Therefore, the present study aimed to explore the functional properties of Cannabis sativa stem‑derived nanoparticles (CSS‑NPs) and evaluate their potential as a cosmetic ingredient. Using nanoparticle analysis, CSS‑NPs, with a mean diameter of ~120 nm exhibited notable resistance to external stress conditions, including pH fluctuation and enzymatic degradation by DNase, RNase and proteinase K. They also contained 48 distinct biochemical components. <i>In vitro</i> assays revealed that CSS‑NPs significantly downregulated the expression of genes and proteins associated with melanin synthesis in mouse B16F10 melanoma cells under α‑melanocyte stimulating hormone (α‑MSH)‑induced hyperpigmentation. These inhibitory effects were mediated by the activation of ERK and Akt signaling pathways. Furthermore, CSS‑NPs improved the viability of α‑MSH‑treated B16F10 cells; this was accompanied by the upregulation of antioxidant‑associated enzymes and a decrease in α‑MSH‑induced reactive oxygen species levels. Collectively, these findings suggested that CSS‑NPs carry out a key role in mitigating skin pigmentation and enhancing antioxidant defenses by modulating the ERK/Akt axis during excessive melanin synthesis. Thus, CSS‑NPs represent a promising multifunctional cosmetic ingredient with potential in treating pigmentation disorders and protecting skin cells.</p>","PeriodicalId":18818,"journal":{"name":"Molecular medicine reports","volume":"31 6","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study delved into the therapeutic potential and underlying mechanisms of AKG in ameliorating septic cardiomyopathy. A mouse model of sepsis was generated and treated with AKG via the drinking water. Cardiac function was assessed using echocardiography, while the mitochondrial ultrastructure was examined using transmission electron microscopy. Additionally, in vitro, rat neonatal ventricular myocytes were treated with lipopolysaccharide (LPS) as a model of sepsis and then treated with AKG. Mitochondrial function was evaluated via ATP production and Seahorse assays. Additionally, the levels of reactive oxygen species were determined using dihydroethidium and chloromethyl derivative CM‑H2DCFDA staining, apoptosis was assessed using a TUNEL assay, and the expression levels of mitochondria‑associated proteins were analyzed by western blotting. Mice subjected to LPS treatment exhibited compromised cardiac function, reflected by elevated levels of atrial natriuretic peptide, B‑type natriuretic peptide and β‑myosin heavy chain. These mice also exhibited pronounced mitochondrial morphological disruptions and dysfunction in myocardial tissues; treatment with AKG ameliorated these changes. AKG restored cardiac function, reduced mitochondrial damage and corrected mitochondrial dysfunction. This was achieved primarily through increasing mitophagy and mitochondrial fission. <i>In vitro</i>, AKG reversed LPS‑induced cardiomyocyte apoptosis and dysregulation of mitochondrial energy metabolism by increasing mitophagy and fission.
