| Title |
ClockKO_ZT20_pool2 |
| Sample type |
RNA |
| |
|
| Source name |
whole kidney from clock KO mice, ZT20
|
| Organism |
Mus musculus |
| Characteristics |
tissue: left kidney
genotype/variation: clock(-/-)
zt time: 20
|
| Treatment protocol |
Animals were sacrificed for microdissection every 4 hours, i.e. at ZT0, ZT4, ZT8, ZT12, ZT16 and ZT20 (ZT – Zeitgeber (circadian) time, indicates time of light-on as ZT0 and time of light-off as ZT12).
|
| Growth protocol |
A colony of the clock deficient mice was established from breeding pairs of clock(+/-) heterozygous mice originally generated by Debruyne et al. (Neuron, 50: 465-477, 2006). All mice were adapted to a 12 hours light, 12 hours dark cycle (LD) for two weeks and then placed in constant darkness (DD) for 30 hours before sacrifice.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA from whole kidneys of wild-type or clock deficient mice was isolated with the standard method of Chomczynski and Sacchi (Anal Biochem, 162: 156-159, 1987). All RNA quantities were assessed by NanoDrop-ND-1000 spectrophotometer and the quality of RNA was controlled on Aligent 2100 bioanalyzer chips.
|
| Label |
biotin
|
| Label protocol |
RNA extracted from 2 or 3 mice were combined and 100 ng was used to perform target preparation using the Whole Transcript Sense Target Labeling Protocol procedure (Affymetrix, High Wycombe, UK).
|
| |
|
| Hybridization protocol |
Affymetrix Mouse Gene 1.0 ST arrays were hybridized with 5 microgramme of labeled, amplified cDNA , washed, stained and scanned according to the protocol described in Affymetrix GeneChip® Expression Analysis Manual (Fluidics protocol FS450_0007)
|
| Scan protocol |
Scanning was done on an Affymetrix GeneChip Scanner 7G
|
| Data processing |
Normalized expression signals were calculated from Affymetrix CEL files using RMA (Irizarry et al., 2003) for each tissues separately.
