Fish intestine is very sensitive to oxidative damage. Repair of damaged enterocytes may be involved to restore normal function of fish intestine. However, studies of fish enterocyte repair are scarce. The present study aimed to investigate the potential repair role of glutamine after a H2O2 challenge. In this study, fish enterocytes were post-treated with(More)
In the present study, we tested the hypothesis that dietary histidine could improve antioxidant capacity of juvenile Jian carp (Cyprinus carpio var. Jian). A total of 1,200 juvenile Jian carp were fed graded levels of histidine at 2.3 (unsupplemented control), 4.4, 6.3, 8.6, 10.8 and 12.7 g/kg diet for 60 days. Results showed that the content of(More)
The present study explored the effects of alanine (Ala), citrulline (Cit), proline (Pro) and their combination (Ala10Pro4Cit1) on the activities of caspases and levels of reactive oxygen species (ROS) and cytochrome c in hydroxyl radicals (•OH)-induced carp erythrocytes. The data displayed that •OH induced the increases in the activities of caspase-3,(More)
There are young erythrocytes and mature erythrocytes in the peripheral blood of fish. The present study explored the apoptosis in hydroxyl radical (·OH)-induced young and mature erythrocytes of Jian carp (Cyprinus carpio var. Jian). Carp erythrocytes from the peripheral blood were separated into the young fraction, the intermediate fraction and the mature(More)
The present study aimed to assess the possible preventive and reparative effects of isoleucine (Ile) against copper (Cu)-induced oxidative stress in fish enterocytes in vitro. In experiment 1, enterocytes were preincubated with increasing concentrations of Ile (0, 50, 120, 190, 260, and 330 mg L−1) for 72 h followed by exposure to 6 mg L−1 Cu for 24 h. In(More)
Lipid peroxidation, protein oxidation and antioxidant activities of muscle, intestine, hepatopancreas and serum in juvenile Jian carp (Cyprinus carpio var. Jian) were investigated after feeding graded levels of biotin (0.010, 0.028, 0.054, 0.151, 0.330, 1.540 and 2.680 mg kg−1 diet) for 63 days. Both malondialdehyde and protein carbonyl content in all(More)
This study was carried out to investigate effects of threonine levels on growth, digestive and absorptive capacity and antioxidant status in intestine and hepatopancreas of sub-adult grass carp (Ctenopharyngodonidella). Weight gain, specific growth rate, feed intake and feed efficiency were significantly improved by dietary threonine (P < 0.05). Intestinal(More)
