TranscriptomicsGenetic architecture of murine skin inflammation and tumor susceptibility
Gene expression in self-renewing epithelial tissues is controlled by cis- and trans-activating regulatory factors that mediate responses to exogenous agents capable of causing tissue damage, infection, inflammation, or tumorigenesis. We used network construction methods to analyze the genetic archi...

TranscriptomicsProgressive genomic instability in the FVB/KrasLA2 mouse model of lung cancer
Alterations in DNA copy number contribute to the development and progression of cancers and are common in epithelial tumors. We have used array Comparative Genomic Hybridization (aCGH) to visualize DNA copy number alterations across the genomes of lung tumors in the KrasLA2 model of lung cancer. C...

TranscriptomicsExpression analysis of superior cervical ganglion from backcrossed TH-MYCN transgenic mice
Neuroblastoma susceptibility in TH-MYN mice is heavily influence by mouse strain background. We have combined linkage analysis of tumor susceptibility with expression QTL analysis of superior cervical ganglia (pure peripheral symptathetic nervous tissue) to identify genes underlying tumor formation...

TranscriptomicsMurine microenvironment metaprofiles associate with human cancer etiology and intrinsic subtypes
We developed a mouse model that captures radiation effects on host biology by transplanting unirradiated Trp53 null mammary tissue to sham or irradiated hosts. Gene expression profiles of tumors that arose in irradiated mice are distinct from those that arose in naM-CM-/ve hosts. Host irradiation in...

TranscriptomicsNormal mouse skin lacking Hras
Oncogenic activating mutations in Ras genes are among the most common drivers of human disease. Treating mouse skin with the chemical carcinogen DMBA induces a characteristic mutation in Hras at codon 61. To understand how skin responds to a constitutive lack of Hras, we generated a cohort of Hras k...

TranscriptomicsGene expression architecture of mouse dorsal and tail skin reveals functional differences in inflammation and cancer: TPA time course
Gene expression levels in normal tissues can differ substantially between individuals, due to inherited polymorphisms acting in cis or trans. Analysis of this variation across a population of genetically distinct individuals allows us to visualize a network of co-expressed genes under normal homeost...

TranscriptomicsIdentification of Hipk2 as a central regulator of white fat development
Homeodomain interacting protein kinase 2 (Hipk2) has previously been implicated in control of several transcription factors involved in embryonic development, apoptosis, cell proliferation and tumour development1–3. Analysis of gene expression in tissues from genetically heterogeneous mouse or human...

TranscriptomicsNetwork Analysis of Skin Tumor Progression Identifies a Rewired Genetic Architecture Affecting Inflammation and Tumor Susceptibility (aCGH)
Background: Germline polymorphisms can influence gene expression networks in normal mammalian tissues and can affect disease susceptibility. We and others have shown that analysis of this genetic architecture can identify single genes and whole pathways that influence complex traits including inflam...

TranscriptomicsshRNAi profiling of human MDA-MB-231 cells expressing anti-p53 (shp53) short-hairpin RNAs treated with TFGbeta or control
TGFβ ligands act as tumor suppressors in early stage tumors but are paradoxically diverted into potent prometastatic factors in advanced cancers. The molecular nature of this switch remains enigmatic. We now show that TGFβ-dependent cell migration, invasion and metastasis are empowered by mutant-p...

TranscriptomicsThe genetics of splicing in neuroblastoma
Regulation of mRNA splicing is a critical and tightly regulated cellular function, underlying the majority of proteomic diversity in our genomes. While disruption of this process is common in disease, the basic genetic complexity of alternative splicing in vivo remains poorly understood. To delinea...
