Description
Increasing the understanding of the impact of changes in oncogenes and tumor suppressor genes is essential for improving the management of lung cancer. Recently, we identified a new mouse lung-specific tumor suppressor - the G-protein coupled receptor 5A (Gprc5a). We sought to understand the molecular consequences of Gprc5a loss and towards this we performed microarray analysis of the transcriptomes of lung epithelial cells cultured from normal tracheas of Gprc5a knockout and wild-type mice to define a loss-of-Gprc5a gene signature. Moreover, we analyzed differential gene expression patterns between Gprc5a knockout normal lung epithelial cells as well as lung adenocarcinoma cells isolated and cultured from tumors of NNK-exposed Gprc5a knockout mice.
Publication Title
A Gprc5a tumor suppressor loss of expression signature is conserved, prevalent, and associated with survival in human lung adenocarcinomas.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Genes differentially expressed among cells constituting an in vitro human lung carcinogenesis model consisting of normal, immortalized, transformed and tumorigenic bronchial epithelial cells were identified. The differentially expressed genes were then analyzed to determine their relevance to the gene expression patterns of clinical non-small cell lung cancer (NSCLC) samples as well as the clinical outcome of patients with this disease.

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
These samples have been analyzed for global alternative splicing variation on exon-level expression data using the FIRMA algorithm. We have identified and described transcriptome instability as a genome-wide, pre-mRNA splicing related characteristic of solid cancers.

- Affymetrix Yeast Genome S98 Array (ygs98)
Description
The highly conserved protein eIF5A found in archaea and all eucaryotes uniquely contains the posttranslationally formed amino acid hypusine. Despite being essential the functions of this protein and its modification remain unclear. To gain more insight into these functions temperature sensitive mutants of the human EIF5A1 were characterized in the yeast Saccharomyces cerevisiae.
Publication Title
Temperature-sensitive eIF5A mutant accumulates transcripts targeted to the nonsense-mediated decay pathway.

Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
Colorectal cancer is a heterogeneous disease molecularly characterized by inherent genomic instabilities, chromosome instability and microsatellite instability. In the present study we propose transcriptome instability as an analogue to genomic instability on the transcriptome level. Exon microarray data from two independent series of altoghether 160 colorectal cancer tissue samples was used for global alternative splicing detection using the FIRMA algorithm (aroma.affymetrix). The sample-wise amounts of these alternative splicing scores exceeding a defined threshold (deviating exon usage amounts) were summarized to provide the basis for description of transcriptome instability. This characteristic was shown to be associated with splicing factor expression levels and patient survival in both independent sample series.
