Numerous efforts have been devoted to discover natural compounds for combating cancer, which showed great potential in cancer management. Methylsulfonylmethane (MSM), an organosulfur dietary supplement, is utilized for improving various clinical conditions, particularly osteoarthritis. MSM can exert antitumor activity in a wide range of cancers. Objectives: The molecular mechanisms of action underlying antileukemic activity of MSM remain unclear. In this regard, we aimed to investigate the anticancer properties of MSM on human AML cell lines (U937 and HL60) with focus on underlying cell death mechanism. Methods: Anticancer activity of the MSM was examined employing MTT assay, Annexin V-PE/7AAD staining, caspase3/7 activity test, and real-time qPCR. Both cell lines were treated with different concentrations (50–400 mM) of MSM for 24 h. Pretreatment of the cells with a caspase inhibitor (i.e., Z-VAD-fmk) was performed for the assessment of apoptosis induction. Results: The results of MTT assay revealed that in both cell lines, the MSM markedly reduced cell viability in comparison to the control cells. Additionally, findings of Annexin V-7AAD staining revealed that MSM induced apoptosis and activated caspase 3/7 in both cell lines markedly. Real-time quantitative PCR results also supported the induction of apoptosis in AML cells. MSM altered the expression levels of various apoptotic genes (BAX, BAD, and BIM).

Experimental doses of miR-669f-5p agonist exhibited no obvious effect on cognitive function following sevoflurane inhalation, but inhibiting the expression of miR-669f-5p could alleviate the impairments. Based on the results of the bioinformatics sequencing, miR-669f-5p/Dctd and the toll-like receptor (TLR) signalling pathway could be the key miRNA, gene and pathway leading to postoperative cognitive dysfunction following sevoflurane inhalation. The aged mice showed significantly increased expression of miR-669f-5p in the hippocampus following sevoflurane inhalation, and upregulating/inhibiting its expression could increase/decrease TLR expression in the hippocampus. Furthermore, miR-669f-5p could reduce the expression of the Dctd gene by binding to its 3′untranslated region.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The miR-669f-5p/Dctd axis plays an important role in sevoflurane inducing cognitive dysfunction in aged mice, providing a new direction for further development of therapeutic strategies concerning the prevention and treatment of cognitive dysfunction associated with sevoflurane anaesthesia.</p>\u0000 </section>\u0000 </div>","PeriodicalId":12657,"journal":{"name":"Fundamental & Clinical Pharmacology","volume":"38 6","pages":"1031-1044"},"PeriodicalIF":2.1,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141534178","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}
