| dc.description.abstract | In this study, goldfish demonstrate preference for high carbohydrate and high fat diets, with no preference shown for high protein diets. Fish fed high (45% and 55%) carbohydrate (CHO) diets for 1 and 4 weeks exhibited decreased NPY gene expression in telencephalon–preoptic area (TEL–POA) and optic tectum–thalamus (OT–THAL) compared to fish fed low CHO (35% and 40%) diets. In hypothalamus (HYP), NPY gene expression was significantly increased after 1 week in fish fed both low and high CHO diets compared to control diet (40% CHO); after 4 weeks, the pattern in HYP was reversed. Fish fed a high fat (9%) diet had low NPY gene expression in TEL–POA after 1 and 4 weeks; however, HYP NPY expression was increased in fish fed a low (3%) fat diet after 1 week, and 2% and 3% fat diets after 4 weeks. In OT–THAL, NPY gene expression was decreased in fish fed a 2% fat diet for 1 week, and increased after 4 weeks. Feeding diets with different protein contents for 1 or 4 weeks did not influence NPY gene expression in goldfish brain. The results demonstrate, for the first time in a lower vertebrate, that NPY gene expression in goldfish brain is influenced by macronutrient intake. | |
