Project description:Wild-type and dF508 CFTR mutant human bronchial epithelial cells were uninfected or infected for 3 hours at an MOI of 30-50 with P.aeruginosa strain PAO1. Each cell line was tested in 4 replicates. Each replicate consists of 4 data sets: 2 sets of duplicate spots on 2 arrays. The two arrays in each replicate were dye-swapped pairs where the opposite dye was used for each sample in the second array. I have called replicates "Rep1, Rep2..." etc. I have indicated duplicates from the same slide as eg."Slide1A and Slide1B" I have refered to the two arrays used in each replicate as "Slide1" and "Slide 2".

Project description:In order to understand the function of the Tra1p transcription factor we identified potentially Tra1p-regulated genes by comparison of transcript abundance in aerial mycelium of the tra1- mutant and the parental strain 70-15. Two-condition experiment, wild-type vs. TRA1-deleted mutant. 4 biological replicates with dye-swaps. Each microarry slide had 2 arrays with 44k spots (22k spots printed twice). Thus, rep1 and rep2 are technical replicates of the same biological sample (derived from one raw data file).

Project description:The data in this series forms the basis for the analysis presented in the above named paper. In this study, we used cDNA microarrays to ask if changes in gene expression are observed in response to a dietary shift in Drosophila melanogaster, a dietary generalist. Methods: Flies used in this study were derived from a multifemale collection at Iraklion, Crete, Greece, in August 2002 and reared in the laboratory for several generations. Three replicates were performed. At the start of each replicate, we collected 300 newly eclosed adults, separated them by sex, and stored them at low density in shell vials with standard cornmeal media for 3 days. Sexually mature males and females were placed together and allowed to mate. Mated females were allowed to oviposit overnight in chambers containing cornmeal medium filled Petri dishes (http://flyfood.arl.arizona.edu/cornmeal.php3). Hatching first instar larvae were reared for 36 hours on cornmeal medium in Petri dishes and then transferred to one of two conditions: 1) a control Petri dish consisting of cornmeal medium, or 2) an experimental Petri dish containing pure mashed banana. After 24 hours, larvae were plucked from these dishes, washed, transferred to microcentrifuge tubes in groups of 20, and flash frozen in liquid nitrogen. All samples were stored at -80C until RNA extraction. RNA was extracted from each tube using a Qiagen RNeasy kit (Qiagen, Inc., standard protocol). We used cDNA microarrays printed by the Genetic Analysis and Technology Core Custom Microarray Facility at the University of Arizona to assess expression levels. Printing material was amplified from BDGP Unigene library v1.0 containing 6K ESTs. Products were purified using Millipore Multiscreen filtration plates and re-suspended in 50%DMSO solution. Each product was printed in triplicate on Corning GAPSII aminosilane slides using a Virtek Chipwriter PRO microarray spotter. Between 10-15 micrograms of RNA were used for each reaction. RNA was reverse transcribed and labeled with one of two fluorescent dyes, Cy3 or Cy5 (details of protocol at http://gatc.arl.arizona.edu/Services/Microarray/aminoallyllabelling.html). Hybridization was completed on a Genomic Solutions Gentac automated hybridization station. Labeled material was allowed to hybridize to the array for 16 hours at 60°C. Wash conditions were: 1) low stringency wash twice at 50°C for 40seconds (1X SSC/ 0.2% SDS), 2) medium stringency wash twice at 42°C for 40 seconds ( 0.1X SSC/ 0.2% SDS), 3) high stringency wash twice at 42°C for 40 seconds (0.1X SSC). Hybridized arrays were scanned using the Applied Precision ArrayworxE slide scanner. We performed three independent hybridizations and three dye flips for a total of six arrays (2 treatments x 2 dyes x 3 replications = 12 samples, for 6 arrays). Each replicate consisted of an independent biological sample isolated on separate days. Identification of series: There are 18 series in this experiment. The second number in each series record represents the slide number (there were six slides used in this experiment). The third number in each series record represents the set on a given slide. For instance, for series record 331_2_1, these data correspond to slide 2, set 1. Each slide has 3 series numbers assoicated with it, representing set 1,2, or 3 on the slide. Each slide was paired with another in a "dye flip" experiment; thus, slides 2 and 3 were paired, slides 25 and 28 were paired, and slides 29 and 30 were paired.

Project description:A microarray analysis was conducted to investigate transcriptional differences between strains of Paxillus involutus that show different abilities in formation of ectomycorrhizal associations with birch (Betula pendula). Our goal was to identify genes that showed differential regulation from comparing incompatible (not mycorrhiza forming) (Nau) and compatible (mycorrhiza forming) strains (ATCC200175 and Maj) of P. involutus, in association with birch. The entire design involved 11 slides (ME01-M11), 13 labelled extracts, and 3 biological replicates (Rep1-Rep3). The experiment was designed as a simple loop (all-pairwise comparisons) of all three strains including dye-swap, biological and technical replication. Additional information: In our pre-processing of data, 4 channels were excluded for further analyses due to overall poor quality and are listed below. Slide ME03, Cy5(635nm) (strain Nau, Rep2) Slide ME04, Cy5(635nm) (strain Nau, Rep2) Slide ME06, Cy5(635nm) (strain Maj, Rep2) Slide ME09, Cy5(635nm) (strain Nau, Rep2)

Project description:The fungal pathogen Sclerotinia sclerotiorum infects a broad range of dicotyledonous plant species and is the causative agent of stem rot in Brassica napus. To elucidate the mechanisms underlying the defense response, we studied the patterns of gene expression in a partially resistant variety of ZhongYou 821 (ZY821) and a susceptible line from Westar over five time points, 6, 12, 24, 48, and 72 hours post-inoculation (hpi) using a B. napus oligonucleotide microarray. Maximum differential gene expression was observed at 48 hpi in both genotypes with ZY821 responding more quickly than Westar. Specific sets of genes exhibited higher levels of expression at the earlier stages of the infection (6-12 hpi), including genes encoding defense-associated proteins such as chitinases, glucanases, osmotins and lectins and genes encoding transcription factors belonging to the zinc finger, WRKY, AP2, and MYB classes. Genes encoding enzymes involved in JA, ethylene, and auxin synthesis were induced in both genotypes, as were those for gibberellin degradation. Changes in metabolic pathways affecting carbohydrate and energy metabolism appeared to be directed toward shuttling carbon reserves to the TCA cycle. Genes involved in glucosinolate and phenylpropanoid biosynthesis were highly up-regulated suggesting that secondary metabolites are also important components of the response to S. sclerotiorum in B. napus.

Project description:Cultures of Y. pestis Kimberley53 virulent strain were exposed to different concentrations of ciprofloxacin (including 0.016 µg/ml representing the strains' MIC value) for various time periods. Total RNA samples were extructed and used for cRNA synthesis and labelling (using Cy3-CTP for the treated samples and Cy5-CTP for the non-treated sample in one biological experiment and dye swap for the 2nd replicate of independent biological experiment). 8 Labeled cRNA samples were hybridized to custom made Agilent 8x15K slide (each slide represent 1 time point). Goal: Identifing alterations in gene expression profile which correlates with the ciprofloxacin induced growth inhibition. Those altered mRNA transcrips will be used as a markers for the development of rapid molecular Antibiotic Susceptibility Test.

We now report the first use of this technology for analysis of gene expression in filarial worms. The slide array (comprised of 65 mer oligos representing 3569 EST clusters) was spotted with sequences selected from the extensive Brugia malayi EST database (http://nema.cap.ed.ac.uk/nematodeESTs/nembase.html#Annotation). Arrays were hybridized with male and female cDNA and developed with Cy5- and Cy3-fluorescent 3DNA capture reagents.
