Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Activation of telomerase often endows cancer cells, but rarely normal somatic cells, with immortality. Especially, fetal lung fibroblasts are known to be hardly immortalized by TERT overexpression. We here established an immortal non-transformed lung fibroblast cell line only by TERT transfection, as well as an immortal transformed cell line by transfection of TERT and SV40 early antigens. Comparing the expression profiles of these cell lines with those of mortal cell strains with elongated lifespan after TERT transfection, 51 genes, including 19 upregulated and 32 downregulated, were explored to be the candidates responsible for regulation of cellular proliferation of lung fibroblasts. These included the genes previously reported to be involved in cellular proliferation, transformation, or self-renewal capacity, and those highly expressed in lung tissues obtained from patients with idiopathic pulmonary fibrosis or hypersensitivity pneumonitis. This set of lung fibrobrast cell lines/strains of identical genetic background with different proliferative capacity, mortal and immortal non-transformed fibroblasts may become useful model cells for research on lung fibroblast growth regulation and the candidate genes explored in this study may provide promising biomarkers or molecular targets of pulmonary fibrosis.

Description
Utilizing C. elegans as a model of mitochondrial dysfunction provides insight into cellular adaptations which occur as a consequence of genetic alterations causative of human disease. We characterized genome-wide expression profiles of hypomorhpic C. elegans mutants in nuclear-encoded subunits of respiratory chain complexes I, II and III.

Description
Screening for genes regulated by Etv2 within Flk-1+/PDGFRa+ ES derived mesoderm.Microarray analysis performed to screen for the candidate genes regulated by Etv2. TT2 ES cells differentiated on OP9 feeder cells were sorted using Flk-1 and PDGFRa antibodies.Gene expressions from these two populations were compared.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
Deregulated retinal angiogenesis directly cause vision loss in many ocular diseases, such as diabetic retinopathy and retinopathy of prematurity. To identify endothelial-specific genes expressed in angiogenic retinal vessels, we purified genetically labeled endothelial cells from Tie2-GFP transgenic mice and performed gene expression profiling using DNA microarray. To find out genes associated with angiogenesis, comparisons of microarray data were carried out between GFP-negative non-endothelial retinal cells and GFP-positive retinal endothelial cells in angiogenic P8 retina.
