Their production has been historically accepted to derive mostly from marine microbes. This long-standing dogma has been challenged recently by the discovery that numerous invertebrates, mostly with an aquatic life-style, have the enzyme machinery necessary for the de novo biosynthesis of polyunsaturated fatty acids (PUFA) and, from them, LC-PUFA. The key breakthrough was the detection in these animals of enzymes called “methyl-end desaturases” enabling PUFA de novo biosynthesis. Moreover, other enzymes with pivotal roles in LC-PUFA biosynthesis, including front-end desaturases and elongation of very long- chain fatty acids proteins, have been characterised in several non-vertebrate animal phyla. This review provides a comprehensive overview of the complement and functions of these gene/protein families in aquatic animals, particularly invertebrates and fish. Therefore, we expand and re-define our previous revision of the LC-PUFA biosynthetic enzymes present in chordates to animals as a whole, discussing how key genomic events have determined the diversity and distribution of desaturase and elongase genes in different taxa. We conclude that both invertebrates and fish display active, but markedly different, LC-PUFA biosynthetic gene networks that result from a complex evolutionary path combined with functional diversification and plasticity.</p></div>","PeriodicalId":20650,"journal":{"name":"Progress in lipid research","volume":"86 ","pages":"Article 101157"},"PeriodicalIF":13.6,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0163782722000121/pdfft?md5=82fbfb7104670ef251d3349771139be2&pid=1-s2.0-S0163782722000121-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39740633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alongside these diseases, nutrition is associated with the prevalence of brain disorders. Although clinical and epidemiological studies revealed that metabolic diseases and brain disorders might be related, the underlying pathology is multifactorial, making it hard to determine causal links. Neuroinflammation can be a result of unhealthy diets that may cause alterations in peripheral metabolism.

As lipids in common foods exist in the form of emulsions, the structuring of emulsions has been one the main strategies for controlling the rate of lipid digestion and absorption, at least from a colloid science viewpoint. Modulating the kinetics of lipid digestion and absorption offers interesting possibilities for developing foods that can provide control of postprandial lipaemia and control the release of lipophilic compounds. Food emulsions can be designed to achieve considerable differences in the kinetics of lipid digestion but most research has been applied to relatively simple model systems and in in vitro digestion models. Further research to translate this knowledge into more complex food systems and to validate the results in human studies is required. One promising approach to delay/control lipid digestion is to alter the stomach emptying rate of lipids, which is largely affected by interactions of emulsion droplets with the food matrices. Food matrices with different responses to the gastric environment and with different interactions between oil droplets and the food matrix can be designed to influence lipid digestion.

The postprandial activity of LPL declines in oxidative tissues but rises in WAT, directing TG to WAT; the reverse is true during fasting. However, the molecular mechanism in regulating tissue-specific LPL activity during the fed-fast cycle has not been completely understood. Research on angiopoietin-like (ANGPTL) proteins (A3, A4, and A8) has resulted in an ANGPTL3-4-8 model to explain the TG partitioning between WAT and oxidative tissues. Food intake induces A8 expression in the liver and WAT. Liver A8 activates A3 by forming the A3-8 complex, which is then secreted into the circulation. The A3-8 complex acts in an endocrine manner to inhibit LPL in oxidative tissues. WAT A8 forms the A4-8 complex, which acts locally to block A4's LPL-inhibiting activity. Therefore, the postprandial activity of LPL is low in oxidative tissues but high in WAT, directing circulating TG to WAT. Conversely, during fasting, reduced A8 expression in the liver and WAT disables A3 from inhibiting oxidative-tissue LPL and restores WAT A4's LPL-inhibiting activity, respectively. Thus, the fasting LPL activity is high in oxidative tissues but low in WAT, directing TG to the former. According to the model, we hypothesize that A8 antagonism has the potential to simultaneously reduce TG and increase HDL-cholesterol plasma levels. Future research on A3, A4, and A8 can hopefully provide more insights into human health, disease, and therapeutics.</span></span></span></p></div>","PeriodicalId":20650,"journal":{"name":"Progress in lipid research","volume":"85 ","pages":"Article 101140"},"PeriodicalIF":13.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9699507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
