Sample GSM471594 Query DataSets for GSM471594
Status Public on Feb 28, 2014
Title wk12_DEN50__DEN_14
Sample type RNA
Source name rat liver, cirrhosis (DEN 50mg, week 12)
Organism Rattus norvegicus
Characteristics strain: Wistar
sex: male
tissue: liver
disease status: cirrhosis
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, 100mg/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. In a separate study, the erlotinib dose was lowered to 0.5 mg/kg. The vehicle groups from the two studies were not significantly different so they were combined together for analysis. Rats were weighed at the end of each week. 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.
Extracted molecule total RNA
Extraction protocol Using frozen non-tumor liver tissues, total RNA was extracted using TRIzol (Invitrogen).
Label Cy5
Label protocol Refer to the Illumina beadarray Assay System Manual
Hybridization protocol Refer to the Illumina beadarray Assay System Manual
Scan protocol Refer to the Illumina beadarray Assay System Manual
Description wk12_DEN50__DEN_14
Data processing For each probe, replicate mesurements were averaged after removing outliers. Data were were then normalized using the cubic spline algorithm using GenePattern IlluminaNormalizer module.
