Dietary vegetable oils: Effects on the expression of immune-related genes in Senegalese sole (Solea senegalensis) intestine

Replacement of Marine Fish Oil with de novo Omega‐3 Oils from Transgenic Camelina sativa in Feeds for Gilthead Sea Bream (Sparus aurata L.)

“…In this respect, fish gut epithelium acts and reacts as the first line of protection against potentially harmful substances in the diet, with VO causing changes in fish that could favour intestinal dysfunction, including alterations in the gut associated immune system [81]. Thus, down-regulation of il8 in intestine of VO-fed fish confirmed the importance of dietary fatty acid profile on the immune system of marine fish in agreement with previous studies [80, 82]. In contrast, liver of DCO-fed fish showed higher expression of il8 , albeit not different to expression in liver of bream fed the other VO diets, which may indicate that the VO fatty acid profile may enhance il8 activity in this tissue.…”

Eicosapentaenoic Acid, Arachidonic Acid and Eicosanoid Metabolism in Juvenile Barramundi Lates calcarifer

“…In agreement with many vertebrates, nutritionally inducible COX2 genes have been identified in several teleost species (Ishikawa and Herschman, 2007;Ishikawa et al, 2007a;Montero et al, 2015a;Olsen et al, 2012;Rouzer and Marnett, 2009;Yuan et al, 2015;Zuo et al, 2015). The role of COX2 as an active and rapidly inducible gene has undoubtedly played a role in the modified metabolic function of the ARA fed fish during the present study.…”

Partial or total replacement of dietary fish oil with alternative lipid sources in silvery-black porgy (Sparidentex hasta)

“…lysozyme and alternative complement activity) responses (Montero et al, 2003;, lipid peroxidation (Yaqoob and Calder, 2007), eicosanoid production (Ganga et al, 2005;Mourente et al, 2007) and regulation of gene expression (Montero et al, 2008(Montero et al, , 2010(Montero et al, , 2015. In the current study, fish fed the T diet had the lowest plasma hemolytic and antibacterial activities.…”

“…Nevertheless, not all species necessarily respond equally to dietary FO replacements and although these generalizations may be used as a benchmark, effects of dietary alternative lipid sources should be evaluated on a case by case basis (Turchini et al, 2009;Sales and Glencross, 2011;Nasopoulou and Zabetakis, 2012). However, fish health can be affected by manipulating of the dietary fatty acids (FA) with different lipid sources because of marked changes in the FA composition of the immune cells (Montero et al, 2015). Thus, besides fish growth performance and carcass nutrient components, general health of fish also should be considered when using different alternative lipid sources.…”
