Sample GSM67028 Query DataSets for GSM67028
Status Public on Aug 02, 2006
Title CtrXM_48hr.3_m
Sample type RNA
 
Channel 1
Source name Zebrafish liver tissue
Organism Danio rerio
Characteristics Zebrafish liver tissue exposed to arsenic
Growth protocol Zebrafish were reared at room temperature (27 ± 2°C)
Extracted molecule total RNA
Extraction protocol Total RNA of tissue samples were extracted using Trizol reagent (Invitrogen) according to the manufacturers instructions.
Label Cy5
Label protocol For fluorescence labeling of cDNAs, 20 µg of total RNA from the reference and experimental samples were
reverse transcribed in the presence of Cy3-dUTP and Cy5-dUTP (Amersham Inc.), respectively. Labeled cDNA were pooled, concentrated, and
resuspended in DIG EasyHyb (Roche Applied Science) buffer for hybridization.
 
Channel 2
Source name Zebrafish liver tissue
Organism Danio rerio
Characteristics Reference RNA was obtained by pooling equal amount of male and female total RNA extracted from liver tissues
of wild-type zebrafish.
Extracted molecule total RNA
Extraction protocol Total RNA of tissue samples were extracted using Trizol reagent (Invitrogen) according to the manufacturers instructions.
Label Cy3
Label protocol For fluorescence labeling of cDNAs, 20 µg of total RNA from the reference and experimental samples were reverse
transcribed in the presence of Cy3-dUTP and Cy5-dUTP (Amersham Inc.), respectively. Labeled cDNA were pooled, concentrated, and resuspended in
DIG EasyHyb (Roche Applied Science) buffer for hybridization.
 
 
Scan protocol The arrays were scanned using the GenePix 4000B microarray scanner (Axon Instruments, USA) and the generated images with their fluorescence signal intensities were analyzed using GenePix Pro 4.0 image analysis software (Axon Instruments, USA).
Description Fish were treated with arsenic [As(V)] acid (Na2HAsO4.7H2O; Sigma, USA) at 60 mg/L in a static condition for 96 hours (h) whereby less than 10% mortality occurred in arsenic-treated group within the experiment duration. No mortality was observed in the control group. The concentration was chosen based on an initial survival versus concentration experiment. Fish livers were sampled at 8 h, 24 h, 48 h and 96 h, and 12 fish livers were separated into 3 pooled-samples (each pooled samples consist of 4 livers) at each time point.
Three biological replicates are performed for each time point (8,24,48,96 hrs). Test and control samples are hybridized against a reference. No dye swap experiment has been performed.
Data processing The data were global median normalized.Normalized ratio of means defined by CH1/CH2
