The early blood vessels of the embryo and yolk sac in mammals develop by aggregation of de novo forming angioblasts into a primitive vascular plexus, which then undergoes a complex remodeling process. Angiogenesis is also important for disease progression in the adult. However, the precise molecular mechanism of vascular development remains unclear.

View SamplesWe performed global scale microarray analysis to identify detailed mechanisms by which nonpermissive temperature induces cell growth arrest and differentiation in astrocyte RCG-12 cells harboring temperature-sensitive simian virus 40 large T-antigen by using an Affymetrix GeneChip system. Astrocyte RCG-12 cells used in this study were derived from primary cultured rat cortical glia cells infecting with a temperature-sensitive simian virus 40 large T-antigen. Although the cells grew continuously at the permissive temperature, the nonpermissive temperature led to cell growth arrest and differentiation. Of the 15,923 probe sets analyzed, nonpermissive temperature differentially expressed 556 probe sets by >2.0-fold.

View SamplesProstate cancer is the most common cancer in men. We identified that miR-29 family is the most androgen-responsive miRNA in hormone-refractory prostate cancer cells. For the screening of miR-29b target, we performed microarray analysis in two prostate cancer cells. Because TET2 is the primary target of miR-29 family by our analysis, we also performed TET2 signaling by microarray.

View SamplesSaccharomyces cerevisiae is exposed to freeze-thaw stress in commercial processes including frozen dough baking. The cell viability and fermentation activity after freeze-thaw were dramatically decreased due to freeze-thaw injury. Because freeze-thaw injury involves complex phenomena, the mechanisms of it are not fully understood. We attempted to analyze the mechanisms of freeze-thaw injury by indirect gene expression analysis during post-thaw incubation after freeze-thaw treatment using DNA microarray profiling. The results showed that a high frequency of the genes involved in the homeostasis of metal ions were up-regulated depending on the freezing period. The phenotype of the deletion mutants of the up-regulated genes extracted by indirect gene expression analysis was assessed. The deletion strains of the MAC1 and CTR1 genes involved in copper ion homeostasis exhibited freeze-thaw sensitivity, suggesting that copper ion homeostasis is required for freeze-thaw tolerance. Supplementation with copper ions during post-thaw incubation increased intracellular superoxide dismutase activity. Inverse correlated with intracellular superoxide dismutase activity, intracellular levels of reactive oxygen species were decreased. Moreover, cell viability increased by supplementation with copper ions under specific assessment conditions. This study suggested that insufficiency of copper ion homeostasis may be one of the causes of freeze-thaw injury.
