The NCI Laboratory of Cancer Biology and Genetics seeks parties interested in collaborative research to further develop this mouse model of triple-negative breast cancer (TNBC) to study cancer biology and for preclinical testing. As a Research Tool, patent protection is not being pursued for this technology; more information to access this strain can be found here: https://www.jax.org/strain/030386.
Cancer stem cells are a minority population of cells in tumors that initiate and sustain the cancer and which are resistant to therapy; they may cause tumors to recur after curative treatment. Current therapies generally do not target cancer stem cells.
Researchers at the NCI Radiation Oncology Branch and NIH CIT Center for Molecular Modeling developed a tetrahydroxamate chelation technology that provides a more-stable Zr-89 complex as an immuno-PET cancer imaging agent. In either the linear or the macrocyclic form, the tetrahydroxamate complexes exhibit greater stability as chelating agents compared to Zr-89 complexed to the siderophore desferrioxamine B (DFB), a trihydroxamate, which represent
Aberrant function of the WNT-b-catenin pathway is a common underlying cause of tumorigenesis. Despite the attractiveness of the WNT-b-catenin pathway as a therapeutic target, WNT dependent cell signaling is also crucial for normal tissue development, and is ubiquitous in all organs. As a result, WNT-b-catenin pathway inhibitors cause many side effects and fail to meet FDA safety standards. A more targeted approach is needed to develop safe and effective WNT signaling inhibitors.
KRAS and other Ras-family enzymes are an important component of over 30% of human cancers, however, no effective therapeutics targeting Ras or Ras-driven cancers are currently available. The production of Ras proteins in vitro is required for the identification and characterization of Ras targeting drugs. An important step in producing the Ras protein involves prenylation of the C-terminus of the protein via farnesyltransferase, a modification that does not occur in prokaryotic organisms. Previous attempts to generate properly processed Ras in eukaryotic cells has
The Surgery Branch of the National Cancer Institute is seeking statements of capability or interest from parties interested in collaborative research to carry out genotypic as well as phenotypic analysis of the 888 mel cell line in order to better understand the nature of tumor cells that respond to therapy. In addition, this cell line can be used as a target of humoral or cell mediated immune responses as a part of studies characterizing the nature of immune responses directed against tumor cells.
The successful development of new cancer therapeutics requires reliable preclinical data that are obtained from mouse models for cancer. Human tumor xenografts, which require transplantation of human tumor cells into an immune compromised mouse, represent the current standard mouse model for cancer. Since the immune system plays an important role in tumor growth, progression and metastasis, the current standard mouse model is not ideal for accurate prediction of therapeutic effectiveness in patients.
The National Institute on Drug Abuse's Medications Discovery Research Branch is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize 4-phenylpiperazine derivatives as dopamine D3 selective ligands.
Research and clinical applications of induced pluripotent stem (iPS) cells are currently limited by reprogramming methods that may modify the host genome, and therefore be potentially unsafe and problematic for use in basic research, cell-based therapies, and drug-discovery applications.
