Gene Profiling Arrays

Ena Wang, Lance Miller, Francesco Marincola (NCI)

DHHS Reference No. E-086-00/0 filed 28 Mar 2000

Licensing Contact: Richard Rodriguez; 301/496-7056 ext. 287; e-mail: rr154z@nih.gov

The invention(s) embodied in this application, provides for ordered arrays of mixtures of nucleic acid molecules, which reflect the gene expression profile of one or more specimens, such as different cell types or tissues. In particular embodiments, complete mRNA mixtures (i.e. gene transcripts) or cDNA representatives from specimens are individually arrayed on a substrate. Such mixtures of nucleic acids can be derived from any specimen source, including animal, plant and/or microbial cells and can be assembled in any collection desired. The collections can, for instance, include nucleic acid mixtures from different cell types, different phenotypes, cells grown under different conditions, cells of different ages or developmental stages, and so forth. The nucleic acid arrays are provided in both macro- and micro-formats and are suitable for measuring the relative abundance of particular gene transcripts across a collection of complex nucleic acid mixtures.

Techniques are also disclosed for producing high-fidelity, amplified mixtures of nucleic acid molecules using a combination of RNA (sense or anti-sense) amplification and template-switching synthesis. Amplified mixtures produced using this method can, for instance, be applied to the disclosed arrays. The disclosed arrays allow high throughput analysis of differential gene expression in a specimen, such as a tumor, or a variety of specimens, such as a variety of tumors, and is suitable for automated preparation and analysis.

The Isolation of a New Gene, TRAG, Associated with TGF-Beta

Snorri S. Thorgeirsson, Sean R. Sanders (NCI)

DHHS Ref. No. E-047-00/0 filed 07 Mar 2000 and 60/187,848 filed 08 Mar 2000

Licensing Contact: Susan S. Rucker; 301/406-7056 ext. 245; e-mail: sr156v@nih.gov

A new gene has been isolated from a cell line resistant to a protein, TGF-beta, which can block the proliferation of cancer cells. This resistance endows the cell with cancer forming abilities. The protein encoded by the newly-discovered TRAG gene has been found at much higher levels in these cancer-forming cells than their non-cancerous ancestors. In addition, the TRAG protein is greatly elevated in many other rodent and human cancer cell lines and in primary mouse liver tumors, but not in surrounding non-tumorous tissue. This indicates a strong association between TRAG and cancer-forming potential. TRAG may be involved in the mechanism by which normal cells become cancerous. The TRAG gene could provide an excellent target for cancer or gene therapy. Abrogation of TRAG protein production using anti-sense oligonucleotides or antibodies could conceivably prevent, reduce, or destroy certain types of tumors.

Identification of a Novel Domain in the Tumor Necrosis Factor Receptor Ligand Family that Mediates Pre-Ligand Receptor Assembly and Function

MJ Lenardo, FK Chan, R Siegel (all of NIAID)

Serial No. 60/181,909 filed 11 Feb 2000

Licensing Contact: Susan S. Rucker; 301/496-7056 ext. 245; e-mail: sr156v@nih.gov

This application discloses the identification of a functional domain, which is essential for signaling involving receptors of the Tumor Necrosis Factor Superfamily (TFNR's) including TNFR-1 (p60), TNFR-2 (p80), Fas, TRAIL-R, LTβR, CD40, CD30, CD27, HVEM, OX40 and DR4. The functional domain, denoted the Pre-Ligand Assembly Domain (PLAD), can be isolated as functional polypeptides which can be useful in inhibiting the first step in TNFR mediated signaling, ligand-independent assembly of members of the TNFR Superfamily. The ability to inhibit TNFR signaling suggests that these PLAD polypeptides may be useful in developing new therapeutic molecules or as therapeutic molecules themselves for modulation of immune responses, apoptosis, and inflammation.

In addition to being available for license, the investigators who have developed this technology are also willing to consider entering into a CRADA relationship with companies interested in commercial development of this technology.

Transition Metal Complexes of N,N′,N″-trialkyl-cis,cis-1,3,5-triaminocyclohexane and Related Compositions and Methods

Martin W Brechbiel, Roy P. Planalp, Kim A. Deal (NCI)

DHHS Reference No. E-072-99/0 filed 10 Aug 1999

Licensing Specialist: Girish C. Barua; 301/496-7735 ext. 263; gb18t@nih.gov

The invention is directed to copper complexes of N,N′,N″-trimethyl-cis,cis-1,3,5-triaminocyclohexane and N,N′,N″-triethyl-cis,cis-1,3,5-triaminocyclohexane as well as methods of producing and using said complexes. These complexes are capable of cleaving DNA and RNA in vitro and could be used for the treatment of cancer or other disease states that are characterized by abnormal cellular proliferation. The complexes could also be used as delivery agents or as imaging-tracers. These complexes offer advantages over previously described cleaving methodologies, e.g., oxidative or transesterification protocols. The disclosed copper-complexes act via hydrolytic reactions. These advantages could offer significant benefits over related therapeutic approaches to the aforementioned abnormal conditions.
