The invention listed below is owned by an agency of the U.S. Government and is available for licensing and/or co-development in the U.S. in accordance with 35 U.S.C. 209 and 37 CFR part 404 to achieve expeditious commercialization of results of federally-funded research and development.
Scientists at the National Cancer Institute developed a cell line designated A549 that was derived from explanted cultures of human lung cancer tissue. The A549 cell line has been tested under the guidance of the United States Food and Drug Administration (FDA) so, under current Good Manufacturing Practices (GMP), these cells may be suitable for use in manufacturing constructs for use in clinical trials.
The high mortality rate from ovarian cancers can be attributed to late-stage diagnosis and lack of effective treatment. Despite enormous effort to develop better targeted therapies, platinum-based chemotherapy still remains the standard of care for ovarian cancer patients, and resistance occurs at a high rate. One of the rate limiting factors for translation of new drug discoveries into clinical treatments has been the lack of suitable preclinical cancer models with high predictive value.
The National Cancer Institute seeks interested parties to co-develop transgenic mice having immunocompetent rat growth hormone-firefly Luciferase-enhanced green fluorescent protein.
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.
The retinal pigment epithelial cells (RPE) make up a polarized monolayer in the vertebrate eye that separates the neural retina from the choroid, and performs a crucial role in retinal physiology by forming a blood-retinal barrier and closely interacting with photoreceptors to maintain visual function. Many ophthalmic diseases, such as age-related macular degeneration, are associated with a degeneration or deterioration of the RPE.
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
