Bone metastatic human breast cancer MDA-MB-231 cells are triple negative. The novel marine factor 3,5-dihydroxy-4-methoxybenzyl alcohol (DHMBA), a potent antioxidant, has been shown to prevent oxidative stress by scavenging free radicals in cells. This study investigates the effects of DHMBA on MDA-MB-231 cells in vitro. MDA-MB-231 cells were cultured with DHMBA (0.1–100 μM). DHMBA blocked the growth and stimulated the death of MDA-MB-231 cells, resulting in reduced cell numbers. DHMBA treatment decreased PI3-kinase 100α, Akt, MAPK, phosphor-MAPK, and mTOR and increased p53, p21, and Rb, which are suppressors in cell growth. DHMBA inhibited metastatic activity, including adhesion and migration of MDA-MB-231 cells. Coculture with MDA-MB-231 cells resulted in decreased growth and stimulated death of osteoblastic MC3T3-E1 cells and macrophage RAW264.7 cells, suggesting that cancer cells affect the bone microenvironment. Production of TNF-α, which is the mediator in the bone microenvironment, in MDA-MB-231 cells was inhibited by DHMBA treatment. Crosstalk between cancer cells and cells in the bone microenvironment was blocked by culture with DHMBA. DHMBA may inhibit the activity of triple-negative human breast cancer cells, providing a useful tool for the treatment of breast cancer.</p>\u0000 </div>","PeriodicalId":143,"journal":{"name":"Chemical Biology & Drug Design","volume":"105 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effect of resveratrol on chronic rhinosinusitis (CRS) still lacks systematic research. This study aims to elucidate the potential mechanism of resveratrol against CRS disease through network pharmacology and further verify it through biological experiments in human nasal epithelial cells (HNEpCs). The potential targets and pathways of RES against CRS disease were predicted by network pharmacology and molecular docking. Furthermore, the inflammation of HNEpCs was induced by lipopolysaccharide (LPS). The method of ELISA was used to detect changes in inflammatory factors and oxidative stress-related factors. The RT-qPCR method was adopted to analyze the changes of genes in related signaling pathways. As a result, 33 potential targets related to the effect of RES against CRS disease were obtained. According to the results of network pharmacology, it was shown that the effect of RES against CRS disease was closely related to the inflammation, oxidative stress, and apoptosis. A variety of results from cell experiments verified that RES can effectively inhibit the inflammation, oxidative stress and apoptosis of LPS-induced HNEpCs. Together, the present study systematically clarified the possible mechanisms of RES in the treatment of CRS and provided new ideas for the drug research of this disease.</p>\u0000 </div>","PeriodicalId":143,"journal":{"name":"Chemical Biology & Drug Design","volume":"105 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the specific antitumor mechanisms of RUT in NSCLC remain unclear. This study demonstrates that RUT induces apoptosis and significantly reduces the viability of NSCLC cell lines. This effect is achieved by stimulating intracellular ROS production, leading to mitochondrial dysfunction. The decreased cell viability observed with RUT treatment is attributed to the elimination of ROS and apoptosis through the suppression of ROS by N-acetylcysteine (NAC). Furthermore, RUT therapy elevated the production of CXCL10 and CCL5 in NSCLC cell lines and markedly activated the STING pathway in NSCLC cells. Mechanistically, RUT substantially decreased the levels of PD-L1 protein in NSCLC cells.

The data showed that STA improved heart function, reduced intestinal permeability, and suppressed inflammation in mice in a dose-dependent manner.
