“…PPARs family is an important transcription factor regulating metabolic balance, glucose, lipid and energy metabolism, insulin sensitivity, etc (Gross et al., 2017). In present study, differences in PPARs expressions were also affected among treatments, which likely resulted in different efficiency of lipid metabolism (Sarameh et al., 2019). This was indicted that PPARs genes were highly influenced by dietary lipid sources.…”

“…PPARγ regulates the transcription of multiple genes involved in the differentiation of lipid precursor cells, regulates the glucose uptake of insulin‐mediated peripheral tissues and increases insulin sensitivity (Ren et al., 2018). At the same time, PPARs expression also has tissue specificity (Shi et al., 2002) and plays different roles in lipid and energy dynamics and has different expression patterns (Sarameh et al., 2019). In addition, the concentration and proportion of FAs in feedstuffs from different oil sources were different in present study, which had different effects on various PPAR subtypes.…”

“…It can transport FA from cell membrane to intracellular utilization site and plays an important role in FA metabolism (Di Pietro & Santomé, 2001). However, there are few studies on the effects of lipid sources on lipid metabolism and PPARs or FABP family genes in fish (Sarameh et al., 2019).…”

An 8‐week growth trial was conducted to evaluate effects of dietary oil sources on growth, enzymes activity and genes expression levels related to lipid metabolism of hybrid grouper (♀Epinephelus fuscoguttatus × ♂E. lanceolatu) juveniles. Seven iso‐lipid (97 g/kg of dry matter) and iso‐protein (503.5 g/kg of dry matter) experimental diets were formulated containing 50 g/kg fish oil (FO; acting as controls) or various vegetable oils (VOs): corn oil (CO), sunflower oil (SO), tea oil (TO), olive oil (OO), rice oil (RO) and mixed oil (MO; comprising equal amounts of these oils). Each diet was fed to triplicate groups of 40 fish for per repetition (15.09 ± 0.01 g) for 56 days. The results show that (a) alternative dietary oils had no significant effects on final weight compared with control group (p > .05); (b) compared with FO group, VOs significantly changed the contents of serum lipoproteins, cholesterol, triglycerides and the activity of liver lipid‐metabolizing enzymes (p < .05); (c) CO group had the least effect on the serum lipoproteins, triglycerides and cholesterol of grouper compared with control; the activity of liver lipid‐metabolizing enzymes in RO and control group was the closest; (d) the mRNA levels of Δ6 Fatty acid desaturase (Δ6Fad), hormone‐sensitive lipase (HSL) and lipoprotein lipase (LPL) were not significantly effected by lipid sources, but CO, TO, OO and MO significantly down‐regulated the expression of fatty acid synthetase (FAS) mRNA level in liver, while RO opposite (p < .05); (e) vegetable oil significantly up‐regulated peroxisome proliferator‐activated receptor α (PPARα) and peroxisome proliferator‐activated receptor β (PPARβ) mRNA levels, while TO and RO down‐regulated peroxisome proliferator‐activated receptor γ (PPARγ) mRNA levels (p < .05); and 6) MO significantly increased the mRNA levels of heart‐type fatty acid‐binding protein (H‐FABP) and adipocyte‐type fatty acid‐binding protein (A‐FABP) (p < .05), while other VOs had no effect on them (p > .05). In conclusion, dietary substitution of FO by VO in diet affected lipid metabolism of grouper, which may be regulated by PPARs.

“…The gene expression of Apolipoprotein (APO) in ovary and embryos of Chinese sturgeon ( Acipenser sinensis ) indicates the suitability of the APO gene as a marker for endogenous lipid nutrition in the ontogenic study [ 113 ]. Sarameh et al [ 104 ] reported that Chinese sturgeon broodstock benefits from kilka fish oil and rapeseed oil mix in diets shown by upregulated APO expression with improved egg fertility and larval survival. Additionally, 18% dietary lipid can increase lipid deposition during vitellogenesis shown by upregulated expressions of fatty acid binding protein (FABP) and lipoprotein lipase (LPL) genes, which then stimulate the development of oocyte follicles to stage IV maturation [ 68 ].…”

Dietary lipid manipulation in the feed of commercially cultured finfish is used not only to improve production and culture but also to enhance their reproductive performances. The inclusion of lipid in broodstock diet positively affects growth, immunological responses, gonadogenesis, and larval survival. In this review, existing literature on the importance of freshwater finfish species to aquaculture and the inclusion of dietary lipid compounds in freshwater fish feed to accelerate the reproduction rate is being summarized and discussed. Although lipid compounds have been confirmed to improve reproductive performance, only a few members of the most economically important species have reaped benefits from quantitative and qualitative lipid studies. There is a knowledge gap on the effective inclusion and utilization of dietary lipids on gonad maturation, fecundity, fertilization, egg morphology, hatching rate, and consequently, larval quality contributing to the survival and good performance of freshwater fish culture. This review provides a baseline for potential future research for optimizing dietary lipid inclusion in freshwater broodstock diets.

“…Certain Fads and Elovl enzymes catalyse reactions of desaturation (insertion of new double bonds) and elongation (extension of fatty acyl chain in two carbons) by which C 18 PUFA are bioconverted into LC‐PUFA (Castro et al, 2016; Cook, 1996). In addition to Fads and Elovl, other key proteins involved in lipid transport, lipid absorption and FA bioconversion within lipid metabolism (Castro et al, 2015; Chen et al, 2020; Sarameh et al, 2019; Torstensen et al, 2000), as well as some transcription factors (TF) modulating their activity, are involved in the overall regulation of lipid metabolism. TF such as liver X receptor ( lxr ), peroxisome proliferator‐activated receptors ( ppar ) and sterol regulatory element‐binding proteins ( srebp ) have received much attention because of their crucial role in regulating the expression of genes involved in LC‐PUFA biosynthesis in both mammals and teleost fish (Daemen et al, 2013; Fievet & Staels, 2009; Monroig et al, 2018).…”

Given the ecological unsustainability of using fish oil (FO) as the main source of longchain polyunsaturated fatty acids (LC-PUFA), the investigation of alternative dietary LC-PUFA sources is crucial for aquaculture. Tambaqui (Colossoma macropomum) is a valuable economic aquaculture resource in Brazil, capable of endogenously elongating and desaturating linoleic (LA; 18:2n-6) and α-linolenic (ALA; 18:3n-3) acids to longer and physiologically vital LC-PUFA. Yet, it is unclear how this pathway is regulated by different oil sources in tambaqui. Thus, we designed an experiment with 2 different oil diets (fish oil-FO and vegetable oil-VO) at 2 different concentrations (5% or 10%) to investigate the molecular regulation of fatty acid biosynthesis in this species. We observed no differences in survival, body weight gain (BWG) and feed conversion ratio between the treatments. Gene expression analysis shows that fads2 and elovl5 are upregulated in liver, while fads2 and elovl2 are up-regulated in brain of tambaqui fed with VO. The transcription factors pparβb and pparγ are also up-regulated in the brain by VO diet, when compared to FO diet. The VO diet also contributed to the biosynthesis of LC-PUFA in liver and specifically DHA in the brain. Overall, our approach shows that lipid metabolism-relevant genes are regulated by different dietary lipid sources.
