Cell culture investigations using spheroids and organoid models have had a major impact on biomedical advancement as alternative sources for costly, in vivo animal testing.  However, these 3-D cell constructs are limited in that they do not integrate extracellular components within the structure important for more reliable and accurate biological responses.  Extracellular matrix (ECM) from decellularized tissues provide a physical scaffolding and offers crucial biochemical and biomechanical cues for cellular constituents.

Diverse human cancers like colorectal, pancreatic, ovarian, melanoma, and pre-cancers express NADPH oxidases (NOX) at high levels. Reactive oxygen species (ROS) produced from metabolic reactions catalyzed by NOX in tumors are essential to the tumor’s growth. Though drugs that inhibit ROS production by NOX could be effective against a variety of human cancers, these types of drugs are not widely available.

Adoptive cell transfer (ACT) uses tumor infiltrating lymphocytes (TILs) that recognize antigens expressed by cancer cells (neoantigens). Neoantigen specific TIL administration in patients has resulted in long-term regression of certain metastatic cancers. However, current procedures for TIL therapy are highly invasive, labor-intensive, and time consuming. The success of these procedures is limited and differs between patients and histologies.

Adoptive cell therapy (ACT) using tumor-specific T cells can produce positive clinical responses in some cancer patients. Nevertheless, several obstacles to the successful use of ACT for the treatment of cancer and other conditions remain. For example, one or more of the in vivo persistence, survival, and antitumor activity of tumor-specific T cells can, in some cases, decrease following adoptive transfer. Accordingly, there is a need for methods of obtaining a robust population of tumor-specific T cells for ACT.

Lung metastases are a sign of widespread cancer with poor survival rate. Lung malignancies can originate from almost any cancer type spread via the blood stream. Most common lung metastases are from melanoma, breast cancer, bladder cancer, colon cancer, prostate cancer, neuroblastoma, and sarcoma. Living more than 5 years with lung metastases is uncommon, and surgical procedures are only effective with localized lung metastases. Lung metastasis are extremely frequent and resistant to regular treatment due to immunosuppressive regulatory sulfatide-reactive type II NKT cells.

Cytokines are a broad category of intercellular signaling proteins that are critical for intercellular communication in human health and disease. However, systematic profiling of cytokine signaling activities has remained challenging due to the short half-lives of cytokines, and the pleiotropic functions and redundancy of cytokine activities within specific cellular contexts.

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. 

Griffithsin is a potent anti-viral protein with activity against HIV, HCV, Sars, HSV 1 & 2 and other viruses.  It is active against HIV and HCV at picomolar concentrations.  Griffithsin is moving into clinical trials as an anti-HIV microbicide. Based on the structure of griffithsin and the necessities of pharmaceutical product development and regulatory approval, certain mutations in the sequence of griffithsin have been generated which could add to the stability and solubility of the protein.

Multiparametric MRI improves image detail and prostate cancer detection rates compared to standard MRI. Computer aided diagnostics (CAD) used in combination with multiparametric MRI images may further improve prostate cancer detection and visualization. The technology, developed by researchers at the National Institutes of Health Clinical Center (NIHCC), is an automated CAD system for use in processing and visualizing prostate lesions on multiparametric MRI images.

The AKT pathway plays a key role in the regulation of cellular survival, apoptosis, and protein translation and has been shown to have prognostic significance in a number of cancers.  Recently, the inventors have identified several functions of the AKT pathway in certain cancers, such as extrahepatic cholangiocarcinoma (EHCC).
