Mouse Macula Densa Cell Line

Description of Invention: This technology provides a clonally derived macula densa cell line (MMDD1 cells) that closely mimics the known molecular expression pattern of native macula densa (MD) cells. MMDD1 cells are developed from SV-40 transgenic mice using fluorescence-activated cell sorting of renal tubular cells labeled with segment-specific fluorescent lectins. The MMDD1 cells of this technology express COX-2, bNOS, NKCC2, and ROMK, but not Tamm-Horsfall protein, and show rapid 86Rb+ uptake that is inhibited by a reduction in NaCl concentration and by bumetanide or furosemide. These MMDD1 cells provide a useful in vitro model for the study of Macula Densa function.

Novel Analogues of the Natural Product Schweinfurthin With Specificity for Tumors and Other Disease Manifestations Associated With Neurofibromatosis Type 1

Description of Invention: The global anti-cancer market is forecast to reach $40 billion by 2012. There remains a significant unmet need for therapies to treat neurofibromatosis type 1 (“NF1”), a common genetic disease that afflicts 1 in 3500 people, and malignant tumors carrying NF1 mutations, including tumors of the central and peripheral nervous systems.

Researchers at the National Cancer Institute (“NCI”)-Frederick investigating genetic influences on cancer susceptibility of the nervous system have synthesized novel analogues of Schweinfurthin, a natural compound first isolated from the tropical African plant Macaranga schweinfurthii, to which glioma and leukemia cell lines show significant sensitivity. The Schweinfurthin analogues also have inhibitory activity against mouse and human NF1 cancer cell lines. The analogues have a novel mode of action that appears to involve regulation of cytoskeletal reorganization.

These inhibitors are likely to be accepted in the marketplace because their potent, selective activity and unique specificity in mode of action gives them a distinct advantage over the mechanisms of other existing therapies.

Applications:

  • Therapies for tumors associated with NF1 (including brain and peripheral nervous system tumors).
  • Therapies for leukemia.
  • Therapies for NF1 and associated conditions.

Advantages:

  • Utilizes proven small-molecule technology.
  • Specificity of mode of action may reduce potential side-effects.
  • Novel mode of action may limit market competition.

Development Status: Pre-clinical.

Detection of Autoantibodies for the Diagnosis of Sjogren's Syndrome

Description of Invention: This invention provides a method for diagnosing Sjogren's syndrome in a subject. In tests utilizing blood from human volunteers, this method demonstrated dramatically higher accuracy (76%) in positively diagnosing Sjogren's syndrome than a standard, currently available immunoassay (46%).

Briefly, this invention employs a panel of mammalian-derived proteins and protein fragments that are often antigentic in individuals with Sjogren's syndrome in concert with a luciferase immunoprecipitation system. In contrast, most currently available immunoassays for diagnosis of rheumatological diseases include either antigens from recombinant bacterial expression systems or single antigens from bovine sources. These immunoassays are likely to fail to present the sufficient variety of specific human epitopes that are necessary for high accuracy diagnoses of Sjogren's syndrome.

Applications:

  • Diagnosis of Sjogren's syndrome.
  • A component of a panel of diagnostic tests for patients with autoimmune disease symptoms.

Advantages: Higher accuracy than currently available diagnostics of Sjogren's syndrome.

Development Status: Early stage. Initial clinical screens have been completed.

Market: According to the Sjogren's Syndrome Foundation, Inc., it takes on average seven years for a positive Sjogren's syndrome diagnosis as symptoms of this syndrome mimic other conditions and diseases. Up to four million individuals in the United States have Sjogren's syndrome, and half of currently diagnosed cases occur in concert with other autoimmune disease (http://www.sjogrens.org/​home/​about-sjogrens-syndrome).Start Printed Page 4573
