γ-Aminobutyric acid effectively modulates relative gene mRNA expressions of GH, IGF-Ⅰ, HSP70, and HSP90 of largemouth bass (M. salmoides) under combined stress of flow velocity and density (the mRNA expression of the liver of largemouth bass under fed with different treatments for 60 days. Values are means ± SD of three replicate groups, with 30 fish in each group; different letters in the same color indicate significant differences in numerical values (r < 0.05), as shown in the figure). GABA, γ-aminobutyric acid; GH, growth hormone; HSP70, heat stress protein 70; HSP90, heat stress protein 90IGF-1, insulin-like growth factor-1.
