Title |
AtT-20 cells 6h -/+ CRH replicate 3 |
Sample type |
RNA |
|
|
Channel 1 |
Source name |
100 nM Crh AtT-20 cells 6h
|
Organism |
Mus musculus |
Characteristics |
mouse, pituitary, corticotroph AtT-20 cells
|
Treatment protocol |
Cells were treated 18h after FCS deprication in DMEM pure with 100 nM human/rat Crh for 6h.
|
Growth protocol |
AtT-20 cells were plated in 10 cm cell culture dishes (Nunc) in DMEM medium (Invitrogen) including 10% FCS (Invitrogen) and antibiotics (Invitrogen) 48h before Crh treatment. With a confluency of approximately 50% cells were FCS-deprived 18h before Crh treatment.
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA of harvested AtT-20 cells was extracted using the TRIzol reagent (Invitrogen) according to manufacturer´s instruction. RNA qualitiy was analysed by gel electrophoresis.
|
Label |
Cy3
|
Label protocol |
aRNA synthesis and aRNA labelling was performed with the Amino Allyl MessageAmp™ aRNA Kit (Ambion) following the manufacturer’s protocol using 3 µg of total RNA.
|
|
|
Channel 2 |
Source name |
untreated AtT-20 cells 6h
|
Organism |
Mus musculus |
Characteristics |
mouse, pituitary, corticotroph AtT-20 cells
|
Treatment protocol |
Medium of all FCS-deprived cells was changed to DMEM pure without FCS and antibiotics. Crh treatment was performed by adding human/rat Crh (Bachem) to the medium with an end concentration of 100 nM. At indicated time points treated and control cells were harvested with TRIzol (Invitrogen).
|
Growth protocol |

|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA of harvested AtT-20 cells was extracted using the TRIzol reagent (Invitrogen) according to manufacturer´s instruction. RNA qualitiy was analysed by gel electrophoresis.
|
Label |
Cy5
|
Label protocol |
aRNA synthesis and aRNA labelling was performed with the Amino Allyl MessageAmp™ aRNA Kit (Ambion) following the manufacturer’s protocol using 3 µg of total RNA.
|
|
|
|
Hybridization protocol |
The labeled aRNA samples were hybridized on Max-Planck Institute 24 k mouse cDNA arrays (Max-Planck-Institute of Psychiatry, Munich, Germany) as described at Deussing JM et al. J Cereb Blood Flow Metab. (2007), performing 3 technical replicates for each control/CRH treated dye coupling combination.
|
Scan protocol |
Mircorarrays were scanned on a PerkinElmer Life Sciences ScanArray 4000 laser scanner.
|
Description |
6h_3
|
Data processing |
The microarray data analysis was accomplished by the fixed circle quantification method using QuantArray (PerkinElmer Life Sciences) and raw data was normalized using a nonlinear regression method (Yang YH et al., Nucleic Acids Res (2002)).
