The VEGF signaling pathway in the BAT of the different groups of mice and verification. a VEGF signaling pathway and KEGG analysis of this pathway and related genes. Red represents the upregulated genes. Solid arrows indicate a direct action, dashed arrows indicate indirect action; “ − P” represents dephosphorylation. b Levels of the VEGF and COX2 proteins. *P < 0.05 and **P < 0.01 represent statistical significance. n = 3
