| Title |
Cyp1a1_1b1_12_1 |
| Sample type |
RNA |
| |
|
| Source name |
Cyp1a1_1b1 DKO mouse at week 12
|
| Organism |
Mus musculus |
| Characteristics |
strain/background: B6
genotype: Cyp1a1 Cyp1b1 double-knockout
gender: male
tissue: preputial gland duct
treatment: oral benzo[a]pyrene (BaP)
treatment duration: 12 weeks
|
| Treatment protocol |
Male mice of the three genotypes (75 mice total per genotype) were begun on the benzo[a]pyrene (BaP) diet at 6 weeks of age. BaP was added with the corn oil-soaked food such that the mice ingested approximately 12.5 mg/kg/day. Groups of N=15 for each genotype were killed at zero, 4, 8, 12 and 16 weeks, and preputial glands were dissected free of surrounding tissue.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Snap-frozen preputial glands (N=2 mice per group) from WT, Cyp1a1KO and Cyp1a1/1b1 DKO males treated with BaP at 0, 4, 8, 12, and 16 weeks were allowed to thaw overnight at -20oC with RNAlater®-ICE reagent prior to homogenization using Tri-Reagent. RNA isolation was performed using Qiagen RNeasy mini-kits.
