Antioxidative and immunological response of shrimp Litopenaeus vannamei to combined stress of acute cold exposure and waterless duration: Implications for live transport

Aquaculture Research (2021)

Defeng Xu Jiaxin Wu Lijun Sun Xiaoming Qin Xiuping Fan

High mortality is a common phenomenon for live transport of shrimp Litopenaeus vannamei, and the biochemical mechanism underlying mortality remains incompletely known. This investigation explored the effect of combined stress of acute cold exposure (AC) and waterless duration (WD) on survivability, oxidative stress, antioxidative and immunity defence responses, and histological impairments. The survival profiles showed no significant difference between normal control (NC) and AC groups. The shrimps exposed to AC + WD stress, however, exhibited significantly higher mortality (p < 0.05) since 6 h afterwards, and the median survival probability was observed at 10.46 h. Overall, both the homeostasis of antioxidative and immunological response were disturbed in a duration time-dependent manner, and the impairment on hepatopancreas was observed. Significantly, the indicators of total haemocyte count (THC), viable haemocyte count (VHC) and peroxidase (POD) decreased while the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), phenol oxidase (PO), alanine transaminase (ALT) and aspartate transaminase (AST) increased (p < 0.05). Together, correlation analyses indicated that high mortality of L. vannamei was resulted from the disorder of antioxidative and immunological response. This study deepens our understanding into mortality of L. vannamei during waterless live transport.

Response mechanism of ♀ Epinephelus fuscoguttatus × ♂ Epinephelus lanceolatus under low-temperature and waterless stresses using TMT proteomic analysis

PROTOPLASMA (2021)

Xiuping Fan Qiaoyu Guo Jiasheng Zhang Huan Du Xiaoming Qin

♀Epinephelus fuscoguttatus × ♂Epinephelus lanceolatus, a hybrid grouper created from artificial breeding, has been widely developed over the past decades. However, the study focusing on lukewarm high-protein-content fish species using advanced techniques has rarely been reported. In this work, the TMT (tandem mass tag)-assisted technique was employed to explore its differentially expressed proteins and response mechanisms under low-temperature dormant and waterless stresses. Our findings suggest that 162 and 258 differentially expressed proteins were identified under low-temperature dormant and waterless stresses, respectively. The waterless preservation treatment further identifies 93 differentially expressed proteins. The identified proteins are categorized and found to participate in lipid metabolism, glycometabolism, oxidative stress, immune response, protein and amino acid metabolism, signal transduction, and other functions. Accordingly, the factors that affect the response mechanisms are highlighted to provide new evidences at protein level.

Extraction, purification, and structure characterization of polysaccharides from Crassostrea rivularis

Food Science & Nutrition (2018)

Xiaoming Qin Xiuping Fan Lianyi Zhang Huina Zheng Chaohua Zhang

Crude polysaccharide was prepared from Crassostrea rivularis by 30% (w/v) potassium hydroxide solution at 90°C for 120 min. Three fractions (OG1, OG2, and OG3) were purified by DEAE-52 cellulose and Sepharose 2B gel column chromatography. The chemical structures were determined using gas chromatography (GC), high-performance gel permeation chromatography (HPGPC), Fourier-transform infrared (FT-IR) spectroscopy, and 1H and 13C nuclear magnetic resonance (NMR) spectroscopy. The results indicated that OG1 was composed of rhamnose and little mannose (8.71%), the ratio of Rha: Gal: Xyl: Fuc in OG3 were 14:5.5:3:1. And their average molecular weights (Mw) were about 1.66 × 106 and 2.33 × 106 Da, respectively. OG2 was composed only of glucose (98.23%), which means it was glycogen. OG2 was consisted mainly of →4)- α-D-Glc-(1→, with the branch chain every 6.5 glucose residues on average, which is →4,6)-α-D-Glc-(1→ and trace amount of α-D-Glc-(1→ branched units. The Mw was 2.27 × 106 Da. It provides the bases for the bioactivity research.
