“…In general, reduced HUFA biosynthesis in yellow catfish, especially for DHA and EPA, would not be desirable in aquaculture, particularly if dietary fish oils rich in HUFA are replaced with HUFA-deficient plant oils. In the present study, despite reduced weight gain and whole body lipid content with increasing dietary CLA levels, the incorporation of the two biologically active CLA isomers (trans-10, cis-12 and cis-9, and trans-11) into the whole body was still proportional to dietary CLA levels (data not shown), in agreement with several studies (Bandarra et al, 2006;Valente et al, 2007b). Thus, our results indicate that like other freshwater species, yellow catfish can successfully incorporate CLA into the whole body, contributing to the production of a functional food, because dietary CLA has been reported to elicit potential health benefits related to its anti-cancer properties ) and anti-atherosclerosis (Lee et al, 1994).…”

“…However, at present, little information is available on the effect of dietary CLA on whole body PUFA profiles in fish, and many studies were conducted in fatty acid profile changes in liver and muscle, which showed some contradictory results. For example, high dietary CLA levels led to the increase of 18:2n−6 and EPA deposition (Valente et al, 2007b), and the increase of EPA and DHA in salmon liver (Leaver et al, 2006). In contrast, Diez et al (2007) detected lowered hepatic EPA levels, and raised levels of the precursor fatty acid 18:3n−3 following CLA intake.…”

“…Dietary CLA seemed to slightly depress both ME and G6PD activities, whereas liver lipid content tended to increase in large yellow croaker fed with high CLA. The similar results were evidenced in rainbow trout (Valente et al, 2007a) and sea bass (Valente et al, 2007b), in which the malic enzyme activity decreased with CLA supplementation. Other studies showed a clear increase in both mRNA expression and activities of various enzymes involved in lipogenesis (including ME, G6PD and FAS) and fatty acid oxidation in mice liver (Takahashi et al, 2003;Ide, 2005).…”

Zhao et al. / J Zhejiang Univ Sci B 2008 9(9)Abstract: We examined the effects of conjugated linoleic acid (CLA) on growth, fatty acid composition and enzyme activity of fatty acid oxidation in the liver of large yellow croaker. We divided 1600 fish (average initial weight 150 g) into 4 groups and reared them in 8 cages. Four dietary treatments were formulated to contain 0%, 1%, 2% and 4% (w/w) CLA, respectively. The fish were fed for 10 weeks ad libitum twice daily. We found that the dietary CLA had no effect on growth, biometric parameters and whole body proximate (P>0.05), but showed some significant effects on the fatty acid composition in both muscle and the liver. The activities of lipogenic enzymes were slightly depressed in fish fed with increasing levels of CLA when compared with control (P>0.05). Dietary CLA supplementation had no effects on liver lipid content, but significantly increased the contents of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) (P<0.05) and decreased monounsaturated fatty acid (MUFA) content in both muscle and the liver. Dietary CLA inclusion resulted in significant increases of the biologically active cis-9, trans-11 and trans-10, cis-12 isomers in both tissues (P<0.05). The total accumulation of CLA was higher in the liver (3.83%, w/w) than in muscle (3.77%, w/w) when fed with 4% (w/w) CLA. This study demonstrates that large yellow croakers are capable of absorbing and depositing CLA and long-chain n-3 PUFA in the liver and muscle, showing that this species fed with CLA could be an important human food source for these healthful fatty acids.

“…It has been reported that lipogenic enzymes are affected by dietary protein/energy ration (Dias et al 1998), specific fatty acids (Valente et al 2007), and other dietary components (Likimani and Wilson 1982). To our knowledge, the present experiment is the first trial to confirm the influence of ascorbate on the lipogenic enzyme activity.…”

To assess the effect of dietary ascorbate on lipid metabolism, 1-year black sea bream (Acanthopagrus schlegelii) were reared on a casein-based purified diet and an ascorbate fortified diet (1,100 mg of L: -ascorbyl-2- monophosphate-Mg/kg diet). The fortified ascorbate was effectively incorporated into the fish body and elevated muscle carnitine content. Fortifications of dietary ascorbate depressed activities of glucose-6-phosphate dehydrogenase and NADP-isocitrate dehydrogenase as lipogenic enzymes in the hepatopancreas and intraperitoneal fat body. Starvation after feeding experiment activated carnitine palmitoyltransferase as a lipolysis enzyme in the hepatopancreas in both control and vitamin C(VC) groups, while the lipolysis activity was significantly higher in VC group. These results confirmed that dietary ascorbate depressed lipogenesis and activated lipolysis, i.e., influenced the lipid metabolism of black sea bream.
