An Improved Chromosomal Comparative Genomic Hybridization (CGH) Microarray for the Detection of Cancer Associated Genome Amplification and Deletion Events

Description of Technology: The progression and therapeutic response of cancer is closely associated with chromosomal instability (i.e. genomic amplifications and deletions). The most widely used technique to detect these small changes in the genome is CGH. CGH utilizes nucleic acid hybridization to oligonucleotide features corresponding to specific, predetermined regions of the genome to detect DNA copy number changes. Due to the size of the human genome, it is necessary to have high-density features to detect small amplification and deletion events within the genome.

The current invention is based on a CGH microarray with oligonucleotide features that provides a high-density coverage. More specifically, the inventors have used 60-mer oligonucleotide features within a previously shown set of 36 tumor associated genes/genomic regions and have successfully detected small changes in DNA copy number with high density coverage (1 feature per 400bp). Furthermore, the inventors have used a fade-out design for coverage of the flanking regions and cover the remainder of the genome at an average density of 1 feature per 100kb.

Applications:

1. CGH microarray can be used to detect small regions of genomic instability within cancer associated genes, while larger events can also be detected with similar efficacy.

2. Gene amplification and deletion profiles of patient samples can be used in diagnosis and therapeutic decision making.

Advantages:

1. Easy to use, CGH microarray technique, based on current technology.

2. Technology detects small changes in tumor associated genomic instability Start Printed Page 45253more efficiently than current available technologies.

3. The average coverage of Agilent oligoarray is 1 per 35kb of human genome, while the average coverage of the currently described technology is 1 per 400bp.

Developmental Status: The technology is ready for use.

Benefits: More than 600,000 cancer deaths are estimated to occur in 2007. Efficient diagnosis and informed decision making will aid in improved clinical management of cancer. This technology can rapidly diagnose cancer and thus help in proper clinical management leading to improved overall survival and quality of life of patients suffering from cancer. The current in-vitro diagnostics market is valued at $30 billion dollars and expected to grow.

Methods and Compositions for Treating Diseases and Disorders Associated with Natural Killer T-Cells

Description of Technology: The invention relates to the discovery that C12 beta-D-galactosyl ceramide may be used to deplete or inactivate NKT cell populations. These findings suggest methods for using C12 beta-D-galactosyl ceramide to treat conditions that would benefit from depletion of NKT cells, such as certain autoimmune diseases (e.g. lupus, MS) and AIDS.

The presence of NKT cells can be associated with either beneficial effects or pathology. Deficiencies in NKT cells are associated with at least some types of autoimmune disease, including type 1 diabetes and autoimmune gastritis in mice. In contrast, NKT cells augment autoantibody secretion and lupus development in lupus-prone mouse models and therefore lupus patients may benefit from the depletion of NKT cells. The remission state of multiple sclerosis (MS) is also associated with decreased levels of NKT cells, suggesting NKT cell depletion as a method of treatment for MS.

P53 and VGEF Regulate Tumor Growth of NO2 Expressing Cancer Cells

Description of Technology: The increased expression of nitric oxide synthase 2 (NOS2), an inducible enzyme that produces nitric oxide (NO), has been found in a variety of human cancers. It also has been shown that NOS2-specific inhibitors can reduce the growth of experimental tumors in mice. These findings suggest a pathophysiological role for NO in the development and progression of cancer. However, the function of NO and NOS2 in carcinogenesis is uncertain. NO had been found to either inhibit or stimulate tumor growth, and high concentrations of NO also are known to induce cell death in many cell types including tumor cells. On the other hand, the lower concentrations of NO that are found in human tissue can have an opposite effect and protect against programmed cell death, or apoptosis, from various stimuli. The role of NO and NOS2 in tumor progression, particularly with respect to p53, therefore need to be further defined.

This invention comprises methods of screening for modulators of NOS2 expression in p53 mutant cells, both in vivo and in vitro, as well as methods for predicting the chemotherapeutic benefit of administering NOS2-inhibitors to cancer patients. It has been demonstrated that NOS2-expressing cancer cells with wild-type p53 have reduced tumor growth in athymic nude mice whereas NOS2-expressing cancer cells with mutated p53 have accelerated tumor growth. Therefore, this invention has potential application for a number of cancers that overexpress NOS2 and have a high frequency of p53 mutations, including breast, brain, head, neck, lung and colon cancers.

Applications:

1. Method to treat cancer with NOS2 inhibitors.

2. Method to screen for NOS2 modulators.

3. Method to predict therapeutic benefits of NOS2 inhibitors in patients.

Market:

1. An estimated 1,444,920 new cancer diagnoses in the U.S. in 2007.

2. 600,000 deaths caused by cancer in the U.S. in 2006.

3. Cancer is the second leading cause of death in United States.

4. It is estimated that market for cancer drugs would double to $50 billion a year in 2010 from $25 billion in 2006.

Development Status: The technology is currently in the pre-clinical stage of development.
