Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Cold atmospheric pressure plasma (CAP) is known as a source of biologically active agents, such as reactive oxygen species (ROS) and reactive nitrogen species (RNS). Recent medical investigations have focused on applying CAP to cancer treatment. There is also growing evidence that exposure of cells to CAP or CAP-activated medium induces apoptosis in cancer cells, and ROS and/or RNS are considered to be effective agents to CAP-induced apoptosis. More recently, we demonstrated that Ar-CAP or Ar containing 2.5 % of N2 (Ar-N2-CAP) significantly induced apoptosis in human lymphoma U937 cells. However, a detailed molecular mechanism underling the induction of apoptosis by CAP in cancer cells is unclear.

Description
In order to test the hypothesis that fibroblasts from different tissues are phenotypically distinct from one another, we have subjected tendon, skin and corneal fibroblasts of fetal mouse to mechanical stimulation by fluid flow and analyzed the transcriptional responses of the cells using Affymetrix MOE430 chip set containing two arrays MOE430A and MOE430B.

Description
Saccharomyces 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.

Description
Recent research hints at an underappreciated complexity in pre-miRNA processing and regulation. Global profiling of pre-miRNA and its potential to increase understanding of the pre-miRNA landscape is impeded by overlap with highly-expressed classes of other non-coding RNA. Here we present a dataset excluding these RNA before sequencing through locked nucleic acids (LNA), greatly increasing pre-miRNA sequence counts with no discernable effects on pre-miRNA or mature miRNA sequencing. Analysis of profiles generated in total, nuclear, and cytoplasmic cell fractions reveals pre-miRNAs are subject to a wide range of regulatory processes involving loci-specific 3'- and 5'-end variation entailing complex cleavage patterns with co-occurring polyuridylation. Additionally, examination of nuclear-enriched flanking sequences of pre-miRNA, particularly those derived from polycistronic miRNA transcripts, provides insight into miRNA and miRNA-offset (moRNA) production. Our findings point to particularly intricate regulation of the let-7 family, introduce novel and unify known forms of pre-miRNA regulation and processing, and shed new light on the byproducts of miRNA processing pathways. none provided
