| Title |
T1_HypM |
| Sample type |
RNA |
| |
|
| Source name |
maternal exposure to dioxin, HypM
|
| Organism |
Rattus norvegicus |
| Characteristics |
strain: Wistar
agent (mother exposed to): TCDD
gender (pup): male
age (pup): PND70
tissue (pup): hypothalamus
|
| Treatment protocol |
Pregnant Wistar rats were orally treated with TCDD (1 mg/kg in corn oil) at GD15.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
The total RNA was extracted from the pituitary and hypothalamus of PND70 male pups according to the manufacturer's protocol (RNeasy Mini Kits).
|
| Label |
biotin
|
| Label protocol |
The total RNA (250 ng) was converted to its biotinylated-cRNA according to the manufacturer’s procedures (Illumina TotalPrep RNA Amplification Kit). Briefly, reverse transcription to synthesize the first-strand cDNA was performed for 2 hours at 42°C, using an oligo (dT) primer bearing a T7 promoter and reverse transcriptase (ArrayScript; Ambion). The second strand cDNA was synthesized by incubating the first strand for 2 hours at 16°C in the presence of DNA polymerase I and ribonuclease H. After cDNA purification by a short column, the eluted cDNA was used for in vitro transcription with T7 RNA polymerase. In vitro transcription was performed at 37°C for 14 hours, yielding the multiple copies of the biotinylated antisense RNA originated from respective mRNAs in the sample.

|
| Hybridization protocol |
The biotinylated-cRNA (total amount, 1,500 ng) prepared from each sample was overlaid onto an individual array spot of the rat microarray chip (RatRef12-v1 BeadChip; Illumina), according to the hybridization protocol. The chip was hybridized at 58°C for 19 hours.

| Scan protocol |
Standard Illumina scanning protocol

| Description |
SAMPLE 10
replicate 1
|
| Data processing |
The data were normalized by quantile normalization using lumi and preprocess package in R. This series includes two dataset; hypothalamic and pituitary samples (each case; N=3x2). The normalization applied each dataset.
