NLRP3 and liver cancer: The Western blot results of tumor tissues revealed that the pyroptosis effect of PPII on liver cancer was associated with the activation of the NLRP3/Caspase1/GSDMD pathway, which upregulates the expression of NLRP3, Cleaved-Caspase 1, GSDMD-N, IL-1β, and IL-18 proteins and downregulates the expression of pro-Caspase 1 and GSDMD proteins.
