- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Iron is essential for many cellular processes and is required by bacteria for replication. To acquire iron from the host, pathogenic Gram-negative bacteria secrete siderophores, including Enterobactin (Ent). However, Ent is bound by the host protein Lipocalin 2 (Lcn2), preventing bacterial reuptake of aferric or ferric Ent. In two experiments we treated A549 (lung cancer cell line) cells with Lcn2, Ent, and iron, alone and in combination. In experiment 1, biological duplicates of 4 conditions were used: PBS control, Lcn2, Lcn2+Ent, and Lcn2+Ent+iron. In experiment 2, 4 biological replicates of 4 conditions were used: PBS control, Ent, iron, and Ent+iron. Targets made from the samples were hybridized to Affymetrix Human Gene 1.0 ST arrays to measure transcript abundances. The RMA algorithm was used to estimate transcript levels. Replicate samples were exchangeable, so we fit one-way ANOVA models to log2-transformed data separately to each experiment, and tested for pairwise differences between groups in each experiment, as well as asking if the Ent vs. PBS differences were larger or smaller than the Ent+iron vs. iron differences (Ent by iron interactions). We report results for 29096 probe-sets that were not annotated as positive or negative controls on the array. A supplementary Excel workbook is provided that contains the estimated expression level, some probe-set annotation, and simple statistical analysis for each probe-set. It may be convenient for some users, however obtaining newer probe-set annotation may be advisable.

- Affymetrix Mouse Gene 2.1 ST Array (mogene21st)
Description
We treated 6-8 week old mice that had floxed alleles of both Apc and Pten (for both alleles in each case) that also carry an Ovgp1-iCre-ERT2 transgene, with one of two treatments; a third group received neither treatment. The Ovgp1-iCre-ERT2 expresses Cre recombinase fused to a tamoxifen-inducible fragment of the estrogen receptor, in tissues where the Ovgp1 gene (oviductal glycoprotein 1) is expressed, which is almost exclusively in mouse oviductal epithelium (equivalent to human fallopian tube epithelium = FTE). Treating the mice with tamoxifen permits the Cre recombinase to enter the cell nucleus and inactivate the Apc and Pten genes. Six of the mice were treated with intraperitoneal injection of tamoxifen (0.1g/kg of body weight) dissolved in corn oil on days 1 and 3 and developed oviductal tumors (OdT) yielding 6 of the samples. Four mice (yielding 5 samples) were instead injected with 50 million plaque-forming units of replication-incompetent AdCre into both ovarian bursal cavities on day 1, which inactivated Apc and Pten in the ovarian surface epithelium (OSE), and lead to ovarian tumors (OT). Ovaries were also harvested from four untreated 6-8 week old mice with the same genotype, with two ovaries from each mouse comprising one control sample. RNA was purified from tumor or normal tissue, and targets for Affymetrix arrays synthesized from the mRNAs. We used Affymetrix Mouse Gene 2.1 ST arrays, which hold 41345 probe-sets, but we largely analyzed just those 25216 probe-sets that were mapped to Entrez gene IDs. Raw data was processed with Robust Multi-array Average algorithm (RMA). Data is log2-transformed transcript abundance estimates. We fit a one-way ANOVA model to the three groups of samples. We supply a supplementary excel workbook that holds the same data as the data matrix file, but also holds the probe-set annotation at the time we analyzed the data, and some simple statistical calculations, which select subsets of the probe-sets as differentially expressed. Consumers should consider obtaining more up-to-date probe-set annotation for the array platform. We also provide supplementary excel files that show our simple analysis of GSE6008, which consists of 99 human ovarian tumor samples of 4 types, and 4 normal ovary samples, where we fit an ANOVA model to the 5 groups. In yet another supplementary file we show the correlation between each human tumor and mouse tumor, where we correlate the difference in log2-transformed values of each tumor from the average of the normals for the same species, for just those genes that were 1-to-1 best homologs according to build 68 of NCBI's Homologene, in order to see how much the human tumors resemble the mouse tumors.

- Affymetrix Mouse Gene 1.1 ST Array (mogene11st)
Description
In order to investigate genes regulated by Wnt/Beta-catenin-signaling in immortalized mouse adrenocortical cells, we treated a pair of ATCL7 cell cultures, one with BIO, a small molecule mimicking Wnt/Beta-catenin-signaling, the other with a control treatment. We repeated this 3 additional times resulting in 4 pairs of samples. The Wnt/beta-catenin pathway is not basally active in ATCL7 cells, nor do these cells appear to contain any mutations in the Wnt/Beta-catenin pathway. ATCL7 cells were grown under standard conditions at 37C in a humidified incubator containing 5% CO2. 250,000 ATCL7 cells per sample were treated with 0.5uM BIO (6-Bromoindirubin-3'-oxime) or 0.01% DMSO (v/v) for 24 hours, in DMEM:F12 growth media containing 100U/mL pencillin/streptomycin, 1X insulin-transferrin-selenium-X, 0.025% fetal bovine serum and 0.025% horse serum. Cells were harvested and RNA was extracted using an RNeasy Plus Mini Kit (Qiagen). Biotinylated cDNA were prepared according to the Ambion WT kit protocol from 250 ng total RNA (GeneAtlas WT Expression Kit User Manual P/N 702935 Rev. 3). We assayed the targets with Affymetrix Mouse Gene ST 1.1 strip arrays. We modeled the data using paired T-tests for each probe-set. We also supply a supplementary file holding the data and some statistical analysis, as well as probe-set annotation that we used at that time (users may wish to obtain new annotation though). We analyzed only 28944 probe-sets with category "main", "---", and "flmrna->unmapped" according to Affymetrix annotation.

Description
We sought to determine which gene transcripts are enriched in Wnt-responsive adrenocortical mouse cells compared to the entire adrenocortical mouse cell population in vivo. To this end, we employed transgenic reporter mice that label Wnt-responsive cells with GFP expression (TCF/Lef:H2B-GFP mice) or label all adrenocortical cells with GFP expression (Sf1:eGFP mice). GFP-positive adrenocortical cells were obtained from 6-week-old male TCF/Lef:H2B-GFP mice and Sf1:eGFP mice independently. 10 adrenals per genotype per sort were minced and digested by incubation in DMEM:F12 containing 0.1% collagenase/ 0.01% DNaseI solution for 1 h at 37C. A single cell suspension was obtained following mechanical dispersion, filtration through a 40 micron nylon cell strainer, centrifugation at 1500rpm for 5 min followed by re-suspension in sterile 1X PBS containing 10% cosmic calf serum and 10g/mL Propidium iodide. 10,000-50,000 viable GFP-positive cells were isolated via FACS using a BD FACSAria III cell sorter. RNA was extracted using an RNeasy Micro Kit (Qiagen) from 4 independent sorts per genotype. cDNA were prepared according to the NuGen WT-Pico V2 kit protocol from 5 ng total RNA (Ovation PicoSL WTA System V2 P/N 3312). Biotinylated single-stranded cDNA were prepared from 3ug of cDNA (Encore Biotin Module P/N 4200-12, 4200-60, 4200-A01). Targets were assayed on the Mouse Gene ST 1.1 strip arrays using the Affymetrix Gene Atlas system (software version 1.0.4.267). One TCF/Lef:H2B-GFP array was deemed low-quality and discarded. Two-sample T-tests were used to compare the two groups of samples. We also supply a supplementary file holding the data and some statistical analysis, as well as probe-set annotation that we used at that time (users may wish to obtain new annotation though). We analyzed only 28944 probe-sets with category "main", "---", and "flmrna->unmapped" according to Affymetrix annotation.

Description
Nave CD44-lo/CD62L-hi/CD8+ T cells from C3H.SW mice were compared to CD44-hi/CD82L-lo/CD8+ effector memory T cells and CD44-lo/CD62L-hi/CD8+ postmitotic T cells, using 3 biological replicates of each type of sample. The later two cells types were highly purified at day 14 after transplantation from GVHD B6/SJL mice receiving donor C3H.SW mouse-derived naive CD44-lo/CD62L-hi/CD8+ T cells and T cell-depleted bone marrow. Recipient mice had first been lethally irradiated at a dose of 10Gy in two fractions. This is a MHC-identical minor histocompatibility antigen-mismatched mouse GVHD model of human allogeneic hematopoietic stem cell transplantation. Naive T cell samples were from pools of 2 mice each, while effector memory and postmitotic T cell samples were purified from pools of T cells from 4 mice each. After RNA extraction and cleanup, biotin labeled cRNA was prepared from 600 ng total RNA, using two rounds of in vitro transcription, and hybridized to Affymetrix Mouse Genome 430A 2.0 arrays using standard techniques.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We mated mice with floxed alleles of both Apc and Pten, to mice with floxed alleles for Arid1a, to obtain female mice with both copies of all three genes floxed. At 7 to 8 weeks of age the right ovarian bursal cavites of the mice were injected with 50 million plaque-forming units of adenovirus expressing Cre recombinase, which causes the floxed genes to be knocked out. Tumor tissue from 3 mice for each group was obtained at necropsy, RNA purified, and targets for Affymetrix arrays synthesized from the mRNAs. We used Affymetrix Mouse Genome 430 2.0 arrays, which hold 45101 probe-sets. Raw data was processed with Robust Multi-array Average algorithm (RMA). Data is log2-transformed transcript abundance estimates. We performed T-tests to compare the 3 vs 3 arrays. We supply a supplementary excel workbook that holds the same data as the data matrix file, but also holds the probe-set annotation at the time we analyzed the data, and some very simple statistical calculations, which select subsets of the probe-sets as differentially expressed. Consumers should consider obtaining more up-to-date probe-set annotation for the array platform. We have also supplied a second supplementary tar archive holding software and files to 1) perform permutation testing of the probe-set selection in order to estimate false discovery rates for the probe-sets we selected as differentially expressed, 2) perform enrichment testing of GO terms, and 3) to perform enrichment testing of KEGG pathways and 3000 curated gene sets from version 4 of the Molecular Signatures Database (MSigDB). The software is in "C".
