Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Airway epithelial cells are the first cells of the lungs to be exposed to the toxic agents contained within cigarette smoke. Accordingly, the response of these cells to this challenge is of considerable interest in the context of diseases in which cigarette smoke is a major aetiological factor.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
The sexually dimorphic expression of genes across 26 somatic rat tissues was using Affymetrix RAE-230 genechips. We considered probesets to be sexually dimorphically expressed (SDE) if they were measurably expressed above background in at least one sex, there was at least a two-fold difference in expression (dimorphism) between the sexes, and the differences were statistically significant after correcting for false discovery. 14.5% of expressed probesets were SDE in at least one tissue, with higher expression nearly twice as prevalent in males compared to females. Most were SDE in a single tissue. Surprisingly, nearly half of the probesets that were (SDE) in multiple tissues were oppositely sex biased in different tissues, and most SDE probesets were also expressed without sex bias in other tissues. Two genes were widely SDE: Xist (female-only) and Eif2s3y (male-only). The frequency of SDE probesets varied widely between tissues, and was highest in the duodenum (6.2%), whilst less than 0.05% in over half of the surveyed tissues. The occurrence of SDE probesets was not strongly correlated between tissues. Within individual tissues, however, relational networks of SDE genes were identified. In the liver, networks relating to differential metabolism between the sexes were seen. The estrogen receptor was implicated in differential gene expression in the duodenum. To conclude, sexually dimorphic gene expression is common, but highly tissue-dependent. Sexually dimorphic gene expression may provide insights into mechanisms underlying phenotypic sex differences.

Description
We stratified colorectal tumor samples using a new unsupervised, iterative method based on non-negative matrix factorization (NMF). The resulting five subtypes exhibited activation of specific signaling pathways, and significant differences in microsatellite status and tumor location. We could also align three CRC cell lines panels to these subtypes.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
In vitro prediction of developmental toxicity during early discovery phases of drug development has the potential to guide decision-making toward prioritizing candidate drugs that are less likely to later show teratogenicity in vivo. Such screening would reduce animal use in preclinical studies, including full-scale regulatory reproductive toxicology. we evaluate an assay format based on short-term toxicogenomic responses in pluripotent embryonic stem cells (ESC). We exposed attached undifferentiated cells of the mouse ESC cell line R1 for 6h to 10 known teratogenic and 9 non-teratogenic pharmaceutical drugs .
