To investigate the effects of ginseng soluble dietary fiber (GSDF) on the spermatogenic potential in high-fat diet (HFD)-induced obese mice. <i>Method</i>. C57BL/6 mice were fed an HFD for 60 days, and GSDF was administered by gastric gavage. The mice were divided into control, HFD, GSDF (high, medium, and low), and positive (metformin and MH) groups. During this period, changes in body weight were recorded. Various organ indices were measured 24 h after the last dose. Sperm quality in the vas deferens and epididymis tail was determined using fully automated analyzers. Serum levels of the three lipids, cytokines, and hormones were detected by ELISA. Pathological changes in the testicular tissue and epididymal fat were observed by H&amp;E and immunofluorescence staining of the testicular tissue for superoxide dismutase (SOD) and 4-hydroxynonenal (4-HNE). Changes in the levels of MAPK pathway proteins in the testicular cells were detected by western blotting. <i>Result</i>. GSDF intervention significantly reduced the body weight, renal index, and white fat in obese mice, while increasing the testicular organ index. GSDF intervention significantly reduced serum total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) levels in mice compared to the HFD group, thereby improving hyperlipidemia. Simultaneously, the serum cytokine IL-4 level was increased, IL-6 level was significantly reduced, testosterone (T) hormone level was significantly increased, and follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were significantly reduced in the GSDF-treated mice. The viability, survival rate, and density of spermatozoa in the treated groups significantly improved. Testicular interstitial cell vacuolization and collagen fibrosis improved, spermatogonia were aligned, and epididymal fat cell hypertrophy and vacuolization were suppressed. In the GSDF treatment group, SOD levels increased significantly, whereas 4-HNE levels decreased, with the most evident effect observed in the medium-dose group. GSDF ameliorated metabolic disorders in obese mice by regulating the p-JNK/p-p38MAPK pathway. <i>Conclusion</i>. GSDF ameliorated spermatogenic potential in obese mice by regulating the MAPK signaling pathway. Thus, GSDF may be an effective lipid-lowering agent for improving the reproductive potential of obese mice.</p>\u0000 </div>","PeriodicalId":15802,"journal":{"name":"Journal of Food Biochemistry","volume":"2024 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/6235198","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141973648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to investigate the variations in nutritional quality of goji berries across different harvest stages by utilizing widely targeted metabolome and transcriptome. The results showed that goji berries of the first harvest stage had advantages in terms of size and metabolic levels, and there was little difference in sugars and organic acids levels. Within significantly enriched phenylpropanoid and flavonoid pathways, chlorogenic acid, and its positional isomers (neochlorogenic acid and cryptochlorogenic acid) increased significantly along with P-coumaroyl quinic acid as the harvest stages progressed, while the other bioactive DEMs including scopoletin, scopolin, naringenin, and pruning exhibited a decreasing trend. The key DEGs encoding PAL, HCT, 4CL, C4H, TOGT1, and C12RT1 were suggested to regulate the variations of these DEMs. Furthermore, six oxidative metabolites enriched in alpha-linolenic acid and linoleic acid metabolism pathways all peaked at the second harvest stage. Climate or plant weakening is suggested as potential factors influencing the metabolic and transcriptomic changes in goji berries.

We observed that FA greatly decreased BC cell viability without any obvious inhibitory effects on normal cell viability. Further, FA could significantly lead to the apoptosis of MDA-MB-231 cells. FA administration dramatically increased the levels of reactive oxygen species (ROS) in MDA-MB-231 cells, and mitochondria-dependent apoptosis occurred via the MAPK/STAT3/NF-<i>κ</i>B pathways. It was also demonstrated that with an increase in FA treatment time, the G2/M phase ratio increased and the expression of p-AKT and cycle-related proteins was inhibited. The migration of MDA-MB-231 cells was significantly inhibited after FA treatment. FA reduced N-cadherin, vimentin, and SNAI 1 expression levels through the MAPK signaling pathway. Pretreatment with N-acetylcysteine and MAPK inhibitors (SP600125 or SB203580) increased the expression of these proteins, whereas pretreatment with the MAPK inhibitor (FR180204) decreased their expression. In conclusion, FA can increase ROS levels, induce mitochondria-dependent apoptosis, block the G2/M phase cycle, and inhibit cell migration.

To demonstrate the potential harmfulness of these substances, 28 samples of commercially available würstels of different suppliers, price category, package size, and produced with mechanically separated chicken and turkey meat were randomly collected from the Italian market. The presence of antibiotics was assessed by LC/HRMS; bone fragments were identified using histological, histochemical, and microscopical analyses; the cytotoxic and proinflammatory activity of the würstels and their ingredients was assessed using ELISA.
