To confirm the detected changes in transcript levels between the H and L groups (n = 3), we quantified the expression level of 8 genes (identified via RNA-Seq) selected from the DEGs: peroxisome proliferator-activated receptor gamma, coactivator 1 beta (PPARGC1B), secreted phosphoprotein 2 (SPP2), stearoyl-CoA desaturase 5 (SCD5), myogenic differentiation (MyoD), chloride channel 4 (CLCN4), collagen, type I, alpha 1 (COL1A1), myogenin (MyoG), and stearoyl-CoA desaturase (SCD).
Three genes with relevant functions in lipid metabolism (SCD5, SCD, and PPARGC1B), 2 with a relevant functions in myogenesis (MYOD1 and MYOG), one related to fibrogenesis (COL1A1), one showing high expression levels in Y2 (CLCN4) and one showing high expression in Y1 (SPP2), were subjected to quantification by RT-PCR.
