Sample type |
RNA |
|
|
Source name |
HBs_wild type IDH1_collagen-coated plates
|
Organism |
Mus musculus |
Characteristics |
cell type: hepatoblasts (HBs) from E14 WT mouse genotype/variation: expressing wild type IDH1 culture plate: collagen-coated plate
|
Treatment protocol |
For IDH1 experiments, culture media was supplemented with 25 ng/mL of doxycycline (d9891, Sigma-Aldrich). For hepatocyte differentiation assays, 5e6 HB cells were cultured on uncoated 10 cm tissue culture dishes in HB cell medium for up to 5 days and isolated for gene expression analysis.
|
Growth protocol |
HB cells were prepared from WT mice at embryonic day 14 and immortalized by plating at clonal density. HBs were maintained in HB media [DMEM/F-12 (Gibco Life Technologies, Grand Island NY) containing 10% fetal bovine serum, 1% penicillin-streptomycin, 50ng/mL epidermal growth factor, 30 ng/mL insulin-like growth factor II (PeproTech, Rocky Hill, NJ), 10 μg/mL insulin (Roche, Mannheim, Germany)] on plates coated with rat tail collagen (BD Biosciences, Bedford, MA) in a humidified atmosphere with 5% CO2 at 37°C.

Extracted molecule |
total RNA |
Extraction protocol |
Total RNA (1ug) was isolated using RNeasy Mini Kit (QIAGEN, Valencia, CA) and quality control performed using Bioanalyzer 2100 (Agilent Technologies).
|
Label |
biotin
|
Label protocol |
First strand cDNA synthesis was generated using a T7-linked oligo-dT primer, followed by second strand synthesis. An in vitro transcription reaction was performed to generate cRNA containing biotinylated UTP and CTP, which was subsequently chemically fragmented at 95°C for 35 minutes.
|
|
|
Hybridization protocol |
The fragmented cRNA is added to a hybridization solution containing several biotinylated control oligonucleotides (for quality control), and hybridized to Affymetrix 430Av2 microarray chips overnight at 45°C. The hybridization solution is then removed. The chips are transferred to a fluidics instrument that performs washes to remove cRNA that has not hybridized to its complementary oligonucleotide probe.
|
Scan protocol |
Scans were performed on Affymetrix confocal laser scanners.
