Why Mice?
• Mice get many of the same genetic disease as humans• Mammalian physiology is highly conserved• >95% of human genes have an ortholog in mouse• Conservation of gene content and organization• Experimentally tractable• Small, “easy” to breed• Short generation time
“The mouse is thebiomedical research platform for the
21st Century.”- Harold Varmus, Director, National
Cancer Institute

development and disease
• is there a gene expression signature that is common to lung development and lung cancer?
• are developmental gene expression signatures tissue specific?
Rudolf Virchow, 1859
old question; new approaches
genomes
genomics
informatics
• Embryonic (E9 – E12)– Primitive lung buds emerge from
ventral gut epithelium• Pseudoglandular (E12-E15)
– Stereo-specific branching of the lung bronchi. Differentiation of epithelial cells to form prealveolate saccules
• Canalicular (E15-E17)– Formation of terminal sacs and
vasculature • Saccular (Terminal Sac) (E17 – P0)
– Expansion in the numbers of terminal sacs and capillaries. Differentiation of Type I and II alveolar cells
• Alveolar (P1-P30)– terminal sacs develop into mature
alveolar ducts and alveoli

E = embryonicP = postnatal
Extract total mRNA from the target cell/tissue- presence of mRNA means a gene is “active”
Modify the mRNA with a tag
Hybridize modified mRNAs to the probes on the gene chip- successful hybridization generates a fluorescent signal
Scan for fluorescence
Quantitate expression
1. Bright spots indicates positive hybridization events (i.e. active genes)
2. The analysis software “knows” the address of every gene and generates a report of gene activity (expression)
time course analysis
Which genes have sustained transcriptional activity changes over time?
Expectations:• genes/pathways for cell division/cell cycle
should go down over time
• genes/pathways for differentiation and lung specific pathways go up over time

Divide up the developmental timeline into segments, bin the ~5,000 or so genes that have expression levels related to development.
Determine the frequency of genes in each bin where the human ortholog is overexpressed in tumors.
Determine the frequency of genes in each bin where the human ortholog is underexpressed in tumors.

quantifying developmental gene expression signatures
development and disease
• is there a gene expression signature that is common to lung development and lung cancer?
• are developmental gene expression signatures tissue specific?
developmental gene expression signatures for cancer are not tissue specific
not all cancers exhibit an early developmental gene expression signature
10 developmental time series32 disease data sets (mostly cancer)
Naxerova et al. 2008. Genome Biology. 9:R108
novel classification of tumors?
• group 1 – early development gene signatures– 46% of data sets tested fall into this group– lung cancer, Wilm’s tumor
• group 2 – ambiguous developmental signature– early developmental signature plus other
transcriptional programs– observed in CNS tumors, breast cancer
• group 3 – no early development signature– genes cluster on the late end of the DT– ovarian cancer, prostate cancer
• group 1 and 2 tumors (early developmental signatures)– cell cycle, RNA splicing, DNA repair– cellular location largely in nucleus
• group 3 tumors (late development signatures)– immune response, cell adhesion, – cellular location largely in extracellular matrix and cell
membrane
functional differences in expression-based classifications
summary• genomics of normal lung development is a
useful framework for identifying genes and networks that are dysregulated in lung cancer
• developmental gene signatures do not appear to be tissue specific
• not all cancers exhibit the same developmental gene signature
• the laboratory mouse allow us to investigate early genetic events in normal development and cancer that would not otherwise be possible
ongoing studies
• developmental gene signatures in other lung tumor types
• developmental signatures in other lung diseases– Interstitial lung disease/ Pulmonary fibrosis
possible clinical relevance
• correlate gene expression patterns of lung development genes with patient outcomes– Collaboration between JAX and Cancer Care of
Maine just funded by Maine Cancer Foundation to develop new models of lung cancer
• different transcriptional profiles may reflect a variety of strategies used by tumor cells for survival– New therapeutic targets?– Biomarkers?
