Abstract
Quercetin, a potential fish food supplement, has been reported to process many beneficial properties. However, some negative effects of quercetin have been observed, which pointed out necessity for additional studies to evaluate its safety. Therefore, the present study investigated effects of quercetin (0.01, 0.1, 1, 10, 100 and 1000 μg/L) on shoaling and anxiety behaviors through novel tank tests in zebrafish (Danio rerio). Furthermore, oxidative stress, neuroinflammation and apoptosis in the brains were examined to learn more about mechanisms of action related to quercetin. The results showed that quercetin at the lower concentrations exerted beneficial effects on shoaling and anxiety behaviors. On the contrary, when quercetin was up to 1000 μg/L, it exerted detrimental effects shown as decreases of movement and increases of anxiety behaviors. Generally, U-shaped responses of antioxidant enzyme activities (superoxide dismutase and catalase), and inversed U-shaped responses of inflammatory mediators (cyclooxygenase-2) and cytokines (interleukin-1β, interleukin-6, interleukin-10, and tumor necrosis factor α) to quercetin treatment were found in the brains. In addition, quercetin at the lower concentrations attenuated cell apoptosis, while even more apoptosis was found at the 1000 μg/L quercetin group. In conclusion, quercetin could exert beneficial or detrimental effects on the shoaling and anxiety behaviors depending on the treatment concentrations, and the underlying mechanisms are potentially associated with neuroinflammation and neuron apoptosis.
