BMC Genomics 2024; 25:561. [PMID: 38840044 PMCID: PMC11151499 DOI: 10.1186/s12864-024-10455-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 05/24/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND Artemisia selengensis, classified within the genus Artemisia of the Asteraceae family, is a perennial herb recognized for its dual utility in culinary and medicinal domains. There are few studies on the chloroplast genome of A. selengensis, and the phylogeographic classification is vague, which makes phylogenetic analysis and evolutionary studies very difficult. RESULTS The chloroplast genomes of 10 A. selengensis in this study were highly conserved in terms of gene content, gene order, and gene intron number. The genome lengths ranged from 151,148 to 151,257 bp and were typical of a quadripartite structure with a total GC content of approximately 37.5%. The chloroplast genomes of all species encode 133 genes, including 88 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Due to the contraction and expansion of the inverted repeats (IR), the overlap of ycf1 and ndhF genes occurred at the inverted repeats B (IRB) and short single copy sequence (SSC) boundaries. According to a codon use study, the frequent base in the chloroplast genome of A. selengensis' third codon position was A/T. The number of SSR repeats was 42-44, most of which were single nucleotide A/T repeats. Sequence alignment analysis of the chloroplast genome showed that variable regions were mainly distributed in single copy regions, nucleotide diversity values of 0 to 0.009 were calculated by sliding window analysis, 8 mutation hotspot regions were detected, and coding regions were more conserved than non-coding regions. Analysis of non-synonymous substitution (Ka) and synonymous substitution (Ks) revealed that accD, rps12, petB, and atpF genes were affected by positive selection and no genes were affected by neutral selection. Based on the findings of the phylogenetic analysis, Artemisia selengensis was sister to the genus Artemisia Chrysanthemum and formed a monophyletic group with other Artemisia genera. CONCLUSIONS In this research, the present study systematically compared the chloroplast genomic features of A. selengensis and provided important information for the study of the chloroplast genome of A. selengensis and the evolutionary relationships among Asteraceae species.

Lian Y, Fu G, Liang X, He X, Xu J, Fan H, Wan Y. Combination of Artemisia selengensis Turcz leaves polysaccharides and dicaffeoylquinic acids could be a potential inhibitor for hyperuricemia. Int J Biol Macromol 2024; 271:132687. [PMID: 38806079 DOI: 10.1016/j.ijbiomac.2024.132687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 05/23/2024] [Accepted: 05/25/2024] [Indexed: 05/30/2024]
Abstract
Caffeioyl quinic acids and polysaccharides from Artemisia selengensis Turcz are considered potential bioactive substances for hyperuricemia (HUA) treatment. While the mechanism of multi-component combined intervention of polysaccharides and dicaffeoylquinic acids (diCQAs) is not yet clear. In this study, we investigated the effect of A. selengensis Turcz leaves polysaccharides (APS) on the HUA treatment with diCQAs in vitro by direct inhibition of XOD activities and in vivo by using animal model. The results showed that APS had almost no inhibitory effect on XOD activities in vitro, but the inhibitory activity of diCQAs on XOD was affected by changes in inhibition type and inhibition constant. Compared to APS and diCQAs alone, high-dose APS and diCQAs in combination (ADPSh) could significantly reduce the production of uric acid (16.38 % reduction compared to diCQAs group) and oxidative stress damage. Additionally, this combined therapy showed promise in restoring the gut microbiota balance and increasing the short-chain fatty acids levels. The results suggested that APS and diCQAs in combination could be a potential inhibitor for HUA treatment.

Biomed Pharmacother 2024; 173:116368. [PMID: 38471269 DOI: 10.1016/j.biopha.2024.116368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 02/17/2024] [Accepted: 02/28/2024] [Indexed: 03/14/2024] Open
Abstract
Paeonol, as one of the most abundant plant-derived polyphenols, has multiple bioactivities including anti-inflammatory, anti-tumor, and anti-cardiovascular diseases. Nevertheless, the anti-aging effects and related mechanisms of paeonol are rarely reported. In this study, we found that paeonol significantly prolonged the mean lifespan of Caenorhabditis elegans (C. elegans) by 28.49% at a dose of 200 μM. Moreover, paeonol promoted the health of C. elegans by increasing the body bending and pharyngeal pumping rates and reducing the lipofuscin accumulation level. Meanwhile, paeonol induced the expression of stress-related genes or proteins by activating the transcription factors DAF-16/FOXO, SKN-1/Nrf2, and HSF-1, which in turn enhanced oxidative and thermal stress tolerance. The mechanism behind the anti-aging effect of paeonol occurred by down-regulating the insulin/IGF-1 signaling (IIS) pathway. Our findings shed new light on the application of paeonol for longevity promotion and human health.

Abstract
Mulberry pomace is rich in phytochemicals, but there are few studies on its utilization as a by-product. Natural foods containing phytochemicals can alleviate the toxic effects of excessive glucose intake. In this study, we investigated the protective effect of Lactobacillus plantarum-fermented mulberry pomace extract (FMPE) under hyperglycemic conditions. The phenolic compounds and α-glucosidase inhibition of FMPE were determined using UPLC-MS and chemical models. Furthermore, Caenorhabditis elegans was a model system to study the hypoglycemic effects. The results showed that the polyphenolics and α-glucosidase inhibition were improved during fermentation. Three phenolic components (cyanidin, 2,4,6-trihydroxybenzaldehyde, and taxifolin) were important variables for α-glucosidase inhibition. FMPE and the three key compound treatments reduced the glucose content and reactive oxygen species (ROS) level in Caenorhabditis elegans. The protective mechanism occurred by activating DAF-16/FOXO and SKN-1/Nrf2. This study suggests that Lactobacillus plantarum-fermentation was a potential way to utilize mulberry pomace polyphenols as hypoglycemic food ingredients.

Abstract
Numerous studies reported that betulinic acid (BA), a natural product extracted from birch bark, exhibited various beneficial effects in vitro. However, its pharmacological activities in aging are rarely understood. In this study, Caenorhabditis elegans was deployed as a whole animal model to investigate the impacts of BA on lifespan and stress resistance. Wild-type C. elegans were fed in the presence or absence of BA and tested for a series of phenotypes, including longevity, mobility, reproductive capacity, pharyngeal pumping, heat stress, and oxidative stress. BA at the optimal dose (50 μg/mL) extended the lifespan, improved the healthspan, and significantly evoked the increased oxidative stress resistance in C. elegans. Incorporating the genetic analysis with different types of longevity mutants, DAF-16, the downstream effector of the Insulin/IGF-1 receptor signaling, was revealed to mediate the protective effects of BA on lifespan and antioxidant activity. Together, these data showcased the potential of BA in promoting healthy aging, which shall facilitate its further development in the food and pharmaceutical industries.
