(-)-Epigallocatechin-3-O-Gallate Regulates Muscle Growth, Antioxidant Status, and Nutritional Composition of Juvenile Common Carp (Cyprinus carpio L.)

Figure 3

Effects of dietary EGCG on myofiber growth and the texture of raw fillet in common carp (C. carpio L.). (a) Transversal section of a dorsal white muscle fiber; (b) myofiber density and diameter (n = 3); (c) diameter distribution of the muscle myofiber (n = 3). Data are represented as mean; (d) muscle growth-related gene expressions (n = 9); (e) muscle fluorescence intensity (n = 6); (f) texture of raw fillet (n = 9). The data are represented as the mean ± SEM. One-way ANOVA followed by Duncan’s test was used to analyze the discrepancy among all test groups. Different symbols denote significant differences (). P-values indicate a significantly linear or quadratic dose–response relationship. Liner trend and quadratic trend were analyzed by polynomial contrasts (A, ANOVA; L, linear; Q, quadratic). Different column or line colors represent dietary EGCG supplemented at 0, 0.05, 0.25, 0.5, or 1 g/kg.
