In this study, the alleviative effects of chlorogenic acid (CGA) on oxidative stress, inflammation and apoptosis of amur ide (Leuciscus waleckii) induced by lipopolysaccharide (LPS) were evaluated. Using a 2 × 2 factorial design, amur ide were irregularity divided into 4 groups and fed two diets with 0.00 % (CK and LPS), 0.

The study investigated the potential alleviating effect of sodium butyrate (SB) on intestinal injuries caused by glycinin in the diet of common carp. Fish were divided into six groups: a control group (without glycinin and SB), a Gly group (with glycinin), and four groups supplemented with different doses of SB (0.75, 1.

In this experiment, we investigated the effects of adding chlorogenic acid (CGA) to the diet on growth performance, immune function, inflammation response, antioxidant capacity and its related mechanisms of common carp (Cyprinus carpio). A total of 600 fish were selected and randomly divided into five treatment groups and fed with CGA containing 0 mg/kg (CK), 100 mg/kg (L100), 200 mg/kg (L200), 400 mg/kg (L400) and 800 mg/kg (L800) for 56 days. The results of the experiment were as follows: addition of CGA significantly increased the WGR, SGR, FER, and PER of common carp (P < 0.

Article Synopsis
  • A study was conducted to explore how sodium butyrate (SB) affects inflammation, oxidative stress, and growth issues in common carp caused by glycinin.
  • Six different diets were tested, with those containing 1.50-2.25 g/kg of SB showing significant improvements in feed efficiency and reversing growth inhibition linked to glycinin.
  • SB also enhanced immune functions and reduced inflammation by modifying the mRNA levels of immune-related genes and activating specific cellular pathways in the carp.

Article Synopsis
  • * A study with 450 juvenile common carp tested varying dietary levels of NAC over 8 weeks, showing that higher levels (3.0-6.0 g/kg) reduced harmful lipid vacuoles, prevented cell death, and improved liver health.
  • * The research revealed that NAC boosted the immune function and antioxidant capacity of the carp by activating certain signaling pathways, suggesting its potential benefits for fish health in aquaculture.

In this study, the alleviative effects of poly-β-hydroxybutyrate (PHB) in bioflocs on oxidative stress, inflammation and apoptosis of common carp (Cyprinus carpio) induced by lipopolysaccharide (LPS) were evaluated. Common carp were irregularity divided into 5 groups and fed five diets with 0 % (CK), 2 %, 4 %, 6 % and 8 % PHB. After 8-week feeding trial, LPS challenge was executed.

Article Synopsis
  • Interleukin-16 (IL-16) is a key cytokine that influences immune responses and bacterial defense, but its effects in fish, specifically the tongue sole, are not well understood.
  • The study identified a homologue called CsIL-16, which consists of 1181 amino acids and shows varying similarities to IL-16 from other species.
  • Recombinant CsIL-16 demonstrated the ability to enhance the function of immune cells and effectively inhibit the bacteria E. tarda, highlighting its significant role in antibacterial immunity in fish.

To investigate the role of the Rab7 effector RILP (Rab-interacting lysosomal protein) in white spot syndrome virus (WSSV) infection, the full-length cDNA of RILP (LvRILP) was cloned in Litopenaeus vannamei, which consists of 1595 bp and encodes a polypeptide of 411 amino acids. Sequence analysis and multiple sequence alignment displayed that LvRILP contained a conserved RILP region from 277 amino acid to 325 amino acid. Both the LvRILP and Rab7 mRNA were most highly expressed in stomach and most lowly expressed in hemocyte, which were significantly up-regulated and exhibited similar kinetics post WSSV infection.

In this study, GST Pull-down and mass spectrometry was applied to the precipitation and identification of the small GTP-binding protein (Rab7) interacting protein in hemocyte of Litopenaeus vannamei. According to the search in GenBank with the peptide mass fingerprint, the 45 kDa protein which was pulled down with the GST-tagged Rab7 (GST-Rab7, GTP bound form) was identified to be β-actin with 28% coverage of amino acid sequences. The interaction of Rab7 with β-actin was verified by both GST Pull-down and ELISA in vitro.
