Transcriptional changes in response to oxidative stress in combination with temperature extremes in rice

ABSTRACT: Genome wide expression profiles of 10-day-old seedlings in response to prior exposure with OS followed by heat stress or cold stress as well simultaneous exposure to OS along with HS/CS was done to study the transcriptional changes in response to combination of stresses. 10-day old rice seedlings were used for experiments. Transcript profiling was done in 10-day old rice seedling following oxidative Stress prior to High Temperature Stress (PO_HS) or Low Temperature Stress (PO_CS) and Oxidative Stress during High Temperature Stress (DO_HS)/ during Low temperature stress (DO_CS). Unstressed seedlings were used as control. For each condition, three biological replicates were processed in a similar manner for the microarray analysis.

Targeted transcriptome analysis of the SigB regulon in Bacillus subtilis

Project description:Bacillus subtilis is exposed to a wide range of transitory stress and starvation conditions. Here we investigate the expression changes observed in the B. subtilis wild type strain 168 and its isogenic sigB mutant(BSM29) with respect to each stress condition tested. Gene expression was queried for the stress conditions: ethanol-, butanol-, osmotic- and oxidative stress, heat shock, low temperature growth, glucose as well as oxygen limitation. For butanol-, ethanol-, osmotic-, and oxidative stress as well as heat shock : time points (0min, 5min, 10min, 15min and 20min) ; for glucose limitation and oxygen limitation : time points (0min, 15min, 30min, 45min, 60min or 90min) and for low temperature growth, samples for recording of expression values were taken during mid-exponential growth at OD540 0.9 and 1.0.

Glucose Brassinosteroid Microarray Dark Grown Seedling

Project description:imbibed Col-0 seeds were sown on ? X MS medium supplemented with 0.8% agar and 1% sucrose. The plates were first exposed to continuous light for 12 h to stimulate germination and then wrapped with two layers of aluminum foil and placed in the growth chamber for 5 d. Once the plant material was uniformly germinated, the experimental conditions were applied. 5-d-old, dark-grown seedlings were washed seven times with sterile water followed by a wash with ? X MS liquid medium without sucrose to remove residual exogenous sugar and the plant material was kept in ? X MS liquid without sucrose in the dark for all subsequent steps. Cultures were shaken at 140 rpm at 22 C for 24 h and then treated with ? X MS without glucose or ½ X MS supplemented with BR (100 nM), glucose (3%), or glucose (3%) + BR (100 nM) for 3 h. Seedlings were harvested after 3h and preceded for RNA isolation and microarray analysis.

Analyzing cold tolerance mechanism in transgenic zebrafish (Danio rerio)

Project description:Low temperatures may cause severe growth inhibition and mortality in fish. In order to understand the mechanism of cold tolerance, a transgenic zebrafish Tg (smyd1:m3ck) model was established to study the effect of energy homeostasis during cold stress. The muscle-specific promoter Smyd1 was used to express the carp muscle form III of creatine kinase (M3-CK), which maintained enzymatic activity at a relatively low temperature, in zebrafish skeletal muscle. In situ hybridization showed that M3-CK was expressed strongly in the skeletal muscle. When exposed to 13M-BM-0C, Tg (smyd1:m3ck) fish maintained their swimming behavior, while the wild-type could not. Energy measurements showed that the concentration of ATP increased in Tg (smyd1:m3ck) versus wild-type fish at 28M-BM-0C. After 2 h at 13M-BM-0C, ATP concentrations were 2.16-fold higher in Tg (smyd1:m3ck) than in wild-type (P < 0.05). At 13M-BM-0C, the ATP concentration in Tg (smyd1:m3ck) fish and wild-type fish was 63.3% and 20.0%, respectively, of that in wild-type fish at 28M-BM-0C. Microarray analysis revealed differential expression of 1249 transcripts in Tg (smyd1:m3ck) versus wild-type fish under cold stress. Biological processes that were significantly overrepresented in this group included circadian rhythm, energy metabolism, lipid transport, and metabolism. These results are clues to understanding the mechanisms underlying temperature acclimation in fish. Gene expression in triplicate samples of m3ck-13M-BM-0C, m3ck-28M-BM-0C, wt-13M-BM-0C, and wt-28M-BM-0C was assessed. Twelve microarray experiments were performed, each with three fish.

Translation Inhibitors Cause Abnormalities in Ribosome Profiling Experiments

Project description:Ribosome profiling and high-throughput sequencing provide unprecedented opportunities for the analysis of mRNA translation. Using this novel method, several studies have demonstrated the widespread role of short upstream reading frames in translational control as well as slower elongation at the beginning of open reading frames in response to stress. Based on the initial studies, the importance of adding or omitting translation inhibitors, such as cycloheximide, was noted as it markedly affected ribosome coverage profiles. For that reason, many recent studies omitted translation inhibitors in the culture medium. Here, we investigate the influence of ranging cycloheximide concentrations on ribosome profiles in Saccharomyces cerevisiae and demonstrate that increasing the drug concentration can overcome some of the artifacts. We subjected cells to various manipulations and show that neither oxidative stress nor heat shock nor amino acid starvation affect translation elongation. Instead, the observations in the initial studies are the result of cycloheximide-inflicted artifacts. Likewise, we find little support for short upstream reading frames to be involved in wide-spread protein synthesis regulation under stress conditions. Our study highlights the need for better standardization of ribosome profiling methods. Ranging concentrations of cycloheximide and various stress contitions were tested with Ribo-seq

Impaired DNA damage metabolism promotes autoimmunity in TREX1 deficiencyÂ

Project description:Constitutive low level DNA damage is linked to innate immune activation. Hierarchical clustering of over 9000 transcripts revealed remarkably similar profiles in a patient with lupus erythematosus and a patient with AGS with up-regulation of genes involved in DNA damage signaling, p53-inducible genes, senescence-associated genes as well as up-regulation of interferon-stimulated genes. Transcriptional profiling of fibroblasts exposed to oxidative stress showed a marked up-regulation of genes involved in DNA replication/repair and replication licensing in TREX1-deficient cells compared to wild type cells suggesting massive replication stress. Comparison of transcriptional profiles of unstressed patient fibroblasts with wild type cells as well as fibroblasts exposed to oxidative stress

Variation of the genomic expression pattern after exposed to 17beta-estradiol in Japanese medaka (Oryzias latipes)

Project description:We assess gene expression patterns upon 17beta-estradiol (E2) exposure to Japanese medaka (Oryzias latipes) in order to appere the E2 effects using DNA microarray analysis. Larval medaka were exposed to 0, 3, 30 and 100 ng/L of E2 and concentration-dependent changes in gene expressions were examined using Agilent medaka DNA microarrays. At 7 day, fish were sacrificed and mRNA was extracted for gene expression analysis. In an effort to link gene expression changes to effects on higher levels of biological organization, sex characteristics, gonadal histology, GSI, and egg production and fertility were examined. In microarray experiments, the correlation factors between the controls were from 0.91 to 1.00 among control samples. We observed highly induced O. latipes Gene Indices (OLGI) related to egg-yolk protein such as vitellogenin and L-SF precursor etc., which were significantly affected in a concentration-dependent manner by E2 exposure. To clarify the function of expressed genes by E2 treatments, we selected statistically expressed genes from the microarray experiments. We found 190 genes and 72 genes which were statistically expressed in E2 treatment as induced and repressed genes, respectively. In the induced gene list, there were characteristic induced-genes in the categories of lipid metabolism, stress (oxidative stress, DNA and protein damage), and apoptosis with MAPK pathway. On the other hands, there were characteristic repressed genes in the categories of heat shock protein. Our result may suggest that gene expressions in yolk medaka is able to be used for detection of E2 effect by DNA microarray analysis. Larval medaka were exposed to 0, 3, 30 and 100 ng/L of E2 and concentration and time-dependent changes in gene expressions were examined using Agilent medaka DNA microarrays. At 7 day, three independent samples (one sample contained thirty whole medakas) were sacrificed and mRNA was extracted for gene expression analysis.

Surviving oxidative stress under iron starvation: an important lesson eminently learned by Aspergillus fumigatus in the human body

Project description:Aspergillus fumigatus has to cope with a combination of several stress types after colonisng the human body, and the interplay between the different stress responses can significantly influence the survival of this human pathogen during the invasion of the host organism. In this study, we examined how the H2O2 induced oxidative stress response depends on iron availability. Surprisingly, the applied H2O2 treatment, which induced only a negligible stress response in iron fed cultures, deleteriously affected the fungus under iron starvation and the majority of stress responses on the transcript level were characteristic only for the combined H2O2-iron starvation stress treatments. Our data suggest that the survival of the fungus highly depends on fragile balances, e.g. between siderophore and ergosterol productions or between economization on iron and production of essential iron containing proteins. The applied stress conditions also affected several processes related to virulence or drug susceptibility including secondary metabolism, zinc acquisition or antifungal drug transport. Our[It would be interesting to mention the antioxidative enzymes which are upregulated/increase in abundance under iron-depleting conditions] data clearly demonstrate that studying stress responses under single stress treatments is not sufficient to understand how fungal pathogens survive in a complex habitat and support the view that the evolutionary success of A. fumigatus as an opportunistic human pathogen is not the mere consequence of the productions of certain virulence factors. Importantly, this fungal pathogen is able to mount and coordinate high-complexity and outstandingly efficient responses to multiple and superpositioning stresses in various harsh habitats like the human body.
