However, bovine whey protein contains β-lactoglobulin (β-LG), which is not found in human whey protein, and some α-lactalbumin (α-LA) with a different amino acid sequence, which has the potential to cause allergic reactions. Eating bovine whey protein can cause allergic reactions in the human immune system. This phenomenon refers to an allergy to bovine whey protein. It is estimated that this condition affects 1.9% to 4.9% of infants globally. <em>Lactobacilli</em> possess a robust protein hydrolysis system capable of disrupting epitopes associated with whey protein allergies while yielding hydrolyzed products and bioactive peptides. This process represents a safe and effective approach to reducing the allergenicity of milk. Consequently, we established a mouse model for whey protein allergy and evaluated the effects of fermented whey protein produced by <em>Lactobacillus</em> on allergic symptoms in mice using ELISA, real-time fluorescence quantitative PCR (RT-qPCR), and HE staining techniques. Furthermore, we analyzed the intestinal flora of allergic mice through 16S rDNA sequencing to elucidate the relationship between <em>Lactobacillus</em>-mediated alterations in gut microbiota and allergic phenotypes within this study. The results showed that compared with the whey protein group, the levels of immunoglobulin E (IgE), histamine and mast cell protease in the serum of mice in the lactic acid bacteria fermented whey protein group were significantly increased, and the secretion of T helper 2 (Th2) type cytokines was inhibited, the production of T helper 1 (Th1) type cytokines was promoted, and the inflammation caused by sensitized mice was significantly alleviated. Furthermore, the fermentation of whey protein by <em>Lactobacillus</em> resulted in an improvement in the intestinal flora of mice, accompanied by promotion of the growth of probiotics such as <em>Lactobacillus</em>, <em>Odoribacter</em> and <em>Bacteroides</em>. This effectively alleviated the allergic reaction in mice. The findings of this experiment provide a theoretical basis for the development of hypoallergenic dairy products and offer a certain degree of guidance for the clinical treatment of allergic diseases.</p>","PeriodicalId":77,"journal":{"name":"Food & Function","volume":" 8","pages":" 3152-3165"},"PeriodicalIF":5.1,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, a large number of studies have shown that the imbalance of intestinal flora is one of the important factors in the malignant development of diseases. Therefore, improving organ function by regulating intestinal flora may be an important strategy to prevent the side effects of chemotherapy drugs. Lycopene (LYC) is found in a wide range of red foods and has antioxidant, anti-inflammatory and immune-enhancing effects. So the purpose of this study was to explore its effect on hepatointestinal injury caused by chemotherapy drugs. The results of this study showed that CIS could significantly restore body weight, diet, water intake, and AST, ALT and other physiological and biochemical indexes of rats. HE staining, projective electron microscopy and TUNEL results showed that LYC alleviated morphological and ultrastructural damage of the liver and intestine. Then, ELISA results showed that LYC can reduce cell apoptosis by increasing the antioxidant capacity and reducing inflammatory response. Secondly, 16sRNA and metabolome results showed that LYC enriched beneficial bacteria (Firmicutes and Proteobacteria), reduced harmful bacteria (<em>E. coli</em>, <em>etc</em>.), enhanced metabolic pathway changes such as taurine and hypotaurine metabolism, and alleviated organ damage caused by CIS. Finally, network pharmacology, molecular docking and immunohistochemistry showed that LYC could reduce CIS induced hepatocyte inflammation and apoptosis by activating the PI3K/AKT pathway.

Our previous research demonstrated that maternal genistein (GEN) intervention ameliorated the dysregulation of glucolipid metabolism induced by intrauterine overnutrition in adult offspring, accompanied by changes in the composition of gut microbiota; however, the underlying mechanisms remain unclear. Here, we used a maternal overnutrition model induced by excess energy intake before and throughout pregnancy and lactation, with maternal GEN administered during the same period. The female offspring were raised on a standard chow diet until sacrificed at 24 weeks. The mRNA levels of browning markers were quantified in inguinal subcutaneous adipose tissues, followed by methylation analysis <em>via</em> the MassArray method. Cecal contents were collected for untargeted metabolomic analysis and a target quantitative analysis of methionine cycle metabolites. Spearman correlation analyses were used to assess whether cecal metabolites are involved in the methylation of browning-related genes and influence their expression. The results showed that maternal GEN supplementation reversed the downregulation of browning markers caused by perinatal high-fat diets in adult female offspring, consistent with a reduction in their methylation levels. Subsequently, we also found that maternal GEN consumption altered cecal metabolite profiles in offspring, promoting the production of bile acids, potent regulators of glucolipid metabolism, and reducing metabolites involved in the methionine cycle, key methyl donors for the methylation process. Furthermore, the abundances of these metabolites were significantly correlated with the methylation and expression levels of browning markers. Overall, this discovery suggested that maternal GEN intake decreased the methylation level of browning markers and induced browning in white adipose tissue of offspring, which correlated with alterations in cecal metabolites.

Our previous study has demonstrated that barley protein hydrolysate (BPH) strongly stimulates CCK secretion from EECs <em>in vitro</em>, but the structural characteristics of the responsible components and their underlying mechanism of action have not yet been elucidated. Here, we monitor the plasma levels of CCK in mice after ingestion of BPH to demonstrate its <em>in vivo</em> activity in stimulating CCK secretion. Using size exclusion column chromatography and liquid chromatography-tandem mass spectrometry, we isolate and identify three novel CCK secretion-stimulating peptides, including VQVQIPF, VVTGVGGQ and PQQPQPFFQ. Among them, the peptide VVTGVGGQ exhibits the strongest activity in stimulating CCK secretion. Inhibition experiments show that the calcium-sensing receptor (CaSR) is required for VVTGVGGQ to increase CCK gene transcription and secretion.
