“…However, in the present study, TP did not change the HFD-induced decrease of MUFA in muscle. Of note, the dietary TP dose (50 and 200 mg/kg) used in the present study is lower than the doses, which were calculated by the contents of polyphenolic compounds in the dietary tea used in rainbow trout (Welker et al, 2016) and channel catfish (Zhang et al, 2014).…”

“…However, in the present study, the dietary TP did not change the HFD‐induced lipid accumulation. Some studies reported that the presence of antioxidants, such as TP, could increase the antioxidant potential and improve muscle fatty acid profile, including reducing saturated fatty acid content and increasing unsaturated fatty acid content, in rainbow trout (Welker et al., 2016) and channel catfish (Zhang et al., 2014). However, in the present study, TP did not change the HFD‐induced decrease of MUFA in muscle.…”

In aquaculture, the wide use of high-fat diet (HFD) could save protein and reduce feed costs, but also cause lipid deposition and impair flesh quality in fish. We hypothesized that tea polyphenols (TP) could alleviate the adverse effects of HFD on flesh quality in fish; thus, in the present study, GIFT tilapias were fed with control diet (60 g/kg fat), HFD (120 g/kg fat) and the HFD supplemented with two doses of TP (50 and 200 mg/kg, respectively) for 8 weeks. As compared with the control,

“…Many studies have confirmed that TPs have the inhibitory effect on cell-mediated immune response. In addition, studies have reported that dietary TPs can enhance non-specific humoral and cellular immune responses and improve disease resistance (Harikrishnan et al, 2011;Hwang et al, 2014;Sheikhzadeh et al, 2011;Zhang, 2015). Harikrishnan et al ( 2011) studied that oral green tea could also enhance the body fluid and cell-mediated response to Vibrio carinii infection in an antigen-free manner.…”

Molecular mechanisms and applications of tea polyphenols: A narrative review

Tea not only has a beloved taste, but also has rich biological activity, so it has become one of the best-selling beverages in the world. In the existing studies on tea, it is found that TPs account for highest proportion, which is the main bioactive ingredient. Generally, green tea polyphenols (GTP S ) are the main research materials, which are high in catechins. GTP S have significant health benefits (Xing et al., 2019) and are considered to be safe by the US Food and Drug Administration (Chang et al., 2019). Since the 1950s, scholars have begun to study the biological activity of TPs and their mechanism of action, and found that TPs are not only beneficial to human health, but also have an impact on food, medical, chemical and other fields.According to the research on the components of TPs (Khan & Mukhtar, 2018;Li et al., 2019), it is found that TPs contain catechins, flavonoids, anthocyanins, phenolic acids and other substances, among which catechins account for the largest proportion, up to 60%-80%. Catechin is divided into epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC) and epigallocatechin gallate (EGCG; the molecular structure is shown in the Figure 1). The content relationship is EGCG > EGC > ECG > EC, of which EGCG accounts for about 70%. Therefore, EGCG is the main catechin and the research on the biological activity of TPs mainly starts from EGCG.The research conclude that TPs can exert a variety of biological activities such as anti-oxidation, anti-tumor, anti-inflammation,

“…Previous reports found that TPs decreased low-density lipoprotein, total cholesterol, and triacylglycerol | 5045 contents (Nanjo et al, 1994), restrained body and liver fat accumulation (Huang et al, 2017;Rothenberg et al, 2018). Dietary TPs supplement was described to enhance growth rate (Abdel-Tawwab et al, 2010), and improve resistance to disease in fish (Zhou et al, 2015). It has also been observed that TPs promoted growth, weight gain rat and Hepato-somatic index (HSI) and reduced liver fat deposition in turbot (Scophthalmus maximus) fish (Yicong et al, 2019).…”

Several studies have highlighted the effect of Tea polyphenol (TPs) on growth performance and the gene regulation associated with the metabolic pathway and of various species. However, there is less information about the effect of TPs on growth performance and the regulation of genes related to the metabolic pathway of Grass carp (Ctenopharyngodon idellus). Six diets with different TPs level (0, 250, 500, 1,000, 2,000 and 4,000 mg/kg) were formulated. Result found that TPs increased the feed conversion efficiency (FCE) at different levels, and the highest FCE and specific growth rate (SGR) (p < 0.05) were achieved by the 500 mg/kg in the TPs group. Additionally, transcriptome sequencing of control and TPs groups was performed, and numerous differentially expressed genes (DEGs) were determined in the metabolic pathway of grass carp. The differentially expressed genes were validated by the qRT-PCR technique. DEGs were associated with arachidonic acid metabolism, linoleic acid metabolism, alpha-linolenic acid metabolism, biosynthesis of unsaturated fatty acids, fatty acid biosynthesis and fatty acid degradation. Our findings could provide new insight into the effect of TPs on growth performance and the regulation of genes associated with the metabolic pathway of grass carp.
