| Title |
D0 Mouse 1_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.

Cy3
|
| 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 1
|
| 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.
