Here, for the first time, we link the traditional use of fish maw heat‑treated with clam shell powder (CPFM) to the restoration of bone‑fat balance. Using INFOGEST simulated digestion followed by LC‑MS/MS analysis, we found that CPFM peptides were predominantly low‑molecular‑weight species (84.6% below 1 kDa), with heptapeptides as the most abundant fraction (20%). In ovariectomized mice, CPFM peptides reduced bone marrow fat accumulation and improved bone microstructure (increased BV/TV and BMD). In bone marrow stromal cells (BMSCs), they concurrently inhibited adipogenic differentiation (reduced Oil Red O‑positive area) and promoted osteogenesis (enhanced ALP activity and mineralization). From CPFM digests, we systematically screened and identified an absorbable tetrapeptide, FLLL, based on its high relative abundance (37.8%), predicted bioactivity (PeptideRanker >0.5), cell‑penetrating ability (CPPpred >0.33), and favorable ADMET properties. In cultured BMSCs, FLLL recapitulated the dual effects of CPFM, promoting osteogenesis while suppressing adipogenesis. Mechanistically, both CPFM and FLLL downregulated adipogenic factors (PPARγ, FABP4, FASN) and upregulated osteogenic markers (RUNX2, COL1α2, BGLAP). Surface plasmon resonance confirmed direct binding of FLLL to RUNX2 (KD = 32.5 μM), and rescue experiments indicated that FLLL regulates the bone‑fat balance in association with the PPARγ/RUNX2 axis. Collectively, this study establishes a chain of evidence spanning peptide profiling, in vivo efficacy, active component identification, and mechanistic insight. These findings support CPFM as a promising dietary candidate and identify FLLL with well-defined in vitro bioactivity.","PeriodicalId":12406,"journal":{"name":"Food Science and Human Wellness","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/FSHW.2026.9251234.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148861302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lactobacilli recognized as natural GABA producers, have garnered significant attention due to their safety and functionality. In our study, we aimed to isolate a high GABA-producing Lactobacillus strain from traditional fermented foods and investigate its growth characteristics, acid-producing capacity, and stress tolerance. Subsequently, a p-chlorophenylalanine (PCPA)-induced insomnia mouse model was established to evaluate the sleep-enhancing effects and underlying mechanisms of the strain's fermentation broth. We isolated six strains of GABA-producing lactic acid bacteria, among which strain XBMU-SN-23 exhibited the highest GABA production (2.150 g/L) as determined by high-performance liquid chromatography (HPLC) and was identified as Lactiplantibacillus plantarum via 16S rDNA sequencing. Treatment with XBMU-SN-23 fermentation broth significantly improved the quiet state of PCPA-induced insomniac mice. It mitigated PCPA-induced damage to hypothalamic neuronal cells, increased the levels of GABA, serotonin (5-HT), interleukin-1 (IL-1), and melatonin (MT), while simultaneously reducing glutamate (Glu) and dopamine (DA) in the serum and hypothalamus of the mice, thereby contributing to the restoration of neurotransmitter balance. Additionally, the treatment led to an increase in the expression of 5-HT1A, GABAARα1, and GABAARγ2 receptor proteins, which play a crucial role in the regulation of molecular pathways and collectively enhance sleep quality. These findings support the sedative-hypnotic benefits of XBMU-SN-23 fermentation broth and provide a theoretical foundation for the future development of functional GABA-producing probiotic products.","PeriodicalId":12406,"journal":{"name":"Food Science and Human Wellness","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/FSHW.2026.9251168.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148672229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2002, it was officially approved by China’s Ministry of Health as a medicinal herb permitted for use in health food products. Baohuoside I (BHS), a characteristic component of Epimedii Folium, exhibits a broad spectrum of anti-cancer activities. This study aims to explore the therapeutic effects and underlying mechanistic basis of BHS against triple-negative breast cancer (TNBC) using integrated pharmacological and bioinformatics approaches. In vitro experiments demonstrated that BHS dose-dependently inhibited TNBC cell viability (IC50: MDA-MB-468 = 20.02 ± 3.46 µM; MDA-MB-231 = 41.76 ± 1.77 µM), with also significant suppressing cell proliferation and migration (P < 0.05). In vivo, BHS exhibited a favorable safety profile in both healthy and TNBC xenograft model mice (P > 0.05), and also effectively suppressed TNBC xenograft growth (P < 0.05). Transcriptomic analysis combined with machine learning-based bioinformatic analysis identified ten core cell cycle regulatory genes (MCM2, MCM3, MCM5, EXO1, PARP1, CDC45, POLE2, RFC3, PCNA, and CCNE2), whose expression was substantially downregulated by BHS, as validated through molecular biological assays. Cellular thermal shift assay and drug affinity responsive target stability assay identified PMS2 as a putative direct binding target of BHS, with molecular docking validating a high-affinity interaction (binding energy: -8 kcal/mol). Collectively, these results support BHS as a promising safe and effective therapeutic candidate for TNBC, with its anti-tumor activity predominantly associated with the regulation of cell cycle progression.","PeriodicalId":12406,"journal":{"name":"Food Science and Human Wellness","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/FSHW.2026.9251152.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148672230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, it has been found that fucoidan (FC) has anti-HUA effect, but the mechanism is still lack of systematic research. The aim of this study was to investigate the mechanism of FC on HUA through UA metabolism and intestinal homeostasis. Based on PMP-derived ultra performance liquid chromatography analysis, FC was identified as a sulfated polysaccharide composed of galactose, mannose, trace amounts of mannuronic acid, and xylose. The HUA mouse model was induced by a high-purine diet and potassium oxonate. We found that FC significantly ameliorated renal inflammation and injury and reduce serum UA level in HUA mice. Furthermore, FC intervention modulated UA metabolism by regulating purine metabolic enzyme activity and the expression of UA transporters in the kidney and intestine. It also protected the intestinal tract from damage by upregulating the expression of gut barrier-associated genes, including ZO-1, Claudin, Occludin, and MUC2. 16S rRNA sequencing and targeted metabolomics analysis further revealed that FC administration altered the composition of the gut microbiota, increasing the abundance of beneficial bacteria such as Muribaculum, Alloprevotella, Clostridia_UCG-014, and Rikenella, while decreasing the abundance of harmful bacteria such as Parabacteroides, Enterorhabdus, and Muribaculaceae. Meanwhile, FC reversed the reduction in short-chain fatty acid levels caused by HUA. In sum, FC is a natural UA-lowering active substance with multiple targets and pathways. This study provides new evidence supporting the potential of FC as a dietary supplement for patients with HUA.","PeriodicalId":12406,"journal":{"name":"Food Science and Human Wellness","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/FSHW.2026.9250990.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148401715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In CTX-induced mice, oral Lp2 concurrently activated the TLR2/NF-κB/NLRP3 and Nrf2/HO-1 signaling pathways in the spleen, thereby enhancing the levels of cytokines (IL-2, IL-6, IL-1β, TNF-α, and IFN-γ) and the activity of antioxidant enzymes (CAT, SOD, and GSH), protecting splenic architecture and function. Intestinal NLRP3 inflammasome activation by Lp2 modulated similar cytokine profiles (IL-2, IL-6, IL-1β, TNF-α, IFN-γ), demonstrating its gut- immunoregulatory capacity in CTX-induced mice. Furthermore, Lp2 enhanced short-chain fatty acid (SCFA) metabolism and intestinal barrier by modulating the gut microbiota composition through specific bacterial populations, including Clostridium, Duncaniella, Alistipes, Muribaculum, among others, thereby sustaining intestinal physiological homeostasis.

The recognition mechanism between the aptamer and FQs were studied by the combination of computer-aided molecular simulation and experimental verifications. It was revealed that hydrophobicity of FQs critically governs aptamer-target interactions. Guided by these insights, the original sequence was truncated to a 40-nt aptamer, named as W-G1, which preserved key binding sites and structural stability. W-G1 with the characteristic G-quadruplex (G4) conformation demonstrated excellent affinity and stability for FQs.
