The National Cancer Institute (NCI) Division of Cancer Epidemiology and Genetics (DCEG) Immunoepidemiology Branch is seeking statements of capability or interest from parties interested in collaborative research to further co-develop a gene-based diagnostic for Hepatitis C virus (HepC, HCV).
Certain members of the cucurbitacin and Withanolide family have been identified that can sensitize some tumor cell lines to cell death (apoptosis) on subsequent exposure of the cells to pro-apoptotic receptor agonists (PARAS) of the TRAIL "death receptors". These PARAS include TRAIL itself, and agonist antibodies to two of its receptors death receptor-4 (DR4 or TRAIL-R1) and death receptor 5 (DR5, TRAIL-R2).
The only currently available treatment for Menkes disease, subcutaneous copper histidinate injections, is successful only in patients with ATP7A gene mutations that do not completely corrupt ATP7A copper transport function (estimated 20-25% of affected patients) and when started at a very early age (first month of life). The combination of viral gene therapy with copper injections provides working copies of the ATP7A copper transporter into the brain, together with a source of the substrate (copper) needed for proper brain growth and clinical neurodevelopment.
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.
Vascular Endothelial Growth Factor-A (VEGF-A) is an angiogenic agent that drives blood vessel formation in solid tumors and other diseases, such as macular degeneration and diabetic retinopathy. Several therapies that target the ability of VEGF to stimulate angiogenesis have been approved. These therapies regulate VEGF-A activity by binding VEGF-A, thereby blocking VEGF-A from binding to its receptor on target cells. This technology utilizes a different approach to regulating VEGF-A activity by providing a VEGF-A protein antagonist that is produced by engineering native VEGF-A protein.
RNA nanoparticles have the potential to serve as excellent drug or imaging delivery systems due to their designability and versatility. Furthermore, the RNA nanoparticles of the invention are also capable of self-assembly and potentially form nanotubes of various shapes which offer potentially broad uses in medical implants, gene therapy, nanocircuits, scaffolds and medical testing.
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.
RNA interference (RNAi) is a naturally occurring cellular post-transcriptional gene regulation process that utilizes small double-stranded RNAs to trigger and guide gene silencing. By introducing synthetic RNA duplexes called small-interfering RNAs (siRNAs), we can harness the RNAi machinery for therapeutic gene control and the treatment of various diseases.
Antibody drug conjugates (ADC) can demonstrate high efficacy as cancer therapeutics, however, much more can be done to improve their efficacy and safety profile. Site-specific antibody drug conjugation is a promising way to do this. Scientists at the NCI’s Laboratory of Experimental Immunology have identified a fully human monoclonal antibody, m860, that binds to cell surface-associated Her2 with affinity comparable to that of Trastuzumab (Herceptin) but to a different epitope.
Adoptive immunotherapy is a promising new approach to cancer treatment that engineers an individual''s innate and adaptive immune system to fight against specific diseases, including cancer with fewer side-effects and more specific anti-tumor activity in individual patients. T cell receptors (TCRs) and Chimeric Antigen Receptors (CARs) are proteins that recognize antigens in the context of infected or transformed cells and activate T cells to mediate an immune response to destroy abnormal cells.
