Researchers at the National Cancer Institute (NCI) have developed orthotopic allograft models for pancreatic cancer that utilize low passage primary pancreatic adenocarcinoma cells or tumor fragments implanted into the cancer-free pancreata of recipient syngeneic immunocompetent mice. Tumor development in these models is more synchronized, latency is substantially shortened, and tumors develop only in one location, as pre-determined by the choice of a site for cells/tumor fragment implantation.

Prostate cancer is the most prevalent form of cancer among all men in the United States (US). It is also the second leading cause of cancer-related deaths in the US among men, largely due to the progressively treatment resistant nature of the disease. Treatment options for early stage prostate cancer include watchful waiting, radical prostatectomy, radiation therapy, and importantly androgen-deprivation therapy (ADT). Prostate cancer is dependent on androgen hormones, such as testosterone, for sustaining and promoting growth.

The discovery and selection of suitable compounds for the treatment and prevention of autoimmune, inflammatory, and pain disorders is a significant challenge. Researchers at National Institute of Aging (NIA) mitigated this issue. They discovered and synthesized numerous novel fatty acid derivatives (novel small molecules) that may ameliorate these conditions and provide treatment options for these disorders. In a relevant rat model, the fatty acid derivatives developed by NIA demonstrated:

The National Cancer Institute's Urologic Oncology Branch is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize the use of Tempol to target HIF-2a in cancer.

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 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.

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.

Dopamine is a major neurotransmitter in the central nervous system and among other functions is directly related to the rewarding effects of drugs of abuse.  Dopamine signaling is mediated by D1, D2, D3, D4 and D5 receptors.  The dopamine D3 receptor is a known target to treat a variety of neuropsychiatric disorders, including substance use disorders (e.g. cocaine and opioid), schizophrenia and depression.
