NFKB1 and neoplasm: St-ΔpGlux/pT-ClyA activated TLR4-MyD88-NF-Kb-IL-1β and NLRP3-ASC-Caspase-1-IL-1β signaling pathways simultaneously, which enhanced tumor suppressive effects and inducing increased IL-1β release; these results act to overcome the tumor recurrence caused by IL-1β downregulation during late stages of colorectal cancer treatment that are a result of treatment with only ΔppGpp S. typhimurium.
