Sample GSM81970 Query DataSets for GSM81970
Status Public on Jul 14, 2006
Title CaCo2-SF-FAC_a
Sample type RNA
 
Channel 1
Source name caco-2 cells
Organism Homo sapiens
Characteristics Caco-2 cells, originating from a human colorectal carcinoma (HTB-37)
Biomaterial provider American Type Culture Collection (Manassas, VA)
Treatment protocol Fully differentiated CaCo-2 cells were submitted to Iron and serum free medium + 4.4 µM FAC (ferric ammonium citrate) (SF-FAC)
Growth protocol CaCo-2 cells were grown in DMEM containing 10% FBS, 1X non-essential amino-acids, 2mM L-glutamine and 100 IU/ml antibiotics (penicillin and streptomycin) (all reagents were purchased from Gibco BRL) in a humidified atmosphere of 95% air and 5% CO2.
Extracted molecule total RNA
Extraction protocol TRI REAGENT kit (Sigma)
Label cy5
Label protocol Agilent Low RNA Input Fluorescent Linear Amplification Kit (p/n 5184-3523)
 
Channel 2
Source name pool of all used RNA
Organism Homo sapiens
Characteristics Caco-2 cells, originating from a human colorectal carcinoma (HTB-37)
Biomaterial provider American Type Culture Collection (Manassas, VA)
Treatment protocol Pool of all extracted RNAs from fully differentiated CaCo-2 cells submitted to various treatments:
(1) DMEM 10% FBS (DMEM-FBS)
(2) DMEM 10% FBS and 100 µM Hemin (DMEM-Hemin)
(3) Iron and serum free medium (IMDM+serum complement) (SF-0)
(4) Iron and serum free medium + 4.4 µM FAC (ferric ammonium citrate) (SF-FAC)
Growth protocol CaCo-2 cells were grown in DMEM containing 10% FBS, 1X non-essential amino-acids, 2mM L-glutamine and 100 IU/ml antibiotics (penicillin and streptomycin) (all reagents were purchased from Gibco BRL) in a humidified atmosphere of 95% air and 5% CO2.
Extracted molecule total RNA
Extraction protocol TRI REAGENT kit (Sigma)
Label cy3
Label protocol Agilent Low RNA Input Fluorescent Linear Amplification Kit (p/n 5184-3523)
 
 
Hybridization protocol Agilent oligonucleotide microarray in situ Hybridization Plus kit (p/n 5184-3568).
Scan protocol Agilent dual laser DNA microarray scanner (p/n G2566AA) and Feature Extraction software 7.5 (p/n G2567AA)
Description Each sample were labelled with cy5 and a pool of each sample was constituted and labelled with cy3
Data processing adjustment local background subtraction and global background Normalization method : Linear&Lowess method. only features with a Signal-to-Noise Ratio (SNR) in at least one channel ≥ 2.6 were used for further analysis and saturated features (50% of pixels > saturation threshold, 65502) or non uniform features were discarded.
