Abstract: A method for isolating candidate peptides for the treatment of a disease or disorder with a causative agent with SOD activity, the method comprising the steps of: (i) contacting a plurality of candidate peptides with a first agent with SOD activity and being causative of the disease or disorder and isolating the bound peptides; and (ii) contacting the peptides isolated form step (i) with a second agent structurally related to the first agent but without SOD activity and isolating the unbound peptides; wherein the peptides isolated from step (ii) are candidate peptides for treatment of the disease. Peptides identified using the screening method may be used to treat AD, type II diabetes, Scrapie and Transmissible Spongiform Encephalopathies such as Creutzfeldt Jacob disease (CJD), variant CJD, Gerstmann Strausler Schinkler syndrome and Bovine Spongiform Encephalopathy (BSE).
Abstract: Zinc finger proteins of the Cys2His2 type represent a class of malleable DNA binding proteins which may be selected to bind diverse sequences. Typically, zinc finger proteins containing three zinc finger domains, like the murine transcription factor Zif268 and the human transcription factor Sp1, bind nine contiguous base pairs (bp). To create a class of proteins which would be generally applicable to target unique sites within complex genomes, the present invention provides a polypeptide linker that fuses two three-finger proteins. Two six-fingered proteins were created and demonstrated to bind 18 contiguous bp of DNA in a sequence specific fashion. Expression of these proteins as fusions to activation or repression domains allows transcription to be specifically up or down modulated within cells. Polydactyl zinc finger proteins are broadly applicable as genome-specific transcriptional switches in gene therapy strategies and the development of novel transgenic plants and animals.

Abstract: Linear extended polymeric paramagnetic chelates for use as MRI contrast agents are synthesized by conjugating DTPA chelator moieties to higher than 90% of the monomer residues of the polyamino acid backbone chain. The resulting polymer can be labeled with Gd, since each chelator moiety holds a Gd ion, and the resulting conformation is of an unfolded, extended linear type, capable of entering small pores and moving around obstacles in the extracellular space of tissues. The efficient production of these extended polymers is critical for the application of such contrast agents to medical imaging. One such agent is a reptating polymer containing technetium-99.

Abstract: This invention characterizes the specific peptide fragment derived from specially prepared zinc charged fetuin and a method of preparation thereof, wherein the fragment was found to contain an apoptosis-inducing activity. Specifically, the amino acid sequence of this peptide is H-T-F-S-G-V-A-S-V-E and correlates to amino acid no. 300-309 of fetuin, referred to herein as Fetuin Peptide Fragment (FPF 300-09). FPF 300-09 strongly induced apoptosis in LNCaP (prostate cancer) and HT-29 (colon cancer) cells without affecting CCD 18 Co (normal colon) cells. The in vitro tissue culture study demonstrated that the FPF 300-09 is more potent than the parent molecule (full-length zinc charged fetuin) in inducing apoptosis. FPF 300-09 has a LD50 of 0.3-0.4 &mgr;M, while the LD50 for zinc-charged fetuin is 3-10 &mgr;M.

Abstract: Protein polymers coated with a metal are provided. New methods are described for the preparation of tubulin-based microtubules such that they may be coated, by an electroless plating method, with gold particles of <20 nm in diameter without prior reaction with noble metal catalysts. The gold particle deposition can occur in suspension or on microtubules lying on a surface. Gold enhancement of the gold-particle coating and annealing results in ohmic conductance that is within a factor of ten of the resistivity of bulk gold. These methods are likely to be applicable to other protein polymers.

Abstract: A novel encoding system, compositions for use therein and methods for determining the source, location and/or identity of a particular item or component of interest is provided. In particular, the present invention utilizes a collection of one or more sizes of populations of semiconductor nanocrystals having characteristic spectral emissions, to “track” the source or location of an item of interest or to identify a particular item of interest. The semiconductor nanocrystals used in the inventive compositions can be selected to emit a desired wavelength to produce a characteristic spectral emission in narrow spectral widths, and with a symmetric, nearly Gaussian line shape, by changing the composition and size of the semiconductor nanocrystal. Additionally, the intensity of the emission at a particular characteristic wavelength can also be varied, thus enabling the use of binary or higher order encoding schemes.
Abstract: This invention provides therapeutic and diagnostic agent delivery vehicles, including viral vectors, that are complexed to a targeting moiety by coordinate covalent linkages mediated by a transition metal ion. The complex is typically formed with a transition metal ion that is in a kinetically labile oxidation state; after the complex is formed, the oxidation state of the transition metal ion is changed to one that renders the complex kinetically stable. The use of a coordinate covalent linkage to attach the targeting moiety to the delivery vehicle provides advantages such as the ability to readily attach a different targeting moiety to a delivery vehicle without modifying the delivery vehicle itself. This flexibility is achieved without sacrificing stability of the complex.
