摘　　要：Objective:This study aimed to elucidate the influence of IFN-gamma(IFN-γ)in neuroblastoma(NB)cells and reveal its potential underlying molecular mechanism.Methods:The Cell Counting Kit-8,Transwell apparatus,and flow cytometry were employed to assess cellular viability,migratory capacity,invasive potential,and apoptotic rates,respectively.RNA-seq combined with bioinformatics analysis revealed differentially expressed genes(DEGs)and their possible biological functions.Protein levels were determined by western blot analysis.Results:IFN-γtreatment resulted in diminished cell viability,mitigated migratory and invasive capabilities,and augmented apoptotic activity in the SK-N-BE(2)cell line,whereas it exhibited the opposite effect in SH-SY5Y cells.Furthermore,interferon regulatory factor 1(IRF-1)was the common DEG in both IFN-γ-treated SK-N-BE(2)and SH-SY5Y cells.Additionally,we found that it was underexpressed in NB tissues.The depletion of IRF-1 promoted the progression of both SK-N-BE(2)and SH-SY5Y cells.Moreover,IRF-1 knockdown effectively counteracted the effects of IFN-γon SK-N-BE(2)cells,while exacerbating them in SH-SY5Y cells.Conclusion:This study verified that IFN-γexerted a distinct role in both N-Myc-and non-N-Myc-amplified NB cells,partially by mediating the expression of IRF-1,suggesting that it may serve as a potent agent for treating patients with NB.
