Dietary BBR suppressed the HCD-induced apoptosis in the intestine of largemouth bass. (A) TUNEL (green) staining images of intestinal sections (arrows indicate TUNEL signal, bar = 50 μm). (B) Apoptosis rate in intestinal sections. (C) Expression level of proapoptotic genes. (D) Intestinal Caspase 3 and Caspase 9 level. (E) Transmission electron microscope images of intestinal mitochondria (arrows indicate mitochondria, bar = 1 μm). (F) Expression level of anti-apoptotic genes. Data are represented as means ± SEM (n = 6). *, **, ***, ****Different from each other: *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, NS means no significant difference (One-way ANOVA, Duncan’s post hoc test).
