The tumor necrosis factor-alpha (TNF-α) plays a crucial role in the central mechanism of photoaging. TNF-α production leads to direct damage to skin cells and facilitates the degradation of vital extracellular matrix (ECM) proteins. TNF-α stimulates matrix metalloproteinase-1 (MMP-1) activation This accelerates the loss of skin elasticity and wrinkle formation. Thus, preventing photoaging and delaying the skin aging process are important research objectives, and the development of new anti-aging substances that target the TNF-α and MMP-1 pathways is promising. In this context, the efficacies of four extracts derived from two types of <i>Cephalotaxus harringtonia</i> (CH) buds (CH-10Y-buds, CH-200Y-buds) and leaves (CH-10Y-leaves, CH-200Y-leaves) were investigated, exhibiting a significant reduction in reactive oxygen species (ROS). Among the four extracts, CH-10Y-buds was the most effective in reducing ROS and exhibited the highest amounts of harringtonine and homoharringtonine. The activities of harringtonine, homoharringtonine, and ginkgetin were evaluated; harringtonine exhibited a high efficacy in inhibiting TNF-α-induced inflammatory responses and MMP-1 activation, thereby reducing collagen degradation. These findings suggest that CH-10Y-buds and their components herringtonin are promising candidates for preventing damage caused by photoaging. Our results can facilitate the development of new methods for maintaining skin health and inhibiting the skin aging process. Further research is necessary to comprehensively evaluate the potential efficacy of these candidate substances and investigate their applicability to actual skin. Such studies will aid in the development of more effective anti-aging strategies in the future.</p></div>","PeriodicalId":467,"journal":{"name":"Applied Biological Chemistry","volume":"67 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://applbiolchem.springeropen.com/counter/pdf/10.1186/s13765-024-00951-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142596086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Used extensively in industrial and agricultural sectors, TCBs are prevalent pollutants in various ecosystems, including air, food, surface water, groundwater, sediment, soil, and sewage. This is a concern because of their tendency to accumulate in lipid-containing tissues of animals and humans and potentially serious risks to human health and ecosystems.

In Dexa-induced myotube atrophy, treatment with LELJ increased myotube diameter, decreased the expression of muscle atrophy markers, and increased the expression of myosin heavy chain (MHC) isoforms. Supplementation with LELJ improved muscle function and performance in mice with Dexa-induced muscle atrophy as demonstrated by grip strength and running tests. Additionally, it increased skeletal muscle mass, size, and expression of MHC isoforms and protein synthesis-related markers. Furthermore, it reduced the upregulated protein levels of skeletal muscle atrophy markers in Dexa-treated mice. Supplementation with LELJ reversed Dexa-induced translocation of the glucocorticoid receptor and forkhead box O3 from the cytosol to the nucleus in skeletal muscles. LELJ also ameliorated age-related muscle loss by extending lifespan and increasing locomotor capacity in <i>Caenorhabditis elegans</i>.

Treatment of human gingival fibroblasts with GLSO resulted in a significant reduction in the expression of inflammatory factors, including matrix metalloproteinase (MMP)-1 and interleukin (IL)-8, upregulated by lipopolysaccharide or IL-1β. Molecular mechanism studies revealed that the observed decrease in inflammatory factor expression may be attributed to the inhibition of phosphorylated c-Jun N-terminal kinase activity by GLSO. Furthermore, intraperitoneal injection of GLSO in a ligature-induced PD mouse model led to a notable reduction in periodontal inflammation and alveolar bone loss, accompanied by decreased levels of MMP-1 and IL-8. These in vivo results support the potential therapeutic efficacy of GLSO in alleviating PD symptoms. Overall, our study provides novel insights into the beneficial effects of GLSO in PD management.
