SCD1 and fat acid metabolism genes expression in goat. (A) Schematic diagram of SCD1 role in lipid synthesis. CE, cholesteryl esters; TG, triglycerides; WE, wax esters; PL, phospholipids; DG, diacylglycerol. (B) Effects of SCD1 on lipid accumulation and expression of genes related to lipid metabolism. (C) Variation of genes in lipid metabolism in mammary gland and muscular tissue at different developmental stages including de novo fat acid synthesis (FASN, ACACA, and PPARG), triacylglycerol synthesis (DGAT1, DGAT2, GPAM, AGPAT6, and LPIN1), triacylglycerol degradation (PNPLA2 and LIPE), fat acid uptake and intracellular transport (FABP3 and CD36), and fat acid oxidation (PPARA, ACOX1, and CPT1B) by RNA-seq.
