Metastatic ovarian cancer mouse models and cell lines for preclinical studies

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.

Chimeric Antigen Receptors to CD276 for Treating Cancer

Chimeric antigen receptors (CARs) are hybrid proteins consisting of an antibody binding fragment fused to protein signaling domains that cause T-cells which express the CAR to become cytotoxic.  Once activated, these cytotoxic T-cells can selectively eliminate the cells which they recognize via the antibody binding fragment of the CAR.  By engineering a T-cell to express a CAR that is specific for a certain cell surface protein, it is possible to selectively target those cells for destruction.  This is a promising new therapeutic approach known as adoptive cell therapy.

Use of Cucurbitacins and Withanolides for the Treatment of Cancer

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). 

Hydrocarbon Stapled Peptides that Inhibit the Linear Ubiquitin Chain Assembly Complex (LUBAC) for the Therapy of the Activated B Cell-like (ABC) Subtype of Diffuse Large B Bell Lymphoma (A Type of Non-Hodgkin’s Lymphoma)

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin’s lymphoma and consists of three subtypes: activated B-cell (ABC), germinal center B-cell (GBC), and primary mediastinal B-cell (PMB). Despite advances in the front-line therapy for DLBCL, approximately one-third of patients will relapse. Substantially worse outcomes have been reported for patients diagnosed with ABC DLBCL and treated with standard chemoimmunotherapy, suggesting the need for novel strategies that improve treatment outcomes.

Mouse Xenograft Model for Mesothelioma

The National Cancer Institute is seeking parties interested in collaborative research to co-develop, evaluate, or commercialize a new mouse model for monoclonal antibodies and immunoconjugates that target malignant mesotheliomas.  Applications of the technology include models for screening compounds as potential therapeutics for mesothelioma and for studying the pathology of mesothelioma.
