Title |
GM02782_sham_C3 |
Sample type |
RNA |
|
|
Channel 1 |
Source name |
AT patient
|
Organism |
Homo sapiens |
Characteristics |
cell line: GM02782 cell type: lymphoblastoid genotype: ATM-/-
|
Biomaterial provider |
Coriell; http://ccr.coriell.org/Sections/Search/Search.aspx?PgId=165&q=GM02782
|
Growth protocol |
Cells were cultured in RPMI supplemented with 15% FBS (Life Technologies). All cell lines obtained from the NIGMS were maintained at 37oC in a humidified atmosphere of 5% CO2 and were routinely tested and shown to be free of mycoplasma contamination using a commercial assay
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was isolated using Qiagen RNeasy kit (Qiagen Sciences). The quality of all RNA samples was confirmed using an Agilent 2100 Bioanalyzer (Agilent Technologies, Palo Alto, CA).
|
Label |
Cy3
|
Label protocol |
1 μg of sample RNA and global reference RNA were converted to cDNA with reverse transcriptase and then amplified using T7 RNA polymerase while labeling with either cyanine 3 deoxyuridine triphosphate (Cy3-dUTP) or Cy5-dUTP. The quality of each labeled cRNA was evaluated using an Agilent 2100 bioanalyzer before hybridization; 750 ng of Cy3- and Cy5-labeled cRNA were used in the hybridization.

|
|
|
Hybridization protocol |
The labeled cRNA from human lymphoblastoid cells was hybridized with the labeled global reference cRNA on an Agilent array in a hybridization oven at 60°C for 17 hr.
|
Scan protocol |
Scanned on an Agilent Technologies Scanner G2505B US23502387 Images were quantified using Agilent Feature Extraction Software (version A.7.1.1).
|
Description |
cell lines with same ATM genotype receiving the same treatment (Sham or IR) are biological replicates of one-another
|
Data processing |
Each RNA sample was subjected to microarray analysis twice with C3/C5 dyes swap (C3 labeled test sample / C5 labeled reference, C5 labeled test sample /C3 labeled reference) in both Basal and IR study. The data from each array were normalized using EPIG method, which included array-based systematic variation normalization [Chou, J.W., Paules, R.S., and Bushel, P.R. (2005). Systematic variation normalization in microarray data to get gene expression comparison unbiased. J. Bioinform. Comput.Biol. 3, 225-241], profile-based C3/C5 dye-swap correction, and biological reference state alignment [Chou, J.W., Zhou, T., Kaufmann, W. K., Paules, R.S., and Bushel, P.R. (2007). Extracting gene expression patterns and identifying co-expressed genes from microarray data reveals biologically responsive processes. BMC Bioinformatics 8, 427. doi:10.1186/1471-2105-8-427].
