A 12-week feeding trial was performed to evaluate the effects of high-carbohydrate diet on oxidative stress, inflammation and apoptosis induced by silver nanoparticles (Ag-NPs) in M. amblycephala. Fish (20.12 ± 0.85 g) were randomly fed four diets (one control diet (C, 30% carbohydrate), one control diet supplemented with 100 mg kg−1 Ag-NPs (CS), one high-carbohydrate diet (HC, 45% carbohydrate) and one HC diet supplemented with 100 mg kg−1 Ag-NPs (HCS)). The results indicated that weight gain rate (WGR), specific growth rate (SGR), antioxidant enzyme (SOD and CAT) activities and expression of Trx, Cu/Zn-SOD, Mn-SOD, CAT and GPx1 of fish fed CS diet were all remarkably lower than those of other groups, whereas the opposite was true for plasma IL 1β and IL 6 levels, liver ROS contents, hepatocytes apoptotic rate, AMP/ATP ratio, AMPKα, P 53 and caspase 3 protein contents and mRNA levels of AMPKα 1, AMPKα 2, TXNIP, NF-κB, TNFα, IL 1β, IL 6, P 53, Bax and caspase 3. However, high-carbohydrate diet remarkably increased WGR, SGR, liver SOD and CAT activities, AMPKα protein content and mRNA levels of antioxidant genes (Cu/Zn-SOD, Mn-SOD, CAT and GPx1), anti-inflammatory cytokines (IL 10) and anti-apoptotic genes (Bcl 2) of fish facing Ag-NPs compared with the CS group, while the opposite was true for liver ROS contents, hepatocytes apoptotic rate, P 53 and caspase 3 protein contents, as well as mRNA levels of TXNIP, NF-κB, TNFα, IL 1β, IL 6, P 53, Bax and caspase 3. Overall, high-carbohydrate diet could attenuate Ag-NPs-induced hepatic oxidative stress, inflammation and apoptosis of M. amblycephala through AMPK activation.

Expensive and unsustainable fishmeal is increasingly being replaced with cheaper lipids and carbohydrates as sources of energy in aquaculture. Although it is known that the excess of lipids and carbohydrates has negative effects on nutrient utilization, growth, metabolic homeostasis, and health of fish, our current understanding of mechanisms behind these effects is limited. To improve the understanding of diet-induced metabolic disorders (both in fish and other vertebrates), we conducted an eight-week high-fat–high-carbohydrate diet feeding trial on blunt snout bream (Megalobrama amblycephala), and studied gene expression changes (transcriptome and qPCR) in the liver. Disproportionately large numbers of differentially expressed genes were associated with mitochondrial metabolism, neurodegenerative diseases (Alzheimer’s, Huntington’s, and Parkinson’s), and functional categories indicative of liver dysfunction. A high-fat–high-carbohydrate diet may have caused mitochondrial dysfunction, and possibly downregulated the mitochondrial biogenesis in the liver. While the relationship between diet and neurodegenerative disorders is well-established in mammals, this is the first report of this connection in fish. We propose that fishes should be further explored as a potentially promising model to study the mechanisms of diet-associated neurodegenerative disorders in humans.

Abstract Background: The impairment of immunity induced by high-carbohydrate diet is closely associated with the development of glucose metabolic disorders. In the study of diabetes, benfotiamine can prevent β-cell dysfunction by inhibiting inflammation, thereby improving insulin resistance. However, information regarding the effects of this substance on aquatic animals is extremely scarce.Methods: A 12-week nutritional research was conducted to evaluate the influences of benfotiamine on the growth performance, oxidative stress, inflammation and apoptosis in Megalobrama amblycephala (45.25 ± 0.34 g) fed high-carbohydrate (HC) diets. Six experimental diets were formulated, containing a control diet (30% carbohydrate, C), a HC diet (43% carbohydrate), and the HC diet supplemented with four graded benfotiamine levels (0.7125 (HCB1), 1.425 (HCB2), 2.85 (HCB3), and 5.7 (HCB4) mg/kg).Results: HC diet intake remarkably decreased daily growth coefficient (DGC), growth rate per metabolic body weight (GRMBW), feed intake (FI), liver antioxidant enzymes activities, sirtuin-1 (SIRT1) protein expression as well as liver mRNA levels of SIRT1, nuclear factor erythroid 2-related factor 2 (Nrf2), catalase (CAT), manganese superoxide dismutase (Mn-SOD), interleukin10 (IL10) than those of the control group, but the opposite was true for plasma activities of alanine transaminase (AST) and aspartate aminotransferase (ALT), and contents of interleukin 1β (IL1β) and interleukin 6 (IL6), liver contents of malondialdehyde (MDA), and mRNA levels of kelch-like ECH associating protein 1 (Keap1), nuclear factor kappa B (NF-κB), tumour necrosis factor α (TNF α), IL1β, IL6, Bax, Caspase 3, Caspase 9 and P53. As with benfotiamine supplementation, HCB2 diet remarkably increased DGC, GRMBW, liver antioxidant enzymes activities, SIRT1 protein expression as well as liver mRNA levels of SIRT1, Nrf2, CAT, Mn-SOD, IL10 and Bcl2, while the opposite was true for plasma activities of AST and ALT, and contents of IL1β and IL6, liver MDA contents as well as mRNA levels of Keap1, NF-κB, TNF α, IL1β, IL6, Bax, Caspase 3, Caspase 9 and P53.Conclusion: Benfotiamine at 1.425 mg/kg can improve the growth performance and alleviate the oxidative stress, inflammation and apoptosis of M. amblycephala fed HC diets through the activation of the SIRT1 pathway.
