SUPPLEMENTARY INFORMATION: The
technology relates to the treatment of
asthma and pulmonary fibrosis. When
airway inflammation occurs (e.g., during
an asthmatic attack or a response to an
allergen), the number of cells that
produce the receptor for IL–13 increases
in the lungs. When IL–13 interacts with
the receptor, an inflammatory response
is induced; when this occurs in the
lungs, it leads to the symptom of
constricted breathing. Blocking the
interaction between IL–13 and its
receptors on the cells has been shown
to reduce the inflammatory response.
A chimeric molecule was developed
that comprised both an IL–13 domain
(capable of interacting with its cognate
receptor) and a toxin domain. This
molecule has the capacity to interact
with and kill IL–13 receptor expressing
cells. The invention relates to a method
of treating asthma or pulmonary fibrosis
by administering a chimeric molecule
comprising a toxin linked to an IL–13
targeting moiety (e.g., IL13–PE38). By
administering the toxin in this form,
cells involved in airway inflammation
can be selectively targeted and killed,
thereby alleviating the symptom of
constricted breathing.
The prospective exclusive license will
be royalty bearing and will comply with
the terms and conditions of 35 U.S.C.
209 and 37 CFR part 404.7. The
prospective exclusive license may be
granted unless within sixty (60) days
from the date of this published notice,

This invention describes methods for
diagnosis and therapy of cancer and
other pathologies associated with
oxidative stress by administering a
nitroxyl contrast agent and employing
magnetic resonance imaging (MRI).
Tumor tissues exhibit viable but
hypoxic regions that allow them to
reduce nitroxide compounds more
efficiently than normal tissue. The
paramagnetic relaxivity of nitroxide
compounds makes it possible to use
standard MRI scanners to determine the
redox status of tissue in vivo. By
determining the redox status of a tumor
it is possible to not only diagnose a
tumor due to its enhanced reduction of
intracellular nitroxide contrast agent,
but also to determine appropriate
radiation treatment fields spatially to
deliver therapeutic doses of radiation,
and to determine appropriate timing
sequences after the administration of a
nitroxide contrast agent such that the
maximum difference between normal
and tumor tissue with respect to the
radioprotective form of the nitroxide is
present in the normal tissue, thereby
limiting collateral damage to the normal
tissue.
In addition to licensing, the
technology is available for further
development through collaborative
research opportunities with the
inventors.
Susceptibility-Matched Multiwell Plates
for High-Throughput Screening by
Magnetic Resonance Imaging and
Spectroscopy
Kenneth W. Fishbein (NIA).
U.S. Provisional Application No. 60/
725,299 filed October 12, 2005 (HHS
Reference No. E–243–2005/0-US–01).
Licensing Contact: Chekesha Clingman;
301/435–5018;
clingmac@mail.nih.gov.
This invention describes the
development of a multi-well assay plate
for high-throughput screening by
magnetic resonance imaging (MRI) and
nuclear magnetic resonance (NMR)
spectroscopy. Multi-well plates are used
in a wide variety of high-throughput
measurements in clinical chemistry and
immunology, as well as in drug
discovery and other research
applications. Magnetic resonance
imaging (MRI) of multi-well plates offers
the possibility of performing new kinds
of high-throughput assays, including the
detection of magnetic nanoparticles
attached to or within cells. Moreover,
MRI-guided localized nuclear magnetic
resonance (NMR) spectroscopy could be
used to perform detailed chemical
analysis of complex mixtures of
metabolites not possible by any other
common analytical technique. Best of

all, conventional MRI techniques exist
which would permit all samples in one
or more multi-well plate(s) to be
analyzed simultaneously.
Unfortunately, conventional multi-well
plates typically give poor performance
for MRI-based assays since they provide
inadequate matching of magnetic
susceptibility between the plate, the
sample and their surroundings. This
results in distortion of the magnetic
field within the scanner and thus
reduces the sensitivity for detecting
magnetic particles and the resolution of
NMR spectra. This invention relates to
a new multi-well plate design
incorporating one-piece polyetherimide
plastic construction for improved
magnetic susceptibility matching for
aqueous samples. This design can easily
be extended to non-aqueous samples by
the selection of an appropriate,
commercially-available plastic resin or
resin blend. Further enhancement in
susceptibility matching can be
accomplished by combining the new
plate design with plugs for each well
constructed from the same plastic as the
plate. These plugs would allow the
entire thickness of each sample to be
scanned in chemical analyses,
improving signal-to-noise ratio and
sensitivity. These plugs can be
integrated into a single ‘‘cap mat’’ so
that the entire assembly can be filled
and manipulated by standard robotic
laboratory equipment already in wide
use in the pharmaceutical industry.
Alternatively, spherical wells, accessed
by narrow fill holes, may be molded
into a solid plate, eliminating the need
for individual plugs to seal each well.
The new multi-well plate/plug design
reduces magnetic field distortions and
should dramatically improve spectral
resolution and sensitivity for NMR and
MRI-based high-throughput screening.
In addition to licensing, the
technology is available for further
development through collaborative
research opportunities with the
inventors.

ionization-tandem mass spectrometry
method for measuring the absolute
quantities of fifteen endogenous
estrogens and their metabolites in
human urine. The method is sensitive,
specific, accurate, and precise. It
requires a single hydrolysis/extraction/
derivatization step and only 0.5 mL of
urine, yet is capable of simultaneously
quantifying estrone, its 2- and 4methoxy derivatives, and its 2-, 4-, and
16a-hydroxy derivatives; estradiol, its 2and 4-methoxy derivatives, and its 2and 16a-hydroxy derivatives; 2hydroxyestrone-3-methyl ether; 16epiestriol; 17-epiestriol; and 16ketoestradiol in premenopausal and
postmenopausal women as well as men.
Standard curves are linear over a 103fold concentration range with the
relative standard error of the estimate
for the linear regression line ranging
from 1.2 to 7.3%, respectively. The
lower limit of quantitation for each
estrogen is 0.02 ng per 0.5-mL urine
sample (only 2 pg placed on column).
The percent recovery of a known added
amount of estrogen metabolite ranges
from 96 to 107%. The overall precision,
including the hydrolysis, extraction,
and derivatization steps, is 1–5%
relative standard deviation for samples
prepared concurrently and 1–12%
relative standard deviation for samples
prepared in separate batches.

Translation initiation factor eIF5A is
a highly conserved eukaryotic protein.
One of its lysine residues is
enzymatically modified, using
spermidine, to form an unusual amino
acid, hypusine, a posttranslational
modification unique to eIF–5A. This
eukaryotic initiation factor (eIF5A) and
its hypusine modification are essential
for mammalian cell proliferation.
Inventors at the National Institutes of
Health have recently cloned and
characterized the enzyme
deoxyhypusine hydroxylase (DOHH)
that catalyzes the final step in the
modification of eIF5A. The inventors
have characterized and cloned both the
yeast and human recombinant versions
of this enzyme.
Studies have shown that metal
chelating compounds like deferiprone
and ciclopirox olamine that inhibit
DOHH activity in cells also inhibit HIV–
1 replication in cell culture. These
findings suggest potential utility of
DOHH as a novel target for anti-cancer
and anti-retroviral therapy. These
advances could also conceivably lead to
the development of small molecule
inhibitors that bind to specific sites in
the enzyme.
In addition to licensing, the
technology is available for further
development through collaborative
research opportunities with the
inventors.

Ribonucleotide reductase is the ratelimiting enzyme of de novo DNA
synthesis. The enzyme is composed of
two homodimer subunits, hRRM1 and
hRRM2. Hydroxyurea, a ribonucleotide
reductase inhibitor, is commonly used
in conjunction with radiotherapy but it
its efficacy as shown in many
chemoradiation trials is limited.
Triapine (2-carboxyaldehyde pyridine
thiosemicarbazone), a novel
ribonucleotide reductase inhibitor,
exhibits sensitivity to the subunit
hRRM2 and inhibits ribonucleotide
reductase more effectively when
compared to hydroxyurea, thus
imparting a radiosensitizing effect.
This present invention provides
methods of preventing DNA synthesis
and DNA repair after exposing cells to
ionizing radiation. The present
invention further provides methods of
treating cancer and other tumors by
coadministration of a radiosensitizing
amount of Triapine and ionizing
radiation.

The FUS1 gene residing in the 3p21.3
chromosome region may function as a
tumor suppressor gene. Results show
that FUS1 null mutants show consistent
changes in NK cells and secreted
antibodies, suggesting that FUS1 plays
an important role in the development
and activation of the mammalian
immune system. The invention relates
to methods, systems and transgenic
animals useful for screening, diagnosing
and treating FUS1 related disorders.
Interestingly, targeted disruption of
FUS1 gene in mice resulted in a viable
and fertile phenotype.
Possible uses of this invention
include using the FUS1 protein to
modulate and boost the immune system
in diseases like cancer and AIDS. Also,
the cDNA and the corresponding
protein are small and the applications
could include gene therapy with

It requires a single hydrolysis/extraction/derivatization step and only
0.5 mL of urine, yet is capable of simultaneously quantifying estrone,
its 2- and 4-methoxy derivatives, and its 2-, 4-, and 16[alpha]-hydroxy
derivatives; estradiol, its 2- and 4-methoxy derivatives, and its 2-
and 16[alpha]-hydroxy derivatives; 2-hydroxyestrone-3-methyl ether; 16-
epiestriol; 17-epiestriol; and 16-ketoestradiol in premenopausal and
postmenopausal women as well as men. Standard curves are linear over a
103-fold concentration range with the relative standard
error of the estimate for the linear regression line ranging from 1.2
to 7.3%, respectively. The lower limit of quantitation for each
estrogen is 0.02 ng per 0.5-mL urine sample (only 2 pg placed on
column). The percent recovery of a known added amount of estrogen
metabolite ranges from 96 to 107%. The overall precision, including the
hydrolysis, extraction, and derivatization steps, is 1-5% relative
standard deviation for samples prepared concurrently and 1-12% relative
standard deviation for samples prepared in separate batches.
Immunogenic T Cell Targets in Autoimmune Hepatitis and Methods of Use
Barbara Rehermann (NIDDK) et al.
U.S. Provisional Application No. 60/659,513 filed March 7, 2005 (HHS
Reference No. E-263-2003/0-US-01)
Licensing Contact: Cristina Thalhammer-Reyero; 301/435-4507;
thalhamc@mail.nih.gov.
Available for licensing and commercial development are new methods
of diagnosing and monitoring the progression or response to therapy of
subjects with autoimmune hepatitis (AIH) by quantitating the frequency
and determining the function of autoantigen-specific CD4+ T cells in
the peripheral blood with HLA-DRB1*0301 tetramers that display the
autoepitopes. The invention identifies the immunogenic peptide regions
that are targets of the T-cell immune response in two types of
autoimmune hepatitis: (1) Anti-SLA (soluble liver antigen)-positive
autoimmune hepatitis type 3 and (2) anti-LKM (liver kidney microsomal
antigen)-positive autoimmune hepatitis type 2. Upon mapping the
immunogenic regions within SLA and P450 2D6 using short, overlapping
peptides, the inventors discovered at least four immunogenic peptides
within SLA and
[[Page 11215]]
at least one peptide within P450 2D6 that were recognized by HLA-
DRB*0301-restricted T cells. The technology is partially described in
Hepatology 2005; 42: 291A-292A.
In addition to licensing, the technology is available for further
development through collaborative research opportunities with the
inventors.

Available for licensing and commercial development are methods for
rapid and specific fluorescent staining of biological tissue samples
that substantially preserve biological molecules such as mRNA. Also
within the scope of the invention are methods for microdissecting
tissue to obtain pure populations of cells or tissue structures based
upon identifying and excising cells or tissue structures that are
labeled with fluorescent specific binding agents. A laser capture
microdissection (LCM) apparatus useful for identifying and isolating
cells and tissue structures following rapid immunofluorescent staining
is also disclosed. Other LCM devices are available for purchase from
Arcturus Engineering.
