Abstrakt: Trace amines and their receptors are a family of G protein-coupled receptors widely distributed in the central nervous system and periphery. The trace amine-associated receptor 1 (TAAR1) plays a significant role as a therapeutic target for schizophrenia, depression, diabetes, and obesity. In this study, TAAR1 knockout mice and WT groups were tested in conditions of a high-fructose diet. The consumption of a high-fructose diet may be due to the influence on the metabolism processes by dopamine in the brain, neuromotor function, and level of anxiety of TAAR1 knockout mice. During a comparative analysis of behavioral, biochemical, and morphological parameters, significant differences were found between liver and biochemical parameters, the regulation of protein metabolism (AST/ALT ratio, creatine kinase activity, urea), and alterations in behavior. An elevated plus maze analysis showed the influence of fructose and genetic factors on the level of anxiety. A new marker of the grooming microstructure (depression ratio) was tested, which showed high efficiency as a marker of depression-like behavioral changes and a possible association with dopamine-dependent regulation of protein metabolism. These results confirm a possible association of the TAAR1 gene knockout with an increase in catabolic reaction levels by AST/ALT-dependent and possible dopamine-mediated protein metabolism regulation and depression-like behavior.
