Project description:As4.1 cells are a renin-expressing cell line commonly used to study the molecular regulation of the mouse renin gene. In the present study, the global gene expression profile was assessed in these cells under control conditions (VEHICLE) and after treatment with interleukin (IL) or hydrogen peroxide (HP), both of which negatively regulate mouse renin gene expression. Experiment Overall Design: For each experimental group, 2 separate cultures of As4.1 cells were used. Cells were treated with interleukin (IL), hydrogen peroxide (HP) or vehicle control (VEHICLE). Cellular RNA was prepared using conventional methods and quality was assessed using the Bioanalyzer 2100 (Agilent Technologies). All the microarray procedures were conducted at the University of Iowa DNA Core facility using standard Affymetrix protocols. In brief, approximately 5 ug of total RNA was used as input to a one-step amplification procedure to generate biotin-labeled RNA fragments for hybridization to the Affymetrix GeneChip Mouse Genome 430 2.0 array.

Project description:Oxidative stress caused by Menadione or Hydrogen peroxide in synchronized Saccharomyces cerevisiae cultures. Alpha factor synchronized cultures (0.2-0.4 OD), treated at the beginning of S phase (25 min after release from G1 arrest) with either 2 mM Menadione (MD) or 0.24 mM Hydrogen peroxide (HP), show cell cycle effects. Cells treated with MD arrested at G1. Cells treated with HP delayed at S and then, after removal of HP at 135 minutes , continued the cell cycle, only to arrest at G2/M. Growth was carried out in 30C with shaking (295 rpm). Two time course experiments were performed with each oxidative stress agent, designated as H2O2 and H2O2_II, MD and MD_II.

Project description:Gene expression profiling reveals multiple tissue-specific functionality of GSH. We evaluated the effects of GSH against hydrogen peroxide (HP) on HepG2 cells. We performed an untargeted whole-genome transcriptome analysis to explore functionality of GSH.

Project description:We report 293 Neisseria gonorrhoeae genes that show differential transcript abundance in response to 15 mM hydrogen peroxide treatment by RNA-Seq. We analyze the major physiological functional groups of genes affected by hydrogen peroxide exposure. In addition, we analyze which genes in our hydrogen peroxide-responsive set of genes belong to major known transcriptional regulatory circuits like iron homeostasis, anaerobiosis and others. We annotate which of the 293 hydrogen peroxide-responsive genes belong to operons. We annotate global transcriptional start sites and identify transcriptional start sites that are only present in hydrogen peroxide-treated bacteria. We validate the RNA-Seq data for a subset of representative genes by RT-qPCR and whether transcript abundance in this same subset of genes differs upon treatement with other reactive oxygen species encountered during infection, like organic peroxide, super oxide anion, and bleach.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:To elucidate the mechanisms underlying epithelial homeostasis, we explored molecules that might serve as M-bM-^@M-^\dangerM-bM-^@M-^] signals in mediating epithelial regeneration with microarray. We hypothesize that soluble factors may have been released from damaged cells to stimulate the proliferation of surviving epithelial cells. In elucidating the mechanism of dying cell-to-surviving cell communication using normal rat kidney NRK-52E epithelial cells, we observed gene expression profiles in these cells after the induction of cell death using hydrogen peroxide. The results demonstrated up-regulation of Interleukin-6, Heme oxygenase-1 and Hypoxia inducible factor-1 alpha in dying cells. Global gene expression changes were measured after induction of cell death in NRK-52E cells after incubation with hydrogen peroxide. Hydrogen peroxide (0, 0.003, 0.006, 0.009% in DMEM) was teated for 1 hour. After wash with PBS, cells were incubated with non-serum DMEM for 12 hours.

Project description:Gene expression changes in response to aging, hyperoxia, hydrogen peroxide, ionizing radiation, and heat stress were compared using microarrays. While aging shared features with each stress, aging was more similar to the stresses most associated with oxidative stress (hydrogen peroxide, hyperoxia, ionizing radiation) than to heat stress. Aging is associated with down-regulation of numerous mitochondrial genes, including electron-transport-chain (ETC) genes and mitochondrial metabolism genes, and a sub-set of these changes was also observed upon hydrogen peroxide stress and ionizing radiation stress. Aging shared the largest number of gene expression changes with hyperoxia. The extensive down-regulation of mitochondrial and ETC genes during aging is consistent with an aging-associated failure in mitochondrial maintenance, which may underlie the oxidative stress-like and proteotoxic stress-like responses observed during aging.
