster fluorescence, multiphoton excited nanocluster fluorescence, Stokes or Anti-Stokes Raman emission from the encapsulating material, and second harmonic generation.

Abstract:
The Wnt signaling pathways are involved in embryo development as well as in M tumorigenesis. Dishevelled (DvI) tra®'duces Wnt signals from the receptor Frizzled (Fz) to downstream components in canonical and non-canonical Wnt signaling pathways, and the DvI , PDZ domain plays an essential role in both pathways, and the DvI PDZ .domain binds directly to Fz receptors. In the present invention using NMR-assisted virtual ligand screening, several compounds were identified and were found to bind to the DvI PDZ domain. Molecular dynamics simulation was used to analyze the binding between the PDZ domain and these compounds in detail. These compounds provide a basis for rational design of high-affinity inhibitors of the PDZ domain, which can block Wnt signaling by interrupting the Fz-DvI interaction.
