Article Title: Alkalization of the intracellular pH reprograms TNF-α signaling from inflammatory NF-κB activation to tumoricidal RIP kinase-dependent necroptosis in cancer cells.
Article Snippet: Tumor necrosis factor-alpha (TNF-α) plays paradoxical roles in cancer, promoting tumor survival via NF-κB activation while also inducing necroptotic cell death.. Here, we identify the intracellular pH (pHi) as a decisive switch that reprograms TNF-α signaling from a prosurvival inflammatory response toward tumoricidal necroptosis.. In both hepatocellular and cervical carcinoma models, alkalizing the pHi with bicarbonate inhibits TNF-α-mediated IκB phosphorylation and NF-κB nuclear translocation while simultaneously activating the TNF-α-driven necroptotic cascade, which is characterized by the sequential phosphorylation of RIPK1, RIPK3, and MLKL.
