  • Patent number: 10539565
    Abstract: Provided herein are methods for determining the risk that a subject diagnosed with colorectal cancer will develop a recurrence of colorectal cancer and methods of predicting clinical outcome for a subject diagnosed with colorectal cancer by a) determining the level of expression for each marker of a panel of markers in a panel of tumor compartments in a tumor tissue sample from the subject, wherein the panel of markers comprises at least two of TEM1, HIF2?, CAIX, PDGFR?, fibronectin, collagen I, collagen IV, and CD31 and wherein the panel of tumor compartments comprises at least three tumor compartments of pure stroma, tumor, stromal vessel, and tumor vessel; b) determining the TAPPS score for said subject; and c) comparing the TAPPS score of the subject to the TAPPS score of a population of subjects diagnosed with colorectal cancer. Also provided are related computer-implemented methods and systems, kits, and tumor microarrays.

  • Patent number: 10509037
    Abstract: This invention relates to novel monoclonal antibodies that specifically bind to the alpha-folate receptor. In some embodiments, the antibodies inhibit a biological activity of folate receptor-? (FR-?). The antibodies are useful in the treatment of certain cancers, particularly cancers that have increased cell surface expression of the alpha-folate receptor (“FR-?”), such as ovarian, breast, renal, colorectal, lung, endometrial, or brain cancer. The invention also relates to cells expressing the monoclonal antibodies, antibody derivatives, such as chimeric and humanized monoclonal antibodies, antibody fragments, and methods of detecting and treating cancer using the antibodies, derivatives, and fragments.

  • Patent number: 10253106
    Abstract: This invention relates to the use of monoclonal and polyclonal antibodies that specifically bind to and have the ability in the alternative to become internalized by cells expressing folate receptor alpha (FRA) and to induce an immune effector activity such as antibody-dependent cellular cytotoxicity. The antibodies are useful in specific delivery of pharmacologic agents to FRA-expressing cells as well as in eliciting an immune-effector activity particularly on tumor cells and precursors. The invention is also related to nucleotides encoding the antibodies of the invention, cells expressing the antibodies; methods of detecting cancer cells; and methods of treating cancer using the antibodies.

  • Patent number: 10053509
    Abstract: The invention provides methods for inhibiting the interaction of endosialin with endosialin ligands. The inhibition is effectuated on the genetic level, by inhibiting endosialin gene expression, and on the protein level, by blocking the interaction of cell-surface expressed endosialin with ligands such as fibronectin and collagen. The invention provides methods for identifying inhibitors of the interaction of endosialin with endosialin ligands. Also provided are methods for inhibiting angiogenesis and neovascularization in vivo and in vitro.

  • Publication number: 20120201843
    Abstract: The present invention provides nucleic acids containing transcriptional units that encode CYP1B1 polypeptides or portions thereof, wherein the transcriptional units lack sequences found in the untranslated region (UTR) of naturally occurring forms of the CYP1B1 transcript. The nucleic acids of the invention lack translational repressor elements and thus provide for a system of enhanced translation of the CYP1B1 polypeptide or portions thereof. Also disclosed are methods of administering nucleic acids to a mammal and use in the treatment of proliferative disorders or cancer.

  • Publication number: 20080081830
    Abstract: The invention is directed to the use of a pharmaceutical composition comprising an effective amount of zonisamide or a pharmaceutically acceptable salt thereof to treat tremors, such as rest tremors or action tremors. Tremors may include kinetic tremor, essential tremor, severe essential tremor, postural tremor, drug-induced tremor, toxic tremor, primary orthostatic tremor, dystonic tremor, neuropathic tremor, and cerebellar tremor. The use of zonisamide in the methods of the invention reduce adverse side effects of other drugs that are used to treat tremors. Zonisamide or a pharmaceutically acceptable salt thereof can also be used in conjunction with other therapeutic agents commonly used to treat tremors, thus enhancing the therapeutic effect of treating tremors.
