  • Publication number: 20140336202
    Abstract: Methods of treating subjects with cancer and screening for MDM2 inhibitors that may be effective cancer therapeutics are provided herein. The cancers that may be treated using MDM2 inhibitors using the methods described herein include those that are or may become resistant to treatment with tyrosine kinase inhibitors. Methods of treating subjects with cancers that have, or develop in response to treatment with tyrosine kinase inhibitors, elevated levels of MDM2, Mcl-1 or PP5 or decreased levels of Huwe1 or CAS using MDM2 inhibitors are provided herein. The MDM2 inhibitors may be effective at treating these cancers alone or in combination with a tyrosine kinase inhibitor regardless of p53 status (mutant or wild-type) of the cancer.

  • Publication number: 20120089180
    Abstract: A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

  • Publication number: 20070297984
    Abstract: The presently disclosed subject matter generally relates to methods and compositions for inhibiting the expression and/or activation of hypoxia-inducible factor 1 (HIF-1) genes in a hypoxic cell. More particularly, the methods disclosed herein relate to inhibition of HIF-1 activation in a cell, increasing sensitivity of a tumor cell to radiation and/or chemotherapy, delaying tumor growth, inhibiting tumor blood vessel growth, inhibiting inflammatory responses in a cell through the use of compositions that prevent the nitrosylation of HIF-1, and methods for screening for new inhibitors of HIF-1 activiation. Additionally, the compositions disclosed herein relate to compositions that can be employed in, and are identified by, the disclosed methods.

  • Publication number: 20070135373
    Abstract: A method for controlling in vivo heat-inducible gene expression for provision of therapeutic polypeptide. The method includes the steps of: (a) providing a construct comprising a polynucleotide encoding a therapeutic polypeptide, wherein the polynucleotide is operatively linked to a heat-inducible promoter; (b) administering the construct to a warm-blooded vertebrate at a site at or near the tumor; and (c) applying heat to the site at or near the tumor to express the therapeutic polypeptide, whereby anti-tumor activity is observed.
