Involvement of Taste Receptors in the Oro-Sensory Perception of Nutrients in Rainbow Trout (Oncorhynchus mykiss) Fed Diets with Different Fatty Acid Profiles

Figure 3

Gene expression profiling related to taste receptors in the tongues of rainbow trout (RT) fed for 30 days with commercial (C), V1 and V2 diets. Relative gene expression measured by RT-PCR of ffar2a, ffar2b/e, ffar2c/f, ffar2g, ffar3a, ffar3b, gnat2, gpr84, gpr119, cd36, tas1r1a, tas1r1b, tas1r2 tas1r3, casr and gpr92/93 in the tongue of RT fed for 30 days with Cl, V1 and V2 diets. Values are expressed as group mean ± SEM; fold change v. C diet for all genes. One-way ANOVA, Tukey post hoc; Different lower case letters indicate significant differences (P < 0.05) among diets (n = 6).
