In our study, PEITC inhibited the transcription of IL-1β, IL-6, and TNF-α genes in GBM 8401 cells (Figure 2(b)) and may control the progression of GBM through targeting IL-1β or affecting IL-6 on the regulation of signaling pathways by proinflammatory cytokines IL-1β or TNF-α. This evidence concerns the gene TNF and glioblastoma.
