The relative expression of phosphorylated p38, JNK and ERK in mice liver with GABA treatment were reduced to 65 %, 39 % and 80 % of the control group, respectively.

Xanthophylls, one of the main groups of carotenoids, have been proposed as preventive agents or adjunct therapies to prevent and slow the progression of atherosclerosis due to their cardioprotective properties. However, the underlying preventive mechanism of action of xanthophylls on the pathogenesis of atherosclerosis remains unclear, and clinical evidence of the effect of xanthophylls on atherosclerosis have not yet been summarized and critically reviewed. In this regard, we conducted a comprehensive literature search in four scientific databases (PubMed, Google Scholar, ScienceDirect and Web of Science) and carefully analyzed the existing evidence to provide meaningful insights on the association between xanthophylls and atherosclerosis from various aspects. Based on the evidence from <em>in vitro</em> and <em>in vivo</em> studies, we explored several potential mechanisms, including antioxidant effect, anti-inflammatory effect, regulation of lipid metabolism, and modulation of ECs and VSMCs dysfunction, and we found that a clear picture of regulatory pathways of xanthophylls on atherosclerosis prevention and treatment is still lacking. In addition, epidemiological studies suggested the possible relationship among high dietary intake of xanthophylls, high plasma/serum xanthophylls and a reduced risk of atherosclerosis. Direct evidence from interventional studies investigating the effect of xanthophylls on atherosclerosis is very sparse, whilst indirect clinical evidence was only limited to astaxanthin and lutein. Therefore, well-designed long-term randomized controlled trials (RCTs) are highly recommended for future studies to investigate the effective dose of different xanthophylls on atherosclerosis prevention and their possible ancillary effect in conjunction with drug therapies on different stages of atherosclerosis.</p></div>","PeriodicalId":12406,"journal":{"name":"Food Science and Human Wellness","volume":"13 4","pages":"Pages 1739-1755"},"PeriodicalIF":7.0,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213453024000740/pdfft?md5=311c6ae016b97fb685f37fee48342a05&pid=1-s2.0-S2213453024000740-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134914217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, different promoters (P<sub>aprE</sub>, P<sub>43</sub>, and P<sub>glv</sub>) were compared and applied. The results indicated that the strain RIK1285-pBE-P<sub>glv</sub>-YjcN-<em>LALBA</em> had the highest <em>α</em>-LA yield, reaching 122.04 μg/mL. This study demonstrates successful expression and secretion of human <em>α</em>-LA in <em>B. subtilis</em> and establishes a foundation for simulating breast milk for infant formulas and developing bioengineered milk.</p></div>","PeriodicalId":12406,"journal":{"name":"Food Science and Human Wellness","volume":"13 4","pages":"Pages 2310-2316"},"PeriodicalIF":7.0,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213453024001009/pdfft?md5=853db494638e0339b27b3150996b292a&pid=1-s2.0-S2213453024001009-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134914444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
