| Title |
SI1_wk2_HF (high fat diet, high calcium) |
| Sample type |
RNA |
| |
|
| Source name |
SI1 after 2 wks on a HFD, HCa diet
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57Bl/6J
gender: male
tissue: small intestine, SI 1
dietary fat: high
dietary calcium: high
age: 9wks old at start of diet intervention
diet intervention time: 2wks
|
| Treatment protocol |
After a run-in period of 3 weeks on a low-fat diet, 9-week-old mice were fed a high-fat (HF) purified diet with a high calcium concentration of 150mmol/kg (HCa diet) for 8 weeks.
|
| Growth protocol |
Male C57BL/6J mice were purchased from Harlan (Horst, The Netherlands) and were housed in the light- and temperature-controlled animal facility of Wageningen University. They had free access to water and prior to the diet intervention they received standard laboratory chow.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated using TRIzol reagent (Invitrogen, Breda, The Netherlands) according to the manufacturer’s instructions. The isolated RNA was further column-purified using the SV total RNA isolation system (Promega, Leiden, The Netherlands). RNA concentration was measured on a NanoDrop ND-1000 UV-Vis spectrophotometer (Isogen, Maarssen, The Netherlands) and analyzed on a bioanalyzer (Agilent Technologies, Amsterdam, the Netherlands) with 6000 Nano Chips according to the manufacturer’s instructions. For each part of small intestine, total RNA was pooled per diet group and per time point (n=6).

| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 ug total RNA (described in the eukaryotic section in the GeneChip Expression Analysis Technical Manual Rev. 3 from Affymetrix).
|
| |
|
| Hybridization protocol |
Following fragmentation, 10 ug of cRNA were hybridized for 16 hr at 45C on Affymetrix GeneChip Mouse Genome 430 2.0 Arrays. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
|
| Scan protocol |
Arrays were scanned on an Affymetrix GeneChip Scanner 3000.
|
| Description |
Pooled total RNA sample of 6 mice.
|
| Data processing |
Data analysis was performed using Microarray Analysis Suite 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method. The mean target intensity of each array was set to 500.
