tissue: heart phenotype: cardiac hypertrophy and fatty heart diet: HFHS diet for 23 months
Treatment protocol
The pigs were fasted for 12 hours and euthanized with ketamine and xylazine. Pig hearts were sampled and preserved in liquid nitrogen.
Growth protocol
The control group consisted of 6 Bama pigs fed a control diet, and the HFHSD group comprised 6 pigs that were induced with a HFHS diet, which included 37% sucrose, 53% control diet and 10% pork lard for 23 months.
Extracted molecule
total RNA
Extraction protocol
Trizol extraction of total RNA was performed according to the manufacturer's instructions.
Label
biotin
Label protocol
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 6 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
Hybridization protocol
Following fragmentation, 10 ug of cRNA were hybridized for 16 hr at 45C on GeneChip Drosophila Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol
GeneChips were scanned using the GeneChip Scanner 3000.
Description
Gene expression data from HFHSD group Bama minipig_144
Data processing
Slides were scanned by GeneChip Scanner 3000 (Affymetrix, Santa Clara, CA, US) and Command Console Software 3.1 (Affymetrix, Santa Clara, CA, US) with default settings. Raw data were normalized by MAS 5.0 algorithm, Gene Spring Software 11.0 (Agilent technologies, Santa Clara, CA, US).
