“…However, Nano-ZnO upregulated the expression of GCLM and GPx1 by decreasing the Keap1 expression, and increasing the Nrf2 expression and protein level in the nucleus, which was consistent with the results of the antioxidant-related enzyme activities. A recent study in rainbow trout reported that dietary supplementation of Nano-ZnO upregulated the expression of SOD1, SOD2, CAT and GPx1 by increasing Nrf2 gene expression ( 59 ), and we saw the same effect on IUGR finishing pigs. These results suggested that Nano-ZnO may enhance the antioxidant capacity of IUGR pigs by promoting Nrf2/Keap1 signal pathway in jejunal mucosa, improving the activity of related antioxidant enzymes, and reducing the generation of MDA and PC to alleviate oxidative stress.…”

This study was to investigate effects of zinc oxide nanoparticle (Nano-ZnO) on growth, immunity, intestinal morphology and function of intrauterine growth retardation (IUGR) finishing pigs. Six normal birth weight (NBW) and 12 IUGR male piglets were obtained and weaned at 21 d. NBW-weaned piglets fed basal diets (NBW group), IUGR-weaned piglets allocated to two groups fed basal diets (IUGR group) and basal diets further supplemented 600 mg Zn/kg from Nano-ZnO (IUGR+Zn group), respectively. All pigs were slaughtered at 163 d. Results showed: (1) IUGR pigs showed no difference in body weight at 77d and 163d (P > 0.05), while had increased villus height (VH) and villus surface area in jejunum (P < 0.05) and enhanced interleukin-6, TNF-α and NF-κB mRNA expression (P < 0.05) as compared to NBW group; Compared with IUGR group, dietary Nano-ZnO did not affect the body weight (P > 0.05), but increased VH to crypt depth ratio and IgA concentration (P < 0.05) and decreased TNF-α and NF-κB mRNA expression in jejunum (P < 0.05). (2) IUGR increased the number of swollen mitochondria and autolysosomes, and protein expressions of sequestosome-1 (P62) and microtubule-associated protein light chain 3 B/A (LC3B/A) in jejunum as compared to NBW group (P < 0.05); Compared with IUGR group, Nano-ZnO decreased the number of swollen mitochondria and autolysosomes, and P62 and LC3B/A protein expression (P < 0.05). (3) IUGR increased mucosal contents of malondialdehyde and protein carbonyl (PC) and Keap1 protein expression (P < 0.05) as compared to NBW group; Compared with IUGR group, dietary Nano-ZnO increased activities of total antioxidant capacity, catalase, glutathione peroxidase, and glutathione content (P < 0.05), and enhanced nuclear respiratory factor 2 (Nrf2), glutamate-cysteine ligase modifier subunit and glutathione peroxidase 1 mRNA expression, and increased total and nuclear Nrf2 protein expression (P < 0.05), and decreased malondialdehyde and PC content, and Keap1 protein expression (P < 0.05) in jejunum. Results suggested that IUGR pigs showed postnatal catch-up growth and improved intestinal morphology, and dietary Nano-ZnO may further improve intestinal morphology, reduce inflammation, decrease autophagy and alleviate oxidative stress via Nrf2/Keap1 pathway in jejunum of IUGR pigs.

“…In this study, DMY-Zn increased the enzyme activities of CAT, SOD in the serum, and CAT in the liver. Moreover, the activity of Cu/Zn-SOD was higher in DMY-Zn (organic) than that of ZnSO 4 (inorganic), which was similar to the finding in rainbow trout [60]. According to a previous study, organic Zn has a stronger antioxidant activity than inorganic Zn such as Zn glycine (Zn-Gly) enhanced serum T-AOC, AKP, and Cu/Zn SOD while lowering nitric oxide levels when compared to ZnSO 4 [61].…”

This study investigated the effect of different supplements of Zn on the growth performance, antioxidant, lipid metabolism, and element deposition of hybrid grouper (♀ Epinephelus fuscoguttatus × ♂ E. lanceolatus). A total of 180 juvenile groupers (bodyweight 10.02 ± 0.01 g) were divided into three groups of 20 fish each and fed with ZnSO4, nanozinc oxide (Nano-ZnO), and dihydromyricetin-Zn (DMY-Zn) for 8 weeks(the content of Zn were 123,122.11, and 120.72 mg/kg). The findings revealed that DMY-Zn had a substantial impact on growth, feed conversion ratio, and protein efficiency ratio, whereas Nano-ZnO had a significant impact on feed conversion ratio and protein efficiency ratio. Furthermore, DMY-Zn had a positive effect on the high-density lipoprotein (HDL) content and significantly upregulated the lipid synthesis gene expression (FASN and ACACA) in the liver. The fish fed DMY-Zn had larger levels of catalase (CAT) in both the serum and liver, as well as Cu/Zn-superoxide dismutase (SOD) enzymes in muscle. In terms of antioxidant-related gene expression, the DMY-Zn treatment upregulated the expression of SOD1, Keap1b, and Mt2. Moreover, DMY-Zn also had a prominent effect on element deposition, increasing the concentration of Fe and Zn in the fish liver and muscle and Cu only in the fish muscle. The results revealed that a fish-fed diet enriched with DMY-Zn had significantly higher antioxidant and lipid metabolism activities than a ZnSO4-fed diet. In conclusion, dietary DMY-Zn treatment appears to be effective in increasing hybrid grouper growth, element deposition, antioxidant activity, and lipid metabolism.
