Full-length cDNA sequences of five JAKs and seven STAT members were obtained from yellow catfish.
All of these members were widely expressed across the eleven tissues but at the variable levels.
Leptin changed TG content and mRNA expression of several JAKs and STATs members, and genes involved in lipid metabolism.
JAK2a/b–STAT3 pathway exerts main actions in leptin influencing lipid metabolism.
