Quantitative real time PCR (RT-qPCR) Total RNA from tissues was isolated using Lipid Tissue and Fibrous Tissue RNeasy Mini Kits (Qiagen). RNA concentration was measured by Nanodrop1000 (Thermo Fisher Scientific, Wilmington, USA). RNA was treated with DNAse I (Invitrogen, Carlsbad CA, USA) to remove any contaminating genomic DNA. cDNA was prepared from 200- 600 ng of RNA using High Capacity cDNA archive kit (Applied Biosystems, Carlsbad CA, USA). Equivalent of 5 ng of RNA was used for Real Time PCR reactions using Fast Advanced master mix and Gene expression assay (IRS1, GLUT4, BCKDHA, BCKDHB, ACOX, CPT1b, PLIN1, PLIN2, PLIN5, FASN, SCD1, DGAT2, PPAR-γ; Applied Biosystems). All samples were run in duplicates. Gene expression of target genes was normalized to expression of RPS13 (glucuronidase, beta) and fold change of expression was calculated using delta delta Ct method.
