Transcription profiling of human adrenocortical carcinomas (33), adenomas (22), and normal adrenal cortex (10)

ABSTRACT: Human samples of 33 adrenocortical carcinomas, 22 adrenocortical adenomas, and 10 normal adrenal cortex samples, each from a different patient, had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. Experiment Overall Design: Two supplementary files are attached below. The Adrenocortical_logs.xls file shows the log-transformed probe-set values and the results of a statistical analysis for each probe-set. The Readme file describes the columns of this log file.

<h4>Purpose</h4>Our understanding of adrenocortical carcinoma (ACC) has improved considerably, yet many unanswered questions remain. For instance, can molecular subtypes of ACC be identified? If so, what is their underlying pathogenetic basis and do they possess clinical significance?<h4>Experimental design</h4>We did a whole genome gene expression study of a large cohort of adrenocortical tissues annotated with clinicopathologic data. Using Affymetrix Human Genome U133 Plus 2.0 oligonucleotide ...[more]

Beta-catenin status effects in human adrenocortical carcinomas (33), adenomas (22), and normal adrenal cortex (10)

Project description:We scored adrenocortical carcinomas and adenomas for abnormal beta-catenin staining, and sequenced the beta-catenin gene in some samples. We compared adrenocortincal carcinomas with and without abnormal beta-catenin staining and found many significant expression differences and significant results from enrichment testing. A similar comparison in the adenomas gave relatively few differences, and they did not correlate to differences found for the carcinomas. Abnormal beta-catenin staining was associated with mitotic rate and poorer patient survival in the carcinomas. In a second independent data set (given in a supplement) we again found beta-catenin associated with poor survival. The array data given is the same as GEO series GSE10927, with additional characteristics about beta-catenin, and new patient followup data. The analysis shown in a supplementary Excel file is also new. Human samples of 33 adrenocortical carcinomas, 22 adrenocortical adenomas, and 10 normal adrenal cortex samples, each from a different patient, had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. 23 of the carcinomas were used in survival analysis. 27 additional samples without array data were also used in a survival analysis.

shRNA knockdown of ZMIZ1 in human T-cell Acute Lymphoblastic Leukemia cell line CEM

Project description:Human T-cell Acute lymphoblastic Leukemia cell line CEM was transfected with either shRNA against ZMIZ1 or scrambled shRNA. Four (non-paired) biological replicates of each condition had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. A supplementary Excel workbook holding the same processed data as the series matrix file is provided, with some probe set annotation, and a simple statistical comparison. The raw (.CEL) files are also provided.

Transcription profiling of human A549 lung adenocarcinoma cell line time Course of TGF-beta treatment

Project description:Time Course of TGF-beta treatment of A549 lung adenocarcinoma cell line on Affymetrix HG_U133_plus_2 arrays; triplicate experiments. The goal of the experiment is to profile temporal gene expression changes during TGF-beta-induced epithelial-mesenchymal transition (EMT). During EMT cancer cells loose their epithelial specifc proteins and gain mesenchymal proteins to acquire migratory and invasive phenotype essential for metastasis. Human A549 lung adenocarcinoma cell line was treated with 5 ng/mL TGF-beta for 0, 0.5, 1, 2, 4, 8, 16, 24, and 72 h to induce EMT. The experiment was repeated 3 times. Samples were assayed using Affymetrix HG_U133_plus_2 arrays with 54675 probe-sets, using standard techniques. We provide the raw .CEL files and a supplementary Excel spreadsheet with log-transformed data and selected results from a statistical analysis. Experiment Overall Design: Human A549 lung adenocarcinoma cell line was treated with 5 ng/mL TGF-beta for 0, 0.5, 1, 2, 4, 8, 16, 24, and 72 h. The experiment was repeated 3 times. Samples were assayed using Affymetrix HG_U133_plus_2 arrays with 54675 probe-sets, using standard techniques. The 2 h sample of the third experiment was not run on an array due to poor RNA, so that only 26 arrays were run.

Sf1+ mouse adrenocortical cells vs. Wnt-responsive mouse adrenocortical cells

Project 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 37°C. 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 10μg/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.
