| Title |
Hepa1-6, Oleic acid treatment |
| Sample type |
RNA |
| |
|
| Source name |
Hepa1-6 cells
|
| Organism |
Mus musculus |
| Characteristics |
treatment: Oleic acid (500 µM)
|
| Treatment protocol |
Hepa1-6 cells were seeded and incubated overnight, followed by treatment with 500 µM concentration of fatty acids for 24 hrs. All fatty acid stocks were initially reconstituted in absolute ethanol. Sub-stocks of fatty acids at 25 mM were prepared in filter-sterilised KOH at 70 mM. Complete DMEM supplemented with fatty acid-free bovine serum albumin (BSA; Sigma-Aldrich, St. Louis, MO) were filter sterilised, and incubated for 30 min with fatty acids to complex BSA to fatty acids. Ratio of BSA to fatty acids were approximately 1:2. Vehicle control treatments only contained equivalent mixture of ethanol and KOH.
|
| Growth protocol |
Hepa1-6 cells (# CRL-1830) were obtained from American Type Culture Collection (ATCC; Manassas, VA) and cultured in Dulbecco's modified Eagle medium (DMEM) supplemented with 10% fetal bovine serum, 100 U/mL penicillin and 1000 µg/mL streptomycin (Lonza, Verviers, Belgium) in a humidified chamber at 37oC with 5% CO2.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from samples using the RNeasy kit (Qiagen) with a DNase digestion step according to the manufacturer’s protocol. RNA quality was verified on an Agilent 2100 Bioanalyzer (Agilent Technologies, Amsterdam, The Netherlands) using 6000 Nano Chips according to manufacturer’s instructions. RNA was considered suitable for array hybridization only if RNA integrity number exceeded 8.0. RNA from 6 samples per group was pooled for microarray analysis
|
| Label |
biotin
|
| Label protocol |
Total RNA (100ng per sample) was labeled with the Whole-Transcript Sense Target Assay (Affymetrix, Santa Clara, CA, USA; P/N 900652).
|
| |
|
| Hybridization protocol |
Hybridization and washing of the Affymetrix GeneChip Mouse Gene 2.1 ST peg arrays were performed on a GeneTitan Instrument according to the manufacturer's recommendations (Affymetrix, Santa Clara, CA, USA).
|
| Scan protocol |
Arrays were scanned on an Affymetrix GeneTitan instrument (Affymetrix, Santa Clara, CA, USA).
|
| Data processing |
Expression estimates were calculated applying the RMA algorithm in the Bioconductor library 'Oligo' (v1.46.0).
