Translational Genomics Center
The
completion of the Human Genome Project will transform medical research
and disease therapy. However, important steps will need to occur
before we can realize true breakthroughs in disease prevention,
diagnosis, and treatment. The Human Genome Project provides us with
sequence information only. By analogy, we now have the "table
of contents" of the genetic encyclopedia (= the human genome),
the exact "volume" (= chromosome), the precise location
of each "chapter" (=gene), and the accurate "wording"
(=sequence) of human DNA. We must still however add several additional
layers of information to each gene sequence. Lung investigators
must understand what genes are expressed in pulmonary conditions,
what is the function of that gene expression, and how does it contribute
to human disease.
Functional
genomics laboratories use post-genomic technologies to speed up
data acquisition related to gene expression patterns and the function
of thousand of genes. Their goal is to provide functional and applicable
information in a high throughput mode. One example of such a tool
is the use of microarrays, that allow investigators to simultaneously
profile the behavior of complete genomes.
The PACCM division has established the Functional
Genomics Resource Center adjacent to the Dorothy
P. & Richard P. Simmons Center for Interstitial Lung Disease.
The Center is under the leadership of Dr.
Naftali Kaminski. The mission of this Center is to facilitate
the implementation of post-genomic methods for analysis in pulmonary
research. This unique center aims to take advantage of the combination
of clinical and scientific excellence of the PACCM Division. A well
established UPMC Tissue Bank provides a wealth of clinical samples
to make a significant contribution in the application of genomics
methods to pulmonary disease management and diagnosis.
The
FGRC has put a special focus on making microarray research feasible
for researchers at the division. Tissue or cells are obtained by
clinicians or researchers with appropriate IRB or IACAC approval.
The center is responsible for archiving the tissue, extracting the
RNA, and preparing probe RNA. A complete system for hybridization
and scanning of microarrays including a Genepix microarray 4000B
scanner, an incubator shaker and the complete equipment necessary
to prepare samples for Codelink, Agilent, Affymetrix or any other
microarray platform are available to researchers. Scanning of Affymetrix
arrays is performed by the Genomics
and Proteinomics core facility at the University of Pittsburgh.
A Dell workstation is available to the scientists. Software for
word processing, spreadsheets, statistics, graphics, and database
are installed as well as Matlab and Statistica software packages.

The
academic software packages for gene expression analysis installed
include: Tools for normalization and statistical reading of microarray
results including D-chip, A variety of clustering and visualization
tools including: Cluster, Treeview, Expander, GeneCluster II and
BRB array-tools. Statistical analysis and classification packages
including: Scoregene, PAM and SAM. The unique probabilistic relational
modeling viewer GeneExpress, GenMapp Pathway analysis software.
Additionally installed are Codelinktm System software, Imagene 5
and Affymetrix Microarray Analysis suite 5. Instruction and supervision
are provided by Lara Chensny and by Dr Naftali Kaminski.
The science of proteomics allows the more "downstream"
monitoring of the behavior of thousands of proteins resulting from
gene expression.. The proteomics setup includes 2D separation equipment,
a Typhoon DIGE 9400 workstation, a Decider 2D gel Analysis software,
and a Z4000 image analysis system.
The Center's main projects include the classification, prognosis
prediction, and identification of new molecular targets for therapeutic
intervention in pulmonary fibrosis, emphysema, acute lung injury,
early detection of lung cancer, and basic metabolic mechanisms of
sleep apnea. The next phase of the center will include the application
of more sophisticated methods for looking at the role of specific
cell types in diseases process (laser capture microdissection systems)
and automating the proteomics effort.
Currently the Center is staffed by members of Dr Kaminski's team,
as well as Dr. Prabir Ray, Dr.
Augustine Choi, Dr. Yingze Zhang,
and Dr. Kevin Gibson.
