Organism Mus musculus
Characteristics testis
Strain: C57BL/6
Gender: male
Age: 24 months
Development stage: adult
Genetic modification: the animal was Ad Libitum
Individual Identifier: AMC119
Biomaterial provider Kevin Becker
Treatment protocol RNA was prepared from entire testis. The tissue was processed using a Bead Beater (Bio-Spec, Bartlesville, OK) follewed by RNA purification using the RNEasy Mini Kit (Qiagen, Valencia, CA)
Growth protocol The UMRR is provided in a solution of 70% ethanol and 0.1 M sodium acetate. Prepare the UMRR for use as follows: 1.Centrifuge the tube at 12,000 x g for 15 minutes at 4C. 2.Carefully remove the supernatant. 3.Wash the pellet in 70% ethanol. 4.Centrifuge the tube at 12,000 x g for 15 minutes at 4C. 5.Carefully remove the supernatant and air-dry the pellet at room temperature for 30 minutes to remove retained ethanol. 6.Resuspend the pellet in RNase-free water to the desired concentration.
Extracted molecule total RNA
Extraction protocol RNEasy protocol
Label Cy3
Label protocol Total RNA was labeled using Agilents Fluorescent Linear Amplification kit, according to manufacturers instructions (Product Number G2554A or P/N G2556-66002, Version 3.0, June 2002).
 
Channel 2
Source name Universal Mouse Reference Cell Line Pool
Organism Mus musculus
Characteristics Universale Mouse Reference
Biomaterial provider Stratagene
Growth protocol The UMRR is provided in a solution of 70% ethanol and 0.1 M sodium acetate. Prepare the UMRR for use as follows: 1.Centrifuge the tube at 12,000 x g for 15 minutes at 4C. 2.Carefully remove the supernatant. 3.Wash the pellet in 70% ethanol. 4.Centrifuge the tube at 12,000 x g for 15 minutes at 4C. 5.Carefully remove the supernatant and air-dry the pellet at room temperature for 30 minutes to remove retained ethanol. 6.Resuspend the pellet in RNase-free water to the desired concentration.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from cultured cells using a Stratagene Absolutely RNA kit. DNase-treated total RNA samples from 11 cultured cell lines derived from embryo, embryo fibroblast, kidney, liver/hepatocyte, lung/alveolar macrophage, B-lymphocyte, T-lymphocyte (thymus), mammary gland, muscle myoblast, skin, and testis were pooled in equal parts
Label Cy5
Label protocol Total RNA was labeled using Agilents Fluorescent Linear Amplification kit, according to manufacturers instructions (Product Number G2554A or P/N G2556-66002, Version 3.0, June 2002).
 
 
Hybridization protocol Agilent 60-mer oligo microarray processing protocol (SSC Wash/SureHyb Chamber set-up) V4.1, April 2004. Agilent Publication Number: G4140-90030 V4.1 APRIL 2004.
Scan protocol Slides were scanned with an Agilent DNA Microarray Scanner model G2505-64120 at 100% PMT in both channels, with a scan resolution of 10um. A scan window of 61 x 21.6 mm was used, then images were cropped to size and saved in a modified two-color TIFF format. Images were examined visually for evidence of foreign debris or major failures.

GSE7502 Effects of Aging and Calorie Restriction on the Global Gene Expression Profiles of Mouse Testis and Ovary

ID_REF Feature Number (FeatureNum).Please check the platform file for the annotation.
VALUE The experiment was done on two array platforms: NIA Mouse 44K Microarray v2.1 (GPL2552) (8 arrays, batch M1) and NIA Mouse 44K Microarray v2.2 (GPL4358) (20 arrays. batch M2). We used batch normalization for 2 groups of arrays since these arrays differed in the set of oligos and in the location of spots. Batch normalization is valid because in the 2nd set we used replications for mice of the same age and diet. ages from 6 to 24 months, diets ad libitum (AL) and calorie restriction (CR). First we normalized each set of arrays based on UMR signal (Cy5) as follows: (1) Take values from the columns gDyeNormSignal,rDyeNormSignal in the raw files and log-transform them using: log10(max(x,1)). These values will be referenced below as Xgi and Xri where i is array number. (2) Take average of Xri for the oligo among all arrays within the same platforms: AverXr = average(Xri). (3) For each array estimate Yi = Xgi-Xri+AverXr (4) Round Yi to 4 decimal digits. This is standard protocols when one platform of arrays used in the experimenti, which can be found at http://lgsun.grc.nia.nih.gov/ANOVA/help.html#arrayjoin . Then we estimated the median logintensity for each gene in all arrays for ovaries of mice from 6 to 24 months old on AL and CR diets (6 arrays) in the 1st batch (M1), and in arrays for the corresponding samples (2nd replication) in the 2nd batch (M2). The difference (M1-M2) was used as an adjustment factor which was added to the logintensity of that particular gene in the second batch. The data listed contains non-redundant genes which differ either in gene symbol or in the U-cluster (NIA Mouse Gene Index, ver. mm7 http://lgsun.grc.nia.nih.gov/geneindex/mm7/). The logintensities of those genes that are missing in one platform is set as -9999. Please see the supplementary raw data files for the complete set of spots for the arrays.
