Abstract:
The present invention provides a nucleic acid comprising a) a nucleotide sequence encoding one or more pro-apoptotic proteins, and b) a nucleotide sequence encoding one or more tumor-specific and/or tissue-specific promoters. Also provided is a method of treating cancer, comprising administering the compositions of this invention to a subject.
Abstract:
The present invention provides a composition comprising a chimeric polypeptide comprising a recall antigen that reactivates memory T cells in a subject and a new antigen that activates naïve B cells in a subject and a composition comprising a nucleic acid encoding a chimeric polypeptide comprising a recall antigen that reactivates memory T cells in a subject and a new antigen that activates naïve B cells in a subject. Further provided are methods of eliciting an immune response, as well as treating and/or preventing disease in subjects in whom the ability to mount an immune response to a new antigen is impaired, by administering the compositions of this invention.
Abstract:
The present invention provides cells comprising an isolated nucleic acid encoding a novel lactate dehydrogenase (LDH) and/or the encoded LDH polypeptide. The invention further provides cells comprising an isolated nucleic acid encoding LDH, wherein the cell is capable of producing and secreting insulin. Also provided are methods of providing fuel-stimulated (e.g., glucose-stimulated) insulin secreting capability to a mammalian subject by implanting cells of the invention (e.g., in a semi-permeable membrane and/or an implantable device) into the subject. Further provided are devices comprising the cells of the invention. In particular embodiments, the device is an implantable device.
Abstract:
The present invention includes methods for producing nanocrystals of semiconductor material that have specific crystallographic features such as phase and alignment by using a self-assembling biological molecule that has been modified to possess an amino acid oligomer that is capable of specific binding to semi-conductor material. One form of the present invention is a method to construct ordered nanoparticles within the liquid crystal of the self-assembling biological molecule.
Abstract:
This application describes intracellular, cytoplasmic molecules that are translocated to the surface of a microorganism and participate in binding the microorganism to the surface of a host cell. Examples of such translocated molecules include glycerahdehyde 3-phosphate dehydrogenase, pyruvate dehydrogenase, and elongation factor-Tu. Regions oftranslocated molecules important for binding, as well as molecules which disrupt binding, are described. Antibodies directed to translocated molecules are also described.
Abstract:
A method for the production of a robust, chemically stable, crystalline, passivated nanoparticle and composition containing the same, that emit light with high efficiencies and size-tunable and excitation energy tunable color. The methods include the thermal degradation of a precursor molecule in the presence of a capping agent at high temperature and elevated pressure. A particular composition prepared by the methods is a passivated silicon nanoparticle composition displaying discrete optical transitions.
Abstract:
The process of detecting RNA molecules in situ using the 3SR amplification process, for example where the molecules are translocation-junction-spanning molecules in cells that have undergone chromosomal translocation. Also process modifications that enhance its effectiveness.
Abstract:
Described herein are portable apparatuses and methods of creating fibers, such as microfibers and nanofibers. The methods discussed herein employ centrifugal forces to transform material into fibers. Portable apparatuses that may be used to create fibers are described.
Abstract:
Disclosed herein are compounds and compositions having the structure of Formula I, which are useful in the treatment of diseases, such as cancer, where inhibition of MTHl is expected to confer an advantage to a patient. Methods of inhibition of MTHl activity in a human or animal subject are also provided.
Abstract:
Methods for detecting and treating prostate cancers are provided. In some aspects, methods for detecting a prostate cancer comprise measuring a level of PRUNE2 expression and/or PCA3 expression in a sample from a subject. In further aspects, a method for treating prostate cancer is provided comprising administering a PRUNE2 tumor suppressor polypeptide or a nucleic acid molecule that inhibits expression of PC A3 RNA.
