Sample GSM251858 Query DataSets for GSM251858
Status Public on Dec 01, 2008
Title Human Prostate GSK-6
Sample type RNA
 
Channel 1
Source name Reference
Organism Homo sapiens
Characteristics Reference
Extracted molecule total RNA
Extraction protocol Prostate samples embedded in OCT were used for laser capture microdissection (LCM). Approximately 2000-3000 epithelial cells per sample were collected from 8µm sections using the Arcturus Veritas™ Laser Capture Microdissection System according to the Arcturus HistoGene LCM Frozen Section Staining Kit Protocol (Mountain View, CA). Total RNA was isolated using the Arcturus Picopure™ Kit, and the samples were treated with DNAse using the Qiagen RNase-Free DNase Set (Qiagen Inc, Valencia, CA). Total RNA was subjected to two rounds of linear amplification using the Ambion MessageAmpII Kit (Ambion Inc, Austin, TX), quantitated in a Gene-Spec III spectrophotometer (Hitachi, Tokyo) and aRNA integrity evaluated using gel electrophoresis.
Label Cy5
Label protocol Complementary DNA (cDNA) probe pairs were prepared by amino-allyl reverse transcription using 2 µg of amplified RNA from microdissected samples and 30 µg of total RNA from a reference RNA pool composed of total RNA isolated from the LNCaP, DU145, and PC3 prostate cell lines. Probes were labeled with either Cy5 or Cy3 fluors (Amersham Bioscience, Piscataway, NJ) and competitively hybridized to custom cDNA microarrays spotted in duplicate with approximately 6,700 unique cDNA clones from the Prostate Expression Database (PEDB) as previously described in Pritchard CC, Hsu L, Delrow J, and Nelson PS. Project normal: defining normal variance in mouse gene expression. Proc Natl Acad Sci U S A 2001;98:13266-13271.

Scan protocol Fluorescence array images were collected using a GenePix 4000B fluorescent scanner (Axon Instruments, Foster City, CA) and processed as we have previously described in True L, Coleman I, Hawley S, et al. A molecular correlate to the Gleason grading system for prostate adenocarcinoma. Proc Natl Acad Sci U S A 2006;103:10991-10996.
Description Human Prostate GSK-6 from Human hybridized against Reference
Data processing Changes in gene expression were evaluated using the Statistical Analysis of Microarray (SAM) program (http://www-stat.stanford.edu/_tibs/SAM/) to perform a one-sample t-test assessing the effect of Acyline treatment on gene expression (22). An FDR (false discovery rate) of less than 5% was considered significant. Quantile normalization was performed in Bioconductor (23) to allow single channel comparison of the absolute signal intensities in the experimental channel across different arrays in the same experiment.
