“…The results of transcriptomic analysis showed that DEGs in tissues were mainly concentrated in lipid metabolism among the functional categories related to metabolism, which are mainly concentrated in the PPAR signaling pathway. The PPAR pathway mainly regulates the expression of genes related to lipid metabolism that includes fatty acid synthesis, oxidation, transport and deposition, and resultantly improves the quality of livestock and poultry meat ( Zhao et al, 2022 ; Zhang et al, 2023 ). PPARγ , a key regulator of fat formation in chickens, can regulate cholesterol metabolism, stimulate the expression of genes related to lipid metabolism and adipocyte differentiation ( Liu et al, 2010 ; Wang et al, 2017 ).…”
