Improved PE-based Targeted Toxins: A Therapeutic with Increased Effectiveness

Targeted toxins (e.g., immunotoxins) are therapeutics that have at least two important components: (1) a toxin domain that is capable of killing cells and (2) a targeting domain that is capable of selectively localizing the toxic domain to only those cells which should be killed. By selecting a targeting domain that binds only to certain diseased cells (e.g., a cell which only expresses a cell surface receptor when in a diseased state), targeted toxins can kill the diseased cells while allowing healthy, essential cells to survive.

Novel Regulatory B cells for Treatment of Cancer and Autoimmune Disease

The manner by which cancers evade the immune response is not well-understood. What is known is that the manner is an active process that regulates immune responses employing at least two types of suppressive cells, myeloid-derived suppressive cells and regulatory T cells (Tregs), a key subset of CD4+ T cells that controls peripheral tolerance to self- and allo-antigens. Tregs are considered to play a key role in the escape of cancer cells from anti-tumor effector T cells.

3D Image Rendering Software for Biological Tissues

Available for commercial development is software that provides automatic visualization of features inside biological image volumes in 3D. The software provides a simple and interactive visualization for the exploration of biological datasets through dataset-specific transfer functions and direct volume rendering. The method employs a K-Means++ clustering algorithm to classify a two-dimensional histogram created from the input volume. The classification process utilizes spatial and data properties from the volume.

Gene Signature for Predicting Solid Tumors Patient Prognosis

HCC is the most frequent malignant tumor in the liver and the third leading cause of cancer death worldwide.  A progressive sequence of somatic mutations and epigenetic changes of oncogenes or tumor suppressor genes are believed to cause tumor development. However, high genomic instability in tumors causes the accumulation of genomic aberrations that do not contribute to tumor progression. Therefore, it is important to distinguish between ''driver'' mutations that are functionally important and ''passenger'' mutations that do not provide a selective advantage to the tumor cells.

Assays for Measuring and Quantifying DNA Damage

Exposure to ionizing radiation or agents that induce DNA double-stranded breaks (DSBs), which is one of the most damaging types of lesions in DNA, can result in damage to cells and/or tissues.  Thiscan lead to illness (i.e., Acute Radiation Syndrome, Cancer) or death.  Identifying the amount of exposure to a DNA DSB-causing agent can be useful in determining the need for further testing, avoidance or modification of certain medical procedures, and/or types of medical treatments.

Method for Targeted Therapeutic Delivery of Proteins into Cells

Current methods to deliver proteins into cells (e.g., using retrovirus, DNA transfection, protein transduction, microinjection, complexing the protein with lipids, etc.) have many shortcomings, such as lack of target specificity toxicity, or unwanted random integration into the host chromosome.  Protein transduction is an emerging technology for delivering proteins into cells by exploiting the ability of certain proteins to penetrate the cell membrane.  However, the majority of the proteins delivered by this means are usually trapped and subsequently degraded in the endosomes-lyso

High-throughput Assay to Identify New Cancer Drugs

 The National Cancer Institute seeks parties interested in collaborative research to evaluate or commercialize a diagnostic tool that can identify new drugs that increase chromosome instability.  Although chromosomal instability is generally thought of as a driver of tumor growth, a threshold level exists where CIN becomes a barrier to tumor growth and therefore can be exploited therapeutically.
