Moreover, several genes involved in the AMPK signaling pathway and insulin resistance such as CPT1A, PPARG coactivator 1 alpha (PPARGC1A), glucose-6-phosphatase catalytic subunit (G6PC), and glycogen synthase 2 (GYS2) were upregulated, while SREBP1, Acetyl-CoA carboxylase alpha (ACACA), insulin receptor substrate 1 (IRS1), SCD, HMGCR and FASN in AMPK signaling pathway were downregulated in the under-stress birds compared with the control group. Here, G6PC1 is linked to Insulin resistance.
