Sample GSM1242863 Query DataSets for GSM1242863
Status Public on Oct 01, 2015
Title D0 Mouse 3_lung [IP]
Sample type RNA
 
Channel 1
Source name D0_lung
Organism Mus musculus
Characteristics strain: MutaTMMouse
gender: male
age: ~13 weeks
exposed to: D0; vehicle control
tissue: lung
tissue collection tiime: 72 hrs following the final dose
Treatment protocol Mice were dosed via oral gavage daily for 28 consecutive days. Three different doses of indeno(123,cd)pyrene dissolved in olive oil were selected to dose the animals: 12.5 mg/kw-bw/day, 25 mg/kg-bw/day, and 50 mg/kg-bw/day. Control animals were gavaged with olive oil only. Tissues were collected 72 hours following the final dose.
Growth protocol Male MutaTMMouse, aged ~13 weeks, were individually housed in a plastic film isolator, provided with water and food (2012 Teklad Global standard rodent diet) ad libitum, and were subjected to a 12 hour light/dark cycle. All animal procedures were in accordance with the guidelines of the Canadian Council for Animal Care and approved by the Health Canada Animal Care Committee.
Extracted molecule total RNA
Extraction protocol Mice were anaesthetized under isofluorane followed by exsanguination. Murine lung, liver, and forestomachs were removed, placed in cryovials and immediately snap frozen in liquid nitrogen. Tissues were stored at -80oC until RNA extraction was performed. Total RNA was extracted from random sections (D0 n=4, D1 n=5, D2 n=5, D3 n=5) using Trizol reagent (Invitrogen) and further purified using the RNeasy Mini Kit (Qiagen) with an on-column DNase I digestion according to the manufacturer's instructions. Total RNA concentration and quality was determined using a Nanodrop 1000 Spectrophotometer and an Agilent 2100 Bioanalyzer, respectively. RNA samples used for gene expression microarray had A260/280 ratios > 2.0 and RINs > 7.1.
Label Cy5
Label protocol Total RNA (200ng per array) was labeled using the Agilent Quick Amp Labeling Kit, Two-Color (Agilent Cat #: 5190-0444), according to the manufacturer's instructions. Control and experimental samples were labeled with Cyanine 5-CTP; whereas universal mouse reference RNA was labeled with Cyanine 3-CTP.
 
Channel 2
Source name Universal Mouse Reference RNA
Organism Mus musculus
Characteristics sample source: 11 mouse cell lines
vendor: Stratagene, La Jolla, CA, USA
catalog #: 740100

Label protocol Total RNA (200ng per array) was labeled using the Agilent Quick Amp Labeling Kit, Two-Color (Agilent Cat #: 5190-0444), according to the manufacturer's instructions. Control and experimental samples were labeled with Cyanine 5-CTP; whereas universal mouse reference RNA was labeled with Cyanine 3-CTP.
 
 
Hybridization protocol Equal amounts of Cy5-labeled experimental cRNA and Cy3-labeled reference RNA (300ng) were co-hybridized to Agilent Sureprint G3 Mouse GE 8x60K microarray slides, according to the instructions outlined in the Agilent Two-Color Microarray-Based Gene Expression Analysis (Quick Amp Labeling) Protocol. Samples were hybridized for 17 hours at 65oC and 10 rpm.
Scan protocol Microarray slides were scanned using an Agilent DNA Microarray Scanner (G2505B) according to manufacturer's recommendations. Data was extracted from the scanned images using Feature Extraction Version 10.7.3.1.
Description Sample 9
Data processing The log2 of the ratio (sample(Cy5)/reference(Cy3)), using the median signal intensities were normalized using lowess using the transform.madata function in the maanova library in R.
