| Title |
Tumor_18w_vechicle_DEN_123 |
| Sample type |
RNA |
| |
|
| Source name |
rat, hepatocellular carcinoma (DEN 50mg), treated with vehicle (week 18)
|
| Organism |
Rattus norvegicus |
| Characteristics |
tissue: hepatocellular carcinoma tumor
treatment: vehicle
strain: Wistar
|
| Treatment protocol |
Animals received humane care according to the criteria outlined in the “Guide for the Care and Use of Laboratory Animals” of the National Academy of Sciences. All animals were maintained in accordance with the institutional guidelines of the Massachusetts General Hospital Subcommittee on Research Animal Care. Male Wistar rats received weekly IP injections of diethylnitrosamine (DEN) at 50 mg/kg or vehicle control (PBS) for 18 weeks. A subset of rats received either daily (5X a week) IP injections of 2 mg/kg erlotinib or vehicle control during weeks 13 - 18. Animals were sacrificed at 9, 13 and 19 weeks after a one-week washout period to eliminate acute effects of DEN. At the time of sacrifice, the non-tumor liver tissues were collected in RNase-free tubes and snap-frozen in liquid nitrogen. Frozen tissues were stored at -80°C until RNA extraction.
