C2C12 were transfected with 30 nM of Mef2a siRNA-2 or scrambled control and RNA was then isolated at 48 h DM, as described above, in duplicate. A total of 5 μg of purified RNA was delivered to McGill University and Genome Quebec Innovation Centre (MUGQIC) for cDNA library preparation (Illumina TruSeq mRNA sample preparation kit), RNA-sequencing (Illumina HiSeq 2000; 100 bp paired-end reads; 4 samples per lane) and bioinformatic analysis. The bioinformatic pipeline included Illumina CASAVA software, Trimmomatic (40 (link)), and TopHat/Bowtie (41 (link)). Sequencing reads were aligned to the mm10 genome assembly. HTSeq-count generated raw read counts which were used to identify differentially expressed genes using edgeR (42 (link)) and DESeq (43 (link)).
