An Illumina RNA amplification kit (Ambion, Austin, TX, USA) was used according to the manufacturer’s instructions to obtain biotinlabeled cRNA from 500 ng of total RNA.
Hybridizations to Illumina HumanWG-6 v3.0 Expression BeadChips (Illumina Inc., San Diego, CA, USA) containing probes for PLIN2 and PLIN5, were performed by the Finnish DNA Microarray Center at Turku Center for Biotechnology according to the Illumina BeadStation 500x manual.
Hybridized probes were detected with Cyanin-3-streptavidin ( , Amersham Biosciences, GE Healthcare, Uppsala, Sweden) using Illumina BeadArray Reader (Illumina Inc.) and BeadStudio v3 software (Illumina Inc.).
The gene expression data and the raw data sets for skeletal muscle have been deposited in the GEO database (
