Transcriptional profiling of Arabidopsis thaliana grown under arsenate stress

ABSTRACT: We examined the changes in gene expression in Arabidopsis thaliana grown under arsenate stress. The transcriptional profiling reveals antioxidant activity and repression of the phosphate starvation response. Keywords: dual label, stress response This experiment included a comparison of three biological replicate controls against three biological arsenate-stressed replicates with a dye-swap technical replicate for a total of six microarray slide hybridizations.

<h4>Background</h4>Arsenic is toxic to plants and a common environmental pollutant. There is a strong chemical similarity between arsenate [As (V)] and phosphate (Pi). Whole genome oligonucleotide microarrays were employed to investigate the transcriptional responses of Arabidopsis thaliana plants to As (V) stress.<h4>Results</h4>Antioxidant-related genes (i.e. coding for superoxide dismutases and peroxidases) play prominent roles in response to arsenate. The microarray experiment revealed induc ...[more]

Identification of mRNAs modulated by knockdown of CD24

Project description:We endeavored to identify factors and pathways regulated by CD24 and to obtain leads regarding the mechanism by which CD24 inhibited the invasiveness and metastasis of pancreatic cancer cells by performing cDNA microarray analysis on S2-013 CD24 RNAi clones and control clones. The group of genes showing increased expression was mainly comprised of genes for molecules with functions related to RNA metabolism, transcription factors, proteases, and molecules involved in embryonic development and cell growth. The set of genes downregulated by knockdown of CD24 included the target mRNAs of a phosphorylation-dependent endoribonuclease G3BP that interacted with CD24. The target mRNAs of G3BP were identified in GSE17056. These results suggested that CD24 inhibited the RNase activity of G3BP, and that a function of CD24 was to inhibit the degradation of specific mRNAs. Transcripts upregulated or downregulated by knockdown of CD24 were identified through expression profiling of a total of 12,135 genes in S2-013 CD24 RNAi clones compared to control clones. Before labeling with Cy5 or Cy3, total RNA from two S2-013 CD24 RNAi clones were mixed and total RNA from two control clones were mixed. The supplementary files 'GSE17055_higher_siCD24.txt' and 'GSE17055_higher_control.txt' list the differentially expressed genes.

Mismatch oligonucleotides in yeast

Project description:Tiled 10kb region centered around ACT1 gene (YFL039C, CHROMOSOME 6 @ coords 48760-59195), double-stranded, 36mers at 1bp spacing, with mismatches and deletions; also tiled 6 genes of interest (YBL092W, YGR155W, YOL040C, YOR312C, YMR242C, YLR229C), coding strand only, 36mers at 1bp spacing, with some mismatches and deletions Keywords: Mismatch hybridization experiment Tiled perfect match and various designs of mismatch oligonucleotide for several yeast genes. Goal was to observe the influence of various MM types on hybridization behavior in yeast and compare it to human (see related slide).

Mismatch oligonucleotides in human and yeast

Project description:Background Mismatched oligonucleotides are widely used on microarrays to differentiate specific from nonspecific hybridization. While many experiments rely on such oligos, the hybridization behavior of various degrees of mismatch (MM) structure has not been extensively studied. Here, we present the results of two large-scale microarray experiments on S.cerevisiae and H.sapiens genomic DNA, to explore MM oligonucleotide behavior with real sample mixtures under tiling-array conditions. Results We examined all possible nucleotide substitutions at the central position of 36-nucleotide probes, and found that nonspecific binding by MM oligos depends upon the individual nucleotide substitutions they incorporate: C->A, C->G and T->A (yielding purine-purine mispairs) are most disruptive, whereas A->X were least disruptive. We also quantify a marked GC skew effect: substitutions raising probe GC content exhibit higher intensity (and vice versa). This skew is small in highly-expressed regions (Â±0.5% of total intensity range) and large (Â±2% or more) elsewhere. Multiple mismatches per oligo are largely additive in effect: each MM added in a distributed fashion causes an additional 21% intensity drop relative to PM, three-fold more disruptive than adding adjacent mispairs (7% drop per MM). This SuperSeries is composed of the following subset Series: GSE13172: Mismatch oligonucleotides in human GSE13174: Mismatch oligonucleotides in yeast Refer to individual Series

Project description:Bi-sex male and female Schistosoma mansoni worms were isolated from mice 7-weeks post-infection. Bi-sex male material or female material was compared in a direct bimodal comparison to single-sex male or female material. Two independent biological batches of both bi- and single-sex males were used. One batch of single-sex female material was used in comparisons to three independent biological batches of bi-sex female material. A dye-swap hybridization was performed for each bimodal comparisons in turn.

Transcription profiling of Fusarium head blight resistance in Sumai-3 and two susceptible NILs

Project description:Microarray gene expression analysis were performed to identify genes responding to Fusarium graminearum inoculation and genes that show a differential regulation between the resistant c.v. Sumai-3 and the susceptible near isogenic lines. Sumai-3 is a Chinese wheat cultivar, the most commonly used source of resistance to Fusarium head blight (FHB) disease. NIL-3 and NIL-4 are near isogenic lines susceptible to FHB and are derived from a cross between Sumai-3 and Chuan980, a susceptible wheat cultivar, followed by seven generations of marker assisted backcrossing with the recurrent parent Sumai-3 and selection for FHB susceptibility in each generation by artificial inoculation with F. graminearum. A combination of DNA markers including simple sequence repeats (SSRs) and amplified fragment length polymorphisms (AFLPs) were used to screen for DNA polymorphisms between Sumai-3 and its susceptible NILs. Polymorphic markers were mapped using a mapping population. The analysis indicated 7 polymorphisms between the susceptible NILs and the resistant Sumai-3. The analysis indicated that NIL-3 differs from Sumai-3 at chromosome 3BS and NIL-4 differs from Sumai-3 at chromosome 2AL region.
