A promising strategy for assessing the uricosuric effect of anti-hyperuricemia candidates: a case study of caffeoylquinic acids extract of Artemisia selengensis Turcz. leaves

Food, Nutrition and Health 2025年第1期2卷 1-12页

作者： Xiang, Lin Mansour, Mohammed Huang, Yuting Wu, Ting Pan, Siyi Xu, Xiaoyun College of Food Science and Technology Huazhong Agricultural University Wuhan China Hubei Key Laboratory of Fruit & Vegetable Processing & Quality Control Huazhong Agricultural University Wuhan China Key Laboratory of Environment Correlative Dietology (Ministry of Education) Huazhong Agricultural University Wuhan China National Key Laboratory for Germplasm Innovation & Utilization of Horticultural Crops Huazhong Agricultural University Wuhan China

Caffeoylquinic acids (CQAs) are phenolic acids found in various plants that possess multiple biological activities including anti-oxidation, anti-inflammation, and xanthine oxidase inhibitory activity. Our previous research demonstrated that CQAs-rich Artemisia selengensis Turcz. leaves extract (ASTLE) effectively lowered uric acid levels in hyperuricemia mice. However, further evidence is needed to elucidate the mechanism of the uric acid-lowering effect of ASTLE. In this study, a sensitive but non-radioactive in vitro method based on 6-carboxyfluorescein (6-CFL) was established, validated, and further applied to assess the uricosuric potential of ASTLE. Furthermore, molecular docking, qRT-PCR, and western blot were employed to evidence the uricosuric effect of ASTLE. The results demonstrated that ASTLE exhibited the potential to inhibit uric acid reabsorption, manifested as the inhibition of 6-CFL uptake by human kidney 2 (HK-2) cells (IC50 = 533.67 ± 19.91 µg/mL), and CQAs were identified as its dominant bioactive compounds. Mechanism investigation further revealed that the uptake inhibitory effect of ASTLE was attributed to the hydrogen bonding interactions of CQAs, particularly di-CQAs, with uric acid transporters URAT1 and GLUT9, as well as to the down-regulation of mRNA and protein expression of URAT1 and GLUT9 and the up-regulation of mRNA and protein expression of ABCG2 by ASTLE. This study indicated that ASTLE has potent uricosuric effect. Moreover, this study suggested that the combination of 6-CFL uptake inhibition assessment, molecular docking, qRT-PCR, and western blot analysis could be a promising strategy for revealing the role of anti-hyperuricemia candidates in promoting uric acid excretion.

The Metal Tolerance Protein (MTP) family members play a crucial role in the transport and tolerance of divalent metal cations. However, a comprehensive study of MTP genes in Brassica juncea and their expression patterns under heavy metal (HM) exposure remains unclear. In this study, we identified 33 BjMTP genes through the HMMER program (Cation_efflux;PF01545) and BLAST analysis. Subsequently, these 33 BjMTP members were subjected to a series of bioinformatics methods, including physicochemical properties, phylogenetic tree, conserved motifs, protein structures, collinearity, spatiotemporal expression patterns by RNA-seq data, GO enrichment, and expression profilings under six HM stresses. As a result, the BjMTP genes were classified into three subgroups (Zn-CDF, Zn/Fe-CDF, and Mn-CDF) and seven branches (G1, G4, G5, G6, G7, G8, and G12). We also successfully identified specific genes and crucial expression modules within the BjMTP family genes that respond to various HM stresses. Notably, ***4 and ***5 exhibited strong responses to all six HM inductions, suggesting their vital role in facilitating plant tolerance to HM stresses. These findings provide excellent gene resources for the genetic improvement of HM-tolerant rapeseed and the remediation of HM-contaminated soils. © 2024, The Authors. All rights reserved.

Cadmium (Cd), a toxic heavy metal, adversely affects the physiological functions of organisms, garnering global concern due to widespread Cd pollution. In this study, Bacillus coagulans LBK which was isolated from silage feed exhibited robust Cd tolerance and adsorption capabilities, with tolerance exceeding Cd concentrations of 1000 mg/L. The strain also possesses a significant scavenging effect on DPPH and hydroxyl radicals, with a clearance rate of approximately 40%. In vivo, LBK significantly reduced the mortality of mice and increased the levels of SOD and CAT in the liver. In addition, the strain reduced the Cd toxicity of mice exposed to Cd and restored their liver damage. The results of 16S showed that B. coagulans LBK significantly changed the structure of intestinal microbiota. LBK also increased the abundance of beneficial bacteria, such as Leptospirillaceae and Lactobacillus. Metabolomics analysis showed that LBK could regulate metabolic disorders caused by Cd exposure and restore the levels of amino acids such as glutamic acid, leucine, and aspartic acid. Based on the above advantages, B. coagulans LBK may be considered a promising candidate for alleviating oxidative stress caused by acute Cd exposure. © 2024, The Authors. All rights reserved.

Assessments of inventory incompleteness often focus on terrestrial taxonomic groups, with less attention given to freshwater ecosystem groups. In this study, we constructed a wetland plant database for the Qinghai-Tibet Plateau (QTP) and evaluated the inventory incompleteness of wetland plants. By combining three types of variables: safety, attractiveness, and accessibility, we identified the key drivers of inventory incompleteness and established priority areas for further investigation. The results showed that the inventory incompleteness of wetland plants on the QTP is relatively low, and the areas with incomplete inventories are mainly concentrated in the Himalayas and Hengduan Mountains. Safety variables emerged as the most important factors influencing inventory incompleteness, with landslide risk, slope, species richness, and livestock density identified as key variables affecting this incompleteness. We identified the southeastern Hengduan Mountains as a priority area for future wetland plant surveys. Specifically, the priority areas for future wetland plant collection are mainly distributed in the Qomolangma Region, the middle reaches of the Yarlung Zangbo River, the Nyenchen Tanglha Mountains-Eastern Himalayas, the transition zone between the Northern Tibetan Plateau and the Hengduan Mountains, and the Qionglai Mountains-Daxue Mountains-Shaluli Mountains. This study provides valuable references for future wetland plant sampling and conservation efforts on the QTP.

The levels of metabolites in honey influenced by floral origin, production region, and bee species. However, environmental factors how affected the honey quality was remained unclear. Here, we analyzed 3596 metabolites in 36 honey samples from Yunnan and 15 from Shennongjia using untargeted metabolomics. Comparative analysis showed that geniposidic acid, kynurenic acid and caffieine accumulated at significantly different levels between Shennongjia and Yunnan honey. Furthermore, 36 Yunnan honey were divided into two distinct groups by altitude, about 1700 m. Notably, quercetin, hyperoside, taxifolin, rutin, tryptophan, astragalin and phenylalanine were higher levels in high-altitude honey (>1700 m), whereas abscisic acid was higher levels in low-altitude honey (≤1700 m). Among these eight metabolites, hyperoside, astragalin, taxifolin, and tryptophan also showed significant different between high- and low- altitude honey in Shennongjia. Our findings highlight the effect of altitude on honey health-promoting components, providing valuable insights into honey quality. © 2024, The Authors. All rights reserved.

Biological in-process dressing (BID) is a new dressing technology based on the catalytic oxidation of microorganisms. This study applied BID to address the issue of fixed abrasive pad (FAP) loading and glazing during sapphire wafer lapping. Diamond FAPs with pure iron powder as a binder were sintered via hot-press sintering. A dual-chamber circulating biological dressing device was designed to continuously spray supernatant (cyclically regenerated by bacterial activity) onto the pad surface during lapping, enabling in-process dressing. The experimental results demonstrate that BID technology significantly enhances the material removal rate ( MRR ) of sapphire, achieving in a 13.4-fold improvement over non-dressing conditions. Moreover, the three-dimensional surface roughness ( S a ) of sapphire rapidly decreased from 403.5 nm to 107.3 nm within 10 min. The key to sustaining stable dressing efficiency lies in balancing Fe 3+ depletion through oxidation of the pure iron binder with Fe 3+ regeneration via microbially driven Fe 2+ oxidation. This research demonstrates that BID technology effectively improves the lapping efficiency and surface quality for difficult-to-machine materials while offering environmental benefits, providing new insights for fixed abrasive processing technologies.
