Sample GSM1139917 Query DataSets for GSM1139917
Status Public on Apr 25, 2014
Title Liver-Caloric Restriction- Wt-replcate 1
Sample type RNA
 
Source name Liver-Caloric Restriction- Wt
Organism Mus musculus
Characteristics strain: C57BL/6J
agender: male
age: 2-5 months old
agenotype: Wild Type (SIRT1+/+)
treatment: 40% Caloric restricted diet
Treatment protocol Mice were feed either a 40% caloric restricted (CR) diet or an ad libitum (AL) diet until they reached 13-16 months at which time they were sacrificed, and the livers were collected and flash frozen.
Growth protocol 2-5 month old C57BL/6J male mice were housed following 1 of 2 dietary protocols
Extracted molecule total RNA
Extraction protocol RNA was extracted using Trizol reagent (Invitrogen, Carlsbad, CA) following the manufacturer’s instructions and homogenized using a polytron. Quantity and quality of the RNA was assessed using the Agilent 2100 Bioanalyzer with RNA 6000 Nano Chips.
Label biotin
Label protocol Standard Illumina protocol using Illumina TotalPrep RNA Amplification Kit (Ambion; Austin, TX, cat # IL1791) In short, 0.5ug of total RNA was first converted into single-stranded cDNA with reverse transcriptase using an oligo-dT primer containing the T7 RNA polymerase promoter site and then copied to produce double-stranded cDNA molecules. The double stranded cDNA was cleaned and concentrated with the supplied columns and used in an overnight in-vitro transcription reaction where single-stranded RNA (cRNA) was generated and labeled by incorporation of biotin-16-UTP.
 
Hybridization protocol Standard Illumina protocol. In short, a total of 0.75ug of biotin-labeled cRNA was hybridized at 58 degrees C for 16 hours to Illumina's Sentrix MouseRef-8 v2 Expression BeadChips (Illumina, San Diego, CA). Each BeadChip has ~24,000 well-annotated RefSeq transcripts with approximately 30-fold redundancy. The arrays were washed, blocked and the biotin labeled cRNA was detected by staining with streptavidin-Cy3.
Scan protocol Arrays were scanned at a resolution of 0.8um using the Beadstation 500 X from Illumina.
Description Liver-Caloric Restriction- Wt
Data processing Data was extracted using the Illumina BeadStudio software(v3.4.0). Any spots at or below the background were filtered out using an Illumina detection p value of 0.02 and above. The natural log of all remaining scores were used to find the avg and std of each array and the z-score normalization was calculated and presented below. Z-score = (raw value - avg)/std. Complete data including detection scores will be included in the supplemental file.
