Enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of LicoA was developed using a constructed antibody. The assay validation results were highly specific for the target compound, but minimally cross-reactive with the structure-related substances. After optimal conditions, the detection limit was 4.32 ng/mL and the quantification limit was 6.84–107.21 ng/mL. As a result, the developed ELISA was applied to determine the concentration of LicoA in raw licorice and marketed samples. This assay will aid in the quality control of licorice and derived products, as it can be used to identify plant species and determine bioactive markers.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":"33 1","pages":"220 - 234"},"PeriodicalIF":3.0,"publicationDate":"2022-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41451072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accumulated evidence has shown the association between As exposure and elevated risk of the development of coronary heart disease (CHD). Calycosin, a beneficial flavonoid, has demonstrated cardioprotective activities, including those against CHD, in preclinical studies. The anti-As-related CHD activity and mechanism of calycosin have not yet been elucidated. Here, we aimed to determine the core biotargets and molecular mechanisms of calycosin against As-interrelated CHD via integrated bioinformatic analysis, including network pharmacology and molecular docking. The network pharmacology data demonstrated 41 intersection genes of calycosin against As-related CHD, prior to the identification of 15 core targets. Additional in silico investigation indicated that mitogen-activated protein kinase-3 (MAPK3), epidermal growth factor receptor (EGFR), and interleukin-6 (IL6) were the primary pharmacological targets of calycosin for the treatment of As-related CHD. In addition, the therapeutic effects can be realized via cardioprotection-associated signaling pathways for reducing As-induced myocardial toxicity and impairment and boosting CHD functional reparation. In summary, calycosin mediates potent pharmacological effects in As-related CHD therapy functioning via multiple targets and multiple pathways. The results may eventually aid in promoting future clinical application after experimental verification.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":"33 1","pages":"207 - 219"},"PeriodicalIF":3.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44853032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed: (1) Compared to wheat bran group, the contents of crude protein, trichloroacetic acid-soluble protein, dietary fibre (DF), mannan and total polyphenols in wheat bran were increased by solid state fermentation. (2) Compared to the control group, fermented wheat bran increased the levels of serum biochemical parameters, reproductive hormones, immunoglobulins and anti-inflammatory factors.

Recombinant MBP-Eno was reactive with blood serum specimens of fish-allergic patients, confirming that β-enolase is a newly identified allergen of common carp. Two monoclonal antibodies (MAbs) against recombinant β-enolase were generated that showed cross-reactivity with β-enolases of other organisms. Both antibodies recognized β-enolases from other fish species extracts, while MAb 6E4 showed a broad reactivity with pork, chicken, yeast, and E. coli samples. Epitope mapping using MBP-Eno variants revealed that β-enolase region comprising amino acids 623–698 presumably includes MAb 6E4 epitope.

Thus, in this study, we investigated whether Kadsura japonica fruits (KJF) exhibits immunostimulatory activity and anti-obesity activity. KJF increased the production of immunostimulatory factors and phagocytosis in RAW264.7 cells. Inhibition of TLR2 and TLR4 blocked KJF-mediated production of immunostimulatory factors in RAW264.7 cells. In addition, the inhibition of MAPK and PI3 K/AKT signaling pathway reduced KJF-mediated production of immunostimulatory factors, and the activation of MAPK and PI3 K/AKT signaling pathway by KJF suppressed the inhibition of TLR2/4. KJF attenuated the lipid accumulation and the protein expression such as CEBPα, PPARγ, perilipin-1, adiponectin, and FABP4 related to the lipid accumulation in 3T3-L1 cells. In addition, KJF inhibited excessive proliferation of 3T3-L1 cells and protein expressions such as β-catenin and cyclin D1 related to cell growth. These findings indicate that KJF may have immunostimulatory activity and anti-obesity activity.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":"33 1","pages":"65 - 79"},"PeriodicalIF":3.0,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42754091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the detection of arecoline is mostly dependent on chromatography-based approaches, which are time-consuming and expensive. We used arecaidine as a hapten to produce a highly specific monoclonal antibody (mAb) against arecoline. An indirect competitive enzyme-linked immunosorbent assay (icELISA) was developed using the mAb-A5H12, to detect arecoline in traditional Chinese medicines and fresh areca nuts. The icELISA indicated that the half maximum inhibition concentration (IC50) for arecoline was 67.9 ng/mL, with a working range of 10.1–502.6 ng/mL and a limit of detection (LOD) of 3.6 ng/mL. High-performance liquid chromatographic (HPLC) confirmed the accuracy and the working range of icELISA, suggesting that the icELISA approach based on the arecoline specific antibody could be a widely applicable and easy operation method in detection of arecoline in foods and medicines.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":"33 1","pages":"113 - 126"},"PeriodicalIF":3.0,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44219607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
