Characterization, phylogeny, and responses of leptin to different nutritional states in critically endangered Yangtze sturgeon (Acipenser dabryanus)

Leptin is an important energy homeostasis hormone in mammals. However, the role of leptin in energy balance of fish remains controversial. In this study, we characterized Yangtze sturgeon (Acipenser dabryanus) leptin (Adleptin) with a full-length 507 bp coding sequence (CDS) encoding 168 amino acids (aa) and we used phylogenetic analysis to identify it as leptin A. The tissue expression profiles suggested that Adleptin is widely expressed in...
