Sequences Encoding Two Novel Human Polyomaviruses

    Description of Invention: Researchers at the National Cancer 
Institute, NIH, have discovered two species of a previously unknown 
polyomavirus genus.
    Polyomaviruses are a diverse group of DNA-based viruses that infect 
humans and various animals. At least one human polyomavirus, the Merkel 
cell polyomavirus (MCV), plays a causal role in the development of an 
unusual form of skin cancer called Merkel cell carcinoma. The coat 
proteins of polyomaviruses can spontaneously assemble into virus-like 
particles (VLPs) similar to those that have been used in the recent 
vaccines against human papillomaviruses (HPVs).
    Applications:
    <bullet> Development of clinical diagnostic assays to detect 
linkages between the new polyomaviruses and human cancers.
    <bullet> Development of a VLP-based prophylactic vaccine similar to 
the HPV vaccine.
    Advantages: DNA sequences have broad applications in the studies of 
polyomavirus infection mechanisms and carcinogenesis. Notably, they 
are:
    <bullet> Identification and purification of the normal and mutated 
polyomaviral proteins.
    <bullet> Studies of antisense oligonucleotides in polyomavirus 
biology.
    <bullet> Development of polyclonal and monoclonal antibodies 
against polyomaviruses.
    Development Status: Pre-clinical.

Fenoterol and Fenoterol Analogues for Treatment of Glioma, 
Glioblastoma, and Astrocytoma

    Description of Invention: To date there is no effective treatment 
for the brain tumors or brain cancers indentified as gliomas, 
glioblastomas, or astrocytomas.
    This technology relates to the discovery that fenoterol and related 
analogues block astrocytoma and glioblastoma cell division at low 
doses. In a xenograft model utilizing the 1321N1 astrocytoma tumor 
implanted in the flank of SKID mice, the (R,R)-4-methoxyfenoterol 
analogue significantly decreased tumor growth relative to a control 
group receiving vehicle and studies utilizing [\3\H]-(R,R)-4-
methoxyfenoterol have shown that the compound readily passes the blood-
brain barrier. The anti-tumor effect is associated with the ability of 
fenoterol and related analogues to induce production of cyclic 
adenosine monophosphate (cAMP), which is normally decreased in 
glioblastomas and astrocytomas. Induced cAMP production inhibits brain 
tumor growth in vivo. Fenoterol and related analogues are beta-2 
adrenergic receptor ([beta]2 AR) agonists and the anti-tumor effect is 
associated with the expression of this receptor. Since there is a 
heterogeneous expression of [beta]2 AR in human brain tumors, patients 
who will respond to fenoterol therapy can be predetermined leading to 
individualized treatment. In addition to use in the initial treatment 
of brain tumors, the systemic and CNS bioavailability of the drug after 
oral

[[Page 55800]]

administration and the minimal systemic toxicity suggest that fenoterol 
and it analogs can be used in the adjuvant treatment of patients with 
[beta]2 AR-positive gliomas, glioblastomas or astrocytomas. Studies 
with a number of fenoterol analogs and CNS-implanted tumors are in 
progress.
    The fenoterol analogues discussed in this technology are subject to 
HHS Ref. No. E-205-2006/3 (U.S. Patent Application No. 12/376,945 and 
PCT Publication No. WO/2008/022038).
    Applications: Therapeutic in the front line and adjuvant treatment 
of glioma, glioblastoma and astrocytoma.
    Advantages: Potential first-in-class therapeutic for multiple types 
of brain tumors.
    Development Status: In vivo: tumor models in SKID mice. In vitro: 
cell-based assays using human glioblastoma and astrocytoma cell lines. 
Further in vivo studies in animal models are underway.
    Market: Approximately 17,000 Americans are diagnosed with gliomas 
annually (http://www.mayoclinic.org/glioma/).

Chemical Attraction: Cell Lines Expressing the CXCR1 or CXCR2 Chemokine 
Receptors

    Description of Invention: Chemoattractant receptors have been 
identified as important factors in regulating many innate and adaptive 
immune responses. Modulation of these receptors have implications for 
shifting immune responses to create either a dampening effect in 
fighting inflammatory diseases, such as autoimmune diseases or 
cardiovascular diseases, or a boosting effect to generate more 
effective responses to infectious agents, tumors, and promote wound 
healing. Chemokine receptors are expressed on a variety of tumor cells 
and play a role in helping cancer cells sense new microenvironments for 
metastatic growth.
    Scientists at the National Institutes of Health (NIH) have 
developed human embryonic kidney (HEK) 293 cell lines that express the 
CXCR1 chemokine receptor or the CXCR2 chemokine receptor. These two 
receptors are also known as the IL-8 receptor-alpha and IL-8 receptor-
beta, respectively. They both effectively bind IL-8, a potent 
neutrophil chemoattractant, as well as other chemokines with varying 
affinities. The collection of cell lines produced by these scientists 
includes HEK 293 cells that express the wild-type CXCR1, wild-type 
CXCR2, or mutant variants of each receptor. The cell lines were created 
by stably transfecting vectors containing the cDNA for each receptor 
into HEK 293 cells. HEK 293 cells transfected with the wild-type CXCR1 
or CXCR2 display strong chemoattractant properties when placed in the 
presence of their corresponding CXC family chemokines, such as IL-8.
    Application:
    <bullet> Research tools for testing the activity of potential drugs 
and chemokine analogs in their ability to block cellular responses 
triggered by CXC chemokines, such as inflammatory responses induced by 
IL-8
    <bullet> Cell lines expressing the wild-type CXCR1 or CXCR2 can 
serve as positive controls in chemokine receptor studies designed to 
identify novel chemoattractants or agents that inhibit chemokinetic 
functions.
    <bullet> Research tool for screening compounds that block these 
receptors as a possible anti-cancer agent to inhibit angiogenesis and 
metastasis
    Advantages:
    <bullet> Both wild-type and mutant cell lines available: Wild-type 
CXCR1/CXCR2 receptors or mutant receptors with point and deletion 
mutations have been cloned into HEK 293 cells. These cell lines will 
have varying degrees of potency for their chemoattractant responses to 
provide a range of functional comparisons in chemokine studies.
    <bullet> Experimental verification of response to CXC family 
chemokines: The scientists have compiled years of data over various 
publications indicating that these receptors respond appropriately to a 
profile of chemokines.

DLC-1 Gene Deleted in Cancers

    Description of Invention: Chromosomal regions that are frequently 
deleted in cancer cells are thought to be the loci of tumor suppressor 
genes, which restrict cell proliferation. Recurrent deletions on the 
short arm of human chromosome 8 in liver, breast, lung and prostate 
cancers have raised the possibility of the presence of tumor suppressor 
genes in this location.
    The inventors have discovered the deletion of human DLC-1 gene in 
hepatocellular cancer (HCC) cells. They have performed in vitro 
experiments demonstrating the deletion in over 40% of human primary HCC 
and in 90% of HCC cell lines. The DLC-1 gene is located on human 
chromosome 8p21.3-22, a region frequently deleted in many types of 
human cancer. DLC-1 mRNA is

[[Page 55801]]

expressed in all normal tissues tested, but it has either no or low 
expression in a high percentage of several types of human cancer, such 
as liver, breast, lung, and prostate cancers. Through in vitro and in 
vivo tumor suppression experiments, the inventors further demonstrated 
that DLC-1 acts as a new tumor suppressor gene for different types of 
human cancer.
    Applications:
    <bullet> Method to diagnose HCC.
    <bullet> Method to treat HCC patients with DLC-1 compositions.
    <bullet> Transgenic model to study HCC and other types of human 
cancer.
    <bullet> DLC-1 compositions.
    Market:
    <bullet> Primary liver cancer accounts for about 2% of cancers in 
the U.S., but up to half of all cancers in some undeveloped countries.
    <bullet> 251,000 new cases are reported annually.
    <bullet> Post-operative five year survival rate of HCC patients is 
30-40%.
    Development Status: The technology is currently in the pre-clinical 
stage of development.
