The Investigation of Nfκb Inhibitors to Block Cell Proliferation in OSCC Cells Lines

Background: Oral cancers, with oral squamous cell carcinoma (OSCC) as the predominant type, have a significant impact on morbidity and mortality rates. Therefore, targeting the NFκB pathway shows promise in cancer therapy. Materials and Methods: This study investigated the impact of two NFκB inhibitors, LY2409881 and MLN4924, on cell proliferation, apoptosis susceptibility, and in vivo tumorigenesis in OSCC cell lines CAL27 and SCC15. Results: The results revealed that both LY2409881 and MLN4924 effectively suppressed cell proliferation, induced apoptosis, and arrested the cell cycle at the G2/M phase—a phenomenon likely associated with the NFκB pathway. Furthermore, MLN4924 demonstrated potent inhibitory effects on cell proliferation at low μM concentrations, surpassing the effectiveness of LY2409881 as an inhibitor. (All results: p<0.05) Conclusion: These findings highlight the potential of LY2409881 and MLN4924 as novel therapeutic agents for OSCC, thereby offering new insights for the clinical management of this condition.
